What is 4G LTE

Introduction to 4G LTE

Experts around the world are working hard to meet ever increasing need to have even faster mobile internet connection. Mobile broadband services are rising in the US market. Currently, Wimax network technology, based on IEEE standards, is leading the market with Sprint and Intel as its prime supporters.  However, Wimax will soon face a rival that can probably shake its base. The 4G Long Term Evolution (LTE) feature is coming our way in near future. Its arrival is most expected in March 2011 to fulfill the standards set forth by International Telecommunication Union (ITU). The LTE version of high speed 4G wireless internet connection is expected to compliment your mobile devices. It can give a backseat to your domestic internet connection as it will provide overall solution for laptops, phones and other mobile devices. It is designed to facilitate easy internet access, games as well as IPOV transmission.

Overview of 4G LTE Technology

Both, 4G LTE and Wimax, use OFDM wireless technology which is also known as Orthogonal Frequency Division Multiplexing. This technology helps in transmitting the data in several parallel data channels. Both are more relevant to transfer data.  LTE technology is designed to speed up the download to 100 mbps at higher mobility and 1Gbps at lower mobility with the uploading speed of 50 mbps which is much higher than the currently available downloading speed of 6mbps and uploading speed of 1 mbps. This means you can easily download two MP3 files, of 5 minutes duration each, in a second which will otherwise take 14 minutes to download, using the current mobile internet connection. Wimax equipments will also have cheaper rates.

According to ITU standards, 4G LTE is expected to allow roaming connections with home network, making it more reliable. It will also have the flexibility to support huge array of local service providers with various applications, making it a cost effective solution to the end user. It will also support user friendly applications, along with the equipment adapted for overall use. It is also clear that Verizon wireless and AT&T mobility are planning to upgrade their network to 4G LTE.  Carrying all these advanced features 4G LTE will surely take some more time to come in market. Whereas, Wimax is already present in the market,  to serve the current needs.  Eventually, both 4G and Wimax will enhance its potentiality and will offer high end competition to the current broadband services.

Wikipedia defines the technology as “4G stands for the fourth generation of cellular wireless standards. It is a successor to 3G and 2G families of standards. Speed requirements for 4G service set the peak download speed at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users).

A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to smartphones, laptop computer wireless modems and other mobile devices.Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.”
