Do satellite phones work just like cell phones?
Satellite phones offer many of the same characteristics as cellular phones, including a similar user interface and design. One of the main differences between satellite and cell phones is that the user must put up a larger satellite antenna in order to receive satellite signals. Satellite phones are slightly larger in size than cellular phones because the antenna system required to communicate on the satellite frequencies must be larger than a cellular phone antenna. Another fundamental difference between traditional wireless phones and satellite phones, is that when the phone is in satellite mode, it must be within satellite line-of-sight in order to complete calls. Therefore the mobile handset cannot be used indoors. If satellite phone services are required indoors then an external antenna, allowing line-of-sight between the handset and the satellite.
