- The Institute of Electrical and Electronics Engineers (IEEE) published the 802.22 standard for Wireless Regional Area Networks (WRANs), designed to make wireless Internet widely available in sparsely populated areas.
- The new standard sends and receives data in the so-called “whitespaces,” the places in the UHF and VHF spectra between TV broadcast signals.
- IEEE claims the standard will allow transmission of data at speeds of up to 22 Mbps, and will be able to communicate over distances as great as 100 kilometers without interfering with reception of existing TV broadcast stations.
- In addition to channel specifications, the standard addresses “the required cognitive radio capabilities including dynamic spectrum access, incumbent database access, accurate geo-location techniques, spectrum sensing, spectrum etiquette, and coexistence for optimal use of the available spectrum.”
