A variety of new powerful tool to quickly invade the country market. Ranging from advanced mobile phones, tablets, netbooks, notebooks, and even Internet-based computing systems or cloud computing which all require a means of rapid communication.
Terminology broadband or broadband communication is already familiar. However, it seems the feeling users can not understand the changes that occur because there are just no words slow.
This may be because the growth increment item size can not afford followed networking capabilities. Excessive expectations of greatness 3G network is just disappointing despite four years of operation there is simply no one bervideo call, or watch digital TV on the mobile screen.
Preliminary estimates were missed, even though 3G technology has reached as high-speed packet access (HSPA) or 3.5G and soon entered the 4G.
The presence of the gadget is always faster than by holding a communications network technology. Old story always repeats itself, the presence of 3G networks in this country only in 2006, but previously had 3G phones present.
Much like now flooding gadgets, especially gadgets based Android operating system (either the smartphone or tablet). Previously had slid from the Apple iPhone device (smartphone) and IPAD (tablets). However, without good internet network will only function as a mobile phone.
Lack of support led to the delay and once again the network vendors trying to provide solutions to operators. This time the vendor giant Ericsson offers new hope with the latest long term evolution (LTE), a cellular technology pragenerasi fourth (pre-4G). LTE demo before, they've done Alcatel-Lucent in Jakarta.
New Paradigm
The change habits quickly rolling, than just a personal relationship to form a community, citizen journalism thrives social networking tools. All want to share is like a herald, not only writing, but also through the photographs.
No wonder the communication network load will be heavier. Ericsson estimates that there will be 50 billion devices connected to each other telecommunication equipment in 2020. By simply relying on existing technology clearly will not be able to handle.
"Moreover, Indonesia is one country where growth of Internet connections fully supported by the growth of mobile connections," said Mats Otterstedt, President of Ericsson Indonesia. This was revealed in the show demo LTE technology in Jakarta last week, in which Ericsson introduced two LTE technology, whether based on frequency division duplex (FDD) or time division duplex (TDD).
In a demonstration in Jakarta last week, the LTE can reach speeds of 100 Mbps for downlink and uplink of about 20 Mbps. When applied to high-quality streaming video access definiton (HD) recorded speed of 25 Mbps downlink.
A hope of re-emerged, with LTE, for example, facilitated the implementation of live television. In addition to forwarding signals from the field, LTE also has a latency (lag because of the hardware) is very small. During this communication show host in the studio with a reporter in the field is cut off very long, high latency is due to the communication must be via satellite.
However, LTE migration is dependent on regulatory policy in allocating frequencies. For the conditions in Indonesia other than through efforts on the frequency of existing refarming, also possible at frequencies adjacent to the spectrum in the WiMAX technology, the 2.3 GHz band (2360-2390 MHz range). In addition, there will still be on the 700 MHz band which is still occupied by analog television broadcasts. If you have already switched to digital TV next seven years, the use of 700 MHz band would be more efficient and the rest could be used for LTE.
Meanwhile, growth in the world accounted for LTE networks will be dominated by Asia-Pacific region, in the next five years in this area there will be about 43 percent of global LTE connection, in which China is so far behind in the 3G LTE will dominate half of the Asia-Pacific connection , others such as Indonesia, Japan, and South Korea.
Migration to LTE network operators beginning in Western Europe and North America since last year, which this year reached 70 percent. This LTE network of whom have been held carriers such as TeliaSonera (Europe) and Verizon Wireless (United States).
Party Ericsson LTE handle commercial contracts with AT & T, MetroPCS, and Verizon in the United States, in addition to TeliaSonera in Norway and Sweden, as well as DoCoMo in Japan.
