Glossary of Terms & Abbreviations
Term
Stands For....
Meaning
802.11
802.11 Standard
An IEEE LAN standard for wireless Ethernet replacement
technology in the ISM band. Runs at up to 10 Mbps.
ACC
Access Channel or
Access Code Channel
AKA, Paging Channel. The signal path that tells a mobile to
prepare for an incoming call.
ACK
Acknowledge
Positive message sent by a protocol to acknowledge reception
of a transmitted packet
AP
Access Point
Wireless LAN transceiver that acts as a center point of an all-
wireless network or as a connection point between wireless and
wired networks.
ARP
Address Resolution Protocol
The function of the ARP is to match higher-level network IP
addresses with the physical hardware address of a piece of
equipment.
ASYNCH
Asynchronous
Not occurring at regular intervals, as in data piped over a
network
ATM
Asynchronous Transfer Mode
Transporting a broad range of user data at irregular intervals
over network facilities
BB
Broadband
RF system with constant data rate of 1.5 Mbps or higher.
BCC
Broadcast Code (or Control)
Channel
A channel of data transmitted by one entity and received by
many devices.
BS
Base Station
Network Access equipment and software that transmits and
receives, as well as processes, voice or data calls from mobile
units to network connections. A Ripwave Base Station consists
of the Base Transceiver Station (BTS) and the Radio
Frequency Subsystem (RFS), or antenna, plus a Global
Positioning System (GPS) antenna for timing.
BTS
Base Transceiver Station
The Ripwave BTS is a two-shelf rack that holds the RF
modules and digital circuit cards that interpret radio signals
into computer language and sends messages to and from the
local or wide area network. It functions between the RFS and
the EMS to handle the signaling.
BW
Bandwidth
Frequency spectrum usable for data transfers. It describes the
maximum data rate that a signal can attain on the medium
without encountering significant loss of power. Usually
expressed in bits per second (digital) or Hertz (analog).
BYTE
Byte 8
bits
CAM
Configuration & Alarm Manager
An EMS functionality that is handled through a Graphical User
Interface for purposes of configuring elements in the system
and handling other OAM requirements.
CC
1
Communications Controller or
2
Cross-check
1
A type of circuit card that resides in the Digital shelf of the
Ripwave BTS. It handles all interfaces between BTS and
network.
2
An EMS functionality that allows the system to
perform an automated sanity check of the datafill.
