Wireless SSID for Data, Voice and Guest Networks

 

 

Introduction

 

 

Cisco uses Three SSID's for the radio frequency (RF) network:

 

 

Data vlan users

Data

Voice vlan users

Voice

Guest vlan users

Guest

 

 

SSID is not considered a security feature. By itself, it allows separation between WLAN networks if they share the same physical area or are in close RF proximity to each other.  This type of situation may occur in offices located in metropolitan areas. SSID helps Cisco users stay within their RF management area.

 

There are some restrictions on the availability of channel numbers in the 2.4-GHz band. Regulations are country-specific, so the number of available channels may vary.Different channel numbers do not guarantee total separation of two devices. Generally, the three non-overlapping channels used are channels 1, 6 and 11. As WLAN technology becomes more popular, it is necessary to check channel availability by doing site surveys prior to installations. Choice of specific antenna types is up to the local theater's support team. However, the 2-dBi Standard Dipole (AIR-ANT4941) antenna is suitable for most locations.
