This is a 2 dBi omni-directional 900 MHz dipole antenna with an RP-SMA plug. Omni-directional antennas radiate equally well in all directions and are best used to spread a signal uniformly over some area. Unlike a directional or semi-directional antenna, an ideal omni-directional antenna does not favor any direction in particular. For a general purpose application, omni-directional antennas are usually the antenna of choice and directional or semi-directional antennas are used when the application and node locations are well defined. The dBi rating of an antenna specifies the amount of gain the antenna has in a particular direction. An antenna gain of 0dBi specifies an antenna that radiates

This is the AT86RF212 900 MHz radio peripheral v1.1 for the FreakLabs WSN rapid prototyping MCU boards. It supports the license-free 915 MHz North American band, 868 MHz European band, and the 780 MHz Chinese band. It's supported by the Chibi software stack and the default band can be set in the stack. 900 MHz radios are often preferable to 2.4 GHz radios because there is less crowding in the frequency band and lower frequencies suffer less path loss and attenuation. Hence the range will be greater for the same amount of power between a 900 MHz radio and 2.4 GHz radio. This board has a FreakLabs universal serial connector that can connect to any FreakLabs MCU board and also comes with

900 MHz, 802.15.4, High Power Radio Peripheral

Price: $45.00

The FreakLabs FL-AT86RF212-CC1190-DEV 900 MHz modular radio board is designed to be an easy way to rapidly prototype and evaluate usage of high powered radios for wireless sensor networks. It comes with the Atmel AT86RF212 900 MHz radio which conforms to the IEEE 802.15.4 wireless protocol. It also sports a high power front end transmit amplifier and low noise receive amplifier to improve the communications range of the radio. This board was originally designed to evaluate high power radios for research work in environmental monitoring applications. In a remote location, a wireless sensor network often consists of a localized sensor network to collect data and a long distance link to a
