Differences between Cell Phones and Satellite Phones |
Posted: April 1, 2015 |
Although most people know about the existence of satellite phones, many do not actually know anything about how they work or how they look like. In most situations those that use them are the same that also have satellite television but various other uses can exist. To put it as simple as possible, satellite phones like those available at Ashbury SatCom, will connect directly to a satellite that orbits the Earth. Then, the signal will be directed towards the other destination needed. The first use of a communication satellite dates back from 1958. Ever since that year, technology evolved and you can use the satellite phones to be able to have a direct line of contact with whoever you want from wherever you may be. The truth is that satellite phones are expensive but you will definitely want to use it in various cases. Satellite phones first appeared during the nineties and although sales were not at all good then, now everything is different. The first difference that should be mentioned when comparing the regular mobile phone with the satellite phone is the fact that a satellite phone will transmit a signal to the closest outer space satellite. Regular mobile phones will transmit signals to earth bound cellular networks. A satellite phone will use LEOs in order to form networks that offer a global coverage. There are also some satellite phones that are using geostationary orbiting satellites that are located over 35,000 kilometers from the surface of the Earth. LEO satellites are located quite close to the surface so that voice clarity is as high as possible. What is interesting with the satellite phones is that they work through a direct connection that is established to the satellite. In the event that there is no direct line of sight, the connection cannot be established and this basically means that you will not be able to make a call. With this in mind, the regular use of the satellite based devices in houses or in any location that does not have that direct line of sight. This does include apartments and staying near really tall buildings. As you can easily notice, there are situations in which the satellite phone can be really useful but there are also situations in which you will just want to use a regular mobile phone. Everything basically depends on the regular use that you have for the device. In the event that you decide you should buy a satellite phone, do conduct a good research since you do need to be 100% sure that you choose something that is really good. Unfortunately, most people from around the world make mistakes and only buy gadgets that they think they need when the truth is that they do not actually need them. The quality of the satellite phone that you choose will have a huge impact on how well the device will work. It is really important that you choose something that is suitable, only after you read reviews written by professionals.
