Satellite Communication


While the world has made many firsts with satellites, handheld terminals have evolved from being chunky and laptop-sized to becoming sleek and smart devices. These devices are not exclusive to governments, marines, and emergency services anymore but are available to the casual user for business or safety purposes. The wide acceptance of smartphones, dramatic improvements in user experience and access to large app stores have significantly influenced the design and development of satellite terminals that include advanced features such as hotspot.

Client challenges

The satellite communication industry is moving from smaller data to higher data and adding alternatives like fixed data to mobility based data. Unlike terrestrial handsets, satellite phones cater to a niche and exclusive market. With low demand volumes, semiconductor companies and terrestrial networks do not invest heavily in satellite communication. Some of the other challenges include working on technology for handsets that provide more data rate at low bandwidth and low latency. Another challenge that satellite communication terminal manufacturers are grappling with is expecting the device to have a rugged lifespan of four to six years with less cost of service and advanced power management to provide a long battery life.
