As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.
Managing Small Oﬃce WLAN
An Ideal Solution from D-Link
White Paper May, 2009
The deployment of wireless local area network (WLAN) in a small oﬃce environment is often hindered by the lack of simplicity, stability and aﬀordability. Multiple access points (APs) will require more eﬀort in conﬁguration and management, and the complexity of security settings adds to the burden. With limited resources in a small oﬃce, solutions provided for bigger organizations will be too complicated and not economical.
Personal Area Network (PAN) – interconnection of personal digital devices
Neighborhood Area Network (NAN) – connectivity spread over several buildings
Local Area Network (LAN) – usually connects computers in a single building – this is the one most people have heard of
Metropolitan Area Network (MAN) – public high-speed network with range of about 50 miles
Wide Area Network (WAN) – consists of several smaller networks
Wireless network refers to any type of computer network that is not connected by cables of any kind. It is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using a transmission system called radio waves. This implementation takes place at the physical level (layer) of the OSI model network structure....
