Data exchange
Transmission of data between communication partners.
Device Name
The

name of a device. This name can be queried by other
Bluetooth

devices via a radio link.
DHCP (Dynamic Host Configuration Protocol)
This protocol permits automatic configuration of the network for a computer, and
also assigns addresses or sets parameters centrally. The DHCP server uses a fixed
IP address pool for automatically assigning random, temporary IP addresses to
networked computers (Clients), thus saving considerable configuration work in
large networks. The client also obtains other information, such as the gateway
address (router) and the IP address of the name server (
DNS
).
Diagnostics
Diagnostic information provides information on the system status, particularly on
disturbances or error conditions.
E
ETHERNET
Specifies a Local Area Network (
LAN
), which was developed by Xerox, Intel and
DEC in the 70's. The bus access process takes place according to the CSMA/CD
method.
F
Frequency Hopping Spread Spectrum (FHSS)
Generally: The frequency hopping process known as “Frequency Hopping Spread
Spectrum” (FHSS) involves the division of a frequency range into sub-ranges,
between which the data transmission then alternates. This improves co-existence
with other networks and provides additional tapping protection and strength
against narrow band disturbing influences.
Bluetooth
®
context: subdivision of the wireless channel into 79 subchannels. Each
time, after transmission of a packet, the current sub-channel is changed. This may
occur up to 1600 times per second.
G
Gateway
Device for connecting two different networks, performs the translation between
differing protocols..
