[WISPA] Marlon not awake
Hey Marlon, I asked you for the contact information of the person in Ottawa. (damn it is hard to get good help these days) :o You getting so famous it is hard trying to talk to you. Maybe I should make like I am as famous as you. :-P Just trying to get the ball rolling up here in the Frozen North. But we are little concerned, we have had no snow in our area yet, so to the person who has been hi-jacking our snowstorm, can we have it back, before you used it. :-$ It is Monday I thought I would start the week right ;-) -- You have a Good Day now, Carl A Jeptha http://www.airnet.ca office 905 349-2084 Emergency only Pager 905 377-6900 skype cajeptha -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
Re: [WISPA] Atheros speed WRAP vs RB532
For the profile, I use RadioMobile and export the path to a text file. I then put the first 2 columns into the second tab on the spreadsheet. Works great.

[WISPA] Packet Aggregation
Because a lot of traffic crossing our network is in packets smaller than 1500 bytes I have been playing with Mikrotik's M3P to aggregate the smaller packets together. Throughput wise this seems to work very well and we see a big improvement on the amount of data we can pass over our wireless backhaul. The problem is that M3P adds about 15ms of delay in each direction so you are adding 30ms of delay to most none UDP streams. This is the amount of time that M3P waits to fill the 1500 byte. Does anyone know of an alternative system or open source software that does packet aggregation but is a little more configurable? Ideally I would like to be able to change the amount of time that the aggregator waits to fill it's payload and therefore reduce the overall delay.

[WISPA] 900Mhz Grid vs Yagi
PacWireless makes a 900Mhz 18 dbi Parabolic grid antenna. M2 makes a 900Mhz 17.5 dbi Yagi antenna. We had found that 900 was very particular to placement, even a few inches in one direction or the other can make big differences in link quality. Has anyone used both antenna types for a specific link, to compare the properties of each of the designs. The thought is whether the wider surface area of the parabolic antenna would make it better to survive signal obstruction from swaying trees in forests. The prabolic is a monster at 3 ft dia, s othe Yagi would clearly be a better choice for a roof top chimney install based on cosmetics. But wondering from a performance perspective the comparison.

[WISPA] Insurance / Service Plan Offerings
Title: Insurance / Service Plan Offerings We're coming into our 3rd year of operation soon. I am curious how others are doing combat against the replacement / repair / service call costs associated with having to replace CPE end equipment.

George - that may work in your neck of the woods and I have been doing the same since day 1. This past year - we replaced over $8,000 worth of CPEs - that is almost a full months revenue for us Mind you - we dealt with hurricanes and severe lightning - but - - - we can no longer as a company sustain those types of hits That is 8k in equipment costs - not the additional 5k worth of labor for the trips to the CPE. I am In an area that will constantly have severe lightning issues, hurricanes, wicked thunderstorms and high winds. How many CPEs did you replace in the last 12 months ?

RE: [WISPA] Insurance / Service Plan Offerings
That is what the insurance plan would prevent - They will have a choice to opt out - but if they do - they will be responsible for the cost of a new CPE. If it were only 1 CPE a month - I wouldn't sweat it - but 6 months out of the year - it's almost 8 per month ! I was thinking charging $3.95/mo - if I could get half of my Customer base to pay it - that would be almost $500.00/mo in revenue generated to help offset the expense. Would prevent us from having to go through a rate increase which would be much harder to swallow for a customer I think. Cellular companies / Satellite companies / pager companies - they all have service plans to offset the costs of replacing equipment for a customer - was thinking - why not a WISP ?

I feel for ya JohhnyO, seriously. I've changed out every Smart bridge I ever installed except two and dittto for tranzeos. The EZ Bridges were great for a while, but going past 2 years now with them and we're starting to replace them as well. I'm not sure how many rados I've replaced this year, but it seems lately it's more and more. At almost 700 subs, the replacement rate grows, but then again the revenue does as well.
