I think the concept of combining functionality into single units and fault tolerant redundancy are mutually exclusive.
I believe more people have had problems with more complicated installs than more simple ones vs. failed components on simple installs. I think a well planned combination of both including redundancy where it counts would be best IMO Scott Carullo Brevard Wireless 321-205-1100 x102 ---------------------------------------- From: "Mike" <[email protected]> Sent: Thursday, October 29, 2009 9:05 PM To: "WISPA General List" <[email protected]> Subject: [WISPA] Fault tolerant tower deployment I have been thinking of putting together a fully fault tolerant tower setup. 1 antenna; two radios. Separate CAT5, separate box. If one radio failed, the other would come on-line. The replacement climb would be taken out of the EMERGENCY category. A complete system would be a 3) 5.8 120 degree sectors, plus 3) 2.4 (or 900 MHz) degree sectors. 6) small waterproof enclosures would contain a router and one of each radio. I know on some of the MT router boards there is a fan header that could be used to energize a relay. Microwave relays are readily available and have acceptable insertion loss. Would a stripline divider like Cameron suggested in another thread be the answer instead? Passive solutions are always better. If the antennas were dual-band, wind load on a tower could really be lowered. Besides redundancy, consolidating wind load would be my goal. Has anybody done anything like this? Can't seem to find any on the net. Am I mad? Mike ---------------------------------------------------------------------------- ---- WISPA Wants You!
