3GPP Release-12 RAN Enhancements

The ones which fascinates a lot are :-

Improved local area mobility using Dense Radio Network
ProSe/D2D - Device to Device Proximity services

Dense Radio Network

D2D Service

5G Technology Candidate :- Access Optimization

Traditional concept of having a Uplink / Downlink channels irrespective of TDD/FDD mode is the major  point that defines how the spectrum is well utilised and also the ability for further aggregation.

3GPP RAT development team is working on existing Radio Network Coding to enhance the way of using the Channel without decoupling Logically (TDD) or band wise (FDD).

With this improvement, the Career Aggregation will be simpler than before and bandwidth can be provided on demand depending upon the availability with simple access procedure across different bands/RATs.

5G Technology Objectives

BIG DATA analysis has proven that it can add value to existing business and provide innovative solutions. This leads to revolutionize the business ideas across globe.

It requires a natural partner in terms of broadband connectivity on the fly to help business community in thriving the world economy. ICT Community's main aim to serve this requirement and  empower the growing demands of rural communities. This relationship outlines required objectives for 5G Technologies as stated below.

• 5G Networks will be able to serve 100 billion connections.
• 10 Gb/s will be the data rate per user,
• 5G Netwoks will have new RAT + LTE+LTE-A+WiFi+GSM+HSPA.
• 5G Netowkrs may serve 3 folds of world population in M2M connections.

FarEastTone to have APT700 for LTE by Ericsson

In my previous posts , I have highlighted the APT700's momentum, now...

FarEasTone of Taiwan is teaming up with Ericsson to launch LTE with APT700.
APT700 becoming highly in demand at various APAC & LATAM markets.

It helps the operator to have the capacity to serve more customers and provide extensive indoor coverage quality , all these at the very same network gear cost of any 2300/2100/1800 band LTE network.

SRVCC - Single Radio Voice Call Continuity : Is it possible in India ?

Most of the existing operators having heavily invested CS Core network elements across the entire country. Launching IMS Core as a replacement for these network elements is not a easy jobs from the economical and practically not that easy.

Geography & Customer base are huge with highly complex interconnects across the nation.

SRVCC requires top quality GERAN/UTRAN .

Which is still a question mark....due to many factors including the above pointed Geo + Population.

Even-though Reliance JIO starting with LTE + IMS Core , it may not have a strong target GERAN/UTRAN network. I don't think that there is a partner to do so, instead they may opt for CSFB which helps RJIO and its partner in more better way in terms of implementation.

The 1800 MHz they have acquired is not for GERAN/UTRAN instead they may use it for LTE-FDD Network.

So conclusively, SRVCC may not come to India...

SRVCC Background :-

With IMS as core (already deployed), SRVCC become the ultimate choice for Japanese and US mobile operators to provide multimedia services. It was easy for them to go for SRVCC instead of troublesome CSFB ( only in congested areas) with complicated requirements in terms of tecchnical capabilities at UE & Network.

SK Telecom - South Korea : LTE Network Evolution Strategy Diagram

SK Telecom is the leading operator in South Korea with close to 16 Million Subscriber. Which is 56% of their total customer base.

SK has 47% share in the total south Korean LTE Subscriber base i.e. 33.83 Million.
