  Today 2.4 GHz based wireless sensor networks are increasing at a tremendous
pace, and are seen in widespread applications. Product innovation and support
by many vendors in 2.4 GHz makes it a preferred choice, but the networks are
prone to issues like interference, and range issues. On the other hand, the
less popular 868 MHz in the ISM band has not seen significant usage. In this
paper we explore the use of 868 MHz channel to implement a wireless sensor
network, and study the efficacy of this channel
