Re: Any Idea About Spectrum-DMR-104-1 ?!

There are a lot of factors to consider when trying to use ISM band for high
bandwidth...

1.      What kind of distance do you want to cover?
2.      Is this point to point, or point to multipoint?
3.      Directional or Omni?
4.      Antenna Height, Fresnel Zone, Noise Floor, other path interference, etc.

The 5.725-5.825Ghz band is used by 802.11a/n and is the only unlicensed
spectrum around 5.8Ghz. A 300Mbps symbol rate should be achievable
with wideband channels in that frequency range. As an example, an Apple
Airport Extreme can do better than 150Mbps full duplex on 802.11n/5Ghz.

Dear Friends,
I wanna buy a free license radio with more that 150Mpbs capacity (full
duplex), and I found a company in middle east who has Spectrum-DMR-104-1
available right now, any body has experience about that? Is it really
300Mbps radio?
Thanks
