Wireless access point cell ID insertion in frame header

摘要

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.

主权项

1. 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.
