Back in 1991, radio amateurs were able to set a narrowband distance record of 3,982km on 5760MHz utilizing the well-known sporadic transpacific tropospheric duct between the Los Angeles area and the big island of Hawaii. (Reference: http://www.arrl.org/distance-records)
I suppose it will only be a matter of time before some radio amateurs decide to get some broadband equipment on either end of this path and show Cambium how puny a 245km link really is. ;-) …Ron NN5DX From: Af [mailto:af-boun...@afmug.com] On Behalf Of Adam Moffett Sent: Monday, August 10, 2015 9:15 AM To: af@afmug.com Subject: Re: [AFMUG] PTP 650 Sets New Wireless Broadband Link Record of 245km burrrrrrn On 8/10/2015 9:59 AM, Andreas Wiatowski wrote: Maybe it only has the Lite license. ;.> Cheers, ______________________________ Andreas Wiatowski | CEO Silo Wireless Inc.

I know it's a long distance, but what was the throughput limitation? Signal to noise? What were the identified noise sources?

Ran the link at 5, 30 and 45 MHz channels and had receive signals of approximately -76 dBm even while battling some pretty heavy winds. We were running a high-def video link and a VoIP server over the channel. Consistently stayed above 30 Mbps which is what we had designed the link for. The link was established with both PTP 650 and PTP 700. The link came up fast and we were testing out the applications after less than an hour on site. LINKPlanner does take the curvature of the earth (and altitude) into consideration. Join the Conversation Cambium Networks Community Forum <http://community.cambiumnetworks.com/>
