Re: [WISPA] On-Call Compensation
Generally, somewhere around 1 to 2 days pay for each week on call is typical--it really does depend on what you're paying your employees. Some guy making $10/hr is different than someone making $80,000. It also does depend on your company. If you're a small mom and pop shop and have a very strong team feeling, you may not be able to afford that premium--and your employees will still be fine pitching in for less. If problems are rare, then 1 day, if occasional, 2 days, and if frequent...well, you may want to examine infrastructure and/or hire night shift :) Also, typically there is some sort of comp-time / flexible scheduling involved here. If not done already, put the investment in various remote access and remote reboot setups so that, barring needing to actually replace equipment, everything can be done remotely. Have readily accessible spares, etc. In other words, make it as easy as possible... Having too-frequent on-call issues because of whatever will heavily impact job satisfaction regardless of what you're paying--at some point, money isn't the issue for most employees. Honestly, I would err on the side of generous on this if at all possible just from the standpoint of employee retention. From what I've seen in the industry, on-call is a major cause of burnout and job dissatisfaction. Additionally, because it sometimes directly impacts and interrupts family / personal time at unplanned moments, often spouses of employees start resenting it as well. A lot of companies do have manditory on-call that is not (directly) compensated so you aren't necessarily atypical if you don't directly compensate or you only do a token amount.

Thanks Patrick. One last question, this does mean that we can buy all 3 meg units, and then upgrade them only as the customers require them to be upgraded, right ? R -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Patrick Leary Sent: Tuesday, November 13, 2007 1:20 PM To: WISPA General List Subject: RE: [WISPA] Alvarion VL TRUTH I realize that others have chimed in with respect to performance, I wanted to officially weigh in on this post with respect to pricing for the BreezeACCESS VL product line. The lowest cost way for a WISP to access BreezeACCESS VL is via the AlvarionCOMNET cooperative program. This program does require some level of quarterly quantity commitment, but that commitment is very low. The lowest commitment level is only 10 CPE per quarter and that 10 units can be made of any combination of 5.3, 5.4 and/or 5.8 GHz CPE. At that level the price per CPE is only $399 and that includes a full integrated unit with built-in 19 dBi antenna and the 20-meter shielded outdoor PoE cable. There is no need with these units to buy reflectors since the included antenna is already high gain. These units also include hardware-based AES (meaning AES can be activated with almost no hit to capacity, unlike those versions that only enable software-based AES and even that comes as an add-on cost). These units also have Alvarion only type advanced features like per CPE distance learning (the AU talks to each CPE at a different power level, enough to maintain the desired performance), adjustable noise floor setting, 3rd generation MIR/CIR and tons of other features that have been listed on this list before. While commitments can be any number 10 or higher, additional price breaks trip per the following levels: Minimum 25 units/quarter: $349 Minimum 50 units/quarter: $325 Minimum 100 units/quarter: $299 Minimum 300 units/quarter: $275 Also, if one signs at any number 25 of higher per quarter we give a signing incentive bonus of your choice of either: - 10 free capacity upgrades for CPE ($1,750 value) - One free upgrade to convert an AUS (I'll explain what that is in a moment) to a full AU (MSRP $3,300) - One free WLP VoIP optimization software upgrade (works on the AU and supports all associated CPE to that AU) (MSRP $2,395) These choices are offered with only a 25 unit commitment and if one signs at 50 then the choices doubles, at 100 the choices quadruple, etc., so basically each 25 brings another free choice. The freebies are also given to members upon referral of another WISP into the program. Also, the AlvarionCOMNET program provides for very low cost capacity upgrades for CPE that can be purchased at any time and in any quantity. An upgrade from 3 Mbps 1 MAC (3 Mbps net down/2 Mbps net up) to a 6 Mbps full bridge (6 Mbps net down/ 4 Mbps up) is a fixed $175. An upgrade that can take a 6 Mbps unit to a 54 Mbps (32 Mbps net) unit is a fixed $250. In order to understand the savings there, consider that a 54 Mbps CPE is typically $1,995 retail. Through the program the maximum would be $824 ($399 + $175 + $250). The idea here is that you do not have to pay for more capacity unless you need it and the subscriber is willing to pay for it. Additionally, the program has mechanisms that create further price reductions based on the collective volume of the entire cooperative (the entire set of all member CPE shipped each quarter). The additional discounts are automatic and are tripped at various levels. I should note also that no billing occurs until the CPE ships each quarter, so there is no advance payment required. When your ship date pops up each quarter (a date you set), then the units are drop shipped directly to you and the billing happens at that point. So what about infrastructure (the AU side)? These units are not part of the program and are purchased normally through your selected AlvarionCOMNET VAR and at any time per your need. There are two types of AUs. The full AU supports all capacity versions of CPE. AUs ship with your choice of sector antenna and they provide net throughput of 32 Mbps (ftp) at the highest modulation. This unit retails for about $5k and the discount you can expect is something you should inquire about with your VAR. The second AU option is called an AUS and it is designed for more rural markets. The AUS retails for about $2,500 and it supports up to 25 CPE and can connect to 3 and 6 Mbps CPE versions. It

Re: [WISPA] On-Call Compensation
Good points Clint. The path I chose was to lead by example, which usually helps moral. I take the evening and weekend shifts personally. I also learned that for monitoring, that I could not always rely on a third party. When someone was on call, would they really be? Did I get the message before the on call person? I felt a better approach was to have some paid weekend hours. For example, each tech has to work one Saturday a month. Thats the day the hard to organize residential job gets done, or the day research and paperwork gets caught up on, or that network documetnation and management, etc. And if an emergency occurs, he gets pulled to take care of it. We rely on Voice Mail heavilly on Weekends, and support on call back only. And if I need someone on a late evening, they get paid time and a half or trade it for a larger number of hours off one day later in the week. Its understood that its the tech's responsibilty to do tech, and will require some evening work. But by doing the monitoring personally, I can make the judgement call on whether its cost justified to pay the tech to go onsite after hours. That may not scale, but for me its the reality of being a small business owner, until I grow large enough to hire for those periods. Also the sceond highest paid person, ios nmber 2 on the list for responsibility, and they also monitor as a backup to me. They may not get the alert at 3am, always, but I'm likely to learn about it a few hours before the start of business, if I miss the message personally. The larger you get the easier it gets to share the load. But with only 1 or 2 techs it is challenging. We also work on it by extendign our hours 8a to 8pm, so there are less hours outside of business hours. (this can be accomplsihed by working 4 long days a week, or staggering the start time of employees).

Re: [WISPA] Which UPS to use?
Does anyone have a source for 24 vDC injectors for PoE? - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com - Original Message - From: Eric Albert [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Tuesday, November 13, 2007 6:09 PM Subject: RE: [WISPA] Which UPS to use? This seems like a good opportunity to lob in a sales pitch of sorts. But I will disguise it as an engineering discussion to appease the tech crowd. I will preface my comments by saying I do not know the original application for which this question was posed. Most of the gear (there are exceptions) in our business, in the end run on DC power. Our radios are a good example. The chassis based BS-AU can run on -48 VDC power supplies and supply the necessary DC voltages to the cards and ODUs. The process of running a UPS (which in application is a battery powering an inverter) only to knock down the 120VAC into DC seems overkill. The process is inefficient, generates heat and can be expensive. This process is commonly known as the double-conversion method. Side bar: some UPS units, not all, don't handle power correction. They will kick on during under/over voltage situations but they do little to correct for the quality of the power. Over time poor AC power quality will chip away at the MTBF of everything connected to it. I have also heard that many of the more popular UPS units have trouble with generators, especially the generators that have automatic throttles. If the quality of the generated power is poor it will burn up the MOVs that are in place at the input side of the UPS. But I digress... I think the Telcos have had it right for some time. Although how they got there is another discussion. But in the end DC power affords you some options. A properly engineered DC power plant will take the brunt of bad power and isolate it from your gear. The rectifiers take the hit so to speak and the batteries don't care. Any power events such as brownouts, surges or blackouts don't get telegraphed to the radio equipment. Another point worth noting is the availability of modular-based rectifiers and battery chargers. Lots of options. (I have even seen hydrogen fuel cell units in place a major POPs. Really cool gear.) One WISP who has employed this design had a long outage that almost drained the batteries. They pulled a pickup truck with a full tank of gas up to the site and topped off the DC string. Others have taken the approach of using wind/solar/hydro/utility. Also, if you can build a POP on nothing but DC, think of how much energy you will save just by cutting out the wasted heat that an inverter (or UPS) creates. If the design calls for a cabinet, chances are you will not back-up the air conditioner. Where does all that heat go during a long outage? (DC fans anyone?) Here is the sales pitch. Alvarion manufactures several options in the DC genre. We have the aforementioned -48VDC PS for the BS-SH chassis solution. When you design a system with one radio family (i.e. VL) redundant power supplies can be implemented at the tower. And now, for the Pièce de résistance, we have a DC standalone power supply for VL. It is the OPS-DC. Its input range is 10.5 to 32 VDC and draws less than 1A at 24VDC. Slightly more draw at 12VDC. The temperature range is -31 to +131F. Why all the hoopla? A DC battery charger with a good deep cycle battery and the OPS-DC could run a VL sector for... well, a really long time. This idea will certainly not work for everyone or for every design. But it sure is fun to imagine the possibilities. I hope to hear some creative responses. Thanks for reading.

RE: [WISPA] Which UPS to use?
Hi Mike, Yes, the OPS-DC could take your 24VDC source and power any of our VL radios. It has a DC to DC converter that provides the properly formed 55VDC component to run the VL radio. You would not need a 24V POE injector. The OPS-DC is the injector.

Hi, Again, you need to be careful... the charging unit in the smaller UPS systems (700, 1000, 1400) is not designed to run for 3-4 days to charge up 10 batteries that were drained from an outage. You will burn up the UPS. I would not recommend more than 4 external batteries on any small UPS. Travis Microserv Mark Nash wrote: Hooked up properly, you should be able to put in as many as you want/have space for. Can anyone share how to hook up batteries in parallel vs. series? Also, once you put in the SNMP card, you can tell it how many external batteries you have. This is a way of estimating how much runtime you will have. It's not accurate, because you're using different batteries than it expects. For 2 batteries, I enter in 4 external batteries for this value. It is as close as I've found you can get it.

[WISPA] VoIP?
Hi all, I want to extend a phone line across my wireless network to put an extension line on my office PBX to my home. My office PBX can connect standard analog, (POTS style), phones to its extension lines. I don't want to spend a lot of $$ on this. I don't wish to replace my existing PBX. I expect I need a pair of small boxes with an standard phone jack on one end and an Ethernet port on the other... Ideas?

RE: [WISPA] ImageStream Routers/PowerCode OSS
I can testify that an ImageStream Rebel Router runs my entire network and allowed me to turn a once nightmare into sweet dreams over night. :) Seriously - it performs flawlessly since placed in the rack. ImageStream is a great product and great people. I understand they have 1st class tech support should you need assistance configuring it as well. You can't go wrong buying ImageStream IMHO.

Re: [WISPA] Horizontal vs. Vertical
Gain comes from coverage area. When comparing them make sure that they have the same horizontal AND vertical coverage zones Maybe this will help: http://www.odessaoffice.com/wireless/antenna/how_to_pick_the_right_antenna.htm laters, marlon - Original Message - From: Mike Hammett [EMAIL PROTECTED] To: WISPA General List wireless@wispa.org Sent: Wednesday, November 14, 2007 7:24 AM Subject: [WISPA] Horizontal vs. Vertical Why are horizontal antenna some times fewer db gain than vertical?

Re: [WISPA] Horizontal vs. Vertical
Are you sure that is accurate? MTI makes several size antenna. You might be confusng dissimilar models? I've seen 1-2 db difference between polarity on occassion, but never 4 db. Horizontal itself, is NOT plaqued by having less DB. It is most likely a circumstance related to the design of the specific MTI antenna in question. However, Horizontal and Verticle POL do bounce differently. One way to receive lesser gain is if the polarity of the received signal is out of polarity. For example, in an Urban environment will tall brick tenant buildings... a / polarity might bounce back as a \ polarity. Where as a --- polarity might just interfere with itself. One idea is that the Verticle pol wave is more likely to slide between building walls or Tree trunks, with the wave being unobstructed, compared to a horizontal. This principle also could be effected differently based on the size of the obstructions and the wavelength of the wave. In practical purposes, in most cases there should be little or no difference between the received signal of a Horizontal or Verticle Pol wave, based on the small wave length. I'm not sure what the wavelength of a 5.8Ghz wave, but its less than 3 inches, considering 900Mhz is around 1 ft or so. But I often wonder... Why companies like Alvarion, Proxim, and Motorola started our making Verticle POL antennas as standard. The most obvious reason was they are less expensive to make, and they tend to have less windload due to their thin design. So its logical to assume... Save dollars on the high volume components, and then use more expesnive and unsightly Horizontal on Lower volume backhauls. But in Urban NLOS environments I have seen slightly better performance with Verticle. So, I guess I';m saying... Waves got a mind of their own, and hard to know for sure, whether its fiction or fact (Verticle vs Horizontal).
