Texas Instruments Focuses on Nano Power Energy Harvesting

Texas Instruments introduced its next generation of power management integrated circuits (ICs) for energy harvesting, potentially opening the door for self-powered devices, such as wireless sensors in Smartgrid, industrial, security, medical, agriculture, and structural monitoring applications.


TI said its new, highly efficient boost charger for nano (ultra low) power energy harvesting can manage the microwatts to milliwatts of power generated from a number of sources, such as solar, thermoelectric, electromagnetic and vibration, and store the extracted energy in various storage elements, including Li-ion batteries and super capacitors. The new device also includes circuitry to protect the energy storage element from over voltage and under voltage conditions and to kick-start the system when the battery is deeply discharged.


TI calculates that in a solar panel powering a handheld device that is operating in indoor light conditions, for example, the new boost charger increases the usable harvested energy by 30 to 70 percent compared to a linear regulator.


"Wireless sensor networks have been limited in their penetration due to the cost associated with maintaining and replacing the batteries within sensor nodes," said Sami Kiriaki, senior vice president over TI's Power Management business. "With the bq25504 boost charger, the nodes can power autonomously, which can reduce the operating cost and thereby make ultra low-power wireless sensor networks cost-effective in more applications, such as industrial monitoring of hazardous or restricted areas." http://www.ti.com/

ABI Research: 80 Million LTE Connections Worldwide by 2013

ABI Research is predicting80 million LTE connections globally by the end of 2013, including both FD-LTE and TD-LTE. The research firm noted that all three operators in Saudi Arabia recently lit up TD-LTE networks using 2.5 GHz licensed spectrum meant for WiMAX and plan to extend their coverage nationwide. While the Saudi operators have conducted FD-LTE trials for over a year with various vendors, the reason behind the TD-LTE network choice is primarily due to unavailable paired spectrum. They are waiting on the regulator to release new spectrum, since preferred frequency is currently used for military purposes.


“The issue of insufficient spectrum echoes across various markets and is especially evident in developing regions as regulators are a bit slow in reacting to market needs,�? notes Philip Solis, research director, mobile networks. Many operators are looking into the option of spectrum re-farming. While the preferred spectrums are usually 2.6 GHz or 700 MHz, players such as Poland's Aero2 and Singapore's MobileOne have successfully deployed FD-LTE on 1.8 GHz, which was slated for 3G usage. Aero2 has deployed TD-LTE on 2.5 GHz band. http://www.abiresearch.com
