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
3.2.1 Power supply description
The power supply is one of the key issue in the design of a GSM terminal.
Due to the bursted emission 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 1Power supply
voltage“ Power Supply Voltage”).
In communication mode, a GSM/GPRS class 2 terminal emits 577µs
radio bursts every 4.615ms. (See Figure 2)
Uripp
VBATT
T

T = 4,615 ms
t = 577 µs
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 Q2686
Wireless CPU.
VBATT:
supplies directly 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 Apeak in GSM /GPRS mode) flows
with a ratio of:
o1/8 of the time (around 577µs every 4.615ms for GSM /GPRS cl. 2)
and
o2/8 of the time (around 1154µs every 4.615ms for GSM /GPRS cl.
10).
The rising time is around 10µs.
is internally used to provide through several regulators, the power
supply VCC_2V8 and VCC_1V8 needed for the base band signals.

The WISMO QUIK Q2686 shielding case is the grounding. The ground has to
be connected on the mother board through a complete layer on the PCB.

or GPRS mode)
(2): max operating Voltage Stationary Wave Ratio (VSWR) 2:1
When supplying the Wireless CPU with a battery, the total impedance
(battery+protections+PCB)should be <150 mOhms.
When the Wireless CPU is in Alarm mode, no voltage must be applied on any
pin of the 100-pin connector excepted on the BAT-RTC (pin 7 ) for RTC
operation, or ON/~OFF (pin 19) to power ON the Wireless CPU.
3.2.2 Power consumption
The power consumption is depending of the configuration used. That’s why,
the following consumption values are given for each modes, RF bands and
software used (AT or Open AT™).
All following information are given assuming a 50 RF output.
The following consumption values are given by measurement on Wireless CPU
samples, at temperature of 25°C.
Three VBATT values are used to measure the consumption, VBATTMIN (3.2V),
VBATTMAX (4.8V) and VBATTTYP (3.6V).
The average current is given for the three VBATT values and the peak current
given is the maximal current peak measured with the three VBATT voltages.
For more information about working mode description, see Appendix of AT
Command Interface Guide OS 6.60 [4]
For more information about consumption measurement procedure, see WISMO

3.11 Analogue audio interface
Two different microphone inputs and two different speakers outputs are
supported.
The WISMO Quik Q2686 also includes an echo cancellation feature which
allows handsfree function.
3.11.1 Microphone inputs
The MIC2 inputs already include the biasing for an electret microphone
allowing an easy connection.
The MIC1 input needs to have an external biasing if an electret micro is used.
3.11.1.1 Common microphone inputs characteristics
The connection can be either differential or single-ended but using 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 very
good ground plane, a very good filtering as well as shielding in order to avoid
any disturbance on the audio path.
The gain of MIC inputs is internally adjusted and can be tuned using an AT
command.
Both can be configured in differential or single ended.
3.11.1.2 Main Microphone Inputs (MIC2)
By default, the MIC2 inputs are differential ones, but it can be configured in
single ended. They already include the convenient biasing for an electret
microphone. The electret microphone can be directly connected on those
inputs.
AC coupling is already embedded in the Wireless CPU.

3.11.2 Common speaker outputs characteristics
The connection is single-ended on SPK1 and is differential or single-ended on
SPK2. Using 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 very

3.13 Battery charging interface
The WISMO Quik Q2686 Wireless CPU supports one battery charging circuit, 2
algorithms and one hardware charging mode (Pré-charging) for 3 batteries
technologies:
Ni-Cd (Nickel-Cadmium) with algorithm 0
Ni-Mh (Nickel-Métal Hydrure) with algorithm 0
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 switching. During the charging procedure the battery charging level is
controled and when Li-Ion algorithm is used, the battery temperature is
monitoring thorough the BAT-TEMP ADC input.
One more charging procedure is provided by the Q2686 Wireless CPU. It’s
called “Pre-charging” mode, but it’s a special charging mode because it is
activated only when the Wireless CPU is OFF. So the control is only performed
by the hardware. The goal of this charging mode is to prevent the battery to be
damaged by preventing the discharged under the minimum battery level.
3.13.1 Ni-Cd / Ni-Mh Charging algorithm
To charge the battery, the algorithm measures the battery level when the
switch is opened T2 and charges the battery by closing the switch T3. When
the battery is charged (battery voltage reached BattLevelMax) the switch is
opened during the time T3.

3.13.2 Li-Ion Charging algorithm
The LI-Ion algorithm, provides the temperature monitoring of the battery which
is highly recommended to prevent the damage of battery during the charging
phase.
The Li-Ion charger algorithm can be decomposed in 3 phases :
1. Constant charge
2. Beginning of pulse charge
3. End of pulse charge
The three phases can be seen on the following waveform of a complete
charge:

3.13.3 Pré-Charging hardware controlled
One more charging mode is existing, but it’s not software controlled, it’s the
Pre-charging mode. This mode is only controlled by hardware. This mode is
only activated when the Wireless CPU is OFF and when the VBATT is in this
voltage range : 2.8V < VBATT < 3.2V. Of course, the charger power supply has
to be plugged on the CHG-IN (pin 6,8). During the Pré-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, because it not possible to have a full
charge with it, but it is useful to safe the battery life by preventing the battery
to be discharge under the low limit voltage value.
3.13.4 Temperature monitoring
The monitoring of the temperature is only available for the Li-Ion battery with
the algorithm number 1. The BAT-TEMP (pin 20) ADC input must be used to
sample the temperature analog signal provided by a NTC temperature sensor.
The minimum an maximum temperature range can be set by AT command.

3.14 ON / ~OFF signal
This input is used to switch ON or OFF the WISMO Quik Q2686 Wireless CPU.
A high level signal has to be provided on the pin ON/~OFF to switch ON the
Wireless CPU. The voltage of this signal has to be maintained during a
minimum of 1000ms. This signal can be left at high level until switch off.
To switch OFF the Wireless CPU, the pin ON/OFF has to be released. The
Wireless CPU can be switched off through the Operating System.
3.14.1 Operating sequences
3.14.1.1 Power ON
Once the Wireless CPU 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 hold for 2000ms minimum. After this time, 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 the 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.

3.16 Reset signal (~RESET)
This signal is used to force a reset procedure by providing low level during at
least 200µs. This signal has to be considered as an emergency reset only. A
reset procedure is already driven by an internal hardware during the power-up
sequence.
This signal can also be used to provide a reset to an external device (at power
up only ). If no external reset is necessary this input can be left open. If used
(emergency reset), it has to be driven 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 be used only for “emergency” resets.
An Operating System reset will be preferred to an hardware reset.
Reset sequence :
To activate the «emergency » reset sequence, the ~RESET signal has to be set
to low for 200s minimum. As soon as the reset is complete, the AT interface
answers « OK » to the application.

The ~RESET time is provided by the internal RC component. To keep the same
time, it’s not recommended to plug an other R or C component on the ~RESET
signal. Only a switch or an open drain gate is recommended.
The Ct time is the cancellation time needed for the wireless CPU Q2686
initialization. Ct time is automatically done by the Q2686 Wireless CPU after a
hardware reset.

6Design 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 have to be performed as soon as possible on the application to
detect any possible problem.
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 WISMO Quik Q2686
Customer Design Guidelines WM_PRJ_Q2686_PTS_003 [2] for ESD
protection samples.
oTypically ESD protection is mandatory for :
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 to have a common ground
plane for analog / digital / RF grounds.
Metallic case or plastic casing with conductive paint are recommended
Note :
The Wireless CPU does not include any protection against overvoltage.
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 affect in particular :
EMC performances
the emissions spectrum
the phase error and frequency error
WARNING:
Careful attention should be paid to :

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 is one of the key issues
in the design of the GSM terminal.
6.2 Mechanical integration
Attention should be paid to :
Antenna cable integration (bending, length, position, etc)
Legs of the Wireless CPU to be soldered on the Ground plane
6.3 Operating System upgrade
The WISMO Quik Q2686 Operating System is stored in flash memory and it
can easily be upgraded.
IMPORTANT:
In order to follow the regular evolutions of the GPRS standard and to offer state
of the art Operating System, Wavecom recommends that the application
designed around a WISMO (or WISMO based product) allows 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 can be downloaded into the modem using the
Xmodem protocol. AT+WDWL command allows to launch the download
process (see description in the AT command User Guide.
The necessary serial signals to proceed with the Xmodem downloading are:
Rx, Tx, RTS, CTS and GND.
The Operating System file can be also downloaded into the modem using the
DOTA (download over the air) feature. This feature is available with Open AT®
interface. For more detail, 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 WISMO Quik Q2686
PLEASE READ THIS INFORMATION CAREFULLY
7.2.1 RF safety
7.2.1.1 General
Your GSM terminal1is 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 and 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 below guidelines.
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 extendible 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 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.

des tiers sans son autorisation préalable.
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 a damaged
antenna immediately. Consult your manual to see if you may change the
antenna yourself. If so, use only a manufacturer-approved antenna. Otherwise,
have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorized antennas,
modifications or attachments could damage the terminal and may contravene
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 equipment, for example in hospitals and motor vehicles is
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 permission from a crew
member to use your terminal while the aircraft is on the ground. 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 use 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.
