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)UrippVBATTTUrippT = 4,615 mst = 577 µsFigure 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.

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 Quik Q2686 Customer Design Guidelines [2].

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 algorithmTo 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.BattLevelMaxT1T2 T3Battery LevelSwitch StateopenedclosedFigure 5: Ni-Cd / Ni-Mh charging waveformElectrical Characteristics of Ni-Cd / Ni-Mh battery timing chargeParameter Min Typ Max UnitT1 1 sT2 0.1 sT3 5 sNote : T1,T2,T3 and BattLevelMax can be configured by AT command.The battery level is monitoring by the software but not the temperature.

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 monitoringThe 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.

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 sequences3.14.1.1 Power ONOnce 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.

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 recommendedNote :The Wireless CPU does not include any protection against overvoltage.6.1.2 Power SupplyThe 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 errorWARNING:Careful attention should be paid to :

Il ne peut être communiqué ou divulgué à des tiers sans son autorisation préalable.6.1.4 AntennaWARNING: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 integrationAttention should be paid to : Antenna cable integration (bending, length, position, etc) Legs of the Wireless CPU to be soldered on the Ground plane6.3 Operating System upgradeThe 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.

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 energyThere 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 operationFor 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.1based on WISMO2D

Il ne peut être communiqué ou divulgué à des tiers sans son autorisation préalable.7.2.1.4 Antenna care and replacementDo 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 safety7.2.2.1 DrivingCheck 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 devicesMost 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 equipmentCheck your vehicle manufacturer representative to determine if any on-board electronic equipment is adequately shielded from RF energy.7.2.2.4 Medical electronic equipmentConsult 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.

Il ne peut être communiqué ou divulgué à des tiers sans son autorisation préalable.7.2.2.5 AircraftTurn 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 ChildrenDo 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 areasTo 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 atmospheresTurn your terminal OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem or its accessories could generatesparks. 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.
