Low-earth orbit satellites, although less economical, generally offer better service. Rather than the radio signals needing to travel between a temperate or arctic zone and a satellite 22,000 miles above the equator, the signals must only travel between a nearer satellite which is about 17,000 miles above (which only takes about 50 milliseconds). Additionally, LEO networks require less transmission power, which enables the phone batteries to power their devices longer per charge than their counterparts. This also means that relatively small antennas may be used with LEO networks. This means that these phones can be constructed with a size roughly equal to [[smartphone]]s.<ref name="howstuffworks 3">http://electronics.howstuffworks.com/gadgets/travel/satellite-phone2.htm</ref> <br />

However, LEO networks use smaller, less powerful satellites, since each one has fewer requirements. They can only communicate at a rate of 9,600 bits per second, much slower than geosynchronous systems. Although much larger antennas are required for geosynchronous systems, they can communicate at a much greater rate, since each satellite is much more powerful.<ref name="howstuffworks 3"/>
