The purposes of an educational organisation may often require it to receive guests from other organisations, both from within the education community and outside. Researchers, teachers, students and conference delegates may all come to the organisation from elsewhere and wish, or need, to use the host organisation’s network facilities. Where guests come to the host organisation for purposes connected with its publicly funded or educational remit, Janet Policies allow the host organisation to provide them with access to Janet should it choose to do so.

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.
