Re: 700 MHz?
quote:
Not much bandwidth there for a nice high speed internet with multiple users. But then I only operate and repair radios, not make spectrum policy.
An analog TV channel is six MHz wide, isn't it?
Motorola Canopy puts 3 channels between 902 and 928 MHz which are each capable of 3.4x1.2 asymetric. That would be 2.3x2.3 symetric. These channels are each the width of a single TV channel.
I should also say that there are more sophisticated modulation schemes.
It isn't a lot of spectrum but they also suggest that "smart" radios that can avoid channels which are in use will be provided.
We deliver using 900 MHz ISM. 700 will not give us a significantly enhanced capability because there is not that much difference between absorbtion at 700 and at 900; however, it is a move in the right direction. |
