| | Telit GSM/GPS Cellular Module Earns North America Certification
| | | Telit Wireless Solutions of Raleigh, North Carolina, announced today that the world?s smallest cellular M2M module, the GE865-QUAD, has earned PTCRB certification, which is required by GSM cellular operators to sell GSM cellular communication products in North America. |
| | Analog Devices Introduces Clock Generator/Synchronizer
| | | Analog Devices has introduced a clock integrated circuit (IC) that enables system designers to use the standard, readily available and free 1-pulse-per-second (pps) signal of GPS satellite transmitters to generate and synchronize clock signals for communications infrastructure equipment. |

 | It's a Wild, Wild Wireless World
| | | Once we understand wireless carriers' structure, operating model, and financial drivers, then plans and prospects for location-based services will become more apparent. Much hinges on a spectrum auction now underway, expected to garner $20 billion. Carriers want LBS to drive a big return on this investment. |

 | Steep-Slope Monitoring
| | | Although GPS is an efficient tool for deformation monitoring, it also is an expensive one for large projects. The authors developed a remote-controlled monitoring system using an electronic switching device for multiple antennas to monitor steep slopes at the Xiaowan hydropower station in China. |

 | PowerDown
| | | Accelerating deployment of location-based services requires reducing the energy-per-fix (EPF) to a minimum, as continuous tracking shortens cell-phone battery life. This article focuses on realizing a low-current RF front end, minimizing RF active time, and developing an intelligent GPS middleware layer to determine whether a low EPF is likely or necessary. |
