What is LTE?
In mid -2009, most of the third -generation mobile technology networks (3G) were operated. These networks include a global mobile communication system (GSM) and code divisions (CDMA). Newer technologies, long -term evolution (LTE), can improve these older networks and eventually replace. LTE access promises faster speeds for mobile wireless users and lower costs and increased capacity for network providers.
CDMA prevails in the United States; As of 22 September 2008, however, more than 80% of world mobile phones run on GSM networks. But CDMA and GSM are still growing. Verizon Wireless® and Sprint® use CDMA, while AT&T®, Apple® iPhone ™ distributor in the United States, uses the GSM standard.
LTE is evolving that wireless wireless company providers use both types of networks to transition from 3G technology to nets and 4G equipment). For consumers, LTE will enable the existing app to run and make new APL availableIce for mobile phones. Improved video and mobile phones can be included. As a result, service providers should be able to get more data transfer from their existing cells and possibly reduce the cost of starting their networks. Because LTE connects to existing networks, providers can plan a trouble -free crossing, then continue to use the Legacy CDMA and GSM networks as backups.
The way LTE reaches its speed could lead to a disadvantage: the initial costs of service providers and consumer for upgrading equipment. LTE accepted technology with multiple inputs (out) with multiple inputs (out). As a result, cell backup may require further transmission and receiving antennas. Mobile phones can have one transmission antenna and up to two recover antennas. Services may need to upgrade backup and consumers will have to buy new phones to use these UPsGraded nets.
The industrial group that provides LTE network standards is a part of the 3rd generation (3GPP). LTE was first developed for data transfer. At the beginning of 2009, the executives and manufacturer of equipment for equipment and equipment manufacturers joined to create a vote via LTE via the Generic Access Forum (Volga). Volga is devoted to expanding LTE access technology, so it can also support text messages about voice and short messages (SMS) using existing networks. The aim of this forum is to allow wireless broadband providers to switch to this new technology without converting their entire networks from the ground up.
