This chapter introduces the Mobitex system, the M3090 radio modem and the
mode of communication between a radio modem and its host equipment.
 7KH0RELWH[1HWZRUN
The M3090 radio modem operates through a Mobitex network, a radio network
for data communication. The network consists, mainly, of exchanges, radio base
stations, fixed terminals and mobile terminals.

 5DGLREDVHVWDWLRQVDQG([FKDQJHV
Radio base stations direct data to and from the fixed and mobile terminals in
their coverage area. If a radio base station receives data addressed to a mobile
or a fixed terminal outside its coverage area, the radio base station transfers the
data to the exchange to which it is connected. The exchange, in turn, transfers
the data to the radio base station that is in contact with the addressed terminal.
 03$.V
Throughout the Mobitex network, data is transmitted and received in the form
of data packets, called MPAKs. Each MPAK includes addressee, sender and
user data (text and binary data), as well as certain control data.
An MPAK can contain a maximum of 512 bytes of user data.

The transmitter is turned on when the radio modem:
• Is about to become active in the network.
• Transmits data, i.e. MPAKs, to the radio base station.
• Acknowledges received MPAKs.
• Changes radio base stations; it then has to inform the network of the change,
this is called Roaming.
• Changes its operation mode, from power saving mode to express mode or
vice versa.
5HFHLYHU
Besides receiving MPAKs addressed to the host, the radio modem frequently
receives control signals from the network. These control signals are used to
select the radio base station with the strongest radio signal.

Using the Mobitex Asynchronous Communication Protocol (MASC), the micro
controller handles communication between the host and the Mobitex network.
The controller consists of a CPU, internal software which handles the MASC
protocol, and a radio protocol for communication with the network. For further
information about the MASC protocol, see the MASC Programmers Manual.

Power is supplied through the system connector. The required voltage is 6-9 V
DC (nominally 7.5 V).
3RZHU2SHUDWLQJ0RGHV
When the radio modem is powered, it operates in one of the following three
modes:
• sleep
• receiving
• transmitting
Unless communication within the Mobitex network is very intense, the radio
modem spends most of its time in the sleep mode. In this mode, the modem
waits for host requests and the air interface is inactive. The sleep mode is
entered whenever the radio modem is reset or powered on.
The radio modem enters receiving mode when:
• the power saving protocol says it is time to monitor the radio link (power
saving mode)
• the host requests that the radio link be constantly monitored (express mode)
• data from the network is expected
• the host requests access to the network.
When data needs to be transmitted, the radio modem enters transmitting mode.
The time spent in this mode is minimized in order to reduce power
consumption.

The host equipment must provide an external antenna. The antenna is connected
to the radio modem's antenna connector of the SMT type (from M/A Com, see

 $ERXW$QWHQQDV
This chapter contains some antenna-technology basics. It is intended to help
integrators with little previous experience to select an antenna for the host with
which the M3090 radio modem is to be integrated.
If a non-standard antenna has to be designed, please consult an antenna
specialist.
 7KH)XQFWLRQVRIDQ$QWHQQD
An antenna has two functions:
• to emit radio waves (transmission)
• to pick up radio waves (reception).
The antenna does this more or less efficiently, depending on:
• the type of antenna
• the placement of the antenna
• the environment in which the antenna is used.
 +DOIZDYHDQG4XDUWHUZDYH$QWHQQDV
Two types of antennas are commonly used for mobile radio terminals:
• half-wave antennas
• quarter-wave antennas.
Both are omni-directional antennas, that is, they radiate energy in all directions.
However, a half-wave antenna is less sensitive to external influences
(movements in its vicinity etc.) than a quarter-wave antenna.

$QWHQQD/HQJWKV
The following lengths are typical for half-wave and quarter-wave antennas in
the frequency range that the M3090 radio modem uses. The lengths shown can
vary somewhat, depending on the material that surrounds the core of the
antenna.
6KRUWHQHG$QWHQQDV
A shortened antenna is even shorter than a quarter-wave antenna. It can be
designed to have characteristics that are nearly as good as those of a full-length
antenna.
 $QWHQQD&RQFHSWV
The following sections present some fundamental concepts with regard to
antennas.
 $QWHQQD*URXQG3ODQH
An antenna ground plane is an area under the antenna that is connected to
ground and horizontal, flat and sufficiently wide. An antenna with a ground
plane will function more efficiently.
It is especially important that quarter-wave antennas have a ground plane.
 3RODUL]DWLRQ
Radio waves radiate parallel to the antenna. The best reception is achieved when
the receiving antenna is parallel to the transmitting antenna.
The antennas of Mobitex radio base stations are vertical, which means that the
radio waves are vertically polarized.

 $QWHQQD*DLQ
Antenna gain is defined as the ratio between the antenna’s radiant intensity and
that of a reference antenna which experiences no loss, but has the same power
input.
Antenna gain is usually expressed in dBi, the i indicating that the calculated
radiation from an isotropic antenna has been used as a reference. The isotropic
antenna has the same radiant intensity in all directions, that is, the radiation
pattern is spherical.
1RWH In data sheets, an antenna’s maximum gain is often expressed in
dBd without any reference to direction. The (second) d in dBd
indicates that the calculated radiation from a single half-wave
dipole antenna is used as a reference.
The relationship between dBd and dBi is described in )LJXUH.
 (QYLURQPHQWDO,QIOXHQFHV
The antenna must have sufficiently effective radiation for the radio terminal to
be able to communicate with a radio base station. The maximum range might
be up to 15 or 20 kilometres depending on:
• what frequency range the Mobitex network uses (the higher the frequency,
the shorter the maximum distance);
• whether the terminal is situated in a built-up area or in open country.
In an urban area, attenuation caused by buildings, walls and other obstacles has
to be considered. Too large or too many obstacles around the antenna might
mean that the radio terminal cannot establish a contact with the radio base
station. In such a case, the antenna is said to be in a radio shadow.

An antenna cable is required to connect an antenna to the M3090 modem’s
antenna connector, that is, a detached antenna is used. A detached antenna
should consist of three parts: the antenna rod, an impedance matching network
and a coaxial cable with a connector.
A detached antenna may often be more effective than other types, especially
when the radio terminal is used in a vehicle.
 $QWHQQD5RG
A half-wave dipole antenna should preferably be used. It should be low-weight
and as short as possible, while still complying with the antenna specifications.
Antenna specifications are found in FKDSWHU³7HFKQLFDO'DWD´.
 $QWHQQD&DEOH
A cable with connectors at each end is required to connect a detached antenna
to the radio modem. Use a low-loss cable with high-quality connectors to avoid
loss of signal power between the antenna and the modem. Both the cable and
the connectors must have an impedance equal to that of the antenna connector
of the radio modem, that is, 50 .
The antenna cable should be flexible to allow easy fitting of the antenna in a
vertical position.
Poor contact between, or mismatching of, the connectors may cause a partial
reflection of the signal from the radio modem. The ratio between the modem’s
output power and the power reflected from the antenna is defined as the Voltage
to Standing Wave Ratio (VSWR) and is calculated using the formula shown in

M3090 Integrator’s Manual, Doc.no: 19 817-KRD 102 303 Uen, Rev A
To get an effective communication, a VSWR of 2 or less is recommended for
the antenna, see FKDSWHU³7HFKQLFDO'DWD´.
 $QWHQQD6XSSOLHUV
The integrator can use an antenna supplied by a third party or design one that
complies with the antenna specifications in FKDSWHU³7HFKQLFDO'DWD´.
The following antennas perform well and have been used during certification:
1RWH The above antennas fulfil FCC requirements for RF power
emission into nearby human bodies (SAR) with a good margin
also in worst-case situations. However, it is recommended that
the antenna is installed so that there, in normal use, is a distance
of at least 5 cm (2 inch) to human bodies.
If any other than the above antennas is used, the integrator is recommended to
verify that applicable emissions standards are complied with.

Integrator’s Kit (Product No. KRY 901 46). The kit contains:
• The MobiOne configuration software (Windows 95/NT compatible) for the
setting of a Mobitex Access Number, country code(s) etc. before the modem
is used in a Mobitex network.
• MASC-Driver, with source code.

Place the radio modem so that it is protected from pollution, vibrations and
shock. Avoid placing the modem close to any circuit that is likely to cause
interference. Secure the modem correctly to prevent it from falling out when
transporting or moving the host equipment.
The antenna should preferably be fitted so that it is always vertical, regardless
of the host equipment’s position.
Make sure that the radio modem’s antenna and system connectors can be
accessed when the modem is fixed in the host equipment.

Normally, no special measures are needed to cool M3090 radio modems.
However, if ambient temperature exceeds +65 C (see &KDSWHU.), cooling
will be required, otherwise the modem may over-heat and lose contact with the
network.
The heat dissipation of an M3090 radio modem varies depending on the volume
of data being transmitted. In normal use, when the modem transmits less than
1% of the time, the power consumption is less than 300 mW.
 *URXQGLQJ
The M3090 radio modem card does not need to be grounded beyond what is
provided through the system connector.
However, it is recommended that the antenna connector be grounded, by
grounding the fixing screws. This will:
• improve the gain of the antenna;
• make the radio modem less sensitive to electrostatic discharge (ESD).

M3090 radio modems are sensitive to electrostatic discharge. Use normal
precautions to prevent ESD.

M3090 radio modems fulfil the shielding requirements set by the regulatory
approval authorities in the USA and Canada. Therefore, additional shielding of
the modem is normally not necessary.

Any two-way communication radio, such as the M3090 radio modem, must be
type-approved by the appropriate authorities before it can be sold and used in a
country. Most countries have their own national bodies for type-approvals, but
a number of European Community member countries share a common
authority.
These authorities grant type-approvals to radios that have been successfully
tested by a certified radio test laboratory. The tests performed show if the radio
complies with the standards specified by the type-approval authorities.
