What Is Long Term Evolution (LTE)

LTE stands for LongTerm Evolution. It is the standard wireless communication platform for high-speed data in mobile phones and other data devices like tablets and USB modems.

LTE is a 4G technology that's fully capable of handling high-speed mobile data for capable devices.

The target of LTE is to increase the capacity and speed of wireless data networks and provide significantly faster data rates for both uploading and downloading. LTE is based on standards developed by the 3rd Generation Partnership Project (3GPP). Much of the LTE standard addresses the upgrading of 3G to what will eventually be 4G mobile communications technology.

Here's the line-up of LTE capable smartphones, now available in the Philippines. Some of these devices are not yet officially released and are only available from the grey market.

The iPhone 5 is the thinnest and lightest iPhone and with LTE capability you can browse, download and stream content at remarkable speeds. Compared with the previous iPhones, it has a larger display, a faster chip, faster wireless technology and a better 8MP iSight camera. Although the iPhone 5 is an LTE device, its LTE feature was just activated recently with the iOS 6.1 update.

The country's first water and dust resistant LTE smartphone Sony Xperia V, supports download of up to 100Mbps perfect for downloading videos and online gaming. Watch TV shows, movies and your own video clips on the 4.3'' HD Reality Display powered by the Mobile BRAVIA Engine 2.

The Asus PadFone 2 both mobile phone and tablet that operates with Android 4.0 (Ice Cream Sandwich). Eliminate the hassle of synchronization when the two devices are connected as all storage is inside the phone.

The Samsung Galaxy Note II LTE a smartphone loaded with Android 4.1 Jelly Bean comes with other features like multi-window format where user can view multiple displays simultaneously. The design includes a bigger screen while maintaining a slim body to fit just right in your hand.

Successor of the Lumia 900, the Nokia Lumia 920. This high-end smartphone retains the beauty and style of its predecessor and offers added features such as the PureView technology that greatly boosts camera performance, and comes with a 2000mAh, giving it an excellent battery life for the entire day.

The HTC One SV features the ImageSense technology, which redefines images to a different level. Like many other HTC handsets, this one comes with Beats Audio, making listening to music a pleasant experience. The latest feature it has is the HTC Connect, which makes it compatible to home entertainment systems. Plus, it has LTE connectivity.

The Samsung Galaxy S III LTE has that entire predecessor Samsung Galaxy S III offered, with a 4.8'' super AMOLED capacitive touch screen but amped with a 2GB RAM and Android Jellybean OS.

The HTC One XL features 1.5GH Dual Core, 1GB RAM, 32 GB, 4.7'' Screen, Android Ice Cream Sandwich (ICS) with 8 megapixel camera, Beats Audio, 4.7-inch Gorilla glass touch screen, WiFi, and BlueTooth.

The ZTE T81 has 1.5GH Dual Core, 4.0'' Touch Screen, Android ICS with 5 megapixel camera, WiFi, and BlueTooth.

Finally, the Huawei Ascend P1 LTE also has a 1.5GH Dual Core, 1GB RAM, 4.3'' Super AMOLED Capacitive Multi-Touch Screen, Android ICS with 8 megapixel camera, WiFi, and BlueTooth.

Evolution of Mobile Standards

What is 1G?

First generation refers to the analog ''brick phones'' and ''bag phones'' as they were first introduced for mobile cellular technology. Cell phones began with 1G and signify first generation wireless analog technology standards that originated in the 1980s. 1G was replaced by 2G wireless digital standards.

What is 2G?

2G signifies second generation wireless digital technology. Fully digital 2G networks have replaced analog 1G, which originated in the 1980s. 2G networks first commercially began on the Global System for Mobil Communications, or GSM, standard. 2G on GSM standards was first used in commercial practice in 1991 by Radiolinja, a Finnish GSM operator that was founded on September 19, 1988. Radiolinja is now part of Elisa, which was known in the 1990s as the Helsinki Telephone Company.

In addition to the GSM protocol, 2G also utilizes various other digital protocols, including CDMA, TDMA, iDEN and PDC. GSM is based on TDMA.

What is 2.5G?

2.5G wireless technology is a stepping stone that bridged 2G to 3G wireless technology and is sometimes used to describe those evolved technologies that were first considered as being 2G. While 2G and 3G have been officially defined as wireless standards by the International Telecommunication Union (ITU ), 2.5G has not been defined and was created only for the purposes of marketing.

As an interim step up from 2G, 2.5G has seen some of the advances inherent in 3G networks (including packet-switched systems). The evolution from 2G to 3G has ushered in faster and higher-capacity data transmission. Several technologies that have been considered as the evolutionary step to 3G include EDGE (part of the GSM family) and CDMA 2000 1X; at times these technologies are called 3G as they both meet some of the ITU requirements for 3G standards.

What is 3G?

3G is the third generation of mobile phone standards and technology. 3G supersedes 2G technology and precedes 4G technology. Current 3G systems have been established through ITU's project on International Mobile Telecommunications 2000 (IMT-2000).

3G technologies have enabled faster data transmission speeds, greater network capacity and more advanced network services. In May 2001, NTT DoCoMo (Japan) launched the first pre-commercial 3G network - branded as FOMA. Following the first pre-commercial launch, NTT DoCoMo again made history on October 1, 2001, with the first commercial launch of 3G in Japan.

UMTS-HSPA is the world's leading 3G technology. By 2015, UMTS-HSPA and LTE 3G technologies are expected to account for 3.9 billion global subscriptions, compared to 569 million CDMA EV-DO subscriptions and 59 million WiMAX subscriptions.

What is 3.5G?

Similar to the 2.5G acronym, the reference to 3.5G is not an officially recognized standard by the ITU. It is an interim or evolutionary step to the next generation of cellular technology that will be known as IMT-Advanced according to definitions by the ITU. IMT-Advanced will comprise the fourth generation of cell phone technology. The acronym 3.5G is also known as ''beyond 3G.'' 4G Americas does not use the terms 3.5G (or 2.5G) in respect of the official definitions provided by the ITU. The technologies within the GSM family that are considered as beyond 3G include HSPA+ and LTE. These 3.5G technologies are often called pre-4G as well.

What is 4G?

4G is the term used to refer to the fourth generation of mobile wireless services that has been defined by the ITU and its Radiocommunication Sector (ITU-R) and established as an agreed upon and globally accepted definition in IMT-Advanced.
