tetherless/tal

Does anyone remember of a wireless hardware company called Tetherless Access Ltd. (TAL, now defunct) back from a few years ago?
Recently, I was offered access to some of their old amps., and I wonder whether with little tweak/hacking it would also work on wifi (within FCC limit, of course). I believe they used 2.4GHz as well (most likely not 802.11b, tho). But can't find anything on the specs.
Would appreciate your comment/thought before going ahead & pay for them.

One of the hams on this forum can answer this more authoritatively than me, but I believe if the frequency range of the amp is correct, it will work with 802.11 products. If it's more than an amp, ie: a radio with its own protocol, you'll have some serious tweaking to do.

Generally, that's true.

TAL had two models of radios that I know about: "L-Band" and "S-Band" The L-Band were 900MHz and the S-Band were 2.4GHz. TAL's S-Band equipment used different channels than 802.11 or 802.11b and is not compatible.

Amplifiers generally don't care about protocols. They only requirements are the frequency range (2.4GHz) and is the bandwidth wide enough to cover the channels being used. Because of the channel spacing that TAL used, the amps may not be wide enough to work properly to use 802.11 or 802.11b/g.

A Google search found this site, which has some of their old mauals in PDF format:

Thanks Thorn & peekitty. Never ceased to amaze me, the kind of knowledge people on this forum have.
