Wireless Sensor Networks

Wireless sensor networks enable long-term environmental monitoring or object tracking through large numbers of unconnected sensor nodes. Because of their large deployment, sensor nodes are expected to be inexpensive to manufacture, small in size, and able operate for many months. While standard consumer AA or coin-style batteries keep sensor nodes active for up to a… Read more »

Ruggedized PDAs

Ruggedized PDAs face a critical shortage of power, particularly at low temperatures. The high pulse power needed for the radio frequency transmissions or new display technologies such as OLED can strain existing batteries. This overload situation quickly lowers voltage and triggers premature shut-down (leaving spare energy in the battery), thus decreasing overall communications time and… Read more »

Mobile Phones

Competitive pressures have driven mobile phone manufacturers to achieve superior power management results – best battery cycle life, standby performance, shortest charge time, smallest size and minimal weight. But mobile phones have high power demands when transmitting data. During transmission, pulse power trains cause battery voltage to sag and efficiency to drop, ultimately shortening the… Read more »

PCMCIA and Compact Flash

Wireless devices capable of delivering 2.5G, 3G, 802.16 and 4G communication services face a critical shortage of power. Pulse transmissions generally exceed the power limitations of wireless modem devices such as PCMCIA, CompactFlash®, USB and mini PCI cards, leading manufacturers to seek components that consume less power and even add batteries to the products.
