Sigfox’s solution requires around 1,000 times less antennas and base stations. The impact on cost is massive – it is 100 times less expensive to build, install and operate. They claim they will have France covered with some 1000 transmission sites. The radio modules embedded in the connected things are tiny and consume 1/50 of the power typically consumed by a cellular M2M module. With such low power consumption batteries could last up to 20 years before recharging or replacement is needed.
