Qualcomm has announced some 4G LTE modems. The company has launched Qualcomm Snapdragon X12 LTE modem (9×40) and Qualcomm Snapdragon X5 LTE modem (9×28).
The Snapdragon X12 LTE modem (9×40) is designed to enable auto manufacturers to develop next-generation systems with advanced telematics and connected infotainment features. It supports greater coverage at download speeds up to Category 10 (up to 450 Mbps in the downlink and 100 Mbps in the uplink). The Snapdragon X5 LTE modem is designed to enable automakers to broadly deploy LTE in all cars at download speeds up to Category 4 (up to 150 Mbps in the downlink and 50 Mbps in the uplink).
In addition, these modems support all major 3G/2G cellular standards and a 1 GHz processor with Linux and built-in software for key global regulatory mandates like EU eCall and ERA Glonass. The Snapdragon X12 LTE modem supports Carrier Aggregation (CA) across global TDD and FDD radio frequency bands while the Snapdragon X5 LTE modem supports Category 4 across global TDD and FDD radio frequency bands.
“With smartphone connectivity setting the pace for advanced features, consumers expect the same experience from all other connected devices, including their car. Qualcomm Technologies already supports first-generation LTE connected cars with major automakers. We are now pressing ahead with the vision of LTE for all automakers, cars, geographies and models with the leading performance of the X12 and the leading value of the X5.”
said Kanwalinder Singh, senior vice president of business development for Qualcomm Technologies, Inc.
Both the Snapdragon X12 and X5 LTE modems support the major cellular standards, including LTE, DC-HSPA, EVDO, CDMA 1x, GSM and TD-SCDMA, support the major RF bands and band combinations. Additionally, the modems feature integrated support for VoLTE and key new automotive regulatory safety features such as EU eCall and ERA Glonass. In both chipsets, a Cortex A7 is integrated to provide bill of materials (BOM) cost savings for hosting automotive telematics applications.
Snapdragon X12 LTE and X5 LTE modems inter-work with QCA6574A, a dual-stream 802.11ac Wi-Fi and Bluetooth 4.1 chipset, to support in-car Wi-Fi hotspot functions and Bluetooth profiles, and the QCA6584, which also supports DSRC (dedicated short-range communications). Both the modems will also be pre-integrated with Qualcomm Technologies’ automotive-grade Snapdragon 602A infotainment processor. Speeds range from 150Mbps down and 50Mbps up with the X5 to 450Mbps down and 100Mbps up with the X12.
