What Is An Essid; What Is The 2.4 Ghz Frequency Range; What Is Server Set Id (Ssid) - ZyXEL Communications P-2612HNU-Fx Support Notes

P2612HNU Fx Support Notes
No. Provided the antenna is optimally designed for 2.4GHz or 5GHz operation. WLAN
NICs often include an internal antenna which may provide sufficient reception.

What is the 2.4 Ghz Frequency range?

This frequency range has been set aside by the FCC, and is generally labeled the ISM
band. A few years ago Apple and several other large corporations requested that the
FCC allow the development of wireless networks within this frequency range. What
we have today is a protocol and system that allows for unlicensed use of radios
within a prescribed power level. The ISM band is populated by Industrial, Scientific
and Medical devices that are all low power devices, but can interfere with each other.

What is Server Set ID (SSID)?

SSID is a configurable identification that allows clients to communicate to the
appropriate base station. With proper configuration, only clients that are configured
with the same SSID can communicate with base stations having the same SSID. SSID
from a security point of view acts as a simple single shared password between base
stations and clients.

What is an ESSID?

ESSID stands for Extended Service Set Identifier and identifies the wireless LAN. The
ESSID of the mobile device must match the ESSID of the AP to communicate with the
AP. The ESSID is a 32-character maximum string and is case-sensitive.
