AES – Advanced Encryption Standard
APL – Advanced Protection Logic
dBM – decibels milliwatt (power ratio)
CDMA - Code Division Multiple Access is a channel access method used by various radio communication
technologies that allows many users to occupy the same time and frequency allocations in a given band/space.
DHCP – Dynamic Host Configuration Protocol, which provides a mechanism for allocating IP addresses
dynamically so that addresses can be reused when hosts no longer need them.
DNS – Domain Name System, which is a distributed hierarchical naming system used to resolve domain names
(e.g., www.yahoo.com) into numerical IP addresses (e.g., 204.17.25.1).
Ec/Io – Signal to noise ratio of the current channel for CDMA (Measured in dB).
Eb/No – Signal to noise ratio of the current channel for UTMS (3G) (Measured in dB).
ESN – Electronic Serial Number (32 bit number that identifies a CDMA device)
Gateway IP Address – A gateway (sometimes called a router) is a computer and/or software used to connect
two or more networks (including incompatible networks) and translates information from one network to the
other. The Gateway IP address is the IP address for the gateway.
GPRS – General Packet Radio Service
GSM – Global System for Mobile communications, which is an international standard for digital mobile phone
systems used for cellular communication.
HSDPA – High-Speed Downlink Packet Access
HSPA – High-Speed Packet Access
ICCID – Integrated Circuit Card Identifier (SIM Card serial number)
IMEI – International Mobile Equipment Identity number
IP – Internet Protocol
IP Address – A unique number consisting of four parts separated by periods, sometimes called a "dotted quad.,"
for example: 204.17.29.11, assigned to every computer/workstation connected to the Internet. IP numbers can
be "static" (assigned and unchanging) or "dynamic," assigned via DHCP at each and every startup.
ISP – Internet Service Provider
KBPS – Kilobits per second
MAC ID – Media Access Code; located on the module label.
MEID – Mobile Equipment Identifier (56 bit number that identifies a CDMA device)
NIC – Network Interface Card
RSCP – Received Signal Code Power (Ratio of RSSI and Ec/No)
RSSI – Received Signal Strength Indication
SCID – SIM Card ID
Subnet Mask – A Subnet is a portion of a network that shares a network address with other portions of the
network, and is distinguished by a subnet number. The Subnet Mask is a 32-bit address mask used in IP to
indicate the bits of an IP address that are being used for the subnet address.
UMTS – Universal Mobile Telecommunications Service
WAC – Wi-Fi Accessory Configuration
WEP – Wired Equivalent Privacy
WPA – Wi-Fi Protected Access
WPS – Wi-Fi Protected Setup
