Surveying should be used at three different stages in the deployment of a wireless network.

The basic tools for performing a wireless network survey are therefore a device that can measure signal and noise levels and calculate the signal/noise ratio, and a map of the area to record these values.

Wireless LAN Basics Wireless Frequencies

Wireless networks are a useful complement to a wired network, allowing network connections to be obtained anywhere within an area rather than only at fixed network connection points. However, wireless networks suffer from a number of problems that do not affect wired networks, in particular that the medium they use to transmit packets is a scarce resource subject to physical limits. Whereas the capacity of a wired network can be increased indefinitely by adding more cables, a wired network only has available a finite (and in some cases very small) number of frequencies.

What is mobile networking? Mobile networking refers to technology that can support voice and/or data network connectivity using wireless, via a radio transmission solution. The most familiar application of mobile networking is the mobile phone. In the past, wireless communications predominantly used circuit switching to carry voice over a network; however, more recently both voice and data are being transmitted over both circuit-switched and packet-switched networks.

Scott Armitage, Loughborough University 14 July 2011 Introduction Wireless networks can be affected both passively and actively by the environment in which they operate due to the fact that they use a radio frequency (RF) medium for data transfer.

Wireless networking is virtually synonymous with the deployment of equipment supporting one or more of the 802.11 family of standards. These have experienced a period of rapid growth of use in recent years, and the problems and caveats associated with networking to these standards are well documented. Essentially 802.11 can be viewed as a technology to both supplement and extend the traditional wired local area network (LAN).
