Wireless communications arrangements with synchronized packet transmissions
First Claim
1. A communications device including a group of wireless communications modules integrated therein, each of which wireless communications modules is configurable as a master unit in a shared resources network and comprises its own native clock for clocking said wireless communications module independently of the native clock of any other said module, each said wireless communications module further comprising its own baseband controller and a transceiver and being adapted for wireless communication with one or more user terminals by transmission of packets in timeslots defined by said native clock of said radio module, each said wireless communications module further comprising at least one external input through which in use is supplied a signal which is used to substantially synchronize said modules in such a manner that packets transmissions from two said wireless communications modules integrated into the same said communications device are synchronized.

Abstract
A wireless, e.g. radio communications arrangement is disclosed, which includes an access point (12) in which are integrated a plurality of radio modules (20). Each module (20) is configurable as a master unit of an area network (10) and comprises its own native clock (28) for clocking said module (20) independently of the native clock (28) of any other said module (20). Each said module (20) further comprises its own baseband controller (24) and radio transceiver (26) and is adapted for wireless communication with one or more mobile terminals (16) by transmission of packets a,c in timeslots defined by said native clock (28) of said module (20). Each said module (20) further comprises at least one external input (18, 180; 30), through which in use is supplied a signal which substantially synchronizes said modules (20) in such a manner that there is no partial collision between packets transmissions of two said modules (20) integrated into the same said access point (12).

15. A method of operating a radio communications device which includes a group of wireless communications modules integrated therein, the method including:
-
a) configuring each said wireless communications module as a master unit of a shared resources network;
b) clocking each said wireless communications module independently of any other said wireless communications module in said group by using a respective native clock for each said wireless communications module;
c) engaging in wireless communication with one or more user terminals by one or more of said wireless communications modules transmitting packets in timeslots defined by said native clocks; and
d) substantially aligning said timeslots between said wireless communications modules. - View Dependent Claims (16)
