what is 4G or LTE
LTE stands for “Long Term Evolution” – it is a technology to deliver speeds-up to 100Mbps (technically) in an ideal environment. 4G is a Standard in Mobile Network Technology and stands for “Fourth Generation”-the latest after 2G and 3G.
what is the difference between GPRS, EDGE, 3G and 4G?
a) GPRS: refers to a service on the 2G network that provides basic data up to 56kbps (similar to dial-up speeds)
b) EDGE: It is a 2.5G technology. An enhancement of the 2G technology which provides higher data transfer rates compared to GPRS (the default on 2G).The speeds can go up to 144 Kbps
c) 3G: 3G technology provides faster / higher data transfer rates compared to the 2G network (EDGE & GPRS).This technology can offer speeds up to 21 Mbps
d) 4G: This technology rides on LTE platform and is the latest in the world of mobile data transfer. It is the next generation of mobile communications. Currently it is the most advanced technology available. Theoretical data downlink speeds can go up to 100 Mbps.
How is 4G better than 3G?
Being the latest platform of mobile communications 4G - LTE can enable real mobile (wireless) broadband experience. The technology supports theoretical download speeds up to 100 Mbps and upload speeds up to 50 Mbps. It has a very low latency rate (< 5-30 ms) making it suitable for all type of high speed applications and services.
4G LTE can be used at home or your office for :
a) Wireless internet access
b) Access rich content and multimedia applications eg: e-learning, HD content-movies etc…
c) multiple downloads of heavy files, high definition multimedia content at the same time will be possible
d) Higher uplink and downlink speeds
e) Seamless online streaming – without buffering
f) High definition online gaming
g) Access business applications that require higher speeds and last mile connectivity
4G or LTE is going to bring fastest wireless broadband Internet access in India. However, being a wireless technology-bandwidth is a shared resource, hence number of simultaneous defines the final delivered speeds.
difference between a and multi mode
1. A Single mode device will support 4G LTE data network only.
2. A Multimode Mode device will support 2G / 3G / 4G network
Please note that, in India, presently voice and SMS is not supported on 4G. In 3G & 2G your SMS and USSD along with Data Services will work.
Re: what is 4G or LTE
Wrong info/ insufficent info
LTE is Long Term Evolution - it is the technology on which 4G works
Just like HSDPa,HSPA on which 3G works
Actually Gprs is 2.5G and Edge is 2.75G
But we simply say them as 2G and 2.5G
Edge can speed upto 237 kbps
And 3G speeds upto 384kbps and it is 3.5G which speeds upto 21mbps
