Telit claims smallest 2G module with integrated A-GPS receiver

Telit Wireless Solutions has introduced the GE864-GPS quad band GSM/GPRS M2M module with embedded GPS receiver in a compact BGA form factor.

The combined product is suitable for integrated positioning in automotive, tracking or security applications requiring 2G network connectivity in a small footprint.

The module has the same form factor and is pin-to-pin compatible with the company’s GE864 family; Telit claims it is the smallest GSM/GPRS module in the market with full 48-channels A-GPS functionality. It combines the firm’s GSM/GPRS core technology with the Sirfstar IV high sensitivity single-chip A-GPS receiver.

The assisted GPS receiver has a power management function, which lets it maintain hot start capability at low energy consumption, while providing a position resolution accuracy of less than 2.5m. Moreover, it supports satellite based augmentation systems, such as Waas, Egnos, MSas and Gagan.

With a dedicated power supply circuit, the GPS chipset can work independently from the GSM chipset and still operates when the cellular part is in power saving mode or switched off. This function is helpful for battery-operated set-ups that activate the communications function only upon triggering events such as, for example, location changes.

“The GE864-GPS is a prime example for the advantages of Telit’s proven family concept,” said Dominikus Hierl, chief marketing officer at Telit Communications.

“Clients who have been using the GE864-Quad V2 in their solutions can now incorporate GPS functionality without changing the application design. This helps them to reduce development costs and time to market.”

The GPS receiver is equipped with a flash-based memory, so the firmware can be upgraded. The ball-grid-array package (30 by 30 by 2.9 mm) allows the end application to have a low profile and small overall dimensions. Since connectors are eliminated, the cost is reduced.

Features include embedded Python script interpreter, jamming detection, integrated TCP/IP protocol stack and Easy Scan.

All Telit modules support over-the-air firmware update by Premium Fota Management. By embedding Redbend’s VCurrent agent, Telit can update its products by transmitting only a delta file, which represents the difference between one firmware version and another. Fota service is available for the GSM firmware and will be available in the future for the GPS firmware as well.
