Abstract:
We report on the development of a Wireless Regional Area Network (WRAN) radio protocol which is based on Orthogonal Frequency Division Multiplex (OFDM) and closely follows the IEEE 802.22 specification. The protocol design is targeted for operation in the Very High Frequency (VHF) and Ultra High Frequency (UHF) portion of the radio spectrum. An experimental prototype is assembled and its radio protocol is implemented on the Software Defined Radio (SDR) platform LimeSDR for the frequency bands 52-54MHz, 144-146MHz, and 430-440MHz with a custom-designed radio frontend. AC++ program running on the prototype assembly has been written. A simplified version of the new radio protocol was implemented and first frames were already successfully transmitted.
