Abstract

Embodiments herein relate to a repeater for time division duplexed signals. The repeater comprises, for each channel of the time division duplexed signal, a pair of access points. The first access point of the pair being configured in a first mode, and the second access point of the pair being configured in a second mode. The pair of access points being linked by a broadband serial wired data connection. The invention further relates to a multi-band regenerator and a network comprising such a repeater.

Claims

1. A regenerator for a multi-band network, the network including a leaky feeder, at least one repeater along the leaky feeder, each repeater having, for each channel of the time division duplexed signal, a pair of access points, the first access point of the pair being configured in a first mode and the second access point of the pair being configured in a second mode, the pair of access points being linked by a broadband serial wired data connection, the regenerator comprising:

an input for receiving and demultiplexing a multi-band signal, the multi-band signal comprising a plurality of signals of different technologies, each technology being carried on a predetermined frequency band;

a plurality of filters, each filter corresponding to one of the predetermined frequency bands;

for each technology, a corresponding amplifier for amplifying the corresponding filtered signal;

for each channel of a time division duplexed signal of the multi-band signal, a pair of access points, the first access point of the pair being configured in a first mode and the second access point of the pair being configured in a second mode, the pair of access points being linked by a broadband serial wired data connection;

a combiner for combining the amplified signals and the channels of the time division duplexed signal; and

an output for retransmitting the combined signals over the multi-band network;

wherein the first mode is a client mode and the second mode is an access mode.

2. The regenerator of claim 1, wherein the time division duplexed signal is related to one of the following standards:

IEEE 802.16 or IEEE 802.11.

3. The regenerator of claim 1, wherein the access points comprise at least one of the following:

an Ethernet port or a Peripheral Component Interconnect card.

4. The regenerator of claim 1, further comprising:

an input port for receiving the time division duplexed signal; and

an output port for retransmitting the channels of the time division duplexed signal.

5. The regenerator of claim 1, wherein each channel is handed off between the first and second access points in accordance with the handoff standard of each technology.

6. The regenerator of claim 1, wherein the network is compliant with one of the following protocols:

an IEEE 802.16 or an IEEE 802.11.

7. The regenerator of claim 1, wherein each repeater further comprises:

an input port for receiving the time division duplexed signal; and

an output port for retransmitting the time division duplexed signal.

8. A regenerator for a multi-band network, the regenerator comprising:

an input for receiving and demultiplexing a multi-band signal, the multi-band signal comprising a plurality of signals of different technologies, each technology being carried on a predetermined frequency band;

a plurality of filters, each filter corresponding to one of the predetermined frequency bands;

for each technology, a corresponding amplifier for amplifying the corresponding filtered signal;

for each channel of a time division duplexed signal of the multi-band signal, a pair of access points, the first access point of the pair being configured in a first mode and the second access point of the pair being configured in a second mode, the pair of access points being linked by a broadband serial wired data connection;

a combiner for combining the amplified signals and the channels of the time division duplexed signal; and

an output for retransmitting the combined signals over the multi-band network.

9. The regenerator of claim 8, wherein the first mode is a client mode and the second mode is an access mode.

10. The regenerator of claim 9, wherein the time division duplexed signal is compliant with one of the following standards:

IEEE 802.16 or IEEE 802.11.

11. The regenerator of claim 10, wherein the access points comprise at least one of the following:

an Ethernet port or a Peripheral Component Interconnect card.

12. The regenerator of claim 11, wherein each channel is handed off between the first and second connections in accordance with the handoff standard of each technology.
