You can sometimes find the older Cisco Aironet boxes that run at 900Mhz. That frequency is AWESOME in rural areas. Mountains will still block it, but trees and water does not.

The old analogue cordless phones have much better range than 2.4GHz digital stuff. This is also one reason why DECT, operating at 1.9 GHz can sometimes work better than Wifi at 2.4 GHz in the same location. It's even worse with 5.8 GHz wifi type A. Of course, the old 900 MHz stuff has great propogation qualities. That why so many people paid so much for the spectrum once reserved for VHF TV channels, but soon to be used for other things.

Re: [asterisk-users] Recommend Wireless IP Phone
naturally wooded does not bode well for WiFi True, and it's even worse for the 5.6 GHz stuff that most of DECT is using these days! The marketing departments have everyone convinced that bigger frequency numbers are better. For most real-world environments the exact opposite is true. The only advantage I know of for higher frequency is more available bandwidth and less congestion. If the road is fairly straight More like a boomerang going around the highest part of the hill. You may be better off with something that uses lower frequencies True. I have an Engenius high power 900 MHz unit that covered the property fairly well and about half of the road, and that with the base station in the walk out basement at about the lowest point on the property. Unfortunately it went up in smoke one day. Also in a POTS environment it could only work with one line. We'll see what this setup does with appropriate location of the base.

Maybe I'll share more when I actually get it all put together. I think you will get better range and longer battery life from a DECT phone though... Probably more features and better quality also! Any of the panasonic DECT phones seem to work very nicely (speaker phone, features, R key works for call transfer, handset intercom etc - mine lasts up to a week on a single charge and light use) and there are several Siemens DECT phones with a builtin SIP gateway which avoids the need for an external adaptor box It's definitely possible to make wifi work for half a mile and you don't even need a 600mw transmitter to do that - however, wifi is all about receive strength, and so you are unlikely to get a significantly better coverage with a high power hotspot which is suboptimally placed. If you do go that route then getting the antennas into a location where 90% of the signal isn't already killed going through walls before it has to travel some distance is the trick. Probably also consider a repeater of some sort rather than just one high power device Good luck though!

Both are basically good devices, but each has its little issues. The S675/685IP supports G.722 which is great! But it has no mute button, which is a drag. Also, its less expensive. The snom m3 is smallish in the hand, or so my wife tells me. It's also a little too easy to turn the handset off by accident. However firmware development at snom is progressing nicely. Aastra and Polycom have new SIP/DECT offerings targeting SMBs. Have not had a chance to try these yet.

Truth be told, I hate that there's no mute button. Also, the handset isn't good enough to make a huge quality difference in g722, at least to my ear. I do believe it has a high bang for the buck value, though. /r ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Most of the hot spots I've tried it on are either firewalled off, or too busy for a successfull VoIP connection to be made.
