2.2.1 RF Functionalities
The Radio Frequency (RF) functionalities complies with the Phase II EGSM 900/DCS
1800 and GSM 850/PCS 1900 recommendation. The frequencies are:
Transmit band (Tx) Receive band (Rx)
GSM 850 824 to 849 MHz 869 to 894 MHz
E-GSM 900 880 to 915 MHz 925 to 960 MHz
DCS 1800 1710 to 1785 MHz 1805 to 1880 MHz
PCS 1900 1850 to 1910 MHz 1930 to 1990 MHz
The Radio Frequency (RF) part is based on a specific quad-band chip with a:
• Quad-band LNAs (Low Noise Amplifier)
• Direct Conversion Receiver
• Offset PLL/PL (Phase Locked Loop and Polar Loop) transmitter
• Frequency synthesizer
• Digitally controlled crystal oscillator (DCXO)
• Tx/Rx FEM (Front-End module) for quad-band GSM/GPRS
2.2.2 Baseband Functionalities
The digital part of the Wireless CPU Quik Q2687 is composed of a PCF5213 PHILIPS
chip. This chipset uses a 0,18 µm mixed technology CMOS, which allows massive
integration as well as low current consumption.
2.3 Operating System
Wireless CPU Quik Q2687 is designed to integrate various types of specific process
applications such as vertical applications (telemetry, multimedia, automotive).
The Operating System offers a set of AT commands to control the Wireless CPU. With
this standard Operating System, some interfaces of the Wireless CPU are not
available, since they are dependent on the peripheral devices connected to the
Wireless CPU.
The Operating System is Open AT® compliant.

3.2 Power Supply
The power supply is one of the key issues in the design of a GSM terminal.
Due to the burst emission mode used in GSM / GPRS, the power supply must be able
to deliver high current peaks in a short time. During the peaks, the ripple (Uripp) on
the supply voltage must not exceed a certain limit (see Table 1 Power supply
voltage).

Figure 2: Power supply during burst emission
In communication mode, a GPRS class 10 terminal emits 1154µs radio bursts every
4.615ms.
Only the VBATT power supply input is necessary to provide the Q2687 Wireless CPU.
VBATT:
• Directly supplies the RF components with 3,6 V. It is essential to keep a
minimum voltage ripple at this connection in order to avoid any phase error.
The RF Power Amplifier current (2.0 A peak in GSM /GPRS mode) flows with a
ratio of:
o 1/8 of the time (around 577µs every 4.615ms for GSM /GPRS class 2),
o 2/8 of the time (around 1154µs every 4.615ms for GSM /GPRS class 10)
and
o The rise time is around 10µs.
• Is internally used to provide via several regulators, the VCC_2V8 and VCC_1V8,
the power supply required for the base band signals.
Wireless CPU Quik Q2687 shielding case is the grounding. The ground plane has to
be connected to the motherboard through a complete layer on the PCB.

(1): This value has to be maintained during the burst (with 2.0A Peak in GSM, GPRS
or EGPRS mode)
(2): The maximum operating Voltage Stationary Wave Ratio (VSWR) is 2:1
When supplying the Wireless CPU from a battery, the total impedance (battery +
protections + PCB) should be <150 mOhms.
Caution:
When the Wireless CPU is in Alarm mode, no voltage must be applied on any pin of
the 100-pin connector except on BAT-RTC (pin 7) for RTC operation or ON/~OFF (pin
19) to power ON the Wireless CPU.
3.2.1 Power Consumption
Power consumption is dependent on the configuration used. It is for this reason that
the following consumption values are given for each mode, RF band and type of
software used (AT or Open AT™).
All the following information is given assuming a 50 Ω RF output.
The following consumption values were obtained by performing measurements on
Wireless CPU samples at a temperature of 25° C.
Three VBATT values are used to measure the consumption, VBATTmin (3.2V),
VBATTmax (4.5V) and VBATTtyp (3.6V).
The average current is given for the three VBATT values and the peak current given is
the maximum current peak measured with the three VBATT voltages.
For a more detailed description of the operating modes, see the Appendix of the AT
Command Interface Guide OS 6.61 [4]
For more information about the consumption measurement procedure, see Wireless
CPU Quik Q2687 Customer Design Guidelines [2].
3.2.1.1 Power Consumption without Open AT® Processing

3.7 Main Serial Link (UART1)
A flexible 6-wire serial interface is available, complies with V24 protocol signaling,
but not with V28 (electrical interface) due to a 2.8-Volt interface.
The signals are as follows:
• TX data (CT103/TX)
• RX data (CT104/RX)
• Request To Send (~CT105/RTS)
• Clear To Send (~CT106/CTS)
• Data Terminal Ready (~CT108-2/DTR)
• Data Set Ready (~CT107/DSR).
The set of RS-232 signals may be required for GSM DATA services application and is
generated by the General Purpose I/O provided by the Wireless CPU Quik Q2687.
The two additional signals are:
• Data Carrier Detect (~CT109/DCD) and
• Ring Indicator (CT125/RI).

3.14.1 Microphone Inputs
The MIC2 inputs already include the biasing for an electret microphone, thus allowing
easy connection.
The MIC1 input requires external biasing, if an electret microphone is used.
3.14.1.1 Common microphone input characteristics
The connection may be either differential or single-ended but use of a differential
connection in order to reject common mode noise and TDMA noise is strongly
recommended. When using a single-ended connection, be sure to have a good
ground plane, good filtering and also shielding, in order to avoid any disturbance on
the audio path.
The gain of the MIC inputs is internally adjusted and may be tuned using an AT
command.
Both may be configured either as differential or single-ended.
3.14.1.2 Main Microphone Inputs (MIC2)
By default, the MIC2 inputs are differential inputs, but may also be configured as
single-ended. MIC2 inputs already include convenient biasing for an electret
microphone. The electret microphone may be directly connected to these inputs.
AC coupling is already embedded in the Wireless CPU.

The connection is single-ended on SPK1 and either a differential or single-ended on
SPK2. Use of a differential connection to reject common mode noise and TDMA noise
is strongly recommended. Moreover, in single-ended mode, ½ of the power is lost.
When using a single-ended connection, be sure to have a good ground plane, a good

3.16 Battery Charging Interface
The Wireless CPU Quik Q2687 supports one battery charging circuit, two algorithms
and one hardware charging mode (pre-charging) for 3 battery technologies:
¾ Ni-Cd (Nickel-Cadmium) with algorithm 0
¾ Ni-Mh (Nickel-Metal Hydride) with algorithm 0
¾ Li-Ion (Lithium-Ion) with algorithm 1
The two algorithms control a switch, which connects the CHG-IN signal to the
VBATT signal. The algorithm controls the frequency and the connected time of the
switch. During the charging procedure, battery charging level is controlled and when
the Li-Ion algorithm is used, battery temperature is monitored via the BAT-TEMP ADC
input.
One more charging procedure is available in the Q2687 Wireless CPU. This is called
"Pre-charging" mode, but is a special charging mode as it is activated only when the
Wireless CPU is OFF. Control is thus performed by the hardware. The purpose of this
charging mode is to avoid battery damage by preventing the battery from being
discharged to below the minimum battery level.
3.16.1 Ni-Cd / Ni-Mh Charging Algorithm
To charge the battery, the algorithm measures battery level when the switch is open
(T2) and charges the battery by closing the switch (T3). When the battery is charged

3.16.2 Li-Ion Charging Algorithm
The Li-Ion algorithm provides battery temperature monitoring, which is highly
recommended to prevent battery damage during the charging phase.
The Li-Ion charger algorithm may be configured into three phases:
1. Constant charge
2. Start of pulse charge
3. End of pulse charge
The three phases can be seen in the following waveform diagram for full-charging:

3.16.3 Controlled Pre-charging Hardware
The pre-charging mode which is hardware controlled (but not the software
controlled) is also available. This mode is only activated when the Wireless CPU is
OFF and when VBATT is in the voltage range of 2.8V < VBATT < 3.2V. The charger
power supply must be connected to CHG-IN (pin 6,8). In pre-charging mode, the
battery is charged with a direct current of 50mA. The FLASH-LED blinks, when this
mode is activated.
This mode is not a real charging mode as it is not possible to obtain a full charge with
it, but it is useful to save the battery life by preventing the battery from being
discharged to below the low limit voltage value.
3.16.4 Temperature Monitoring
Temperature monitoring is only available for the Li-Ion battery with algorithm 1. The
BAT-TEMP (pin 20) ADC input must be used to sample the temperature analog signal
provided by an NTC temperature sensor. The minimum and maximum temperature
range may be set by AT command.

3.17 ON / ~OFF Signal
This input is used to switch the Wireless CPU Quik Q2687 ON or OFF.
A high-level signal must be provided on the ON/~OFF pin to switch ON the Wireless
CPU. The voltage of this signal must be maintained for a minimum of 3000ms. This
signal may be left at high level until it is switched off.
To switch OFF the Wireless CPU, the ON/OFF pin must be released. The Wireless
CPU may be switched off via the Operating System.
3.17.1 Operating Sequences
3.17.1.1 Power ON
Once the Wireless CPU is supplied, the application must set the ON/OFF signal to
high to start the Wireless CPU power ON sequence. The ON/OFF signal must be held
for 3000ms minimum. After this period, an internal mechanism keeps it on hold.
During the power ON sequence, an internal reset is automatically performed by the
Wireless CPU for 40ms (typical). During this phase, any external reset should be
avoided. Once initialization is complete (timing is SIM- and network-dependent), the
AT interface answers "OK" to the application. For further details, please check the AT
Commands Interface Guide.

3.19 Reset Signal (~RESET)
This signal is used to force a reset procedure by providing low level for at least 200µs.
This signal must be considered as an emergency reset only. A reset procedure is
already driven by the internal hardware during the power-up sequence.
This signal may also be used to provide a reset to an external device (at power up
only). If no external reset is necessary, this input may be left open. If used
(emergency reset), it must be driven either by an open collector or an open drain.
The Wireless CPU remains in reset mode as long as the ~RESET signal is held low.
Caution
This signal should only be used for "emergency" resets.
An Operating System reset is preferred to a hardware reset.
Reset sequence:
To activate the "emergency" reset sequence, the ~RESET signal has to be set to low
for 200µs minimum. Once the reset is completed, the AT interface answers "OK" to
the application.

6 Design Guidelines
The purpose of the following paragraphs is to give design guidelines.
6.1 Hardware and RF
6.1.1 EMC Recommendations
The EMC tests must be performed on the application as soon as possible to detect
any potential problems.
When designing, special attention should be paid to:
• Possible spurious emission radiated by the application to the RF receiver in the
receiver band
• ESD protection is mandatory on all signals which have external accessibility
(typically human accessibility). See Q2687 Wireless CPU Customer Design
Guidelines WM_DEV_Q2687_PTS_007 [2] for ESD protection samples.
o Similarly, ESD protection is mandatory for the:
SIM (if accessible from outside)
Serial link
• EMC protection on audio input/output (filters against 900MHz emissions)
• Biasing of the microphone inputs
• Length of the SIM interface lines (preferably <10cm)
• Ground plane: Wavecom recommends a common ground plane for
analog/digital/RF grounds.
• A metallic case or plastic casing with conductive paint are recommended
Note:
The Wireless CPU does not include any protection against over-voltage.
6.1.2 Power Supply
The power supply is one of the key issues in the design of a GSM terminal.
A weak power supply design could, in particular, affect:
• EMC performance
• The emission spectrum
• The phase error and frequency error

WA_ENG_Q2687_PTS_001-002 September 11, 2006
Warning:
Careful attention should be paid to:
The quality of the power supply: low ripple, PFM or PSM systems should be avoided
(PWM converter preferred).
Capacity to deliver high current peaks in a short time (pulsed radio emission).

WA_ENG_Q2687_PTS_001-002 September 11, 2006
6.1.4 Antenna
Warning:
Wavecom strongly recommends to work with an antenna manufacturer either to
develop an antenna adapted to the application or to adapt an existing solution to the
application.
Both the mechanical and electrical antenna adaptation are one of the key issues in
the design of GSM terminal.
6.2 Mechanical Integration
Attention should be paid to:
• Antenna cable integration (bending, length, position, etc)
• Leads of the Wireless CPU to be soldered to the Ground plane
6.3 Operating System Upgrade
The Wireless CPU Quik Q2687 Operating System is stored in flash memory and may
easily be upgraded.
IMPORTANT:
In order to follow regular changes in the GPRS standard and to offer a state-of-the-art
Operating System, Wavecom recommends that the application designed around a
WISMO (or WISMO based product) allow easy Operating System upgrades on the
Wireless CPU via the standard Xmodem protocol. Therefore, the application shall
either allow a direct access to the WISMO serial link through an external connector or
implement any mechanism allowing the WISMO Operating System to be downloaded
via Xmodem.
The Operating System file may be downloaded to the Wireless CPU using the
Xmodem protocol. The AT+WDWL command allows the download process to be
launched (see the description in the AT Command User Guide).
The serial signals required to proceed with Xmodem downloading are:
Rx, Tx, RTS, CTS and GND.
The Operating System file may also be downloaded to the Wireless CPU using the
DOTA (download over the air) feature. This feature is available with the Open AT®
interface. For more details, please, refer to the Open AT® documentation.

7.2 Safety Recommendations (for Information only)
IMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM APPLICATION
BASED ON WIRELESS CPU QUIK Q2687
PLEASE READ THIS INFORMATION CAREFULLY
7.2.1 RF Safety
7.2.1.1 General
Your GSM terminal1 is based on the GSM standard for cellular technology. The GSM
standard is spread all over the world. It covers Europe, Asia and some parts of
America and Africa. This is the most used telecommunication standard.
Your GSM terminal is actually a low power radio transmitter and receiver. It sends
out as well as receives radio frequency energy. When you use your GSM application,
the cellular system which handles your calls controls both the radio frequency and
the power level of your cellular modem.
7.2.1.2 Exposure to RF energy
There has been some public concern about possible health effects of using GSM
terminals. Although research on health effects from RF energy has focused on the
current RF technology for many years, scientists have begun research regarding
newer radio technologies, such as GSM. After existing research had been reviewed,
and after compliance to all applicable safety standards had been tested, it has been
concluded that the product was fitted for use.
If you are concerned about exposure to RF energy there are things you can do to
minimize exposure. Obviously, limiting the duration of your calls will reduce your

exposure to RF energy. In addition, you can reduce RF exposure by operating your
cellular terminal efficiently by following the guidelines below.
7.2.1.3 Efficient Terminal Operation
For your GSM terminal to operate at the lowest power level, consistent with
satisfactory call quality:
If your terminal has an extendable antenna, extend it fully. Some models allow you to
place a call with the antenna retracted. However, your GSM terminal operates more
efficiently with the antenna when it is fully extended.
Do not hold the antenna when the terminal is "IN USE". Holding the antenna affects
call quality and may cause the modem to operate at a higher power level than
needed.
7.2.1.4 Antenna Care and Replacement
Do not use the GSM terminal with a damaged antenna. If a damaged antenna comes
into contact with the skin, a minor burn may result. Replace the damaged antenna
immediately. You may repair antenna yourself by following the instruction manual
provided to you. If so, use only a manufacturer-approved antenna. Otherwise, have
your antenna repaired by a qualified technician.
Buy or replace the antenna only from the approved suppliers list. Using of
unauthorized antennas, modifications or attachments could damage the terminal and
may violate local RF emission regulations or invalidate type approval.
7.2.2 General Safety
7.2.2.1 Driving
Check the laws and the regulations regarding the use of cellular devices in the area
where you have to drive, as you always have to comply with them. When using your
GSM terminal while driving, please:
• give full attention to driving,
• pull-off the road and park before making or answering a call (if driving
conditions so require).
7.2.2.2 Electronic Devices
Most electronic equipments, for example in hospitals and motor vehicles are shielded
from RF energy. However, RF energy may affect some improperly shielded electronic
equipment.

7.2.2.3 Vehicle Electronic Equipment
Check your vehicle manufacturer representative to determine if any on-board
electronic equipment is adequately shielded from RF energy.
7.2.2.4 Medical Electronic Equipment
Consult the manufacturer of any personal medical devices (such as pacemakers,
hearing aids, etc...) to determine if they are adequately shielded from external RF
energy.
Turn your terminal OFF in health care facilities when any regulations posted in the
area instruct you to do so. Hospitals or health care facilities may be using RF
monitoring equipment.
7.2.2.5 Aircraft
Turn your terminal OFF before boarding any aircraft.
• Use it on the ground only with crew permission.
• Do not use it in the air.
To prevent possible interference with aircraft systems, Federal Aviation
Administration (FAA) regulations require you to have prior permission from the crew
members to use your terminal while the aircraft is on the ground. In order to prevent
interference with cellular systems, local RF regulations prohibit using your modem,
while airborne.
7.2.2.6 Children
Do not allow children to play with your GSM terminal. It is not a toy. Children could
hurt themselves or others (by poking themselves or others in the eye with the
antenna, for example). Children could damage the modem, or make calls that
increase your modem bills.
7.2.2.7 Blasting Areas
To avoid interfering with blasting operations, turn your unit OFF when in a "blasting
area" or in areas posted: "turn off two-way radio". Construction crew often uses
remote control RF devices to set off explosives.
7.2.2.8 Potentially Explosive Atmospheres
Turn your terminal OFF when in any area with a potentially explosive atmosphere. It
is rare, but your modem or its accessories could generate sparks. Sparks in such
areas could cause an explosion or fire resulting in bodily injuries or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fuelling areas such as petrol stations; below decks on boats;

fuel or chemical transfer or storage facilities; and areas where the air contains
chemicals or particles, such as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives, in the compartment of
your vehicle which contains your terminal or accessories.
Before using your terminal in a vehicle powered by liquefied petroleum gas (such as
propane or butane) ensure that the vehicle complies with the relevant fire and safety
regulations of the country in which the vehicle is to be used.
