5G – Whole world will become a Wi-Fi zone

Shares

In these days we are in search of Wi-Fi zone everywhere. Few countries have turned themselves into fully Wi-Fi zones. But in developing and underdeveloped countries, this features is not too easy to avail. But this scenario will change with the introduction of 5G technology and services. Using the 5G network we can convert the […]

WHAT ADDITIONAL FREQUENCY BANDS ARE BEING CONSIDERED FOR LTE?

Shares

Word Radiocommunication Conference 2007 (WRC-07) identified additional frequency bands for IMT, but most of the allocations are not really global: • 450-470 MHz – was identified to IMT in all three Regions. The band is already allocated to mobile service on primary basis globally, but it is a very small band. • 790-862 MHz – was allocated to […]

What is the purpose of having Multi-Antenna processing in LTE?

Shares

LTE is supposed to have high data rate and throughput compared to previous technologies. For this reason and purpose LTE supports several different multi-antenna techniques and processing in order to enable high spectral efficiencies in a wide range of scenarios. Mainly there are three multi-antenna processing schemes which run in LTE. There are different flavors […]

What are the Uplink multi-antenna schemes in LTE?

Shares

Only the downlink in LTE supports multi-antenna processing in the form of spatial multiplexing for a single UE. So far, two multi-antenna related techniques are explicitly supported in the LTE standard for uplink: UE transmit antenna switching In antenna switching, the UE may transmit over either of two transmit antennas. This corresponds to a poor […]
