WA_ENG_Q2687_PTS_001-002 September 11, 2006 In communication mode, a GSM/GPRS class 2 terminal emits 577µs radio bursts every 4.615ms (See the Figure 2). Uripp VBATTT Uripp 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 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.

WA_ENG_Q2687_PTS_001-002 September 11, 2006 (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.

WA_ENG_Q2687_PTS_001-002 September 11, 2006 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 (battery voltage reaches BattLevelMax) the switch is open for time T3.

The Li-Ion charger algorithm may be configured into three phases: 1. Constant charge 2. Start of pulse charge 3.

WA_ENG_Q2687_PTS_001-002 September 11, 2006 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.

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.

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.

It is generated by the internal voltage supervisor. The ~RESET time is provided by the internal RC component. In order to keep the same time, avoid connecting another R or C component on the ~RESET signal. Only a switch or an open drain gate is recommended. Ct is the cancellation time required for Wireless CPU initialization. Ct is automatically carried out by after hardware reset.

WA_ENG_Q2687_PTS_001-002 September 11, 2006 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 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.

WA_ENG_Q2687_PTS_001-002 September 11, 2006 IMPORTANT: Manufacturers of mobile or fixed devices incorporating Q2687 Wireless CPU are advised to: • clarify any regulatory questions, • have their completed product tested, • have product approved for FCC compliance, and • include instructions according to above mentioned RF exposure statements in end product user manual. Please note that changes or modifications not stated clearly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 1 based on WISMO2D

WA_ENG_Q2687_PTS_001-002 September 11, 2006 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.
Wireless CPU Quik Q2687 Appendix ©Confidential Page: 91 / 92 This document is the sole and exclusive property of Wavecom. Not to be distributed or divulged without prior written agreement. WA_ENG_Q2687_PTS_001-002 September 11, 2006 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;
