ROBUST CHANNEL ALLOCATION METHOD FOR RF COMMUNICATION SYSTEMS
First Claim
1. A method of allocating channels in a PTMP (point-to-multi-point) system having a master and a plurality of nodes comprising the steps of:
- a. transmission by the master to the nodes of a synch beacon, the sync beacon having a first frequency and a substantially fixed time period between successive sync beacon transmissions;
b. dividing the time period into a slotted time and an unslotted time;
c. allocating a plurality of slots in the slotted time for RF activity of the nodes that have resolved the sync beacon; and
d. identifying the unslotted time for unallocated RF activity of the nodes that have not resolved the sync beacon.

Abstract
A method of allocating channels in a PTMP (point-to-multi-point) system having a master and a plurality of nodes comprising the steps of: transmission by the master to the nodes of a synch beacon, the sync beacon having a first frequency and a substantially fixed time period between successive sync beacon transmissions; dividing the time period into a slotted time and an unslotted time; allocating a plurality of slots in the slotted time for RF activity of the nodes that have resolved the sync beacon; and identifying the unslotted time for unallocated RF activity of the nodes that have not resolved the sync beacon.

9. A PTMP (point-to-multi-point) system having a master and a plurality of nodes, the system having an allocation of channels, the system comprising:
-
a. a synch beacon transmittable by the master to the nodes, the sync beacon having a first frequency and a time period between successive sync beacon transmissions; b. a division of the time period into a slotted time and an unslotted time; c. a plurality of slots allocatable in the slotted time for RF activity of the nodes that have resolved the sync beacon; and
the unslotted time for unallocated RF activity of the nodes that have not resolved the sync beacon. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
