Network Information
DataTAC Network Technology for the ARDIS Network
The DataTAC infrastructure has become an international data communications
standard, offering fast data transmission rates with accurate, highly reliable message
delivery. DataTAC networks are deployed around the world from North America
to Europe to Asia-Pacific.
Using an advanced Radio Data Link Access Procedure (RD-LAP) radio channel
protocol, DataTAC systems provide transmission rates up to 19.2 Kb per second
and 9.6 Kb per second depending on the country. Those rates mean fewer delays
and faster response times for the mobile user. For network operators, they mean
greater capacity to accommodate more customers, while minimizing the required
investment in network infrastructure.
DataTAC’s error detection and correction schemes provide increased message
accuracy, fewer message retries and enhanced network throughput. With DataTAC
technology, the state of the entire network is constantly monitored and safety
mechanisms including system alarms, remote diagnostics and redundant backup
links ensure network reliability and availability.
The key components of the network infrastructure include the Network Management
Center (NMC), Area Communications Controller (ACC) and base site equipment.
The NMC is an advanced client-server based management tool which provides all
network administration, operation and maintenance functions. It acts as the central
point of control in the DataTAC system.
The ACC consists of the Radio Network Gateway (RNG), Radio Network Controller
(RNC), and Communications Hub. The ACC is primarily responsible for all message
switching and routing functions, as well as providing the key communication link
between host computers and remote base stations. Connectivity between the host
computer and the infrastructure is established using industry standard X.25 or TCP/
IP host link protocols. The ACC maintains all customer-specific information for
each device on the system and allows users within a given geographical area to
connect to host application services. It manages user device system usage/traffic
information for accounting/billing purposes and detailed analysis of usage patterns.
DataTAC Data System Station (DSS) base site equipment is located at various
remote sites in the operational area of coverage and provides the RF link between
the DataTAC infrastructure and end user devices. They convert the host data
messages into the RD-LAP radio channel protocol for transmission to the user
devices and reverse the process on the return connection. They also allow device
roaming between base site coverage areas in a seamless manner completely
transparent to the end user.

Network Information (cont.)
Mobitex Network Technology for the RAM Network
The Mobitex wireless network technology, developed by Eritel in 1984 for Swedish
Telecom, has become an international data communication standard. Now managed
by the Mobitex Operators Association (MOA), which controls the specifications
for this open standard, Mobitex is a secure, reliable, wireless packet switching
network specifically designed for wide-area wireless data communications.
Mobitex networks are deployed on every continent in the world (except Antarctica).
Mobitex is presently available* in Australia, Belgium, Canada, Chile, Finland,
France, Germany, Korea, the Netherlands, Nigeria, Norway, Poland, Singapore,
Sweden, the United Kingdom, and the United States.
Mobitex provides highly reliable, two-way digital data transmission. The network
provides error detection and correction to ensure the integrity of the data being sent
and received, and includes transmission acknowledgment.
The Mobitex network has a hierarchical (or pyramid) network structure. Messages
are routed from sender to receiver along the most direct path possible. Each Mobitex
radio modem is assigned a unique Mobitex Access Number (MAN), and the network
remains constantly aware of the mobile’s location while it is within network coverage.
Each radio cell is served by an intelligent base station. Because intelligence is
distributed throughout the network, data is only forwarded to the lowest network
node common to the sender and the receiver. The base station is thus able to
handle all local traffic in the cell.
The network constantly monitors the location of the mobile users. As a mobile
moves from one area of coverage to another, base stations track its signals, sending
updated mobile location and status information to the network. If the network goes
down at any point in transmission, the message is held until network service is
restored. If the mobile receiver moves outside the coverage area, the base station
holds on to data until coverage is reestablished, thus preventing loss of data and
increasing reliability of transmission.
Mobitex uses a packet switching technique to provide the greatest flexibility in
data transmission. Mobitex packets include information about the origin, destination,
size, type, and sequence of data to be sent, enabling packets to be transmitted
individually, in any order, as traffic permits. Individual packets may travel along
different routes, in any order, without interfering with other packets sent over the
same frequency by different users. At the receiving end, all packets are accounted
for, and reassembled into the original message. Setup time is eliminated and network
connection is instantaneous. As a result, packet-switching makes far more efficient
use of channel capacity, typically allowing 10 to 50 times more users over a radio
channel than a circuit switched network.

Network Information (cont.)
Cellular Digital Packet Data (CDPD) Network Technology
The Cellular Digital Packet Data (CDPD) network is a two-way wireless data
communication system. This system uses cellular telephone channels to transfer
data seamlessly from a mobile end system to a fixed end system. CDPD operates
within the already existing cellular telephone infrastructure utilizing the idle time
that exists on cellular voice channels to send small packets of data, called datagrams,
to a designated receiver. Researchers estimate that over 30% of a cellular channel’s
airtime is idle, even during heavy traffic.
The CDPD system sends signals down the various cellular channels to locate an
open channel. This process is called “sniffing”. Once the CDPD system has located
an open channel, the modem begins to send datagrams over that channel to the
designated end user. In order that this process does not interfere with the cellular
phone transmissions, the CDPD system has regulated channel “hops” to ensure
that CDPD usage will not block a cellular voice channel for an extended period of
time. Also, if a voice channel is activated, the CDPD system detects this voice
message and automatically “hops” to the next available idle channel. This process
is quite complex. However, the user need not be aware of this process. The CDPD
system manages the routing of the individual data packets to the proper destination.
On a basic level, the CDPD network operates like any other computer network
with the exception that the CDPD mobile end system is free to roam wirelessly and
conduct network operation from other locations using the network of cellular carriers.
The CDPD network is made up of a series of cellular networks which are operated
by various cellular carriers. These cellular carriers provide the user with network
management as well as application services. To increase user security, carriers use
forward error correction, authentication, and encryption. The cellular carrier is
responsible for all accounting services for the CDPD service. The user selects the
CDPD carrier service with which to operate by registering with an individual carrier.
Generally, an area will have two cellular carriers that provide CDPD service. The
user may sign up with either of the two carriers.
CDPD technology provides many benefits to the user including the following:
CDPD is cost-effective. By compressing data before sending it over thecellular
channels, CDPD cuts down the amount of data to be transmitted, and thus, reduces
the cost of cellular usage. Another cost-reducing advantage of CDPD is that the
user is only charged for the data transmitted, not for the airtime used. And by using
the existing cellular infrastructure currently in place for the voice network, CDPD
has few start-up expenditures which further reduces cost to the user. CDPD is fast.
At 19,200 bps, it is one of the fastest wide-area data networks. CDPD is mobile. It
allows free travel between cell cites. The CDPD system automatically tracks the
user’s position and allows the user to maintain communication between cell cites.
CDPD is reliable. It utilizes error correction applications for dependable data
delivery.
