On October 4, 1957, the first artificial satellite. It was about Sputnik I. It was sent from the Soviet Union out of Earth orbit. This milestone was the kick-start for the beginning of the space age. In it the competition between world powers to create the best technology, laid the foundation for the devices that we know today as everyday.
Since then, more than 2,500 satellites have been launched. Many of them today operate primarily for telecommunications. Mobile calls, location GpsMaps as we know them today, among other things, would not exist.
In this post we will discuss one of the satellite technologies that can connect a person to the Internet, from any part of the earth.
What is BGAN technology and what is it for in telecommunications?
As indicated by its acronym in English (Broadband Global Area Network) it is a global broadband area. That is to say, is a satellite communication connection system. It serves to transmit and receive data through a small portable device, directly to the satellite. Without the need for external antenna.
BGAN can transmit at rates of up to 492 Kbps, guaranteeing a minimum of 256 Kbps. Lets connect to Internet, use services of Messenger service, video calls, download and send files simultaneously. This is possible because the company uses Inmarsat I-4 civil communication satellites (the most advanced so far).
As for the terminal of use, it is not bigger or heavier than a standard laptop. In addition, it offers connection Wifi, Bluetooth, 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 (except for the poles, given the terrestrial form). It is designed for people who move from one place to another. Unlike VSAT technology, which requires an antenna that is difficult to install.
What are the main characteristics of Internet connections by BGAN?
Within the functions of this communication system, we can establish the following basic characteristics:
- Up and down 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 according to 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 weatherFor example, rain or cloudy days.
How does BGAN improve other Internet connections via satellite?
There are multiple Internet services via satellite. VSAT, iDirect, Tooway, among others. We will mention in this case 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, you don't need to focus on precise points in the sky.
- Uses band type L. Which facilitates its connection to the satellite with rainy or even snowy climates.
- Recommended for mobile use. It is the best option for use on a trip, eventual video transmissions, rescue equipment, use at sea, etc.
- Designed for individual users. Although a VSAT connection can be cheaper considering that several people can connect to it. For eventual use, BGAN is ideal because only the data used can be paid for.
- It's cheaper. The equipment necessary for 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 talk 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 electricity grid.
Types of BGAN What are the main services of these connections?
The satellite company Inmarsat offers different types of service for land mobile terminals. These are:
Standard
This service offers the possibility of connection Internet, phone, SMS, Fax and video calls. They are intended for all terminal models, except for the one used for M2M.
Standard +
Launched in 2017, it offers a plus over the previous one. You can access a unlimited use of the Internet, in addition to the possibilities of its predecessor. 5MB per month is authorized, and if this transfer is exceeded, it will be paid later.
M2M
It means "machine to machineMachine to machine. It is a service optimized for cases where a minimum transfer. For example, control and monitoring devices. Only available for terminal model Hughes 9502 BGAN.
Link
Main competence of VSAT systems. It is suitable for low mobility needs. Or of temporary establishment in a place. 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 movement.
Importance of BGAN What are the sectors that need this type of connection the most?
Any person or institution that has the economic means to acquire this equipment and service can do it. Although it would be a waste if you have a ground connection, since it is more economical and stable. However, there are cases where such a tool is ideal. Let's see them:
- Media. Can be used for live broadcasts in areas without traditional coverage. Even war or wildlife photographers can submit their captures in real time to the publisher.
- Expedition transport. Especially the military, you 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 firms. For example, mines, since they are established for a long time in one place, but at the same time not permanently.
