Abstract

Methods and systems are disclosed for realizing MBRI networks and network devices using commercial off-the-shelf components (e.g., chipsets) conforming to the 802.11 networking standards. In particular, a physical layer is provided at or below the medium access control layer that adapts the lowest level of a hardware chipset to the MBRI protocol. Also disclosed are methods of managing and operating an integrated MBRI router that supports a tightly or loosely coupled WiFi MAC and PHY layer operations in an all-IP mobile ad hoc network (MANET) with carrier grade network performance and improved spectrum utilization through IP transparent routing, media access control and physical layer convergence protocols.

Claims

1. A method for implementing an ad hoc wireless router function in an 802.11 chipset, comprising:

configuring the chipset to disable CSMA/CS processing;

configuring the chipset into slotted TDMA mode; and

configuring the chipset to implement an extended API for;

passing packets between the MAC and PHY layers using at least a timeslot;

exchanging at least an RSSI parameter and a timeslot number parameter; and

providing a 1 pulse per second timing signal.

2. The method of claim 1, further comprising:

disabling ACK/NAK handling; and

disabling RTS/CTS handling.

3. The method of claim 1, further comprising:

disabling DIFS processing

4. The method of claim 1, wherein configuring the chipset to implement an extended API further comprises:

exchanging a SNR parameter.

5. A method of managing and operating an MBRI router in a network with a plurality of wireless nodes and a plurality of wireless communication links connecting the plurality of nodes, the method comprising:

transmitting a channel hold signal to prevent at least one wireless node from transmitting.

6. The method of claim 5, wherein the channel hold signal transmitting occurs within two DIFS windows in advance of a data transfer.

7. The method of claim 5, wherein the wireless communication links are WiFi links.

8. The method of claim 5, further comprising providing real-time and non real-time downloading of node specific and network specific protocols for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.

9. The method of claim 5, further comprising providing real-time and non real-time downloading of node specific and network wide applets, servlets, and client applications for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.

10. A method of method of managing and operating an MBRI router in a network with a plurality of wireless nodes and a plurality of wireless communication links connecting the plurality of nodes, the method comprising:

coordinating neighbor interference using DySAN over about a 20 MHz RF channel bandwidth.

11. The method of claim 10, wherein the wireless communication links are WiFi links.

12. The method of claim 10, further comprising providing real-time and non real-time downloading of node specific and network specific protocols for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.

13. The method of claim 10, further comprising providing real-time and non real-time downloading of node specific and network wide applets, servlets, and client applications for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.

14. A method of method of managing and operating an MBRI router in a network with a plurality of wireless nodes and a plurality of wireless communication links connecting the plurality of nodes, the method comprising:

coordinating neighbor interference using DySAN over about a 2.5 MHz RF subchannel bandwidth operating between existing wireless communication link channels.

15. The method of claim 14, wherein the wireless communication links are WiFi links.

16. The method of claim 14, further comprising providing real-time and non real-time downloading of node specific and network specific protocols for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.

17. The method of claim 14, further comprising providing real-time and non real-time downloading of node specific and network wide applets, servlets, and client applications for linking one or more MBRI nodes and end user nodes with at least one of a WiFi network, a WLAN, and a WiFi based Public Safety network.
