Abstract

A repeater system of a wireless network includes at least one adaptive repeater module and a personality module. The adaptive repeater module includes a hardware signal path for processing an input RF signal to generate a corresponding output RF signal; and a controller unit including a micro-processor for controlling parameters of the hardware signal path in accordance with a software program. The personality module is removably connectable to the adaptive repeater module, and includes a computer readable medium for storing the software program.

Claims

1. A repeater system of a wireless network, the repeater system comprising:

at least one adaptive repeater module including;

a hardware signal path for processing an input RF signal to generate a corresponding output RF signal;

a controller unit including a micro-processor for controlling parameters of the hardware signal path in accordance with a software program; and

a personality module removably connectable to the adaptive repeater module, the personality module comprising a computer readable medium for storing the software program.

2. A repeater system as claimed in claim 1, wherein the parameters of the hardware signal path comprise any one or more of:

a gain of the hardware signal path;

center frequency of a pass-band of the hardware signal path;

a bandwidth of the hardware signal path pass-band;

a stability margin of the repeater system;

a frequency offset between the input signal and the output signal;

3. A repeater system as claimed in claim 1, wherein the controller unit is operative to detect a presence of the personality module, and automatically load the software program.

4. A repeater system as claimed in claim 1, wherein the personality module comprises an authorization engine for verifying whether of not the repeater system us authorized to use the software.

5. A repeater system as claimed in claim 4, wherein the authorization engine is operative to verify whether of not the repeater system us authorized to use the software based on any one or more of:

a device identifier of the repeater system;

a predetermined expiry date;

a predetermined authorization period.

6. A repeater system as claimed in claim 1, comprising a plurality of adaptive repeater modules coupled together by a passive link for bi-directional RF communications, the plurality of adaptive repeater modules comprising:

an adaptive donor module (ADM) having its respective hardware signal path coupled to the passive link and to a donor antenna for RF communications with a base station of the wireless network; and

one or more adaptive coverage modules (ACMs) having its respective hardware signal path coupled to the passive link and to a respective coverage antenna for RF communications with wireless terminal devices within a coverage area of the repeater system.

7. A repeater system as claimed in claim 6, wherein two or more adaptive coverage modules (ACMs) are cascaded in series.

8. A repeater system as claimed in claim 6, wherein two or more adaptive coverage modules (ACMs) are connected to the ADM in parallel.

9. A repeater system as claimed in claim 6, wherein the controller unit of each adaptive repeater module is operative to detect a presence of the personality module, and automatically load the software program.

10. A repeater system as claimed in claim 9, wherein the respective controller unit of each adaptive repeater module is coupled to the passive link for bi-directional communications using a predetermined control channel.

11. A repeater system as claimed in claim 9, wherein the personality module contains software program code for each adaptive repeater module of the repeater system, and wherein the controller unit of each adaptive repeater module is operative to transmit the software program code to each one of the other adaptive repeater modules of the repeater system, via the control channel.

12. A repeater system as claimed in claim 11, wherein the personality module contains a version code associated with the software program stored in the computer readable medium, and wherein the controller unit is operative to transmit the version code to each one of the other adaptive repeater modules of the repeater system, via the control channel.

13. A repeater system as claimed in claim 11, wherein the controller unit of each adaptive repeater module is operative to:

compare the respective version code of a local personality module with a version code received through the control channel; and

load the software program associated with the most recent version code.

14. A repeater system as claimed in claim 1, wherein the adaptive repeater module further comprises a control channel transceiver adapted to enable control channel signaling between at least the controller unit and a remote device.

15. A repeater system as claimed in claim 14, wherein the control channel transceiver is connected to either one of:

a control channel bus of the adaptive repeater module; and

the controller unit.
