Cable and Connector Loss
During wireless design and deployment, it is important to factor in the cable and connector loss.
Cable and connector loss will reduce the output power and receiver sensitivity of the radio at
connector end. The longer the cable length is, the more the cable loss. Cable loss should be
subtracted from the total output power during distance calculation. For example, if the cable and
connector loss is 3dBm and the output power is 20dBm; the output power at the cable end is only
17dBm.
Client
Client means a network device or utility that receives service from host or server. A client device
means end user device such as wireless cards or wireless CPE.
CPE Devices
CPE stands for Customer Premises Equipment. A CPE is a device installed on the end user's side to
receive network services. For example, on an ADSL network, the ADSL modem/router on the
subscriber's home is the CPE device. Wireless CPE means a complete Wireless (usually an AP with
built-in Antenna) that receives wireless broadband access from the WISP. The opposite of CPE is
CO.
CTS
Clear To Send. A signal sent by a device to indicate that it is ready to receive data.
DDNS
Dynamic Domain Name System. An algorithm that allows the use of dynamic IP address for hosting
Internet Server. A DDNS service provides each user account with a domain name. A router with
DDNS capability has a built-in DDNS client that updates the IP address information to DDNS service
provider whenever there is a change. Therefore, users can build website or other Internet servers
even if they don't have fixed IP connection.
