1XRTT

Smaller, Cost Effective Kyocera 300 and Kyocera 1xD Modules Bolster Suite of Kyocera M2M Products with Advanced Location Capabilities

Kyocera Wireless Corp. has announced the launch of two new compact and cost-effective machine-to-machine modules for CDMA 1xRTT networks. Based on a smaller footprint for more widespread integration, the Kyocera 300 Module provides integrated voice, data and autonomous global positioning system (GPS) capabilities, while the Kyocera 1xD Module debuts as a low cost CDMA data-only module platform for telemetry applications. Leveraging Kyocera's expertise from its award-winning Kyocera 200 Module, both new modules offer an expanded feature set, improved cost efficiencies and a backwards-compatible software interface for simplified porting.

CDMA2000 1x

CDMA2000 1x, the core CDMA2000 wireless air interface standard, is known by many terms: 1x, 1xRTT, IS-2000, CDMA2000 1X, 1X, and cdma2000 (lowercase). The designation "1xRTT" (1 times Radio Transmission Technology) is used to identify the version of CDMA2000 radio technology that operates in a pair of 1.25-MHz radio channels (one times 1.25 MHz, as opposed to three times 1.25 MHz in 3xRTT). 1xRTT almost doubles voice capacity over IS-95 networks. Although capable of higher data rates, most deployments have limited the peak data rate to 144 kbit/s. While 1xRTT officially qualifies as 3G technology, 1xRTT is considered by some to be a 2.5G (or sometimes 2.75G) technology. This has allowed it to be deployed in 2G spectrum in some countries which limit 3G systems to certain bands.
