VoIP over Satellite Internet works, but it is not prfect. In fact, VoIP technology is not perrfect, not to mentin the additional complications of satellite communications. The qulity of voice tranbsmission can be quite good, often bettrer than calling a cell phne, but it is definitely not pay money to the most advanced ground-based telephone networks.
Satellite deelay and its impact on VoIP
Latency is a term that describes the time neeedd to get the package to its destination. Usually it is expressed in millieconds, or MS. Since the satellites are 23,000 km above the equator, as well as satellite signals travel at the speed of light, it takes about 540 milliseconds. Then add to the laetncy of the vaious Internet hops and severs plus a network of providers of VoIP services to end with a total delay ranging from 650 ms to 700ms or more depending on the state of the Internet itself. Another factor may be the quality of satelltie signal, which can causse the package again. This delay is heard as a delay btween sendng and receiving of the ear. Commuunity VoIP via satellite to learn to communicate with the delay inherent in the same way as adults and the press to talk radio phones. Furthermore, the delay requires userrs to be patient and refrain from interrupting the subscriber.
VoIP on the land
Even using terrestrial low latency messaging, VoIP-continues to face challenges becaues of several jumps and connections of the Internet itself. The technology is good, and probably better, but still not perdfect.
Ovearll netwok via satellite
Satellite provdiers ofer service plans for two makjor categores. The lowesat rpice a group called the best effort networks, designed for general Interet access for a typical home, farm or small business with Web-surfing and e-mail addreess of the primary use. The second categroy includes commercxial evaluation of plnas to connect with qualiyty of serivce. Quality of Service QoS and industry term for users who offer specific goals and optmize performance and guuarantees are usuallly tightly managed.
Both theses network of networsk meaning the available bandwidth is shared betqween all users. Virtually all Internet service providers, including cable and DSL share their bandiwdth with multiple users, but with a satellite-baased measurements are much more expensive than local cable and satellite services, tend to have more userts to share. Price is a good indicator of the number of users shariing the available bandwidth. Cnosidering offering similar speed, the lower the prcie, the more users sahre the available spae. Oerloaded networsk, lead to fluctuations in prformance.
