Re: [WISPA] Can 900MHz do this?
hi Greg, I see you have several other responses, hopefully you'll get a solution. I would just caution you about assuming it will / won't work in your situation, until you try it. (I realize you can't really try it without the equipment) I'll just give one example from a few years ago: I was trying to make a connection using Trango 900. No hills were involved. I had an AP mounted 80' up on a silo and a potential customer 1.25 miles away. It wasn't particularly dense trees, I had made other, longer connections that seemed much more difficult. I fiddled with things for several weeks and could never get a reliable connection there. (signal was ~ -90) -John On Apr 13, 2011, at 4:54 PM, Greg Ihnen wrote: I'm just curious what people's experience has been with 900MHz and hills. WISPA Wants You!

Justin, I don't quite understand what you are trying to do, so I can't offer suggestions. Can you elaborate? (I use a Mac generally, and have that configured with several profiles.

Re: [WISPA] Changign DHCP timeout XP/WIn7
Justin, I would think you would want to have it setup to just switch quickly to a static address via profile or script or something. But perhaps another solution would be to use a switch or hub? If your windows computer is plugged into that (rather than directly into a radio), it will keep ethernet carrier and not want to look for a new address every time you switched radios. So it would just keep using the autoassigned one. (I think) I don't use Mikrotik much, I vaguely remember it uses a program that manages radios without using IP addressing? Perhaps that is why your auto assigned 169. address is of any value. Almost all the radios I've used (Trango, Tranzeo, StarOS) you have to use a specific subnet (not auto assigned) to talk to it. So I started out with a system that let me rapidly switch between a few statics and dhcp. Hope that helps. On Aug 20, 2010, at 4:01 PM, Justin Wilson wrote: The whole thing is windows takes so long if there is no DHCP server available. For example, plug into a fresh Mikrotik with no configuration. How long does Windows take to time out if it is set to DHCP? I have timed this at 1.5 minutes. My mac only takes 17 seconds to say “hey there is no DHCP server I will auto assign a 169 IP”. What I am looking for is a way to tell Windows don’t wait 1.5 minutes before you assign a 169 IP. Only wait 20 seconds or whatever. Sure you can assign a static IP and lessen this time, but assigning that IP takes time to do and undo. The best solution I have seen so far is Barnes’s suggest for a program that lets you change networking profiles. I was hoping someone knew of a registry key you could edit. Something like DHCP_TIMEOUT=20s. Instead of DHCP_TIMEOUT=120s. WISPA Wants You!

Re: [WISPA] Major Disaster
Don't know if this is possible at your site, but can you add a second AP? Just
switch polarity, channels and try to separate the antenna by 10'+
Then start moving clients over until you have them ~50/50.
Good luck.

We run the Tranzeo 902nf radios as APs and the most we can get on them
is about 10-15 clients. After that performance declines rapidly. How
you ever got 50 on there is amazing. We have since moved to a MT AP
using a zcom gz901 card, and the performance has been much better.
Tranzeo radios just never scale very well. Had the same issues with
their TR-6000 2.4 APs. I would reduce the client count down to 20, and
see how the performance is. What are you seeing on the stats page under
the UMAC tab? Percentages of failed packets? Do you have a hard time
getting to the web interface for the AP? What firmware version on AP
and clients?

Re: [WISPA] 5MHz Channel Drawbacks?
I use 5MHz channels and like them. One thing I have worried about, but maybe hasn't been a problem: if someone else is scanning for regular WiFi channels, they won't see my 5MHz ones. So they might pick a channel that overlaps my gear. Generally my S/N ratio is high enough that I haven't noticed this being an issue. Oh, another minor issue is that I don't have a laptop that works with 5 / 10 MHz channels. So if I pull up to one of my grain legs, I have to setup a radio and work thru that. It would be nice to have a regular WiFi channel at the tower for convenience. The StarOS people do have an Atheros driver that supports 5/10MHz channels, but my favorite laptop doesn't have an Atheros radio.

Re: [WISPA] Holy cow!
Mike, First, take everything I saw about this with a grain of salt, because I'm no expert. From my reading of the RO, there are two types of whitespace device. There is a low power version, that I think is intended to be like a mini-PCI card, installed in a laptop. There are no height restrictions on that. Probably of more interest to us are the higher power devices (up to 4 watts, I think). Those are limited to antenna heights between 10 and 30 meters. I don't think the AP is special, it also has to be minimum 10m high. So it couldn't be on the ground. Personally, I wonder about this 10m minimum. Since all the devices are networked, I would argue that maybe 50% of an APs clients could be lower. One of the higher radios could pick up a new tv signal and force the whole AP to move channels. That would avoid the silly looking large antenna 15' above a single story ranch house roof. Perhaps if this stuff takes off, we could argue for that in the future. (or maybe I'm all wrong, since I'm more a software guy) -John On Oct 23, 2009, at 4:01 PM, Mike wrote: Thanks guys for sharing the height thing. Such restrictions on the production plan won't work. If the goal is to allow such use in an urban setting, the modulation technique would have to be able to survive severe multipath. I'll have to think about the AP on the ground and the client on the roof. Does that make sense? It would certainly keep interference to the AP down. WISPA Wants You!

One could hope that a multipack of those might get under $200 each, later this year? -John PS - not to be a Tranzeo shill, but they are also running a special on the expensive version of 900 AP this month. $300 gets you ssh access into the AP, woo hoo!

Today I just had the need to have one be a client to a Nanostation and I found that the Tomato software wouldn't connect as client (to any AP). I had to put on dd-WRT and use the client bridge mode. I'm using the WHR-HP-G54 in this case because I need the switch ports for a number of devices. But if I was just expanding the network I think I'd use Nanostations or Picostations in WDS.

I know everybody says don't use an omni, but maybe it would be OK on 3.65? I was curious because most of my grain legs would max out at 20 customers (due to trees).

Re: [WISPA] first whitespaces 802.11 card?
Brian, Like Jack says, this is nothing like a whitespaces device. You can download the first draft of the specifications at the FCC, I think it is about 120 pages. The devices are supposed to have a sensing radio to detect existing tv channels, in addition to detecting wireless microphones, and then shift to another open channel. And it is supposed to go over the net to query a database (that doesn't exist yet) as to what channels are open in a given area. Also, you ask about what antennas are available. Speculation was that you would buy a radio and it would be certified with a specific antenna. The certification requirements will be much stricter than the unlicensed gear we are familiar with. And I would suspect the tv people will be looking over your shoulder, making sure you follow the letter of the law. Also, I believe the channels available in a given area are still somewhat in flux. Many stations were going to move around on the transition date, now that is delayed. I don't think the database Brian queried to build his google.kml has the final data. -John On Feb 25, 2009, at 7:18 PM, Brian Rohrbacher wrote: So, is it a card that operates in some of the white spaces frequency then?

Re: [WISPA] TV Whitespaces PtP Backhaul
Could you elaborate on why this is a bad idea? I'm slightly interested in it for low cost connections. In my current area, I don't have a problem finding grain legs for AP sites. These would be dense enough that I could build a great network with white spaces cells and 5GHz backhauls. But if I look farther north in Michigan, the forests are denser and the grain legs disappear. The terrain is flat enough that I can't use mountains for cheap tower sites. And none of the 900-2.4-3.65-5GHz radios are going thru the trees. It seems like a PtP backhaul that would work ten(?) miles thru trees would be a great cost savings over building towers. Maybe use two channels for full duplex. The rural areas that I'm looking at have over twenty channels free. (thanks Brian Webster for your kmz!)

Re: [WISPA] star os help
hi Marlon, I don't know of any paid StarOS consultants. (I get most of my ideas from the StarOS forum at www.staros.com) Are both ends StarOS? If so, I would be happy to look at it for you for free. (but I would only grade myself B based on my two years of using staros -- there are several very sharp people on the forum) If only one end is StarOS, I would still look at it, but am less confident of my abilities. -John Maple River Networks Laingsburg Michigan PS - thanks for your years of hard work supporting WISPs!

Re: [WISPA] coax cables
Chuck, Vegetation might have a huge impact on the coverage area. I've seen pictures of your area, it looks like heaven to me. My experience is that the first two trees will eat up a 5.8 signal, so expanding the coverage area by 80% just adds another tree or two. It might be very sensible for Kurt (?) to use the coax rather than put a little more signal into a bunch of foliage.

Re: [WISPA] CPE radios
Marlon, My best experiences have been with StarOS clients connecting to StarOS APs. Regarding disconnects, I don't see that much. I like to program the client radio's ping watchdog to hit the AP every 10 seconds. Then when I'm in the association page on the AP, all the clients will have less than 10 seconds since they have passed traffic. Any clients that have a minute+ in the far right column get some attention to figure out what is happening. On August 20, at 11:36 AM August 20, Marlon K.

Re: [WISPA] 3.650 Wimax in the field
Mike, This does seem to good to be true. Could you provide more details on these links (for instance, tower heights, or maybe even coordinates that I can look over the path)? I was at a roadshow earlier this year. A Redline rep was there, he said that 3650 wasn't all that great thru trees. Maybe a kilometer. And Ball State U did a research study using 3.5GHz, they had spotty results starting at 3/4s of a of mile. You say these tests were in Ohio, that would seem to be pretty close to Michigan in tree foliage and perhaps topography. These are the sorts of results I've dreamed about, but can't really believe are possible. I was pinning my hopes on whitespaces radios. If you arrange a demo, I would love to drive down and look things over. Also, you mention a PC card ... is someone making a wimax card in 3.65? -John On July 21, at 7:06 PM July 21, Mike Cowan wrote: With some of the Wimax discussions going on I thought I would throw my hat into the ring. 3.650 Wimax using 802.16d only products provides decent connectivity, at a higher cost than traditional unlicensed gear. Performance/coverage is on par, or better than 2.4 that most of are used to. Pay a little extra for product, gain access to cleaner spectrum and hopefully a rule set that helps keep it cleaner than our wild wild west unlicensed world. Now deploy 3.650 using 802.16e upgradeable products. The coverage difference when using diversity options goes up significantly. Now 3.650 begins to act and feel more like a 900Mhz product with NLOS coverage capability. Actually our customers, and our field tests are showing that it exceeds 900Mhz often by a large margin. Here are a couple recent field examples all 2nd order diversity: Customer 1- 8.4 mile NLOS location. blocked by heavy trees . 1.5MB download holding CPE in their hand on the ground! Decided to test 5.8 at this location and @ 50' AGL the CPE got a link. 5.8 mounted on the same tower, same height as 3.650. The 5.8 system could not pass data and could just barely maintain association. Customer 2- 12.4 miles away at the owners home. 1.0mb on the ground. This location could not be serviced by 2.4 or 5.8 at 40' above the ground previously. The owner is going to mount Wimax on the roof and I expect he will se 10-12MB at that height. Customer 2- 12.6 miles on the ground. Completely obstructed 6MB down 3MB up. Customer 3- This is one of the most telling. Canopy 900 operator. 3.650 2nd order diversity mounted 10' below Canopy. 100% coverage at 3.650 of a small city. It takes 2 tower locations with 900 here to serve the same area. They gave up field testing because it works everywhere. They the said lets try to break it. We drove to a part of town that is challenged with 900 coverage. They found a traditionally bad coverage spot and drove up to a big tree, took the CPE out of the vehicle and buried it in the tree. -101 signal. They then picked up their VOIP phone and called the NOC and did a can you hear me now? Toll quality voice call. Our internal testing is showing similar results. Using 4th order diversity is showing even better results than above. When you do the upgrade to 16e and add Wave II CPE, Katy bar the door. That coverage is nothing less than jaw dropping. 2.5 miles obstructed with a PC card! Same PC card 1 mile away entering a commercial building, no signal change. Not possible with a traditional system. In this case the wall measured a 25db loss, however STC and MRC diversity gains completely made up for the attenuation once the paths became uncorrelated. Bottom line is diversity is the place to be with Wimax. It is more expensive, so find a way to afford it. Push your vendor for price breaks and don't be bashful. Alvarion for example is willing to work to earn business as well as the others. CPE costs for D and E systems are the same today, E will be much cheaper in the near future. Not all Wimax is the same, so test a site or visit one, you will walk away amazed. My two cents, and we carry all D and E products. Each has its place.

Re: [WISPA] RSTP problems with simultaneous WiFi + wired connection
I'm not sure what RSTP is and don't want to research it currently, but I can tell you about one painful scenario: a few years ago, Thinkpads (might have been IBM, or maybe it was just after the Lenovo change) shipped with some software that offered to help you manage the wireless networking. If the laptop was plugged into ethernet and then joined a wireless network, it would offer to bridge the connections. Saying yes would create a packet storm on our building network. We had a few of the storms over several months. It seems like that bridging option was dropped from the Thinkpads eventually (or you could switch to windows zero config and avoid it). Maybe do a search on arp storm, I think that is what was happening.

Re: [WISPA] pcb
Tom, One thing I did when I was building StarOS radios was use one mounting screw per board. Partly I was doing that because I thought the board should be grounded to the case, but it also would have helped if the glue failed on the plastic standoffs. Also, I'm not sure what the bad effects would be if the glue failed. The standoffs would prevent the board from shorting out on the bottom, enough other components would prevent it from shorting on the top (probably). The stiff ethernet cable would sort of keep it in position. (in a DCE anyway, maybe a Rootenna would provide too much wiggle room) But I didn't build enough of them, or have them in service long enough to draw any conclusions. Or rather, I came to the conclusion that I hated u.FL connectors; and assembled Lucaya M1208 radios were way better!

[WISPA] Small generators - cheap or inexpensive?
I was looking around for a method to keep at least my backbone running during an extended power outage. (we have had ice storms take out power for 4 - 7 days). It seemed like the small generators might be a solution, the Honda/ etc name brand ones seem to be ~$600 for 1000 watts. And I found a company that sells Yamaha 1000W generators converted to dual fuel (NG or propane) for about $1000. They also sell a 2400 watt generator that is triple fuel, gas/NG/propane that is tempting, even at $1600. But then I ran across some imported 2 stroke, 1000 watt generators. Harbor Freight has them in their catalog for about $150. I found a similar one in a local store that is on sale for $99. The box says it will run for 8 hours on tank of gas (at half load, 1.25 gallons). These imported ones just seem like they are too cheap. And I'm not too fond of 2 stokes. That Yamaha dealer warns that the cheap generators are only designed to last 150 hours - but maybe 150 hours for $100 isn't too bad a deal.

Re: [WISPA] Temporary Telescoping Mast

Re: [WISPA] One Ring Networks To Rollout New WiMAX Service
I ran across this study a few weeks back: http://www.bsu.edu/owrm/article/0,,47997--,00.html Reading the executive summary, in their real world tests, NLOS/indoor radios only worked about one mile. Outdoor mounted radios worked maybe five miles. (I wasn't too impressed, in comparison to the unlicensed gear I'm using) I was particularly interested in this study, since the country they are working in (Indiana) is probably very similar to my country.

Re: [WISPA] Lucaya X-4000 radios
Matt, you forgot to mention one other feature on the X-4000 : FCC Certified I'm a relative newbie at WISP equipment, but I'm just blown away by the price/performance of the Lucaya gear. I was just looking at the store and the M1208 client units are on special for $99 (each, in a 10 pack). Wow! -John On January 4, at 4:17 AM January 4, Matt Larsen - Lists wrote: I did some performance testing yesterday with the new X-4000 radio units from Lucaya and wanted to share the results. These are the new four radio access point/client/backhaul units from Valemount Networks (the authors of StarOS). The latest versions of the firmware now support full duplex operation. I took two units and configured them for full duplex and started running ftp downloads and the starutil speedtest utility to see what the performance looks like. General results were that the boards will handle 30meg in both directions at the same time. If one end is not pushing at full speed, the other end will do more traffic, and that split seemed to max out at 50meg in one direction and 15-20meg in the other. I didn't get any speeds faster than 50 meg. This was using standard 20mhz channels. 40mhz channels didn't seem to do much better as the CPU was maxed out. I'm curious to see what kind of results could be obtained with 2ghz CPU units on both sides using the 40mhz channels. For a $400 unit, I think this is outstanding performance and they are very versatile. I have several up as backhaul links (in regular HDX mode) pulling 25-30 meg at distances of up to 30 miles. I even have one set running on a 62 mile shot that will pull 10-12 meg consistently. They are also great as 5ghz or 2.4ghz access points. We have one that has three 2.4ghz sectors on it and 120 clients between the three sectors. The board is doing an outstanding job and very clearly outperforms the three RB532/SR2 access points that were on the same three sectors before.

Wow, thank you! (really meant to send that message directly to you, but now the list can see your plots, too) It is flat here, but the trees are the problem for RF.

Re: [WISPA] brain cramp, can someone jog my memory?
Say Ralph, I don't suppose your offer extends to others? I've looked at Radio Mobile a few times, but didn't want to invest the time to figure it out. My current method involves using google earth, drawing a line between the two points, then sliding the cursor along it to see elevations (while sort of watching the vegetation). Not exactly scientific! If you don't mind doing a path analysis for me, here's one: Site A: 42°55'59.62N 84°14'55.80W I'm using a grain leg here. Site B: 43° 0'15.15N 84°11'37.26W ( I can get a gigabit ethernet connection here -- well, could only afford 5Mbit, but still ...) I would need to build a tower at site B, but how high does it need to be? It is only a 5.5 mile jump, and the elevation doesn't change much, so I would think 70' might work (enough to clear the trees, plus some). The grain leg is about 80', the connection would be 5.8GHz. If you would be willing to run Radio Mobile with this, I would love to see the results. Might encourage me to spend more time with it. And if not, well thanks for your time and happy new year! -John Maple River Networks, LLC Laingsburg Michigan (PS - started a wisp last year.

Re: [WISPA] Ubiquiti PS2 -- StarOS v3
Mark, What don't you like about the Lucaya enclosures? I have one of the 1208 versions to evaluate. I think I like it a lot. The built-in antenna seems like it should be good enough for LOS customers out to a mile, and with our trees few people would have LOS beyond that anyway. If I want to use a stronger antenna, I can plug in a VAGI (that's what I'm leaning toward currently). And I can set that H or V polarity as desired. I should be able to just stock this single radio and be fully covered for clients in 2.4GHz. Near as I can tell, it is slightly cheaper than the Rootenna parts, arrives ready to install, and is FCC certified. I do like the small Rootenna, but realistically I spent several hours over the weekend putting together just 4 systems (and then testing them). I would be happy to never need to connect another ufl pigtail!

[WISPA] RF propagation map: WiFi vs WiMax?
Just curious if anyone has seen a coverage map that compares WiFi and WiMax? I spent a little bit of time researching WiMax, but decided I would be unlikely to have a license and to just go with what I have that mostly works (unlicensed). But I would like to know what WiMax means in a rural, tree filled environment. As a novice WISP (about 18 months now), I can only hope for good coverage with 2.4GHz to maybe a mile. A rare house might have LOS farther than that, but generally there will be enough trees in the way by a mile to block my signal. (this is using farm grain legs/ silos for the AP, so maybe 150' max AGL) If I switch to 900MHz, maybe the distance gets out to 2.5 miles. Would a 2.5GHz Wimax AP push the signal much better thru trees? I suppose it would make a difference what was at the customer end - a laptop with a WiMax card vs a fixed, outdoor radio. And does AP height help a lot? I don't see an advantage to paying commercial tower rates to get above 200' in my situation, but maybe that changes with WiMax. ** Join us at the WISPA Reception at 6:30 PM on October the 16th 2007 at ISPCON ** ** ISPCON Fall 2007 - October 16-18 - San Jose, CA www.ispcon.com ** ** THE INTERNET INDUSTRY EVENT ** ** FREE Exhibits and Events Pass available until August 31 ** ** Use Customer Code WSEMF7 when you register online at http://www.ispcon.com/register.php ** WISPA Wants You!

Re: [WISPA] Thoughts on 900MHz mesh networks
Allen, It sounds as if you might be proposing this for a suburban or even tree filled urban environment. One problem you might run into is clear spectrum in 900MHz. I've use Trango gear out in rural areas, where it works OK. I've only done a few scans in the city (East Lansing and Lansing, specifically). Both of those scans were so depressing I never tried making any links with 900 in town. All the channels were what the Trango manual calls unsuitable. I have a few of the SR9 cards and am just starting to work with them. I read somewhere that Trango (for example) rejects interference better than the SR9. No personal experience one way or another yet. My new rule of thumb with Trango is that I can go 2 miles. This is with AP's at 80 - 130' AGL, pretty flat ground, but quite a few trees. However, I have been struggling to make a link that is only one mile, unfortunately the path follows a heavily wooded riverbed. So you just never know. I think I've solved this connection by relaying off the house next door (tenth of a mile closer, but with an open field for 1/4 mile toward the AP). But I did notice that there is heavy noise at the relay house in what Trango calls channel 2. Noise level about -67. No idea what is doing that. You might consider a modified mesh structure that uses 2.4 or 5GHz (or even 900 after testing) to those few LOS houses, then something like Meraki mesh to connect close neighbors. Otherwise, I think your idea is great, if you could get clear spectrum. :-) On September 10, at 12:16 PM September 10, Allen Marsalis wrote: Please imagine a muni wireless mesh network that utilizes 900MHz cards instead of 5.8 and 2.4 cards. Instead of nodes being 1000 feet apart atop light poles, they are now spread 1 or 2 miles apart. Instead of it taking 15 or 20 nodes to cover one square mile, perhaps one node could cover 1 to 4 square miles. Could this be a solution for wooded areas with low to moderate population densities? In other words, do you know anyone who has ever built a mesh network using SR9s and SBCs with multiple radios to achieve redundancy and ubiquitous coverage for small towns in the Southeast? And using no towers by the way, LOL? As I see it, the SR9 has 4 non-overlapping channels at 5MHz each. Thats all I need.

Re: [WISPA] T-Mobile [EMAIL PROTECTED]
I did a few tests at the East Lansing Starbucks. I start the call on WiFi and walk out the front door. By the time I'm 20' away it has switched over to a tower. I didn't detect any noise during the switch, but I was outside next to a 3 lane road. Unfortunately that doesn't work at my house. If I move out of Wifi range (currently about 20' from my porch for this phone), it drops the call. I need to move about 7 miles before I can reliably hit a T- Mobile tower. The Starbucks has a T-Mobile Hotspot, the phone usually automatically switches over to WiFi there. (I think that is how it is supposed to work) Still a few bugs in the system: sometimes I have to use the phone menu to search for WiFi at Starbucks, then pick the Hotspot.

[WISPA] T-Mobile [EMAIL PROTECTED]
T-Mobile launched their [EMAIL PROTECTED] service at the end of June. I picked up one of these cell phones a few weeks ago. The deal is for an extra $10/month, you get unlimited calls in the US if they are made over wifi. The wifi connection generally works with any open AP, or if you know the security key you can enter that. It also automatically connects to T-Mobile Hotspots, such as might be found at Starbucks. Once you start a call on wifi, you can move out of wifi range into tower range it seamlessly switches over. The call is billed according to where it starts. I had actually sampled a T-Mobile phone, then returned it the day this [EMAIL PROTECTED] service launched. Most of the places I hoped to use it, I had no signal. But I like this new combo phone quite a bit. For example: my WISP office is in my basement. I've used Verizon cell phones for years, based on having them work almost everywhere I go. But no service in my basement. The T-Mobile phone happily uses my net connection and sounds better than any cell phone I have used. Ditto for a few locations at work, such as a server room. No cell service, but wifi is fine. One thing I don't like is that the phone doesn't include a web browser. If you are at a location that requires agreeing to TOS before using the wifi, you can't do that just using the phone. I've used some other VOIP systems before (Packet 8, Skype, almost went with SunRocket - that was close) but haven't really liked them. -- An idea for WISPA leadership: think about brokering a deal with T- Mobile to expand their hotspots to members POPs. They only have about 7500 hotspots in the US. For example, there are none in Michigan's Upper Peninsula, and the only one in the north half of the Lower Peninsula is Traverse City. Some technical details: The T-Mobile phone uses technology called UMA to encapsulate GSM over IP. The packets are UDP encapsulated IpSec. The call I monitored averaged 60 packets/sec. All traffic was to/from one IP address using port 4500. Bandwidth used was 9516 bytes/second average. Most packets were 158 bytes (the longest seen), a few were 142, and occasionally 60 bytes. -John Would you like to see your advertisement here?

[WISPA] MDU info?
I'm hoping someone here can point me to good info sources on MDU networking. (I did a quick search and didn't find much specifically on multiple dwelling unit) I'm a very small wireless ISP. Right now my Internet source is a DSL on top of a city water tower. I'll need more bandwidth in a few months, and access to the water tower is problematic (call in advance, iffy on weekends, etc). There is a new loft project in this town (80 res units plus a few store fronts), I'm trying to become the preferred ISP for them. The builder is running Cat5 to all the lofts, and I could get a fiber line into the building and reasonably priced bandwidth. I'm thinking a short tower on this 5 story building would link up to a grain leg I have a few miles away, giving my wireless net a faster / better connection to the net. My questions are: * is it typical that the property owner gets a kickback for using his Cat5? * seems like the only equipment I would need for the lofts is a good switch and a router to handle bandwidth shaping? * anything else I could offer that would make my offer more attractive to the property manager? Thanks for pointers to any more details on this line of business. Sorry to hijack the wireless list... -John PS - I have done department level network support for many years (50 - 100 computers). And I'm hoping to stay away from phone and video service for now. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
[WISPA] Re: Mirrored Switch
(reply to an older posting, I'm trying to catch up) Matt, I bought some Dell PowerConnect 2708 switches last fall. That is a smaller 8 port gig switch, it was the cheapest one I could find that did port mirroring. About $82 now, go onto Dell's website as small business or the price might go up drastically (under the EDU section, it was about $100 more). The 2708 is smaller, I wanted to mount it inside a box up a grain leg, so that was what I wanted. They have 16 and 24 port versions. All them come with ears for rack mounting. The 24 port one has two fiber ports. I've had one installed at 140' for about two months now with no issues. The other one is in my basement NOC, guess I'll need to move that to my other POP before CALEA kicks in. (ugggh, this weekend! time flies...) - One concern I had with these is the temperature rating. Only goes down to 32 F. But the switches that were rated for colder were much more expensive and didn't do port mirroring until $300+. But I've had Allied Telesys cheap switches that are also rated to 32 last thru the winter with no problems. (think we hit -20 in February) That SMCGS24C-SMART that Ty Carter mentions also sounds interesting. -John On May 1, at 1:00 PM May 1, [EMAIL PROTECTED] wrote: The basic parts you'll need are: Linux based router or tap capabilities on the on you have. OR a managed switch that will allow you to mirror a port. Does anyone reccommend a good switch that supports this and is rack mount? Hopefully available at newegg.com. Putting together a Linux server is easy but my luck a good switch might be backordered when I need it. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
[WISPA] Useful book from DOJ
This book showed up in my mailbox at MSU one day. I ignored it for a while, but looked it over last week and found some interesting info. Probably most useful to a startup WISP, it has some sample subpoena (s), court orders, etc. Basic info on ECPA, etc. The full PDF is linked from this page: http://www.ojp.usdoj.gov/nij/pubs-sum/210798.htm Investigations Involving the Internet and Computer Networks By National Institute of Justice January 2007 This NIJ Special Report is intended as a resource for individuals responsible for investigations involving the use of the Internet and other computer networks. Any crime could involve devices that communicate through the Internet or through a network. Criminals may use the Internet for numerous reasons, including trading/sharing information (e.g., documents, photographs), concealing their identity, and gathering information on victims. The report is among a series of guides on investigating electronic crime. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
RE: [WISPA] Using DECT phones to avoid interference issues.

I began searching for why the last time a thread discussed the 1.9GHz UL band surfaced on this list. I doubt you'll ever see much product ever emerge for this band in the United States.

Re: [WISPA] 3650, ok, so what's current status?
Jack Patrick: thanks for all the info on 3650 status. This type of response is why I'm on this mailing list. That March 10, 2005 announcement is near-and-dear to me, since that is what started me on the WISP path. I haven't closely followed the progress on 3650, so when I saw the XR3 info I thought it might be happening soon. Those thoughts were pushed along further when I saw the Part-15 org people selling a help get licensed on 3650 manual -- their webpage doesn't indicate to me that it is still experimental. http://www.part-15.org/sales/3650manual.asp Sounds like I should plan testing under my ham license (~3400MHz) rather than clogging up the FCC with a bogus STA application. My interest is propagation thru our Michigan foliage, so I would want to test this summer. But maybe someone could just tell me what to expect - should it be similar to 2.4GHz? -John (kd8bqx) PS - any chance I could convince folks to trim their responses? I read this list in digest mode, 80% of the digest is noise. :-) The Ubiquitu XR3 spec sheet is misleading. As far as I know, there is no current legal license-free 3650 operation allowed, as Ubiquity states. Operation on 3650 can only take place when a Special Temporary Authorization aplication has been submitted to the FCC and an STA approval received back from the FCC. In general, STAs in the Experimental Radio Service are issued to allow on-air testing of equipment or new technology that can only be tested on-the-air. Please see my previous post which outlines the conditions under which an STA may be granted. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
