Product Description
3G-AA Click Board™ is a versatile cellular network communication solution, featuring the compact 3G UMTS/HSPA Quectel UG95 module. This module features a full set of options for the cellular networking and communication, such as the network indication, embedded TCP/UDP stack, HTTP/HTTPS stack, full GSM/GPRS/EDGE implementation, UMTS/HSDPA/HSUPA protocol implementation and more.3G-EA Click Board™ features data-rates of 7.2 Mb/s (downlink) and 5.76 Mb/s (uplink) in HSPA mode. on-board 16-bit audio CODEC IC adds high-quality voice communication capability.
3G-AA Click Board™ is qualified to work at North American UTMS frequency bands. A wide range of Internet protocols and connectivity options, as well as the Quectels simple AT command interface via the UART bus, make this Click Board™ perfectly suited for a wide range of M2M applications, such as mobile Internet terminals, automatic meter reading (AMR), remote monitoring automation and control (RMAC), surveillance and security, road pricing, asset tracking, fleet management, anti-theft systems, point of sales (PoS) terminals, and similar applications which rely on a cellular network connection.
How Does it Work?
As previously mentioned, 3G-AA Click Board™ is equipped with the compact dual-band 3G UMTS/HSPA Quectel UG95 module, from Quectel Wireless Solutions Company. This Click Board™ is compliant with the North American UTMS frequency bands. For the European and Australian region, please visit the 3G-EA product page. A complete list of supported frequencies, along with other relevant info about the module itself can be found in the Quectel UG95 module datasheet. This device is the main component of the Click Board™ and it consists of a number of internal blocks or sections, such as antenna switching section, RF transceiver section, memory, power management, and most importantly - the cellular baseband processor. This section contains the logic necessary for managing the other sections and provides the interface to the host MCU. This interface consists of several lines used to report the device and the network status, SIM card interface lines, UART interface lines, USB interface lines, I2C bus lines, device control lines, and PCM bus lines. These lines are routed to the respective elements of the Click Board™.
