Wireless mesh networks have seen phenomenal growth due to their unique ability to self-heal and self-organize, while providing robust and reliable solutions for applications that require low data rate, long battery life, high reliability and interoperability between multiple OEM vendors.

The growth of wireless mesh networks is also tied to the emergence of low cost open source ZigBee communication protocols. Powering ZigBee wireless sensors is most challenging in hard-to-access locations where hardwired AC power is either impossible or not cost effective. For applications that require self-contained, battery powered solutions, Tadiran bobbin-type lithium thionyl chloride batteries are the preferred choice due to their proven ability to deliver 20+ years service life, high energy density (1420 Wh/I), high capacity, and their ability to withstand extreme temperatures (-55ºC to 125ºC). Tadiran also offers PulsesPlus batteries for high current pulse requirements.

While wireless mesh networks are a relatively new phenomenon, wireless sensor networks have been in use since the 1980s, initially found in automatic meter reading (AMR) devices for the utility industry. In 1984, Hexagram (now Aclara) began powering its AMR devices with Tadiran high energy lithium thionyl chloride batteries. A quarter century later, virtually all of these devices continue to operate trouble-free on their original batteries.

Based upon ongoing improvements in the design of Tadiran batteries, coupled with low power ZigBee wireless RF communication protocols, today’s advanced wireless mesh network sensors can easily achieve 20+ year service life, depending on yearly watt/hour requirements and environmental factors.

When designing sensors for use in a wireless mesh network, accept nothing less than Tadiran battery, the only one proven to last 25 years in a wireless sensor application.
