Dash7 is a new wireless networking scheme and appears to be gaining traction. The international organization of standardization first ratified the standard behind DASH7in 2004.The less power drawing feature make it especially appropriate for such things as radio-frequency tags, which may work for years without any external power source. If the system doesn't need high data rate can use Dash7. Dash7 tags are active, meaning that they make use of small batteries instead. It doesn't need to transmit high power levels and consequently can be manufactured inexpensively. DASH7 operates at around 433megahertz.
