This article describes development of device architecture for wireless high frequency transport networks which operate in millimeter wave range (71 -76 GHz and 81 -86 GHz). Features and issues of this range device design are considered along with applied methods. The example of routing in transport network with duplex frequency channel multiplexing is given. Analysis of influence of signal resolution in digital block of modem, ADC, and DAC and error control codes on modem's proprieties and architecture are presented. Proposed architecture was designed considering methods of compensation of increasing the peak-to-average ratio.

We describe a method for constructing a concatenated error-correcting codec for data transmission in one channel with varying reliability: 10 -6 and 10 -9 , describes the using approach and functional area. It is shown that for current ad hoc networks the most effective approach is to use a concatenated code and information transfer with different reliability in one packet.
