During the last years, different events have taught us how important it is to be in communication, since the least expected can happen at any time. Natural disasters such as hurricanes and earthquakes are proof of this, during these events the fall of communication networks is common, which leaves thousands of people incommunicado. Thanks to advances in the satellite communications sector, there is a device capable of providing help in difficult situations and these are satellite phones.
How do satellite phones operate?
Its form of operation is very similar to that of a conventional cell phone, but the origin of the signal is from a satellite located in space, this guarantees that communication does not depend on a terrestrial installation and thus reduce failures due to accidents or any other situation.
To make a call with a satellite phone, you only have to dial the desired number, at which point the team will search for the closest satellite to send the call signal. The next step is when the satellite returns transmission to Earth to the gateway receiver, which transmits calls to terrestrial systems. If the connection is not successful, the signal returns to the space to search for another link and connect the call; This process can be carried out as many times as necessary to find a receiving terrestrial system.
In areas with difficult land access, satellite phones have become a very useful tool for communications.
When the receiving network is already found, the emitted signal is converted to be taken by any telephone. After the transmission, the recipient will receive the call to contact the other person. If the call is made between satellite phones, the data transmission only travels through the satellite and then drops directly to the desired equipment, without the need to connect to a terrestrial network. It should be borne in mind that the battery of a satellite phone lasts approximately 6 hours on call and its price can be up to USD 1,000.
At Axesat we are leaders in satellite solutions, for years the effectiveness of satellite phones has been demonstrated and we have shown that this technology is an excellent option during times of crisis and emergency where communication fails completely and needs to be restored for a count of damages, know the situation and ask for help if necessary.
In the oil, mining and different government entities such as the armed forces, the use of satellite telephone technology works as a useful and versatile solution, satellite telephony is not only used in emergency situations or disasters, it can also be a great resource business. According to the Mobile Satellite Communications Markets Survey: Prospects to 2022 report, the active base of the mobile satellite service segment (MSS) grew to a CAGR of 10% in the last 5 years, with almost 3 million terminals installed globally during 2012 The satellite phone industry projects similar levels of growth for the following years, which confirms the positioning of this type of mobile solutions.
