For
those of you who like to surf the virtual world now does not have to anxious
and agitated with Internet speeds that still have been present lemod because
now 4G technology, with a very fast pace you can download large files in just a
few minutes even seconds, so check out some discussion about 4G technology:
1. History 4G
Cellular system has four main phases or generations. The first generation or 1G only supports voice calls only. The second generation, 2G, introduced digital transimis first data and offer support, even though the focus is on voice calls. Second-generation mobile-phone based on one or two standards: GSM and CDMA. In other cases, an average of around 9.6 Kbps data speeds, such as modems 90s. 2.5G is an advanced level where everything is a little blurry. In GSM, the standard called GPRS, which offers capabilities for better data transmission, which became known as 2.5G. GPRS also developed the EDGE network (data rates up to 400 Kbps) which is still used by many mobile phones today. While in CDMA, 2.5G referred to as 1XRTT, or just 1X. In the real world, it is known as EVDO and promises download speeds of 600 Kbps to 1.4 Mbps. There is some debate on what 3G lifted later. 3G is defined instead of the underlying technology, but of speed: up to 2 Mbps. At the advanced level, known as HSDPA + or Turbo 3G, can support download speeds of up to 14 Mbps. And then of course 4G.
2. Definition of 4G
4G is a loose term for the fourth generation mobile communication, offering speeds roughly 10 times faster than 3G is the third generation. Higher data speeds can make more smartphones can be paired with a PC, with mutimedia and better gaming capabilities.
3. Technologies of 4G
4G technology consist of two: LTE and Wimax. They are not aligned with CDMA vs GSM competition. There is little debates whether LTE and WiMax meet all the requirements for 4G technology. International Telecommunication Union suggests that WiMax is actually part of the 3G family.
WiMax has its roots in the wireless broadband industry and supported by IEEE, while the LTE standard is a joint venture made some phone companies. WiMax requires a new network to be built as LTE is an evolution of the CDMA/HSPA.
4. 4G Speed
In theory maximumnya speed of 2 Mbps. But in practice, you will not get more than 500 Kbps to 1.5 Mbps, depending on the location, provider, and so on. WiMax can provide download speeds up to 6 Mbps and 1 Mbps upload. LTE say they could be better. They can provide speeds of 100 Mbps and supports uploading an average of 50 Mbps. But remember, this is a rough theoretical speed. PC World reported that the HTC EVO 4G mobile phone is never dropped from 3 Mbps speed in the test.
5. About two 4G standards
LTE or Long Term Evolution is a standard created by a group called the 3rd Generation Partnership Project. LTE is an IP network that is based on the same central porotokol on the Internet, TCP/IP.
Both LTE and WiMax use the principle of Orthogonal Frequency-Division Multiple Access, the concept has been around since the 1960s. OFDMA is based on the idea of frequency-division multi-coating, which is a method for transmitting multiple data streams through a channel. In the case of OFDMA, a digital data stream transmitted need broken down into different carrier. Bearers of these reserves to meet in the end.
The difference between LTE and WiMax lies in how they handle the channel to process the data. WiMax to process all the information in a wide channel. That is, two-thirds of the canal is used for dowload, while the third is used for uploading. LTE divides the channel into two parts using the multi-frequency-division coating, so the download speed and upload it more balanced.
