Deep Dive Into LTE

4G LTE is gradually but progressively making its presence felt in India. Though 4G LTE is still in its promising stages, but is shaping up to be a significant requirement in future. Let us take a look at what 4G LTE is and what is the current scenario in India.

What is 4G, LTE and the difference between 4G and LTE?

4G where G stands for ‘Generation’ was developed by 3rd generation partnership project (3GPP) aiming at providing up to 10 X speeds of 3G networks. 4G LTE (Long Term Evolution) is one of the several competing 4G standards (some other being with Ultra Mobile Broadband (UMB) and WiMax).

4G LTE band 40, 2300 MHz (TDD-LTE) is the LTE bandwidth that is available in India as of now. Indian government has also auctioned 1800 MHz (FDD-LTE) spectrum, but no operator is offering that till date.

3G VS 4G LTE

The difference is in Speed. While 3G networks are supposed to offer anything between 3 Mbps to about 21 Mbps, but in practical use, the download speeds are much lower. In India, TRAI wants to set minimum 1 Mbps download speed for 3G which in itself speaks about its dismal scenario.

What is the difference between TD LTE and FD LTE? Which one is better?

Radio communications occur in both directions. This is referred as Duplex Scheme and this two way communication can take place in two possible ways – Time division Duplex (TDD) and Frequency Division Duplex (FDD), thus giving two type of LTE standards.

Mobile operator Idea Cellular is currently deploying its LTE network in a number of regions including Kerala, Maharashtra & Goa, Andhra Pradesh, Karnataka, Madhya Pradesh & Chhattisgarh, Punjab, Haryana, North East, Tamil Nadu, and Orissa. Idea currently has LTE spectrum in 11 of the country’s 22 service areas.

Mobile Upgrades: Killing The Product Before Its Time?

Have to agree. The speed of newer phone models within the same series and newer app versions lead to more thought put into buying decisions. Phone lines have a definite short shelf life

Frequently upgrading the software is a real problem as updating the software might cause your phone to lag because of the older hardware.

They should come out with upgrades for the specific phones and not for the separate Operating System. This way a special version for your phones specific hardware can be made
