WAVECOM: new developments in the wireless market

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

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

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

This year, the company WAVECOM has developed and launched the production of new innovative wireless devices. One of these devices is the combined WISMO Quik Q2501 GSM / GPRS / GPS module, which is designed for use 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 extended working temperature range –35 ... + 85 ° С allows the use of Q2501 series modems in adverse industrial conditions.

WISMO Quik Q2501 is a dual-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 and 4 Mbit SRAM. The built-in 16-channel NMEA-0183 GPS receiver provides high positioning accuracy. Flexible operation modes allow using GSM / GPRS and GPS functions both independently of each other and jointly. Offline operation provides direct access to GPS data, regardless of the ability to connect to the GSM network; GSM Master mode associates GPS data with GSM. The module is controlled using a set of 550 AT commands; WAVECOM has developed a special set of AT commands to control the GPS receiver.

The new development contains built-in TCP / IP-stack, which allows you to establish connections such as TCP / IP, POP3 and SMTP without the use of additional hardware and software. The module provides the ability to embed additional user applications in the module’s flash memory.

The 80-pin connector of the Q2501 series modules includes the following outputs: 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 pulse. The appearance of the WISMO Quik 2501 is shown in fig. one.

A new development, announced by WAVECOM in 2004, was also the Q2400 module, complementing 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 Local Loop (WLL) subscriber access systems. The Wireless Local Loop system is a terrestrial radio communication system that provides fixed or limited-mobile wireless subscriber access to a public switched telephone network switch.

Many countries are not satisfied 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 larger. Therefore, wireless technologies are increasingly 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 phones allow landline operators to expand their networks, and cellular operators to deliver services that meet the needs of subscribers.

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

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

To simplify the development process, WAVECOM offers a unique developer kit Reference Design Package, which includes the Q2400 module, a complete package of recommendations for the development of hardware and a description of software features. Using the open, reprogrammable OpenAT platform, users have the opportunity to create flexible, cost-effective solutions for specific tasks and embed them into the flash memory of the module. WISMO Quik Q2400 module is an economical and reliable solution for Russian consumers.

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

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