In an example embodiment, a wireless device, such as an access point, employs multiple radios that operate on the same or overlapping channels. For example, the wireless device can be upgraded with a new radio that is compatible with a newer protocol to provide service to newer clients that are capable of employing the new protocol, while also providing backwards compatibility to legacy clients.

Using multiple radios to provide service on the same channel to support a new standard while maintaining compatibility with legacy devices

A technique wherein High Availability (HA) hardware is used to automatically validate control and configuration registers, e.g. automatically generate parity, detect parity errors, and report errors within software-written configuration and control registers of ASIC and IC products. Parity control logic and Masking Registers are utilized to facilitate automatic parity generation and subsequent parity error reporting. The specific location of where the error occurred can be stored to enable software to correct and/or reconfigure the registers. The HA hardware verifies the validity of control and configuration registers coupled to a bus, utilizing idle cycles in addition to valid bus cycles so there is no impact on system throughput.
