1.2 Glossary
Term
Definition
Performing a FIX
Means the GPS receiver is able to compute a
position
Dead reckoning
GPS Feature that allows navigation with poor/no
satellites view by the aid of external sensors that
provide course (odometer) and heading
(gyroscope).
Single Coax
WAVECOM concept that allows the user to use
only one single coaxial cable for both GSM and
GPS RF signal to connect the WISMO Quik Q2501
module to the antennas.
The antennas are most of the time physically
distinct but connected to the WISMO Quik Q2501
module by a single coaxial cable through an
antenna switch system, saving a second coaxial
cable.
Cold Start
Powering up a unit after it has been turned off for
an extended period of time and no longer contains
current ephemeris data. In Cold Start Scenario, the
receiver has no knowledge on last position,
approximate time or satellite constellation. The
receiver starts to search for signals blindly. This is
normal behavior, if no backup battery is connected.
Cold Start time is the longest startup time for GPS
receivers and can be several minutes.

Hot Start
Start mode of the GPS receiver when current
position, clock offset, approximate GPS time and
current ephemeris data are all available. In Hot
Start Scenario, the receiver was off for less than
2 hours. It uses its last Ephemeris data to calculate
a position fix.
Warm Start
Start mode of a GPS receiver when current
position, clock offset and approximate GPS time are
known. Almanac data is retained, but the
ephemeris data is cleared. In Warm Start Scenario,
the receiver knows - due to a backup battery or by
other techniques – his last position,
approximate time and almanac. Thanks to this, it
can quickly acquire satellites and get a
position fix faster than in cold start mode.
Coarse Acquisition
Code (C/A Code)
The standard positioning signal the GPS satellite
transmits to the civilian user. It contains the
information the GPS receiver uses to fix its position
and time. Accurate to 24 meter. This code is a
sequence of 1023 pseudorandom binary biphase
modulations on the GPS carrier (L1) at a chipping
rate of 1.023 MHz, thus having a code repetition
period of 1 millisecond. The code was selected to
provide good acquisition properties. Also known as
the "civilian code.".

1.8 GPS active antenna management
Wismo Quik Q2501 module can manage a GPS active antenna in both default
RF connection and Single Coax mode. This function can be useful to protect the
module power supply.
Active antenna management is in charge of the GSM baseband and is based on
a current consumption monitoring:
•
Connected: current consumption is within the limits
•
Short circuit: antenna current consumption over the upper limit; the
antenna is automatically disconnected to protect power supply.
•
Open circuit: the antenna current consumption is below the lower limit.
This information is not available in Single Coax configuration.
Specific AT commands are available in both internal and external for this
function (see [5] for details).

2.2.1 Important notes
1. Some of the WISMO interface signals are multiplexed in order to limit
number of pins but this architecture implies some limitation.
2. All external signals must be inactive when the WISMO module is OFF to
avoid any damage when starting and allow WISMO module to start
correctly.
3. The WISMO Quik Q2501 shielding case is the grounding.
2.2.2 Minimum requirements for application
To be able to drive correctly the WISMO Quik Q2501 module, the use of some
interfaces is mandatory on the customer application. These interfaces are given
in Figure 6 (displayed in bold characters).

Description
Main power supply
The power supply constraints for GPS are not critical compared to GSM/GPRS.
Actually, the power supply is one of the key issues in the design of a GSM/GPRS
application. Due to the bursted nature transmission, the power supply must be
able to deliver high current peaks in a short time.
The GSM RF Power Amplifier current flows with a ratio of:
Max current 1/8 of the time
GSM/GPRS class 2 – 2 RX / 1 TX),
(around
577 µs
every
4.615 ms
for
Max current 2/8 of the time (around 1154 µs every 4.615 ms for
GSM/GPRS class 10 – 3 RX / 2 TX).

Because VBATT supplies directly the GSM RF power amplifier component, it is
essential to keep a minimum voltage ripple at this connection in order to avoid
any phase error or spectrum modulation degradation. See paragraph 2.9
Electrical characteristics for detailed information.

RTC back-up power supply
If using the WISMO Quik Q2501 internal Real Time Clock (RTC), it is necessary
to provide a back-up power supply because:
•
When the WISMO Quik Q2501 module is powered on, the RTC power
supply is provided by the module.
When the WISMO Quik Q2501 module is powered off, a back-up power supply
is needed to save RTC date and time information for GSM part and to save
Backup RAM with RTC data, valid almanac and ephemeredes to perform a Hot
start or a War mstart for GPS part (The GPS will perform a FIX faster).
Nevertheless, since it is possible to retrieve GPS time and date information, it is
not necessary to use this backup power supply interface.
If the RTC is not used, this pin can be left open.
Note: Only after GPS have been supplied, the RTC section and the back-up
battery switch will be initialized properly. If only VCC_RTC is applied first, the
current consumption of the RTC and back up SRAM is undetermined.

General description
This input is used to switch ON or OFF the WISMO Quik Q2501 module.
A high logic level has to be provided on the ON/~OFF pin to switch the module
on. This signal can be left at high level until switching the module off.
To be able to switch the module off, the ON/~OFF pin has to be released before
using AT+CPOF command through the firmware.

Operating sequences
2.5.2.2.1 Power ON
Once the module is supplied by the power source, the application must set the
ON/~OFF signal to high to start the module power ON sequence.
The ON/~OFF signal must be held for 1 s minimum. After this time, an internal
mechanism keeps it on hold.
During the power ON sequence, an internal reset is automatically performed by
the module for 240 ms (typical) 560 ms (max).
During this phase, any external reset should be avoided.(External Reset is an
emergency Reset).
Once the initialization is complete (timing is SIM and network dependent) the AT
interface answers « OK » to the application. For this, the application has to send
AT↵.
If the application manages hardware flow control, the AT command can be sent
during the initialization phase. Another solution is to use the AT+WIND
command to get an unsolicited status from the module.
For further details, please refer to the AT commands documentation (AT+WIND,
AT+WAIP).

If the standard X-modem download procedure does not work correctly, an
alternative download procedure can be selected with the BOOT pin. This
alternative procedure requires a specific downloading software tool.
The Alternative Download procedure can be used for both the GSM & GPS

General description
The ~RST signal is used as an input to force a reset procedure by providing low
level. This reset procedure has to be considered as an emergency reset or for
alternative download procedure described above.
This signal can also be used as an output to provide a reset to an external
device. If no external reset is necessary this pin can be left open.

Additional comments on reset process:
The reset process is activated EITHER by the external ~RST signal OR by an
internal signal (coming from a reset generator). This automatic reset is activated
at Power-up.
The module remains in RESET state mode as long as the ~RST signal is held
low.
Warning: A software reset is always preferred to a hardware reset. This signal
should be used only for “emergency” resets.

Reset sequence
To activate the « emergency » reset sequence, the ~RST signal has to be set to
low for 500 µs minimum.
As soon as the reset is complete, the AT interface answers « OK » to the
application. For this, the application has to send AT↵. If the application manages
hardware flow control, the AT command can be sent during the initialization
phase. Another solution is to use the AT+WIND command to get an unsolicited
status from the module.
For further details, refer to AT commands documentation [4].

2.6.6 Audio interface
Two different microphone inputs (MIC1 and MIC2) and two different speaker
outputs (SPK1 and SPK2) are supported.
Main audio interface is made up of MIC2 inputs (microphone) and SPK2 outputs
(speaker).
Auxiliary audio interface is made up of MIC1 inputs (microphone) and SPK1
outputs (SPK1). Auxiliary audio interface is appropriate for a hands-free system
or a handset with biasing external to the module.
The WISMO Quik Q2501 module also includes echo cancellation and noise
reduction features improving quality of hands-free function.
In some cases, ESD protection must be added on the audio interface lines.
2.6.6.1
Microphone inputs
2.6.6.1.1 General description
The main microphone inputs (MIC2) already include the biasing for an electret
microphone allowing an easy connection to a handset.
The auxiliary microphone inputs (MIC1) do not include an internal bias.
For both microphone paths the connection can be either differential or singleended but using a differential connection in order to reject common mode noise
and TDMA noise is strongly recommended.
The use of a single-ended connection requires a very good ground plane, a very
good filtering as well as shielding in order to avoid any disturbance on the audio
path.
2.6.6.1.2 Main Microphone Inputs (MIC2)
MIC2 inputs include an internal convenient biasing for an electret microphone.
This electret microphone can be directly connected on these inputs, either in
differential or single-ended mode.
The gain is internally adjusted through AT commands.
AC coupling is already embedded in the module.

2.6.6.1.3 Auxiliary Microphone Inputs (MIC1)
MIC1 inputs do not include internal bias, making these inputs the standard ones
for an external headset or a hands-free kit, connected either in differential or
single-ended mode.
Note: to get a good TDMA noise filtering for the biasing of MIC1, a
recommended solution is the use of an external supply instead of using VCC (pin
60) provided by the WISMO Quik Q2501 module.
To use these inputs with an electret microphone, bias has to be generated
outside the WISMO Quik Q2501 module according to the characteristics of this
electret microphone.
AC coupling is already embedded in the module.

2.7 GPS interface
2.7.1 GPS activation
The GPS function can be activated/deactivated either by software or by
hardware command through the GPS_EN signal available on the system
connector and acting as:
An input when GPS activation is hardware controlled,
An output when GPS activation is software controlled; in that case,
GPS_EN output is externally used as a GPS activation indicator.
The choice between hardware or software control is performed by AT command
(see AT+WGPSM command in document [5]).
In case of conflict between hardware control and software control, the latest one
has priority.
Hardware Activation:
Hardware activation pin for GPS function is available on the system connector
(GPS_EN):
high logic level: enable the GPS section.
The voltage level of this signal has to be maintained between 2.4 V and
VBATT.
low logic level: disable the GPS section.
Software Activation:
GPS function activation/deactivation is controlled by AT commands (see AT
WGPSM command in document [5]).
When software control is selected, any action on GPS_EN input is without effect.

2.7.3 Dead reckoning interface
WISMO Quik Q2501 module provides a full-digital interface for dead reckoning
function: SPI bus (GPS_SCK, GPS_MOSI and GPS MISO) with 2 different chip
select (GPS_PCS0_N and GPS_PCS1_N), and 2 GPI (GPS_REVERSE and
GPS_EXTINT0).
The SPI bus is used to drive an ADC for temperature monitoring (GPS_PCS0_N)
and for gyroscope (GPS_PCS1_N).
The distance information is given by the odometer and optionally by the reverse
indicator.

2.9.1.7.4 Power consumption in GSM/GPRS/GPS mode
GSM/GPRS/GPS consumption is the addition of both GSM/GPRS and GPS
consumptions.
GPS antenna supplied through the GPS_VANT pin is independent of VBATT
consumption. However, when using the GPS_VANT input for supplying the GPS
antenna, it can be considered that if the GPS antenna consumption is 10 mA,
this value can be added to VBATT consumption. That rule is also valid when
using the internal power source (LDO) for supplying the GPS antenna.

3 RF interface
3.1 RF connectors
The RF connections between the WISMO Quik Q2501 module and the customer
application is made by two MMS type coaxial connectors, manufactured by
Radiall.
Both RF connectors are available on the top side of the module, named:
•
GSM/DCS RF connector
•
GPS RF connector
The MMS connector stands on three pliable legs in order to guarantee the
receptacle stability after the placement. A snap-on mating system ensures a
correct positive connection each time.
Detailed information about MMS connector is available in this document,
paragraph RF Connector data sheet, 6.4.
According to RF interface configuration described in § 1.7.3, these connectors
are used differently:
•
Default configuration: GSM/DCS antenna connected to GSM/DCS RF
connector and GPS antenna connected to GPS RF connector.
•
Single Coax configuration: only one coaxial cable connected to GSM/DCS
RF connector to drive GSM/DCS and GPS antenna.
Figure 21: Default configuration
Figure 22: Single Coax configuration
Note:
WAVECOM strongly recommends not to use IMS plug equivalent connectors,
because it does not mate correctly with the Radiall receptacle.

In Single Coax configuration:
when the module is in idle mode (GSM or GPRS), loss is < 0.1 dB in C/N,
when the module is in GSM TCH/FS or TCH/data mode, loss is roughly
4 dB in C/N.
Because of high number of GSM slots allocated in packet data transmission
(GPRS), the use of single coax configuration is not recommended with GPRS.

Note:
If a classical patch antenna is followed by an LNA, care must be taken
when placing the antennas: the DCS1800 transmission can saturate the
GPS thus decreasing the GPS performances.
if combined antennas are used, isolation of GSM/DCS & GPS is a key
parameter.

6.2 Safety recommendations (for information only)
IMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM APPLICATION BASED ON WISMO Quik Q2501
PLEASE READ THIS INFORMATION CAREFULLY
6.2.1 RF safety
6.2.1.1
General
Your application using the WISMO Quik Q2501 module 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 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.
6.2.1.2
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.
6.2.1.3
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.

WM_PRJ_Q2501_PTS_001 – 003
March 2004
6.2.1.4
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.
6.2.2 General safety
6.2.2.1
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.
6.2.2.2
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.
6.2.2.3
Vehicle electronic equipment
Check your vehicle manufacturer representative to determine if any on-board
electronic equipment is adequately shielded from RF energy.
6.2.2.4
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.

March 2004
6.2.2.5
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.
6.2.2.6
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.
6.2.2.7
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.
6.2.2.8
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
compartment of your vehicle which contains your terminal or accessories.
the
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.
