How to appear 4G technology will affect the adoption of VoIP Mobile

When VoIP crossed the road to the mainstream, new developments in internet technology continued to have an impact on broadband telephone growth. One new technology is expected to maintain, if it does not help, VoIP to get broader acceptance is the fourth generation (4G) in cellular wireless technology, which successful 3G system is currently being used. Competitive 4G technology is expected to provide safe broadband connectivity with perfect gig-bit speed to demand applications that require high bandwidth and high speed, such as online games, multimedia streaming, and IP-Telephony.

Some cellular operators have launched the infrastructure and equipment needed to spread new technology, such as the 4G system applied by TeliaSonera in Stockholm and Oslo in Scandinavia. In addition, the release of the first 4G mobile market – HTC EVO 4G – this year signifies the beginning of the new era in cellular connectivity.

Compete 4G Technologies.

The most striking aspects that define 4G technology are high throughput requirements (up to 1 gbit / s); Calls from CDMA radio technology used in 3G systems support multi-carrier transmission using frequency domain equalization schemes; And the use of several smart antennas for transceivers. Although there are quite a number of implementations proposed for 4G, two candidates so far managed to attract most investors and adherents: WiMAX and LTE.

WiMAX stands for world interoperability for microwave access, telecommunication protocols that provide wireless broadband access ‘last miles’. The WiMAX version (802.16E) currently offers up to 40 Mbit / s, it is still far below 4G standards, but the Revised IEEE 802.16M will soon be expected to increase speeds of up to 1 Gbit / s for fixed connections.

LTE stands for long-term evolution, increasing standards in the universal cellular telecommunications system (UMTS) which is part of the revised 3G system in 2008. The first LTE release also fails from 4G standards on throughput – and for this reason the release is called 3.9G. The two biggest cellular operators in the US – Verizon Wireless and AT & T Mobility – have announced that they will convert their existing system into LTE early 2011.

VoIP and 4G.

One or both competing 4G protocols are expected to provide all-IP networks with high bandwidth and low latency. 4G standards are expected to integrate voice services above the data stream, to provide voice calls through cellular connections or unmatched VoIP and quality.

WiMAX is a wireless Ethernet form like WiFi, but the first offers more in terms of range (WiMAX signals can include several kilometers), sustainable throughput and service quality. However, WiMAX runs on a licensed radio spectrum unlike WiFi which is on a ribbon that is not licensed and not set. LTE, on the other hand, is more similar to a cellular system but offers cellular broadband capabilities that are useful for package transmission.
