Abstract Today, access to radio spectrum is frustratingly difficult. The access is restricted by an old radio regulatory regime that emerged over the last 100 years. Large parts of our radio spectrum are allocated to licensed radio services. Open access to most of the radio spectrum is not permitted. However, it is well known that radio spectrum is not efficiently utilized because of the complicated and time-consuming radio regulation process. In this presentation, technologies to help overcoming this barrier, namely, cognitive (spectrum agile) radios, are discussed. Cognitive radios operate in the radio spectrum that was originally assigned to other (incumbent, primary) radio services. A cognitive radio seeks unused radio resources and communicates using these opportunities, without interfering with licensed radios. This presentation provides an introduction into the research area of cognitive radio, and states two main challenges: protection of incumbents, and coexistence. We will focus on our previous work on IEEE 802.11e/k and show how new measurements that are part of the first draft of IEEE 802.11k will assist cognitive radios in coexistence scenarios in the context of spectrum etiquette.
