Description 

IEEE 802.16 

IEEE 802.16 is a wireless networking standard adopted in December, 2001. 

BS 

BS is the abbreviation of Base Station, a basic component in WiMAX 

infrastructure. 

SS 

SS is the abbreviation of Subscriber Station, a user-client in WiMAX 

infrastructure. 

CPE 

CPE is the abbreviation of Customer-Premises Equipment, acting as a client. 

DHCP 、  DHCP 

Client 、 DHCP 

Server 

DHCP, Dynamic Host Configuration Protocol . An Ethernet protocol specifying 

how a centralized DHCP server can assign network configuration information to 

multiple DHCP clients. The assigned information includes IP addresses, DNS 

addresses, and gateway (router) addresses. 

IP Address and 

Network Mask 

IP Address is a four-byte number uniquely defining each host on the Internet, 

usually written in dotted-decimal notation with periods separating the bytes (for 

example, 134.177.244.57). Ranges of addresses are assigned by Internet, an 

organization formed for this purpose.   

Combined with the IP address, the IP Subnet Mask allows a device to know 

which other addresses are local to it, and which must be reached through a 

gateway or router. 

LAN&WAN 

LAN (Local Area Network): A communications network serving users within a 

limited area, such as one floor of a building. 

WAN: A long distance link used to extend or connect remotely located local area 

networks. The Internet is a large WAN. 

Router 

A device that forwards data between networks. An IP router forwards data based 

on IP source and destination addresses. 

NetBIOS 

Network Basic Input Output System. An application programming interface 

(API) for sharing services and information on local-area networks (LANs). 

Provides for communication between stations of a network where each station is 

given a name. These names are alphanumeric names, 16 characters in length. 

Encryption 

To secure the communication between the wireless device and other devices, 

encryption is implemented to protect secret against attack.   

MAC   

The Media Access Control address is a unique 48-bit hardware address assigned 

to every network interface card. 

Ping 

Using “ping” command aims at checking the communication between your
