Know More In Networking 4.5G Technologies

At the end of last year (December 8, 2016), Huawei collaborate with Telkomsel operator trials 4.5G technology held in the city as part of the 'roadmap' technology 'broadband' in nine cities across Indonesia. Previously, Huawei and Telkomsel to test mobile technology 1 Gbps in Jakarta, which is the first step of the implementation of 5G technology in Indonesia.


Actually, not only have implemented 4.5G Telkomsel, Indosat Ooredoo also claims to have prepared the modernization of the network since 2012 and implements 4.5G 2016. Although users may not feel.

1G1G network was first discovered in 1980 when the AMPS in the United States is working with TACS and NMT in Europe to make a breakthrough in network technology. The new standard of network technology has resulted in the mobile phone with 1G technology worked out and produce mobile phones the size of a fist. 1G technology can only send voice and text messaging.

DRAWBACKS OF 1G
  • Poor Voice Quality
  • Poor Battery Life
  • Large Phone Size
  • No Security
  • Limited Capacity
  • Poor Handoff Reliability
2G
At the beginning of 1990 appeared digital mobile network technology, which almost certainly has many advantages. 2G superior in sound quality clearer, more awake security and greater capacity. GSM appear first in Europe, while in the United States rely on D-AMPS and CDMA. CDMA and GSM are considered to represent 2G wireless network technology.

2.5G
GPRS (General Packet Radio Service) or 2.5G is a breakthrough innovation from 2G network technology. GPRS became the forerunner of the current emergence of 4G. Created in 1997, then replace CSD GPRS. Just for comparison, GPRS charge per kilobyte of data while the CSD charge of data per minute.

3G
3G technology is divided into GSM and CDMA. The 3G technology is often called a 'mobile broadband' for its excellence as a modem for the Internet that can be taken anywhere. 3G is a standard set by the International Telecommunication Union (ITU) adopted on IMT-2000 to be applied to the mobile phone network. Through 3G, mobile users can have instant access to the Internet with a bandwidth of up to 384 kbps.

Rapid access is a mainstay of 3G is certainly capable of providing diverse facilities to the users like to watch videos directly from the Internet or talk with others using video.

FEATURES OF 3G TECHNOLOGY
  • Providing Faster Communication
  • Send/Receive Large Email Messages
  • High Speed Web / More Security Video Conferencing / 3D Gaming
  • TV Streaming / Mobile TV / Phone Calls
  • Large Capacities and Broadband Capabilities
3.5G
HSDPA (High Speed Downlink Packet Access) the remainder of 3G technology. HSDPA is often called 3.5G generation because the technology is still running with the 3G platform. In theory the speed HSDPA data access as 480kbps, but certainly much faster HSDPA data. After several years of CDMA 2000 technology upgrade evdo their network, EVDO rev A 3.5G equivalent to 10 times faster than EVDO rev 0 as well.


4G
4G network is the fourth generation of wireless networks as a comprehensive communications network solutions and secure with data speeds much faster than the previous generation. Actually there are two standards for 4G WiMax and LTE (Long Term Evolution) 4G LTE but is better known now.

4G networks are able to provide high quality services and high data transfer rates with better reception quality, more stable flow of data transfer, as well as the exchange of information more quickly. 4G provides a minimum data transfer rate of 100 mbps (megabits per second) when the user is moving at high speeds and 1 Gbps (gigabit per second) in a stationary position.
What Was 4.5G
4.5G technology is actually not a new leap. 4.5G technology only provides additional capacity for 4G network and offers a number of advantages for customers. 4.5G technology offers lower latency so that revenues faster access to services. Customers can also enjoy increased speed of the internet than ever before. Upload and download Internet speeds can be increased by up to 20 percent.

Through the implementation of 4.5G of this technology, users can enjoy faster internet access, High Definition quality video 9HD), and a better gaming experience via a smartphone device. Additionally, 4.5G technology provide new services, such as IOT narrowband (NB-IoT) and LTE-integrated Trunked Radio System (LiTRA).
Since record speed 4G LTE (Long Term Evolution) breaks 1.22 Gbps by operator Deutsche Telekom along with vendor Huawei, the derivative label LTE, the LTE Advanced Pro (LTE-A Pro) started much discussed, especially after some of the world's operators did commercialization after No version of the LTE-A, LTE-U, and LTE-M. What is LTE-A Pro?

By definition The 3rd Generation Partnership Project (3GPP), LTE Advanced Pro is a radio capabilities are further enhanced. LTE Advanced Pro make mobile broadband services more efficient network operators, provide higher quality and enable a variety of new services to the LTE network. In essence, LTE Advanced Pro makes communication lines and faster 4G data.

In addition to Huawei, Nokia also offers LTE-Advanced Pro with 3D Beamforming. The advantage of this technology is capable of generating capacity 4X higher uplink and downlink 3X greater in TDD spectrum. LTE Advanced Pro with 3D Beamforming enables carrier aggregation even at the cell edge by using the Inter-Site Carrier Aggregation of LTE TDD and FDD. Even with the Nokia Intelligent Beamforming able to increase throughput at the cell edge folding 2X TDLTE, also software for uplink 3X acceleration in FDD-LTE.

Nokia claims the LTE FDD-LTE and TD-LTE Nokia has the best performance today. Inter-Carrier Aggregation Site unique Nokia combines carrier TDD and FDD different from the base station located in many different sites. This solution will result in higher throughput at the cell edge by using the Release 10 that already exist.

Intelligent Beamforming Nokia now includes the capability of 84 (8 transmit antennas and four receiver antennas) for TD-LTE which will increase the rate of cell edge doubled and throughput sector generates on average 50% higher.
