This paper introduces the architecture of a base station designed for a new Wireless Local Area Network (WLAN). The emphasis is on the software but also backgrounds for the design choices made are discussed. The main design objective has been to develop a simple and low-cost system while maintaining suitability for a large variety of applications, ranging(More)
Frequency optimization is required to maximize the WLAN throughput in environments where several networks coexist. This paper evaluates four throughput estimation models and two optimization algorithms. Throughput is selected as the optimization criteria for channel assignment. Thus, the result of a throughput estimation model is used as an input for an(More)
Just a few years ago, enterprise Wi-Fi networks were planned with coverage and perhaps interference in mind. The number of wireless devices and the amount of transmitted data was small and users could tolerate an imperfect Wi-Fi network. Today, 802.11 networks should be designed primarily for capacity. The key drivers of improved network capacity and(More)
