Wireless 2 GHz AM network -- pro/cons?

[Green Xenon]

Hi:

 

A wireless router is connected to a cable modem. The wireless adapter is external and connects to the computer via USB. The adapter and router have their own own power supplies for maximum amplifications upon reception and demodulation. There is a single radio frequency used by the router and adapter to communicate with each other -- 2 GHz. The modulation is AM. Both the carrier and modulation signals are completely linear. The carrier is always analog and amplitude-modulated. The modulation signal is initially digital but is converted to analog -- via a DAC -- prior to being transmitted on the carrier. Prior to entering the DAC, the digital modulation signal has it's amplitude attenuated until it is just strong enough to be clearly recognized by the DAC and subsequently the 2 GHz AM carrier generator. In the last step before transmission, the resulting AM carrier signal is also attenuated, until as weak as possible while still being intelligible.

 

Obviously, both the router and adapter have their transmitting and receiving ends.

 

On the receiving end, the analog AM carrier signal is amplified [using a 2 GHz amplifier] and is subsequently demodulated. After demodulation, the resulting modulator signal further amplified. Finally, the modulation signal, is converted back to digital -- via an ADC so that the computer can recognize it.

 

On the receiving ends, all of the following entities are built in such as way that they are both omnidirectional AND as sensitive as physically-possible to weak signals:

 

1. The antennas attached to the receivers

2. The receivers

3. The demodulators

 

Given all of the above specs, what would be the benefit -- if any -- of using these devices to connect a PC to a cable modem?

 

 

Thanks,
