CrownCom (Cognitive Radio Oriented Wireless Networks & Communications) 07 will be held next week in Orlando from July 31-August 3. The technical program is available here.
James Neel from CRT will be in attendance and will present “Interference Reducing Networks” in Session 2-A (afternoon on the 1st) and will chair session 4-A (afternoon on the 2nd). The paper and the presentation slides will be available for download on CRT’s Publications page.
Problem 1 (sponsored by the SDR Forum Public Safety Special Interest Group) involves communications from an infrastructure-damaged area, whereby teams must demonstrate a smart radio system that can automatically extend the existing communications network so that voice communications can be relayed to and from the incident site and the communications infrastructure. Student teams will demonstrate a cognitive radio system (hardware and software) operating in the 2.4 GHz ISM band with individual remote radios capable of knowing when they have been disconnected from the existing infrastructure.
Problem 2 (sponsored by the Forum’s Cognitive Radio Working Group) concerns automated spectrum mapping. Here the challenge is to develop a smart radio system that can effectively communicate information on spectrum utilization through a cooperative spectrum access protocol. Teams will develop a secondary-user cognitive transceiver system that can detect primary-user signals operating in the 2.4 GHz ISM band and determine the occupied spectrum, transmission times and geographical locations to sufficient resolution to avoid interference with legacy systems while operating within that band.
Problem 3 (sponsored by the Forum’s Design Process and Tools Working Group) sets up a scenario in which a manufacturer of wireless products is developing a next-generation access point for broadband streaming media in the home. Students must design a smart radio terminal and a rapid development model defining sufficient software and firmware infrastructure to allow new air interfaces to be quickly added to the platform. Teams will be given a specification for an air interface standard supported by a Forum radio that will be transmitting a secret message; the first team to decode this message and transmit a suitable response will be deemed the winner.
