Abstract
The addition of high throughput capability elements to beacon frames and peer link action frames in wireless mesh networks enable the utilization of desirable features without further modifications to the network. Rules can be established for high throughput mesh point protection in a mesh network, Space-time Block Code (STBC) operations and 20/40 MHz operation selections. However, features such as PSMP (power save multi-poll) and PCO (phased coexistence operations) are barred from implementation to prevent collisions.
Claims4
A method for Space Time Block Coding (STBC) in a mesh network having a mesh STBC mesh point and at least one neighboring STBC mesh point, the method comprising:
- determining whether the STBC mesh point and the at least one neighboring STBC mesh point are high throughput STBC mesh points;
- setting a dual clear-to-send (CTS) protection field of a high throughput operation element of the high throughput STBC mesh points to 1;
- and
- responsive to the STBC mesh point setting the dual CTS protection field of the high throughput operation element to 1 and the at least one neighboring mesh point failing to set the dual CTS protection field of the high throughput operation element to 1, the STBC mesh point transmitting as an access point with the dual CTS protection field of the high throughput operation element set to 1 for communications with the at least one neighboring mesh point.
