Cisco Catalyst 3750G

Things get even more interesting with Cisco's WCS (wireless control system) software, as this provides a full mapping service, allowing you to keep a close eye on the location of APs and wireless clients. The Aironet APs provide RF signal strength measurements, which are incorporated into a central database and used by WCS to identify wireless client and AP locations. Importing drawings of your building layout into WCS allows you to customise it and provide accurate heat signature-style mappings of radio coverage and even signal leakage through windows.

Cisco's additional location-tracking appliance allows you to track wireless clients and build up a map showing location and movement. The system uses features such as RF fingerprinting and can highlight the physical location of rogue access points and networks. However, the possibilities go way beyond this, as combining these with third-party products and technology such as RFID tagging allows you to create a complete tracking system for goods and company assets.

During testing, we found the 3750G extremely interesting to work with thanks to its easy management and range of wireless security features. The price tag puts this device firmly in the mid-sized business and enterprise sectors, but small businesses should note that Cisco also offers a lower-cost 2106 controller, which delivers a similar level of features and supports up to six access points.
