    57In this hurdle, teams will build a radio pair (transmitter and receiver) that can perform well in the presence of interference. The teams will be provided a baseline transmitter and receiver implementation. The transmitter will take input data from a specified source, packetize it and transmit it using a simple modulation scheme. The receiver module will take the received data and pipe it to a database file. Using these transmitter and receiver modules as starting points, the teams must write their own transmitter and receiver modules that can withstand a set of simple interference types and successfully deliver as many packets to the database over the course of 5 minutes.
    … …  
    2729Evaluation Criteria: Teams will be evaluated on the total number of correct packets received and delivered to the database during the 5 minutes of evaluation time.  Teams are provided Layer-2 packets and are allowed to make their own PHY frames; it is only the Layer-2 packets that get evaluated by the receiver. Teams are reminded that during the implementation of their own radios they MUST use the data input and output methods provided in the baseline radio.

    3133WINLAB has created 16 virtual domains containing USRP2s and USRP N210s. Given the large number of teams participating in the Challenge Hurdles, teams will be assigned specific times at which they may access specified virtualdomains containing USRP2 and USRP N210s. In order to ensure fairness, teams will rotate through different domains, and hence no team will have a significantly larger amount of time on a particular domain compared to other teams.  At the end of each 2 hour time period, teams will be removed from their domain in order to make that domain available for the next team. Teams are advised to plan their development and work according to the schedule slots they have been assigned. No reassignment or additional time slots will be given to any team.

    7476Teams will be ranked according to the number of error free packets they successfully transmit during a 5 minute evaluation run.  The evaluation run will consist of running the interference scenario, then initiating the team's receiver, then initiating the team's transmitter.  In the unlikely event that teams end up with the same number of error free packets, the shortest transfer time will be used to break ties.  A selection of the top performing teams will be chosen as contestants for the DARPA Challenge. Teams not selected may still be able to participate in the DARPA Spectrum Challenge as "Wild Card Teams." Further information related to Wild Card selection will be made available following the completion of the hurdles.
