TDMA-BASED WIRELESS NETWORKS
First Claim
1. A method for enabling two or more TDMA-based wireless networks to share a communication channel, each wireless network implementing superframes, the method comprising:
- within each network, implementing active superframes separated by one or more inactive superframes and only implementing active superframes when the other networks are implementing inactive superframes, wherein a network only communicates during that networks active superframes and does not communicate during that networks inactive superframes.

Abstract
According to a first aspect of the present invention there is provided a method for enabling two or more TDMA-based wireless networks to share a communication channel, each wireless network implementing superframes. The method comprises within each network, implementing active superframes separated by one or more inactive superframes and only implementing active superframes when the other networks are implementing inactive superframes, wherein a network only communicates during that networks active superframes and does not communicate during that networks inactive superframes.

12. A hub for a TDMA-based wireless network, the hub comprising:
-
a transceiver for communicating with one or more nodes of the network using a communication channel; and a processor for implementing active superframes separated by one or more inactive superframes and only implementing active superframes when one or more other TDMA-based wireless networks that are also using the communication channel are implementing inactive superframes, wherein a network only communicates during that networks active superframes and does not communicate during that networks inactive superframes. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24, 25)

23. A node for a TDMA-based wireless network, the node comprising:
-
a transceiver for communicating with a hub of the network using a communication channel; and a processor for ensuring that communication only takes place during active superframes and does not take place during inactive superframes, the active superframes and inactive superframes having been defined in instructions received from the hub.
