DASH7, an open source wireless sensor networking standard, competes with Zigbee (900MHz/2.4GHz), Z-Wave (900 MHz), Bluetooth (2.4GHz), WiFi (2.4/5 GHz), and Low Power UWB for machine to machine communications, but features multi-kilometer range, excellent penetration of walls, floors, and water, operates on extremely low power and features multi-year battery life with a maximum bitrate of 200kbps.
Operating in the license-free 433.92 MHz spectrum, DASH7 offers multi-kilometer range, multi-year battery life, sensor and security support, as well as tag-to-tag communications, achieved through ad hoc-synchronized communications. The new protocol is built on the IEC 18000-7 standard and provides seamless interoperability.
“A distinct capability of the protocol provides for both infrastructure to endpoints (RFID tags) and endpoint-to-endpoint communications, while operating from a battery and maintaining low power operation”, said Michael Andre, chairman of the Dash7 Alliance.
Near Field Communication is a short-range wireless technology that enables the exchange of data between devices over about a 10 centimeter (around 4 inches) distance using globally available and unlicensed 13.56 MHz, with a bandwidth of 14 kHz.
Contactless payment systems use RFID for making secure payments. Phones featuring Near Field Communications combine the interface of a smartcard and a reader into a single device. They have been used in Asia for many years.
According to the independent wireless analyst firm Berg Insight, the number of cellular network connections worldwide used for M2M communication was 47.7 million in 2008. The company forecasts that the number of M2M connections will grow to 187 million by 2014.
The risk inside a credit card with RF-ID may be real, according to this report. A tinfoil hat for your credit cards might be a good idea.
