2.2.1 RF functionalities

The Radio Frequency (RF) range comply 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 including:

 a Digital low-IF receiver  a Quad-band LNAs (Low Noise Amplifier)  an Offset PLL (Phase Locked Loop) transmitter  a Frequency synthesizer  a Digitally controlled crystal oscillator (DCXO)  a Tx/Rx FEM ( Front-End Wireless CPU) for quad-band GSM/GPRS

2.2.2 Baseband functionalities

The digital part of the WISMO Quik Q2686 is composed of a PCF5212 PHILIPS chip. This chipset is using a 0,18 µm CMOS mixed technology, which allows massive integration as well as low current consumption.

2.3 Operating System

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 (U the supply voltage must not exceed a certain limit (see Table 1 Power 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

ripp

) on

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 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 cl. 2)

and

o 2/8 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.

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.

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

good ground plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path.

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.

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.

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.

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 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.

o Typically 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.

based on WISMO2D

WM_PRJ_Q2686_PTS_001

April 4th 2006

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.

WM_PRJ_Q2686_PTS_001

April 4th 2006

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.
