4.0 GPRS Background

General Packet Radio Services (GPRS) is a packet based wireless communication service that can deliver
variable data rates as a function of assigned timeslots and maintain continuous connection to the Internet
for mobile subscribers on Global System for Mobile (GSM) Network worldwide. Since GPRS is based on
GSM communication, it can be single, dual or triple band depending on the area of the service, it will
complement existing services such as circuit switched cellular phone connections and the Short Message
Service (SMS).
In general, GPRS packet-based service should cost users less than circuit-switched services, since their
communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated
only to one user at a time. Once GPRS becomes available, mobile users of a virtual private network (VPN)
will be able to access their private networks continuously rather than through a dial-up connection. GPRS
will also complement Bluetooth, a standard for replacing wired connections between devices with wireless
radio connections. In addition to the Internet Protocol (IP), GPRS supports X.25, a packet-based protocol
that is used mainly in Europe and Asia Pacific. GPRS is an evolutionary step toward Enhanced Data GSM
Environment (EDGE) and Universal Mobile Telephone Service (UMTS).

The key benefit with GPRS is the ability to sustain a permanent data connection allowing a free flow of
information for the mobile user. The data through put in GPRS will be significantly higher due to the
ability of GPRS mobile terminals to transmit and receive more information than standard GSM terminals.

The GSM communication system, in general, is standardized to operate in multiple bands, primarily, the
900 MHz band which is assigned PGSM, EGSM, RGSM for short, 1800 MHz band which is assigned DCS
and the 1900 MHz band which is assigned PCS. Both the GSM and DCS band are used globally for mobile
voice communication. The PCS 1900 is used in North, Central and South America.

• Enabler-G Model No. GSM0102 900/1800 MHz

• Enabler-G Model No. GSM0103 900/1900 MHz

Although the GSM digital voice standard has existed for well over a decade, it wasn’t until recently that the
demand for wireless data capability has increased. GPRS is a protocol within the GSM standard which was
developed to address the need for data only transmission. Although the GSM voice protocol does support
data transmission, it is limited in data rate due to overhead within the voice protocol. What the GRPS
allows is a faster data rate that is adaptive as well as being packet based.

6.0 Electrical Characteristics

6.1 Input Voltage and Power

The modem operates from an input voltage range of 3.15 Vdc to 4.50 Vdc. Input voltage may be directly
applied from a 3.6V Li-Ion or Nickel Metal Hydride battery. The digital input and output signals are 3.3
Vdc tolerant.

6.2 Power Consumption

The modem has four power consumption modes:

Transmit @ 28 dBm < 1000 mA < 3300 mW

The modem has three hardware sections. Each is powered separately. These hardware sections are (a) the
digital circuitry, (b) the RF receiver circuitry, and (c) the RF transmitter circuitry. The following chart
describes which sections are powered on during each power consumption mode.

Mode Digital Circuitry

Off/ Standby Off Off Off
Sleep Low power most of time Off most of time Off
Receive On On Off most of time
Transmit On On On

Modem Off/ Standby Mode

In the Modem Off mode, a FET switch inside the modem is turned off. All power within the modem is
removed. A WAKE command or power cycle is required to come back to functional status.
allows the unit to be put in deep sleep. A WAKE command or power cycle is required to return to

functional status

Sleep Mode

Sleep mode is defined by the GPRS specification. If Sleep mode is enabled (user option), the modem will
enter Sleep mode after a user-specified period of time if there is no IP data traffic across the serial port. The
modem then disables its RF receiver, disables its RF transmitter, and places the digital circuitry in a low
power state for the sleep timeout period negotiated with the GPRS network (typically 60-90 seconds). The
modem will enable its RF receiver and digital circuitry after the specified sleep timeout and check if any
new message is waiting from the GPRS network. If no new message is available, the modem disables its
circuitry and returns to sleep for the specified timeout period before waking up again. If a new message is
available from the GPRS network, the modem remains in Receive mode and reads the message. After
receiving a message, the modem will remain in Receive mode until the next period of serial port inactivity
occurs. If the host computer sends a message to the serial port, the modem immediately exits Sleep mode,
returns to Transmit mode, and transmits the message to the GPRS network.

Receive Mode

The unit is in Receive mode anytime it is trying to register or maintaining registration but has no data to
transmit. During this mode, the transmit circuit is turned off, but the receive circuitry is turned on. The
GPRS protocol requires occasional transmit bursts to maintain registration even if no data traffic is
occurring.

Transmit Mode

During Transmit mode, the modem is fully operational. The transmitter and receiver are both on since the
unit is a full duplex modem. The transmit power required varies based on the received signal power.

Mode Current Power @ 3.3 Vdc Input

Transmit power level varies based upon the proximity of the modem to the cell site, RSSI measured by the
modem, and maximum power level allowed by the cell site.

7.0 Radio Performance

The following table shows the standard channel allocation for the EGSM 900 and PCS 1900 band. The EGSM
transmitter transmits at exactly 45 MHz below the receive frequency. The PCS transmitter transmit at exactly 80
MHz below the its received frequency.

The primary advantage of the GSM standard is that, regardless of the band of operation, they all share the same
technical features. This specification applies to the GSM voice, voice & data, and data only (GPRS) transmission.
With TDMA, one GSM RF channel can support up to 8 mobile users simultaneously. Each user is allowed to
transmit once every frame period for a 1 timeslot duration. Because of the TDMA scheme, timing accuracy in the
software and hardware implementation is very critical. The Enabler has the following common specifications.

Mobile Station Transmit Frequency

= 890 MHz + 0.2(n)

Mobile Station Transmit Frequency

= 890 MHz + 0.2(n-1024)

Mobile Station Transmit Frequency

= 1850.2MHz + 0.2(n-512)

Mobile Station Receive Frequency

= 890 MHz + 0.2(n) + 45 MHz

Mobile Station Receive Frequency

= 890 MHz + 0.2(n-1024) + 45 MHz

Mobile Station Receive Frequency

= 1850.2MHz + 0.2(n-512) + 80 MHz

Specification

8.0 Monitoring

Monitoring the state of the modem may be done both locally and remotely. This is accomplished by using
the UDP API to monitor configuration settings, GPIO states, and A to D measurements. Modification to
the modem’s configuration settings and GPIO outputs states is also facilitated through the UDP API.

8.1 Temperature

The temperature of the Modem is monitored internally by an analog input. When the temperature exceeds
the specified range, the operator is notified through the Modem Manager.

8.2 Host Voltage

The voltage being supplied to the Host is monitored internally by an analog input. When the supply
voltage exceeds the specified range the operator is notified through the Modem Manager and RF
transmission is suspended.

9.0 Control Connector Signal Descriptions

9.1 Serial Interface

The modem provides a standard 16550 UART serial interface to the host. It provides a full 9-pin, RS-232
interface at logic level (3.3 V). TxData is the serial data from the modem. RxData is the serial data from the
host to the modem. This data may contain 7 or 8 data bits, and 1 stop bit. The baud rate may be adjusted to
19200 or 38400 bits per second. Default settings are 8 data, 1 stop, no parity, and 38400 baud. DCD may
be set to be always on or to indicate GPRS connection status. DTR may be used to force the modem into
AT command mode from online data mode. RTS and CTS may be used for hardware handshaking. DSR is
always active (connected to ground) while the modem is on. RING may be used to alert the host to
incoming messages by pulsing when the modem is in sleep state and a new message arrives from the
network. For a minimal implementation, connect RxData and TxData to the COM port serial data lines,
connect DTR and RTS to GND.

9.2 GPIO

Eight general-purpose signals (GPIO1-8) are provided. Each of these signals may be selected as inputs or
outputs. They may be used independently as a user-specified function, or may be used to provide modem

CONFIDENTIAL - SEE CONFIDENTIALITY RESTRICTIONS ON TITLE PAGE

control and status signals. Two examples of modem control signals are: register/deregister on GPRS
network command and transmitter disable. One modem status signal example is GPRS registration status.
These GPIO pins are controlled with AT commands and/or by the UDP control interface. GPIO signals
will only be active when the modem is in receive or transmit power consumption mode.

9.3 Wake Circuit

The WAKE signal is used to wake the modem up from sleep.

9.4 A-to-D Inputs

Two analog-to-digital conversion signals are provided for the user; ADC1 and ADC2. The binary
resolution is 8 bits that have a readable input voltage range of 3.0 to 3.2V. These signals may be read with
AT commands or the API control interface.

9.5 Transmit Indicator (TX IND)

The transmit indicator output alerts the Host when the modem is in transmit mode. The transmitter
indicator will be high when the modem is in transmit mode.

10.0 Software

10.1 Operating Systems

The Enabler-G Host Modem Manager software supports Windows CE 3.0 (Windows for Pocket PC 2000)
and Windows 98 Second Edition. Future versions of the Enabler-G Modem Manager will support other
Windows operating systems.

10.2 Modem Manager

The Enabler-G Modem Manager will allow configuration of the modems parameters as well as real time
monitoring of the GPRS network details such as sensitivity and channel.
The Modem manager will also automatically detect the modem when the application is launched.

10.3 Communication Protocol

Enabler-G supports a common AT command set, ICMP, and UDP PAD. Enabler-G also supports TCP/IP,
and SLIP protocols initiated through Dial-Up networking. With this configuration, Internet Explorer,
Netscape, MS Outlook, and other TCP/IP protocol based applications are supported by the modem.

12.0 Regulatory Information

FCC REGULATORY COMPLIANCE

INTEGRATION AND USE INFORMATION

INTEGRATION CONSIDERATIONS AND INSTALLATION REQUIREMENTS

The Enabler-G OEM GPRS modem is designed for use in a variety of host units, "enabling" the host platform to
perform wireless data communications. However, there are certain criteria relative to integrating the modem into a
host platform such as a PC, laptop, handheld or PocketPC, monitor and control unit, etc. that must be considered to
ensure continued compliance with FCC compliance requirements.

The modem was tested and certified to meet FCC Parts 15 and 24 in a stand-alone configuration, demonstrating that
the Enabler-G complies with Part 15 emission limits regardless of the device into which it may be installed. Further,
to provide relief in certain applications for the host integrator, the Enabler-G was approved under the "modular
approval" process for a transmitter. This approach, described by FCC Public Notice DA 00-131407 released June
26, 2000, is intended to afford relief to equipment manufacturers by eliminating the requirement for obtaining a new
equipment authorization for the same transmitter when installed in a new device.

However, the host platform integrator must follow all installation instructions and cautionary information necessary
to comply with FCC RF exposure requirements.

In order to use the Enabler-G without additional FCC certification approvals, the installation must meet the
following conditions. Otherwise, additional FCC approvals must be obtained.

1. “Fixed” and “mobile” applications: At least 20 cm (7.9 in.) separation distance between the antenna and
the user’s body must be maintained at all times. For the transmitter to meet the MPE categorical exclusion
requirements of 2.1091, the ERP must be less than 1.5 watts for personnel separation distance of at least 20
cm (7.9 in).

a. In “Fixed” applications, antenna gain is limited to a maximum of 7 dBi, with a corresponding

Equivalent isotropic Radiated Power (EIRP) of 37 dBm / 5 W.

b. In “mobile” applications, antenna gain is limited to a maximum of 3 dBi, with a corresponding

Equivalent isotropic Radiated Power (EIRP) of 37 dBm /25 W

c. If greater than 1.5 watts exists, then additional testing and FCC approval is required (e.g., see 3 below).

2. If used with a desktop or other application where the antenna can be easily relocated to meet the 20 cm
criteria, then this is considered a “mobile” application.

If used in a "mobile" application where the antenna is normally separated at least 20 cm (7.9 in) from the
human body during device operation, then an appropriate warning label must be placed on the host unit
adjacent to the antenna.

The label should contain a statement such as the following:

WARNING
RF exposure. Keep at least 20 cm
(7.9 in) separation distance from
the antenna and the human body.

3. “Portable” applications: If used in a "portable" application such as a handheld device with the antenna
less than 20 cm (7.9 in.) from the human body when the device is operating, then the integrator is
responsible for passing additional "as installed" testing.

CONFIDENTIAL - SEE CONFIDENTIALITY RESTRICTIONS ON TITLE PAGE

Page

11 of 14

Separate FCC approval for RF exposure compliance is required for end products that do not met the
separation or maximum antenna gain criteria.

a. SAR (Specific Absorption Rate) testing, with results submitted to the FCC for approval prior to selling

the integrated unit. If unable to meet SAR requirements, then the host unit must be restricted to
"mobile" use (see 3 below).

b. Unintentional emissions, FCC Part 15; results do not have to be submitted to the FCC unless

requested, although the test provides substantiation for required labeling (see 5 below).

4. Host unit user manuals and other documentation must also include appropriate caution and warning
statements and information.

5. If the FCC ID for the modem is not visible when installed in the host platform, then a permanently attached
or marked label must be displayed on the host unit referring to the enclosed modem. For example, the label
should contain wording such as:

Contains CDPD modem transmitter module

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) This device must accept any interference
received, including interference that may cause
undesired operation.

FCC ID: MIVGSM0103

or

Contains FCC ID: MIVGSM0103

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) This device must accept any interference
received, including interference that may cause
undesired operation.

6. Any antenna used with the modem must be approved by the FCC as either a Class II Permissive Change
(including MPEL or SAR data as applicable). The "professional installation" provision of FCC Part 15.203
does not apply.

7. The transmitter and antenna must not be co-located or operating in conjunction with any other antenna or

transmitter. Violation of this would allow a user to plug another transmitter in to the product and
potentially create an RF exposure condition.

WARNING
The transmitter and antenna must not be co­located or operating in conjunction with any
other antenna or transmitter. Failure to observe
this warning could produce an RF exposure
condition.
