1. A circuit, comprising:
- a transceiver device to transmit over a channel a sequence of transmissions that is recognizable by devices employing a first wireless protocol but interpreted by other devices unable to decode transmissions conforming to the first wireless protocol as being a primary user of a frequency band and cease transmissions on the channel.

Abstract
A transceiver to transmit over a channel a sequence of transmissions that is recognizable by other devices that employ a similar wireless protocol. Other devices that have a different wireless protocol are unable to decode transmissions from the transceiver and interpret the sequence of transmissions as being a primary user of a frequency band and these other devices cease transmissions on the channel.

7. A system comprising:
-
a transceiver having a channel selector to select a channel; and
a transmitter in the transceiver using a first protocol to transmit a series of packets over the channel that are substantially equally spaced and of substantially equal duration, wherein the packets are recognizable by devices employing the first protocol but interpreted by other devices unable to decode transmissions conforming to the first protocol as being a primary user of a frequency band and cease transmissions on the channel. - View Dependent Claims (8, 9, 10, 11)

12. A wireless device comprising:
a processor having a scheduler, a channel selector and a radio to transmit at least one packet over a channel selected by the channel selector at a time scheduled by the scheduler to communicate with collocated devices having a same protocol but alert devices having a different protocol to cease transmissions on the channel. - View Dependent Claims (13, 14, 15)

16. A method, comprising:
-
selecting a channel in a radio for transmission;
initiating an operation using the selected channel; and
periodically transmitting a sequence of packets over the selected channel to reserve the selected channel from being used by devices that receive the sequence of packets and are unable to decode transmissions conforming to a protocol used by the radio. - View Dependent Claims (17, 18, 19, 20)
