P-660HW-Tx v2 Series Support Notes
WLAN NICs often include an internal antenna which may provide sufficient
reception.
7. Why 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.
8. 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.
9. 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.
Security FAQ
1. How do I secure the data across the P-660HW-Tx v2 Access Point's
radio link?
To secure the date across the P-660HW-Tx v2 Access Point's radio link, we
could select any one of the security mode:
Static WEP (Wired Equivalency Protocol )
WPA-PSK
WPA (Wifi-Protected Access)
WPA2-PSK
WPA2
2. What is WEP?
Wired Equivalent Privacy. WEP is a security mechanism defined within the
802.11 standard and designed to make the security of the wireless medium
equal to that of a cable (wire). WEP data encryption was designed to prevent
access to the network by "intruders" and to prevent the capture of wireless
LAN traffic through eavesdropping. WEP allows the administrator to define a
set of respective "Keys" for each wireless network user based on a "Key
