What about using an RB411auh and buying a sim card?

Re: [WISPA] Can 900MHz do this?
hi Greg, I see you have several other responses, hopefully you'll get a solution. I would just caution you about assuming it will / won't work in your situation, until you try it. (I realize you can't really try it without the equipment) I'll just give one example from a few years ago: I was trying to make a connection using Trango 900. No hills were involved. I had an AP mounted 80' up on a silo and a potential customer 1.25 miles away. It wasn't particularly dense trees, I had made other, longer connections that seemed much more difficult. I fiddled with things for several weeks and could never get a reliable connection there. (signal was ~ -90) -John On Apr 13, 2011, at 4:54 PM, Greg Ihnen wrote: I'm just curious what people's experience has been with 900MHz and hills. WISPA Wants You!

Re: [WISPA] Can 900MHz do this?
Thanks for the info about 900MHz. It sounds like it would work. The only thing I can find in country is 2.4GHz and 5.8GHz gear. So I'll have to import the 900MHz if I want it or just go with 2.4GHz.
