So with all the new developments we’ve seen across the board, etc. (all except for V8! =P) what kind of range are you guys shooting now?
We just hit our first long shot today. Most of ours were under 10 miles previously. We’re using 900MHZ and our AP’s are up 175ft. this SM is up 100ft. in Central Florida…
Session Status REGISTERED Registered AP 0a-00-3e-91-82-60 RSSI 1230 (-81 dBm) Jitter 2 Air Delay 671 (approximately 18.68 miles (98637 feet))

Most of you will shake at -81dBm but we’ve got a few people with -83/84 and they’re working with 100% uptime now for some reason - lol.
What the guys are telling you is that for now it will work, but the 900MHz spectrum will be heavily used all over. I would assume that in less than 6 months you will have:
1) Higher noise floor 2) If using a Omni, then You will loose long rage clients.
But if you are located in Boca of West palm beach, then the probabilities are much less that will happen. It’s a $$$,$$$,$$$ place.
My longest links using ISM bands are: 900 MHz = 52 Kilometer ( 14dbi SU and 11 dbi Base ) Canopy 2.4 GHz = 78 Kilometers (24dbi SU and 24 dbi Base ) Lucent 5.8 GHz = 98.7 Kilometer (34dbi SU and 29 dbi Base ) Proxim
All my antennas are Andrew, except the 14 dbi Cush Craft All with in FCC limits.
Where is that 900mhz shot at? Pretty nice. We used a m2 17dBi yagi.
I understand that it will be heavily used. I also understand that if that doesn’t ruin us - WiMax will. So =)
We’re in Highlands County (Sebring to be exact). We’re going to be trying a few more areas with AP’s etc. because ours currently has a bit of interference with all the other radio equipment on our tower.
I would say that the 900 MHz will be the next 2.4 Ghz in spectrum usage.
My reason are: 1) Manufactures are selling more and more 900 MHz units. Canopy was among the first 900 MHz high bandwidth. Now Ubiquity with high power mini-pci cards, AirSpan, with a 1 MHz bandwidth block super saturated almost no redundancy, Alvarion, etc
2) The real NLOS vs. the NOT so real WiMax NLOS, makes 900 MHz ideal to install in any environment.
3) The price rage of Thousand to Hundreds make it more accessible
4) The beepers are moving away from 930 MHz, making it more usable for other 902-928 users.
But then again, Richard could be right on this. But then again, Their is a frustrated community/users in the 2.4GHz band.
About the 900 MHz Link That link is from one Mountain 2,950 ft high to another 2,100’ under a 600’ valley. I’m assuming that link will stop working with in 6 months.
You are using 17 dbi antenna? That must be one long boom.
Standard Canopy equipment. Advantage 5.4 Ghz APs and standard Canadian made SMs with Canopy reflector dish on the SM side. Both sites are clear los. I made this link tests today, on rainy weather. On a clear day they are allmoast 100 on 1x mode.
Our 900 link is on 13 dbi yagis and is rock solid. I’ll throw on a 120 degree sector on the AP end later. The 2.4 canopy link it replaced was the same distance, but 120 degree sector to 24 dbi grid.
This is what the above mentioned 2.4 link looked like before I unplugged it to go with the 900. It kept reregistering too much for my liking even locked at the 1x rate.
