I posted about the home network in multiple other posts in past. I recent time I switched from Microtik SXT Lite 5 to Power Beam PBE-M5-400. This gave me a jump from 16dbi to 25dbi which gives much sharper beam. I also got a harness & climbed BTS myself (after getting permission from the manager) this time to switch gear. I think I can do a better job than wasting time in finding guys from local WISPs to do it.
An excellent presentation by James Quinn from Facebook on “Being Open How Facebook Got Its Edge” at NANOG68. YouTube link here and video is embedded in the post below.
There should have been a video here but your browser does not seem to support it. Some key points mentioned by James:
