This paper considers the application of 5GHz Wireless LAN technology to home networking applications. An assessment of physical layer pevormance is presented for both the IEEE 802.lla and HIPERLANE standards in the form of achievable data rate as a function of received signal to noise ratio. The transmit power limitations imposed by the relevant regulatory bodies are presented and the implications of transmit power amplij?er limitations considered. Based on this information, a state of the art

The achievable data rate and coverage is evaluated for a variety of scenarios and the implications of potential co-residence interference are evaluated. It is found that data rates greater than 2OMbitsh can be achieved with 100% coverage i f the Access Point is well located and the transmit power is high. Even in the case where transmit power is severely limited, data rates in excess of 1 OMbitsIs can be achieved throughout much of the example environment. Adjacent residence intelference is found to have a severe debilitating effect and is thus identified as topic of crucial importance.
