The recent mobile networks are indicated with 3G (third generation) and 4G (fourth generation). But who can remember the terms ATF-1, Greenpoint and GSM remember. Probably the generation that still knows what LPs and cassettes. Were the aforementioned networks primarily used for voice, GPRS, EDGE and UMTS packet services were mainly used. But what about 3G and 4G?
Actually it is not until the third generation marked "3G" and used for the sequel "4G".
It is the designation for mobile phone standards and technology.
The International Telecommunications Union (ITU) that standards-family management.
3G or third generation
3G gives:
- A wider range of services,
- Advanced capabilities
- Higher network speed (theoretically 10.5 megabits per second Mb / s)
this speed corresponds to DSL and cable internet.
Among other things, this will include:
- Voice over IP (VoIP)
- Video conferencing
- Mobile broadband
the released frequencies for these services is the 230 MHz spectrum.
This spectrum shows the following speeds, depending on whether you are stationary or moving:
144 kbit / s for fast movement, as in a car or train.
384 kbit / s at walking speed or bicycle
2 Mbit / s at standstill, for instance at home or office.
The highlight of 3G in 2010, which also called pre-3.9G 4G called-was used.
4G or fourth generation
As with 3G, 4G is an indication of fourth generation, 4G is the successor to 3G.
The speed of 4G is again significantly improved with respect to the precursor means a factor of 10!
100 Mbit / s for fast movement, as in a car or train.
1000 Mbit / s when stationary or walking
4G in the coming months and years strong stand. It is expected that this speed except for telephony (smartphones) to other users (eg laptops) are popular. At present, even the stringent standards for radiation limit the extensive rollout of 4G. First you will need more clarity about the safety.
In the Netherlands KPN takes the lead in the provision of 4G in Amsterdam and a number of other areas Randstad. The frequency range used by KPN prevented use on Apple products. Other providers are in both frequency ranges offer 4 G: 800 MHz and 1800 MHz. For Apple fans will have to wait.
4G in the USA almost anywhere already offered.
