Wireless network load generator address mask manipulation
First Claim
1. A method of so operating a wireless communication system which has a plurality of emulated wireless stations that only transmitted data frames addressed to one of the emulated stations will be received, this method comprising the steps of:
- providing a host system which has a plurality of virtual wireless stations and the capability of receiving data frames transmitted to the host system from a communication peer station;
applying to all transmitted data frames received at the host system an address filter with the capability of identifying a receiver address embedded in each of the transmitted data frames;
comparing the identified data frame address with a base address of the host system; and
accepting into the host system only those data frames with identified addresses that match the base address of the host system.

Abstract
A method and system for using a single wireless network interface to selectively accept for further processing frames transmitted in a wireless data communications network. This allows a host system to emulate the operation of multiple, concurrently active stations in the wireless network. All wireless stations so emulated adhere to the requirements of applicable standard protocols; particularly, in the context of this innovation, with respect to contention for use of the communications medium and acceptance for further processing of frames transmitted on the medium to an emulated station from a communicating peer station. Each emulated station is assigned a unique address in accordance with the applicable standard protocol, which satisfies the characteristics of a programmable, masking address filter. The address filter allows the interface to accept frames addressed to a conforming emulated wireless station while ignoring other frames. This technique is useful in the creation of efficient systems which may thereby provide interface to the wireless medium concurrently on behalf of multiple emulated stations, giving the appearance from the network standpoint of multiple wireless stations which are all in fact operated within a single device.

10. A wireless communication host system which comprises:
-
a plurality of emulated wireless stations, each of those stations having the capability of accepting data addressed to it in a frame transmitted from a peer station to the host system; and
an address filter for rejecting all data frames which;
(a) are transmitted from the peer station to the host system but (b) are not addressed to a virtual station of the host system. - View Dependent Claims (11, 12, 13)
