LTE or Long Term
evolution refers to a wireless communication standard featuring high-speed data
for tiny mobile phones. As a viable communication standard, LTE entails
numerous excellent features among which there are some features, which may
often be overlooked though these are not at all minor in respect of functional
significance.
At present, ITU-R’s IMT
system uses various frequency bands, and LTE provides essential supports for
all these frequency bands.LTE has enhanced flexibility for spectrum.Wide cells
such as 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz are at a high standard.
The sizes of these cells range from tens of meters radius to 100 km radius macro
cells and support for these have been made available by LTE.
In the village areas,
lower frequency bands are used where the optimal cell size is 5 km and 30 km is
regarded as reasonable performance whereas approximately 100 km cell sizes are
supported with approved performance. With a view to supporting mobile broadband
at a high speed, higher frequency bands are used in city areas. LTE can provide
supports more than 200 active data clients per 5 MHz cell.The architecture of
LTE is simplified.Only eNodeBshas constituted E-UTRAN’s network side.
For building a
relationship of inter-operation and co-existence with renowned legacy standards
such as GSM, UMTS and CDMA2000, support is needed to a great extent which LTE
also includes. As a user, you can make a call or simply transfer data to and
within an area via an LTE standard. It has also a radio interface which is
packet switched.
If support is required
for Multicast-Broadcast Single Frequency Network, LTE will do the best. It is a
feature that can deliver Mobile TV services as it uses the infrastructure of
LTE. However, it competeswith DVB-H-based TV broadcast.
