Wi-Fi, Hams, and Transverters

 

I was looking at the ARRL's band plan and started thinking about the higher frequency microwave bands.  While I know there are some experimenters working on using these allocations, in my limited experience it always seems as if operators are using tried and true narrow band modes such as CW and SSB.  I haven't worked out all the math behind it yet, but I'm thinking that it might be possible to build a transverter to upconvert a standard Wi-Fi signal to one of the higher frequency ham bands, such as:

  • 47.0-47.2 GHz
  • 78.0-81.0 GHz
  • 122.25-123.0 GHz
  • 134-141 GHz
  • 241-250 GHz

 

Frequency Allocation

Bandwidth

Could Fit How Many Wi-Fi Bands?

47.0-47.2 GHz

200 MHz

2.4

78.0-81.0 GHz

3000 MHz

35.9

122.25-123.0 GHz

750 MHz

8.9

134-141GHz

7000 MHz

83.8

241-250 GHz

9000 MHz

107.8

 In these bands, there should be much less crowding and you have the ability to upconvert a wide band signal (such as the 84.5MHz wide Wi-Fi band in the United States).  There are already similar products used to upconvert the 2.4GHz ISM band to 5.8GHz in production that use the 2.4 GHz frequency as the IF input.


Lots of other things that I haven't though about including cost, propogation and all of that I'll leave to someone else.  I just think that with such a crowded 2.4GHz band, it might be useful to use higher frequency allocation for such high bandwidth tasks as linking EOC centers, creating data links between hilltop reapeater sites, or just because it can be done. 

As I type this I am paying $12.95/day for Wi-Fi at the hotel I am at.  *SIGH*
