[WISPA] Thank You to WISPA - Education Network in Honduras
Hey All, I wanted to thank the WISPA community for being quite helpful and generous. I have been leading a team to implement/replace an aging wireless network in Honduras for three schools and their volunteer homes. It has been a long year and a half, but it has paid off. They had 9 locations, 800kbps-3mbps throughput, 100-400ms latency, and +20% loss. Now they have: 9 Locations, 12mbps throughput, 1-4ms latency, between 0-2% packet loss at the schools, and 1-10% packet loss at the volunteer homes. In the year after our April 2009 assessment trip we spent time planning, designing, and running dry runs, we still had to adapt to what was 'on the ground.' It was a challenge properly grounding our 40meter tower, installing the equipment at the various locations, battling contractor costs, freak lightning storms, and a last minute show stopper with routing loops. In the end the schools have a better platform for education & technology, and we hope to support them through the entire process of technology in the hands of the kids. I will be presenting the implementation story to a local user group here in Southern California, I will have the presentation recorded if you all are interested I will make the link available. As promised I have some implementation pictures to share. http://picasaweb.google.com/israel.lopez/HondurasAllPics# This was one of the first Wireless projects with Engineers Without Borders, we are quite proud of the people that have volunteered to help remotely, and in country. I personally would like to see more Technology Engineering projects in developing countries, so if you think you can help, visit one of your local EWB Professional chapters, talk to them, see if technology may be something their communities may need. http://ewb-usa.org/chapters.php. In support of technology projects/professionals in EWB I have created http://EWBTechies.org if you become a member, please join and let us know how you want to help!

[WISPA] Channel Recommendation & Gel Filled Ethernet
Hey Guys, Trying to choose the best channel for a new installation. http://ewbhonduras.tumblr.com/post/450395382/1hr-wispy-rf-2-4-capture-from-the-horizontal This is what I see, I attached the WiSPY along with a laptop, and mounted both on the tower we are planning on using for one hour. Then brought the laptop down. Any suggestions? Also, what is the best way to handle crimping gel-filled cat5e cable? We are having a heck of a time with the ends slipping off and the individual conductors slipping out. -Israel WISPA Wants You!

Re: [WISPA] State Education Networks?
I had the chance to befriend a high-school IT guy (Quite stellar IT guy too), and I learned a lot from the processes there. The education system in CA will historically go for Wired/Fiber based plants. Usually due to FUD, about security, reliability, blah blah blah. I hope you can get them to change their mind, especially considering the price difference. Their big hang up may be a political opponent who may respond to any 'public' network problems as: "You see, you get what you pay for, you were cheap and tried (gasp) wireless!" Out here in California, most is T1s/fiber direct into local network hubs those are usually school districts-HQs (smaller loops that way), then those link up to a bigger regional hub, and finally to the main hub; access to the internet originates from a single point for the whole network (afaik, I only know so-cal education nets). They do this so they can implement district wide/state wide filtering, management, etc,. -Israel Kevin Owen wrote: > The State I provide service in (Idaho) is in the process of building a > Statewide Educational Network.

Re: [WISPA] HD Video across Wireless?
How many HD Channels? 720p, 1080i? Is there coax running through the community? Just as a thought exercise, I may get a few HD ATSC Hardware Cards, some hefty boxes, and use VLC to convert the video into a multicast stream, bridge it across the lake/valley, and reconstitute it into something useful on the other end. Depending on how much bandwidth you can get (More the better + future growth), probably looking at at 100MPS link. (If you decide to compress the channels to lets say 15mbps). I heard for awhile that my local cable company was using Winboxes + VLC and Video Capture cards to encode and distribute the analog video for their digital STB for awhile.

[WISPA] Modified Sine Inverter Acceptable
Hey Guys, For running commodity routers, radios, servers on a remote site, is using a modified sine wave acceptable? I have some electrical engineers at the site im working on thinking of putting in a modified sine inverter, and joining them up with a large battery cache. The question we raised was, will a modified sine wave be damaging/problematic for things like a Ubiquti Radio/POE Injector, small WRT54GL router, small switch, and two servers (300-400w each). Let me know. I searched the lists and found this, http://lists.wispa.org/pipermail/wireless/2007-July/027900.html but I didnt see the impact on the equipment there, just UPSes. I am going from: [very dirty mains 90-120v] - [battery charger] - [battery bank] - [inverter] --- outlets, [Equipment Transformers] - [Equipment] Ideas?

[WISPA] Moisture Abatement Techniques
Hey All, So how do you guys avoid getting water/moisture in your gear? I'm going to be standing up a 9 end-point network, with some Ubiquiti (Bullet2, Nanostation) gear, Directional & H-Pol Omni antennas, Polyphasers, Ethernet Lightning Arrestors, etc,. I'm not going to be able to travel to the site again in at least a year; its a rainy part of the world, so I'd like to prevent any damage to the gear as much as possible. Anything I should do to prevent moisture from getting into the gear? Or other protective measures... Teflon on the coax connectors, Electrical Tape on the Edges of the gear? If there was a place I could see some pictures of the implementations that would be good too. -Israel WISPA Wants You!

Re: [WISPA] 10MHz, 5MHz - unstable for voice?
I think what he is trying to say that given a noise pattern on your 2.4ISM band, a 20MHz signal may be in that noise about lets say 25% of your bandwidth footprint. If you decide to drop down to 5MHz and move your center frequency right onto that noise then you might have just put yourself right on top of the noise. It would seem more susceptible to the noise even if you have the power to get over it. In my case; I'm replacing a network that is a 40MHz 802.11G WDS network that works 'decently' 800kbps-3mbps if you have a good day, an 100kbps on a bad day. It makes sense when we dropped down to a 20MHz channel that the performance dropped. *There are other problems that we are addressing, thermal resets, no QoS, no firmware upgrades, cheap equipment, bad design etc,.* This is in Honduras. We noted other ISM2.4 users at around 3km away using a 9dBi omni vpol using WiSPY 2.4x approximately -81 to -78 dbm in some spots on the 2.4Band. HPOL made it much quieter. -Israel Mike wrote: > I should think the opposite is true. Halve the signal, improve > signal to noise 3 dB. Half it again and the improvement is 6 dB > signal to noise.

Re: [WISPA] 10MHz, 5MHz - unstable for voice?
Its not in the field, but it is sitting here in my bedroom looking cool :). I was thinking that using the 10/5MHz bandwidth required one to setup something else. I'm not that familiar with the use of half/quarter rate channels and how that affects the frame transport/packet size etc,. I wonder if it was environment based rather than 'software/configuration' based. If I get some time this evening I might setup the gear again for more focused testing (Testing in the field with volunteers who are cold and hungry dont usually respond well to testing plans). -Israel os10ru...@gmail.com wrote: > Just for kicks I'd try WDS bridged.

[WISPA] 10MHz, 5MHz - unstable for voice?
Hey All, I did some field tests (for overseas volunteer project) with some Ubituiti gear; Nanostation2 & Bullet2HP. One thing that was surprising was the performance degradation when switching from 20MHz to 10MHz/5MHz. Our tests were Raw Bandwidth Tests(AirOS), Video (VLC UDP Stream), Voice (Trixbox G711 Voice Call), and MTR (Latency, Jitter) I still have data to collect and prepare a report for the tech team, but we did notice that when we switched to 10 or 5MHz bandwidth our voice calls was greatly degraded. Only one way; from Fixed to Mobile I could hear the Fixed station easily. Mobile to Fixed the voice was choppy. We started to get packet loss & massive jitter on 10MHz, just going back to 20MHz made the links stable. Fixed Station: On a mountain side - HPOL 9dBI Omni Directional with a Bullet2HP @400mW Mobile Station: 8km away near large body of water - Bullet2HP @400mW w/ 24dBi Directional (HPOL Alignment) -70dbm RSSI Any ideas? We are planning on using 10MHz channels & H-Pol to combat any future spectrum pollution and voice calls over this network is expected. -Israel WISPA Wants You!

Re: [WISPA] DMCA - copyright infringement
AFAIK your assertion that "NAT/DHCP - has no way to know" is not entirely correct. Just how most Cable companies require you to register the MAC address of your modem to tie to your account (DHCP has logs you know), University students sign up for dorm internet using their mac address (which they sometimes rewrite onto their modem), but someone's name is still on the 'account.' This is how I think those 'high exposure' for DMCA (especially university) handle DMCA to Violator lookups. One does not need to open up wireshark and start logging traffic for awhile. Sufficient logs with enough detail (IP & MAC + cross reference against account holder) & accurate timestamps should be enough to identify who is who at what time without violating your customer's privacy of their data. -I Jerry Richardson wrote: > OK so let's play out the scenario. > > Studio wants ISP send a letter to the customer > ISP is NAT/DHCP - has no way to know > Studio gets subpoena > > What now?

Re: [WISPA] Link Planning Software
Actually... If you have the lastest radio mobile it is able to automatically pull down the SRTM3 files. What I did in one case where I didnt have the SRTM file, and I was going to be out in the field I downloaded the files by hand from this site. http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/North_America/ OR from Nasa Direct. And (unzipped) put them in a directory for radio mobile (Same directory as described in the map properties window) And actually I just re-ran my radiomobile program, and its automatically grabbing the SRTM Data (140 sets to be exact) This is what I have setup for my 'internet options' Im running version 9.8.1 Robert West wrote: > Okay, I went through it here and getting the terrain maps is indeed the > place where I give up.

Re: [WISPA] Link Planning Software
Hi Shaddi,
You know what would be cool. Is a few things
* Use the features of Radio Mobile as a basis for radio-propogation
o SRTM3 Terrain Mapping
o Flexible Radio Network Topology (VoiceNet, Master/Slave, etc,.)
o Point to point link analysis
o Visual Coverage
o Might be pie in the sky, but at least a good direction
feature wise, implementation is up to you.
* ANND... Add some wiki style features like a database of Radios,
Antennas
o Radios
+ Spectrum
+ Power
+ Sensitivity
+ etc,.
o Antennas
+ Gain
+ Panel Type
+ Images?
+ Antenna Spread (Polar map)
But I think the easiest thing for you would be to start with the SRTM3
dataset, see if you can render that into a browser so people could do
basic LOS functionality. The added plus for us ("US" being an NGO doing
field installations) would adding extra data points to the terrain data
to get a more accurate reading. (Some areas only get 90m resolution 'i
think' and the USA gets 30m resolution.) So if we could load GPS trails
that would show us the difference between SRTM and the GPS readings we
could do better simulations.
Thats my 2c in the pot.

Re: [WISPA] AM radio tower
Michael, If you get any responses off-list, I would be happy to hear. I have a similar situation, but down in Honduras. I posted nearly an exact question to yours, and the consensus was. 1) Install Noise Suppression, and Shielded Twisted Pair 2) Install only when the Tower is unpowered In my situation we want to use the 1KW AM Radio because of how tall the tower is, our stuff is 2.4 as well but we plan on 5.8 soon. -Israel Michael Baird wrote: > *I've recently been approached about expanding our service to an AM > tower.

Re: [WISPA] Client Internet Filtering Upgrade - WAS: Content Filter Suggestion for School
FYI.. Not every site will want to have the same filter settings. Since you can define multiple networks in OpenDNS, the IP will have to originate from that network to get a specific set of content-filtering. If the request originates from the local DNS server, then you've just inadvertently applied those settings to everyone who might query that DNS server. So you would have to force these 'filtered' networks to only request DNS from OpenDNS servers, and make sure each client has a public IP. -IL Josh Luthman wrote: > I just thought about "how to get around this" and I wanted to share my > thoughts.

Re: [WISPA] Content Filter Suggestion for School
I have to agree. It seem that these hardware boxes that try to do 'all in one' services (Routing, NAT, Firewall, AV, Content-Filtering, Spam)... seem to fall on their face. I know of a consultant buddy of mine who implemented it, and hated every second of it. He is still cursing at it when it fails (AD Connector stops working requiring manual resets of the box, etc,). -IL os10ru...@gmail.com wrote: > I had some very bad experiences with SonicWall and their service/ > support.

OpenDNS works in a pinch.

[WISPA] SNMP Counters Available from Radios
Hey All, I just had a thought re: 900 Mhz across water thread. Which radio vendors(models) have SNMP support for counters like SNR, Noise, RSSI, Radio Errors etc,. Most ive found only show Linux interface statistics, rather than the radio characteristics. Or did you roll your own scripts to scrape data from Telnet/HTTP interfaces into your RRDTool systems (Cacti, STG, etc,.) I'm thinking about 2.4Ghz equipment. Have a good 4th of July!
