Wireless technologies are rapidly advancing in Enterprise Networks and Cisco is a major player in this area due to their own internal developments and series of strategic acquisitions. Network designers should understand basic wireless LAN concepts to be prepared for possible network upgrades, even if the network is not initially designed to integrate wireless technologies. Wireless networks can include a wide variety of technologies:

- GSM – low data rates, 9600 bps
- GPRS – up to 128 kbps
