|
A8500 is one of the smallest Quad-band GSM/GPRS modules in LCC packaging with the compact size of 19.5 × 25.5 × 2.3mm, ultra low power consumption and extended temperature range.
With surface mounted technology, the low profile and small size of LCC package makes A8500 easily embedded into the low-volume applications and ensures the reliable connectivity with the applications. This kind of package is ideally suited for large-scale manufacturing which has the strict requirements for cost and efficiency.
Built-in FOTA technology allows A8500 to the firmware remotely. Additional features such as integrated TCP/IP protocol stack, serial multiplexer and enhanced AT commands guarantee fast and reliable transmission of data, voice, SMS via GSM/GPRS network and extend the functionality of the application without adding cost.
Its tiny size and ultra low power consumption makes A8500 a very cost effective and feature-rich platform that is quite suitable for a wide range of M2M applications such as VTS, Industry PDA, Personal Tracking, Wireless POS, Smart Metering and many other M2M applications. |
