Abstract
A wireless access point includes a wireless interface to send or receive frames in a cell in a wireless network. A storage device stores a cell ID that uniquely identifies the wireless access point. Processing circuitry inserts the cell ID in a physical layer header of a frame, and sends the frame to a client device in the cell via the wireless interface.
Claims15
A method of receiving a frame in a wireless network, the method comprising:
- receiving a first portion of a frame at a network device, wherein the first portion of the frame includes a physical layer header;
- determining a cell ID in the physical layer header of the first portion of the frame before receiving a second portion of the frame including a payload;
- if the cell ID from the physical layer header matches a stored cell ID, continue receiving a remainder of the frame, wherein the stored cell ID uniquely identifies a wireless access point;
- and
- if the cell ID from the physical layer header does not match the stored cell ID, releasing the network device, before receiving the remainder of the frame, to send or receive another frame.

A wireless access point comprising:
- a wireless interface to send or receive frames in a cell in a wireless network;
- a storage device to store a cell ID uniquely identifying a wireless access point in the cell;
- and
- processing circuitry to:
- insert the cell ID in a physical layer header of a frame,
- send the frame to a client device in the cell via the wireless interface,
- determine a received cell ID in a physical layer header of a first portion of an incoming frame from the client device to the wireless interface, before receiving a second portion of the incoming frame including a payload,
- if the received cell ID from the physical layer header matches the stored cell ID, continue to receive a remainder of the incoming frame at the wireless interface, and
- if the received cell ID from the physical layer header does not match the stored cell ID, discontinue receiving the remainder of the incoming frame at the wireless interface.
