WAVECOM: new developments in the wireless market

WAVECOM SA, the world leader in the development and production of wireless GSM / GPRS / CDMA modules, in early 2004 announced new advanced developments that have no analogues in the wireless market.

WAVECOM SA is a dynamically developing company. Its main business area is industrial devices for wireless data transmission in GSM / GPRS / CDMA standards. The activities of WAVECOM are primarily focused on scientific and technical research and the development of new models. The main research centers of the company are located in France, China and the USA, and production is concentrated in Europe and Asia. The company's shares are listed on the NASDAQ and Nouveau Marche. The revenues of the sales market for industrial GSM / GPRS / CDMA modems in 2003 amounted to 130 million euros with an increase of 33% compared to 98 million euros in 2002. In 2004, WAVECOM significantly expanded the range of solutions that will allow it even more strengthen market leadership.

Today WAVECOM GSM / GPRS / CDMA modules are successfully used in ATMs and POS terminals, in remote control systems of vehicles, in vending machines, in gas stations, in the production of mobile phones and PDAs, in measuring, security and navigation systems, in telemedicine , automotive electronics and other applications.

This year, WAVECOM has developed and launched the production of new innovative wireless devices. One of such devices is the WISMO Quik Q2501 combined GSM / GPRS / GPS module, which is focused on applications in the automotive industry. WISMO Quik Q2501 is a unique device that combines the ability to transmit voice and data in GSM / GPRS mode and GPS functionality in one miniature module. Model WISMO Quik Q2501 with dimensions of only 58 x 32 x 6 mm and weighing less than 15 g does not currently have world analogues. The expanded operating temperature range of -35 ... + 85 ° С allows the use of Q2501 series modems in adverse industrial conditions.

WISMO Quik Q2501 is a two-channel GSM / GPRS-module (E-GSM / GPRS-900/1800 MHz), compatible with the ETSI GSM Phase 2+ standard (GSM / GPRS, class 10) with 32 Mbit Flash memory and 4 Mbit SRAM. The built-in 16-channel NMEA-0183 GPS receiver provides high positioning accuracy. Flexible operating modes allow you to use GSM / GPRS and GPS functions both independently of each other and together. Offline mode provides direct access to GPS data regardless of the possibility of connecting to a GSM network; GSM Master mode associates GPS data with GSM. The module is controlled using a set of 550 AT commands; to control the GPS receiver, WAVECOM has developed a special set of AT commands.

The new development contains an integrated TCP / IP stack, which allows you to establish connections such as TCP / IP, POP3 and SMTP without using an additional hardware and software complex. The module implements the ability to embed additional user applications in the flash-memory of the module.

The following conclusions are combined on the 80-pin connector of Q2501 series modules: power supply, SIM card, parallel (8-bit) audio, keyboard (5 lines / 5 speakers), 2 SPI buses, GPIO interface (6 GPIO / 4 GPO / 1 GPI), ADC / DAC, 1 LED, 2 RS-232 (GSM / GPRS), 2 RS-232 (GPS), navigation reckoning, sync. The appearance of WISMO Quik 2501 is shown in Fig. one.

A new development announced by WAVECOM in 2004 was also the Q2400 module, which complements the WISMO Quik family (Fig. 2). The WISMO Quik Q2400 module is designed for use in simple applications that do not require the transfer of large amounts of data, as well as for use in wireless subscriber access systems Wireless Local Loop (WLL). The Wireless Local Loop system is a terrestrial radio communication system that implements fixed or limited-mobile wireless access for subscribers to a public switched telephone network switch.

Many countries are dissatisfied with the demand for telephone services. Russia as a whole has an underdeveloped telecommunications structure: there are only 19 subscriber lines per 100 inhabitants. For comparison, in America this number is several times higher. Therefore, wireless technologies are increasingly being used to provide new subscribers with high-quality telephone services at reasonable prices, especially in regions where the wired telephone infrastructure is overloaded, outdated or does not exist. Local Loop cordless telephones allow landline operators to expand their networks and provide mobile operators with services that meet the needs of subscribers.

WISMO Quik Q2400 is a two-channel GSM module (E-GSM-900/1800 MHz), which is ideal for use in WLL, as well as for simple point-to-point applications. Developed by WAVECOM based on a reliable GSM protocol stack, the Q2400 module guarantees trouble-free operation in GSM networks.

The dimensions of the module 58.4 x 32.2 mm allow it to be integrated into small devices. The module supports such functions as battery power, calendar and real-time clock, echo cancellation and noise reduction, color display, full stack of GSM protocols. The 60-pin connector on the Q2400 Series combines the following outputs: power supply, SIM card, serial interface, audio, keyboard, LCD.

To simplify the development process, WAVECOM offers a unique reference design package, which includes the Q2400 module, a full package of recommendations for developing hardware and a description of the software features. Using the open reprogrammable OpenAT platform, users are able to create flexible, cost-effective solutions for specific tasks and embed them in the Flash memory of the module. The WISMO Quik Q2400 module is an economical and reliable solution for Russian consumers.

WAVECOM modems are available not only in the form of modules, but also in the form of finished products completely ready to work in the case. These are already models of the Integra and Fastrack series that are well known to Russian developers. Fastrack models are Plug & Play devices. Fastrack modems developed on the basis of the WISMO Quick module are equipped with an LED indicator, an antenna switch, an RS-232 driver, a power supply with advanced features, which allows you to connect the modem directly to the COM port of a personal computer. For more than 5 years, the Fastrack series modems have demonstrated stable and reliable operation in wireless networks around the world.

To replace the popular Fastrack M12XX models, WAVECOM has proposed the new miniature Fastrack M1306B model. (Fig. 3) The dimensions of the terminal are only 73 x 54 x 25 mm, which is 25 mm smaller than the models of the previous generation. The weight of the device is 82 g. The modem is housed in a sealed, shockproof metal case, which allows it to be used in harsh industrial conditions. In addition to the new form, new features are added to the device. Fastrack М1306В is equipped with 2 general-purpose inputs / outputs, which can be multiplexed with an I2C bus for connecting external devices. Also, the modem implements the property of automatic power off by applying a signal to the serial port. This property makes it possible to program the energy conservation mode, which is especially important for solutions that use an external battery.
