Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

wire.less.dk "is a highly specialized independent team of experts in wireless and internet technology, working with business customers as well as non-profit projects, e.g. community networks and ICT initiatives for the developing world. " They offer the autonokit: "the idea of the autonokit is, to bring together affordable, available wireless and solar standard technology, (hardware and software) test and optimize it for usage under adverse mobile conditions in order to produce a kit for inexpensive and autonomous internet access.

Low power, low datarate: chip aims for medical implants: "The AMIS-52100 transceiver is the latest member of the low-datarate ASTRIC (application specific transmit and receive IC) product family from AMI Semiconductor. The new chip appeals to sub-500MHz-band wireless applications that require clock and data recovery, and is particularly suited to medical implantable devices. Targeting the FDA's Medical Implantable Communications Systems (MICS) standard and European standards for ultra-low-power active medical implants (ULP-AMIs), the device is optimised for operation in the 402-405MHz frequency band. The band outlines a specific radio frequency range for two-way communication between medical devices to retrieve important information about a patient's status with improved data transfer rates... The AMIS-52100 will be priced at $1.95 in quantities of 50 thousand units, assuming a 20-lead SSOP. Samples and evaluation kits will be available in March 2004. The product is immediately available for ASIC integration. " 

Markets "for things like heart pacemarkers and defibrillators is $5.1 billion, growing 10% per year, while that for hearing aids is $2.6 billion. Some of the best solutions now available for grabbing a share of that market involve "low-power, low-data-rate wireless technology" based on "a stand-alone transceiver IC."

Solar wireless road devices: "There are "wireless applications that are also emerging that aren’t personal, but may eventually constitute as important a market—self-powered, embedded, networked, wireless devices. Like the ones that SPOT Devices Inc is bringing to market. ..Road Spot, their product, integrates high-efficiency solar cells with ultra-bright light emitting diodes (LEDs) to create a completely self-contained inroad light that flashes brightly upon activation. Unlike existing inroad lighting solutions, Road Spots install easily without trenching or saw-cutting road surfaces. Furthermore, since Road Spots do not need wiring or external power, they can be used in a multitude of locations. All of which makes them dramatically less costly than existing solutions. .. provide pedestrians about to enter a crosswalk with warning of [They can] approaching vehicles, and can give motorists advanced warning for road crossings, stop lights..

Road Spots communicate with a controller, and with each other, over 2.4GHz, which makes them easy to control, customize, and upgrade—without ever having to dig up the roadway. Even more importantly, wireless communication provides alerts about battery changes or replacement, as well as providing a copious database of operational statistics, such as how often each unit flashes, and how traffic varies by day and by time of time—data that’s otherwise extremely expensive to obtain."

Once on the net, why not these apps: "as part of automated farming solutions, for municipal airports who are currently limited to daylight hours of operation because they can’t afford to install runway lighting, concert venue traffic control, automated parking meter payment, and many more. Not to mention many potential military and homeland security and surveillance applications.""
