Abstract
In the present invention a method of re-establishing a wireless communication after a communication break is disclosed. Prior to the communication break, a base unit transmits to a remote unit a table of channels of communication to be used. The base unit also transmits a clock signal value to the remote unit. After a communication break, the remote unit continues to count the clock signals generated from a clock signal source internal thereto. The remote unit applies a function to the value of the clock signal to obtain an entry in the table. The channel of communication associated with the entry in the table is selected by the remote unit. The base unit continues to count the clock signals generated internal thereto. The base unit applies the same function as the function used by the remote unit to the value of the clock signal to obtain an entry in the table. The base unit selects the channel of communication associated with the entry in the table. Thereafter, communication is re-established over the channel of communication associated with the entry in the table.
