I do have one installation on the end of a 10km link using Motorola's Canopy radios. I didn't install the wireless but it seems to quite reliable in all weather.
Sip seems to be fairly reliable over it, better than the Bell POTS lines to the same site. And much better than the 300m wifi link attempted using consumer gear. Eventually buried cable for that. ----- Original Message ----- From: Bruce N [mailto:[email protected]] Sent: Thursday, May 31, 2012 10:57 AM To: James Knott <[email protected]> Cc: [email protected] <[email protected]> Subject: Re: [on-asterisk] Is it possible to do point to point wireless in a 30km distance? Amazing info everyone. I can't thank you enough as to how much time you saved me. I will go over all the links and start my readings. In the meanwhile I have the following questions: - So, something in the order to 10 Mbps "full duplex" or whatever the term is for "both ways" should be very easily achievable using the equipments mentioned? - Has anyone tested this for telephony application? - How is the round trip delay usually? - Does very cold or hot weather have an effect on the operation? rain or thunder? (e.g. degraded bandwidth or lots of errors in packets?) , has anyone had the issue of directed "intentional" interference or other types of interference which would make this connection any less solid than a DSL or Rogers cable on daily or weekly basis? - What about NLOS solutions? Are there any viable product for that as well? Obstacles could be tree or buildings.
