Method and apparatus for providing a wireless mesh network and network node are described. More particularly, a network having network node neighborhoods is described. A node comprises a multi-sectored antenna and a transceiver controller. Nodes are configured for installation without antenna pointing and without pre-coordination with the network. Software architecture for the node is also described.

The present invention is directed towards a look-up table implementation of a WCDMA frame synchronization and a cell group ID detection (both of which are comprised within a 'secondary search' process). The secondary search process receives a signal (which is formatted as slots within a frame) and determines ('decides') information encoded in the received signal according to the slots of the received signal. The determined information is used to produce a sequence of values. A sequence of values (which have been determined from successive slots) is used to produce an index into a table that stores secondary search results. The secondary search codes are arranged such that a minimum sequence of values can be used to determine frame synchronization and group identification. The table is configured to return information that is sufficient for determining frame synchronization and the group ID of the received signal.
