Product & Service Directories
- Wireless
Network Infrastructure Products -
Ericsson, Lucent, Motorola, Nortel Networks, Siemens, and
Qualcomm are among the major suppliers of wireless network infrastructure products. Their
products are used for installing private or public shared radio networks operated by the
end user organizations (e.g. public safety agencies), telecommunications carriers and
network service providers.
Typically, network service providers and public
wireless network operators evaluate network infrastructure options and products in a more
comprehensive manner. MOBILEINFO pages may not serve their complete information needs.
Our web site is primarily aimed at mobile computing and RF
network professionals in enduser organizations who normally evaluate which network
infrastructure may be suitable for their mobile applications. Therefore, we shall provide
only a limited amount of information on these products.
Ericsson’s Private Mobile Data Networks – EDACS
Network and Gateway – an Integrated Voice and Data Gateway
Ericsson offers products for building integrated voice and data networks for mobile
users of an enterprise. Several public safety agencies have employed EDACS network and
gateway for police, fire control, ambulance dispatch applications. Many organizations have
implemented both voice and data, some organizations have decided to implemented voice
only. Remember, voice is given higher priority over data in most networks, including
EDACS. Please go to http://www.ericsson.com/US/prs/prs100.html
for more information.
Ericsson Mobitex Network – This
legacy wireless network
infrastructure is aimed primarily at wireless data network service providers who want to
provide shared public wireless packet data services to enduser organizations.
Cingular (formerly Bell South
Wireless Data) provides this type of service in USA – there are Mobitex
networks in over 15 countries. Several components comprise a Mobitex network – base
stations controllers, Message Exchange Switch (MOX), antennas, radios and modems. For more
information on the architecture of Mobitex, please read chapter 8 of Mobile Computing
handbook. For current information on Mobitex components, click on Mobitex page of
Ericsson’s web site – http://www.ericsson.se/wireless/products/mobsys/mobitex/mobitex.shtml
BRU34 and 39 are two different models of Mobitex base
stations. BR39 Base Radio Unit is current model. Major features of BRU3901 are
:
- Outdoor/indoor installation, small size (13"x17"x7""’), low
weight (40 lb.), approximately 5 KM coverage
- Simplicity of installation, with up to 3 years of operation without on-site maintenance
- 3 watt output
- Frequency range Rx 896-902 MHz, Tx 935-941 MHz

M2000 Mobidem
M2000 is a small low power radio modem that can be built into PC or other
equipment. It has no power source of its own. It does not have its own antenna, which must
be designed specifically for the host equipment. It has rated data transfer rates of 1200
to 9600 bps. It supports Mobitex MACS, AT and X.28 protocols. There are three versions of
M2000:
- M2050 425-460 MHz UK
- M2060 410-432 MHz Rest of Europe
- M2090 896-941 MHz USA and Canada
Major applications of M2000 are in telemetry, vending
machines, kiosks, etc.
Other Mobitex modems - M2100, M3090 and M4000 series
M2100 is a type III PC card modem.
Research in Motion (a wireless manufacturer in Waterloo, Ontario, Canada) supplies a
Mobitex modem as well. Click on www.rim.net for more
info.
Ericsson C710/M Radio Modem
- It is a radio and data modem combined into a single unit.
- It is designed to run on Mobitex network.
- It can transmit data at 8000 bps.
- Uses GMSK modulation technique.
Ericsson’s Other Wireless Network Products
Ericsson offers infrastructure products to carriers and network service providers who
want to build public shared networks based on GSM, TDMA, PDC, TACS, and WCDMA
technologies. For more information, click here.
Motorola Radio Network Product
Line
Motorola supplies hardware and software for both conventional and trunking radio
networks. These products serve a single site as well as wide area networks. Wide area
solutions are based on simulcast as well as SmartZone™ technologies.
Simulcast
broadcasts identical information on the same carrier frequency from
multiple, geographically separated sites. Therefore, it is used to extend a system’s
coverage beyond a single site. It is analogous to cell reuse concept implemented in
cellular networks. SmartZone connects individual sites to form one large, seamless
radio network. Motorola M6809 is a trunking central controller that coordinates between
sites.
Besides conventional and trunking radio networks, Motorola also supplies iDEN and
DataTac private networks.

for general information on Motorola networks and click on specific networks for details
about that product.
-
Conventional radio networks – from basic radio to radio to wide area coverage
-
Trunking radio networks – more advanced management, priority schemes and more
efficient frequency usage
-
IDEN networks – public network technology for radio to radio, telephony, text
messaging and data transmission
-
DataTac Private networks

Nortel also manufacturers, sells and supports IS-41 compatible CDMA network solutions
for PCS networks. With ‘DualMode’ (e.g. CDPD and voice) microcell architecture,
Nortel products can increase overall capacity of the network and reduce coverage problems,
especially at traffic intersections, tunnels and other locations where other base stations
located further away may not be able to penetrate. Nortel product line offers conventional
AMPS, TDMA and CDPD from the same radio and antenna platform.
