If you are a tag designer, check out this new device that replaces the battery, rectification, and regulation functions of the power supply for use with energy harvesting.  This device, when combined with an energy harvesting source like solar cell, or mechanical source can power a tag perpetually.

Sensor networks with hierarchies and their resultant isolation will eventually give way to the notion that all devices should interoperate with the world, through IP protocols. I’ve advocated this trend for some time, but several news items from Sensors magazine reinforce this: Zigbee and IP and Pedigree Releases Oneview
From an architectural perspective, this [...]

Zigbee the much touted wireless sensor network standard has been around a while now. Yet, it’s adoption has been limited. Already several variants and versions have emerged. Any willing vendor can obtain chipsets and protocol stacks and get started right away. But what always makes or breaks a new standard is how well it [...]

You may be interested in this new module from G2 released just last week. It’s the most power efficient, and fully integrated Wifi device available. It’s almost everything you need to build a tag or data collection device except interconnects, sensors, a battery and housing, with all the certifications done. At $22 [...]

In tech adoption, there is a phase where rapid uptake and expansion occur once maturity has begun and the early adopters have proven the concepts. What I’m seeing at this show, is that passive RFID is very close to that phase. However, there are remaining barriers, and they are no longer in the fundamental technology, [...]

There seems to be confusion in the industry about where these descriptions differ.
RFID is a general description of any system that identifies without line if sight. At a cursory glance, RTLS (Real time location System) seems to add a qualitative presentation and timeliness element to data that is collected by RFID.
But ask yourself [...]
