On October 4, 1957, the first artificial satellite. It was about the Sputnik I. was sent from the Soviet Union out of Earth orbit. This milestone was the kickoff for the beginning of the space age. In it, the competition between world powers to create the best technology, laid the foundations for the devices we know today as everyday.
Since then, more than 2,500 satellites have been launched. Many of them today work mainly for telecommunications. Mobile calls, location, maps as we know them today, among other things, would not exist.
In this post we will deal with one of the satellite technologies that can connect a person to the Internetfrom anywhere on earth.
What is BGAN technology and what is it used for in telecommunications?
As indicated by its acronym in English (Broadband Global Area Network) it is a global broadband area. Namely, It is a satellite communication system. It is used to transmit and receive data through a small portable device, directly to the satellite. No need for external antenna.
BGAN can transmit at speed rates of up to 492 Kbps, guaranteeing a minimum of 256 Kbps. Allows you to connect to Internetuse services of Messenger service, video calls, download and send files simultaneously. This is possible thanks to the fact that the company uses Inmarsat I-4 civil communication satellites (the most advanced to date).
As for the terminal for use, it is not bigger or heavier than a standard laptop. In addition, it offers connection , USB and LAN if you want to link another device.
The main function of this technology is to connect people who are in remote parts of the planet (with the exception of the poles, given the terrestrial shape). It is designed for people who move from one place to another. Unlike VSAT technology that requires an antenna that is difficult to install.
What are the main characteristics of BGAN Internet connections?
Within the functions of this communication system, we can establish the following basic characteristics:
- Upload and download speed up to 492kbit per second.
- Latency from 1 to 1.5 seconds for background IP services.
- 800ms per second for streaming services.
- Compatibility with the main products of VPN.
- Costs for megabyte €7.50 (varies slightly depending on the contracted plan).
- calls voice by 1 euro per minute.
- Easy setup (no need to be an expert).
- Does not require precise positioning. Unlike other systems with satellite dish.
- does not suffer Due to changes in the conditions of the climateeg rainy or cloudy days.
How does BGAN improve on other satellite Internet connections?
There are multiple Internet services via satellite. VSAT, iDirect, Tooway, among others. In this case, we will mention the comparative advantages of BGAN over the others:
- Easy handling of the terminal. Since it does not require locating or directing it as accurately as other systems. That is, it does not need to focus on precise points in the sky.
- Uses band type L. Which facilitates its connection to the satellite in rainy or even snowy weather.
- Recommended for mobile use. It is the best option for use on a trip, eventual video transmissions, rescue teams, use at sea, etc.
- Designed for individual users. Although a VSAT connection can be cheaper if you consider that several people can connect to it. For casual use, BGAN is ideal, because you can only pay for the data you use.
- It’s cheaper. The equipment necessary for the connection is lower in price compared to other systems. This is because it does not require satellite dishes, professionals for installation, etc.
- Coverage area. We are talking about the entire globe.
- Portability. The terminals are similar in size to any laptop. In addition, they have a rechargeable battery, which is indicated for use in places without connection to the electrical network.
BGAN types What are the main services of these connections?
The Inmarsat satellite company offers different types of service for land mobile terminals. These are:
Standard
This service offers the possibility of connecting Internet, phone, SMS, Fax and video calls. It is designed for all terminal models, except for the one used for M2M.
standard +
Launched in 2017, it offers a plus compared to the previous one. You can access a unlimited internet use, in addition to the possibilities of its predecessor. 5MB per month is authorized, and in case of exceeding that transfer, it is paid later.
M2M
It means “machine to machine” Machine to machine. This is an optimized service for cases in which a transfer minimum. For example, control and monitoring devices. It is only available for the terminal model Hughes 9502 BGAN.
Link
Main competence of VSAT systems. It is suitable for low mobility needs. Or temporary establishment on a site. It offers up to 30 GB of monthly transfer and in some regions, unlimited. Can only be used with one device BGAN Class 1. They can be moved up to 4 times a year with an extra cost for each move.
Importance of BGAN What are the sectors that need this type of connection the most?
Any person or institution that has financial means to purchase this equipment and service can do so. Although it would be a waste if you have a ground connection, since it is cheaper and more stable. However, there are cases when such a tool is ideal. Let’s see them:
- Media. It can be used for live broadcasts in areas without traditional coverage. Even war or wildlife photographers can send their shots to the publisher in real time.
- expedition transport. Especially the military, can count on the ability to transmit data immediately from anywhere in the world.
- Emergency services. We are not only talking about rescuers, BGAN is ideal for seismic prevention devices or other natural disasters.
- engineering companies. For example, mines, since they are established for a long time in one place, but at the same time not permanently.
