Glossary
Windows CE Application Manager. The desktop Windows CE Services component that provides a
CeAppMgr
desktop-to-device application management tool. It is responsible for adding and removing applications
on the Windows CE device and for deleting the application files from the desktop computer.
CeAppMgr is included with every installation of Windows CE Services.
A radio device that uses the services of an access point to communicate wirelessly with other devices
Client
on a local area network.
Carrier sense multiple access. A wireless LAN media access method specified by the IEEE 802.11
CSMA
specification.
A method of checking for errors in a received packet.
Cyclic Redundancy
Check (CRC)
D
The range of data transmission rates supported by a device. Data rates are measured in megabits per
Data Rates
second (Mbps).
A ratio of decibels to an isotropic antenna that is commonly used to measure antenna gain. The greater
dBi
the dBi value, the higher the gain and the more acute the angle of coverage.
Dynamic Host Configuration Protocol. A protocol available with many operating systems that
DHCP
automatically issues IP addresses within a specified range to devices on the network. The device retains
the assigned address for a specific administrator-defined period.
A type of low-gain (2.2-dBi) antenna consisting of two (often internal) elements.
Dipole
A network server that translates text names to IP addresses.
Domain Name
Server
Provides names for computers using alphanumeric characters instead of numbers like IP addresses use.
Domain Name
System (DNS) Maintains a database of the host alphanumeric names and their corresponding IP addresses.
Direct-sequence spread spectrum. A type of spread spectrum radio transmission that spreads its signal
DSSS
continuously over a wide frequency band.
Packets that were received twice because an acknowledgement got lost and the sender retransmitted the
Duplicate Packets
packet.
E
Extensible Authentication Protocol. EAP is the protocol for the optional IEEE 802.1X wireless LAN
EAP
security feature. An access point that supports 802.1X and EAP acts as the interface between a wireless
client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server,
to which the access point communicates over the wired network.
The most widely used wired local area network. Ethernet uses carrier sense multiple access (CSMA)
Ethernet
to allow computers to share a network and operates at 10, 100, or 1000 megabits per second (Mbps),
depending on the physical layer used.
