Making a phone call, send SMS, emails, browse the internet, share photos ... so many things we can do for our laptop through the telephone network operators. But everything is not done at the same speed according to the different operators and the state of the network used.
Orange, Bouygues Telecom, SFR, Free ... some are better than others. And to know the state of its mobile network, just take a look in the corner of the screen of its smartphone. EDGE , or 3G, H and even 4G for the lucky ones ... these small letters determine the connection speed of our laptop. Explanations.
G or GPRS for General Packet Radio Service .
All laptops can connect to the GPRS network: from the small Nokia 3310 that was still a rage a few years ago, to our latest smartphone . Going from 40 kbit / s to 170 kbit / s , the GPRS connection is very slow and you can not do much with it. See your emails or book a train ticket? We forget. With a GPRS connection, you are satisfied with the minimum: call or send an SMS.
E or EDGE for Enhanced Data Rates for GSM Evolution.
EDGE technology is the evolution of GPRS. It is sometimes 3 to 4 times faster than the GPRS network . In EDGE, hope to read his messages or emails if they do not include attachments. But we can not send them.
3G or UMTS for Universal Mobile Telecommunications Systems.
The 3G network's throughput is much higher than the EDGE network, so it offers faster charging. With a 3G , 2 Mbps to 42 Mbps connection, everything that requires the use of the internet is no problem : sending emails, photos, messages, listening to music on online platforms, watching videos . The 3G network is often large enough.
3G or HSDPA for High Speed Downlink Packet Access .
The 3G network offers a connection almost 10 times greater than its previous version, the 3G network. The 3G connection allows you to surf the internet without any problems. With, we can do everything: load applications, emails, photos ...
H .
The H technology is very mobile broadband . By transmitting data on two frequencies, the H allows you to reach speeds up to three times faster than with 3G . With this network, you can load, receive and send everything in seconds.
4G or LTE for Long Term Evolution.
The 4G or LTE network allows (like H ), very mobile broadband . It is the fourth generation of mobile networks. With a throughput of up to 150 Mbps, 4G enables operators to offer their customers a performance that is sometimes 10 times that of the 3G network. Reading and sending emails, chatting on WhatsApp, consulting press articles ... we do everything very quickly with this connection.
4G or LTE-A for Long Term Evolution Advanced.
This is the latest one: the recent evolution of the 4G network. For the time being very little deployed, big operators such as Orange or SFR are developing this ultra-fast connection so that all can be accessed. With a throughput of up to 1 Gb / s, this mobile network is more than excellent. With, one can for example, watch a film of very good quality without being disturbed by a long load.
