Therefore WT41 provides an ideal solution for developers who want to integrate wireless technology into their design with limited knowledge of and RF technologies. WT41 is optimized for long range applications and since it contains a RF power amplifier, low noise amplifier and a highly efficient chip antenna. With 115 dB radio budget WT41 can reach over 1 km range in line off sight.
