                   can further enhance network performance because interference is mitigated between inter-eNodeBs.

Future system requirements for IMT / LTE & IMT2020 networks                  25

According to the 3GPP, in LTE-Advanced, the focus is on higher capacity. The motivation for further
                   developing LTE towards LTE-Advanced is to provide higher bit-rates in a cost-efficient manner
                   and, fulfil the requirements set by the ITU for IMT Advanced as shown below:

?  Increased peak data rate, downlink 3 Gbps, uplink 1.5 Gbps;
                   ?  Higher spectral efficiency, from a maximum of 16 bps/Hz in Release 8 (R8) to 30 bps/Hz in
                      Release 10 (R10);

?  Increased number of simultaneously-active subscribers;
                   ?  Improved performance at cell edges, e.g. for downlink 2×2 MIMO > 2.40 bps/Hz/cell; and

?  Enabled Carrier Aggregation (CA), enhanced use of multi-antenna techniques and support for
                      Relay Nodes (RN).

As LTE-Advanced continues to evolve, new CA configurations are added, and new features are
                   introduced in upcoming releases of the 3GPP specifications, such as Coordinated Multi Point
                   (CoMP) introduced in Release  11 (R11). The main reason for introducing CoMP is to improve
                   network performance at cell edges.

IMT2020 standards are yet to be finalised in 2020. Most IMT-2020 systems are in development stage
                   leading towards pre-commercial phase. It is expected that IMT2020 peak data rate measured in Giga
                   bits per second (Gbit/s) will be 20 times that of IMT-Advance in accordance with Recommendation
                   M.2083.

However,  they  will  be  significantly  ahead  of  what’s  currently  available  with  4G.  A  minimum
                   expectation for commercial IMT2020 services is for them to be tens of times faster than 4G, which
                   would make even current broadband speeds look sluggish in comparison. The exact speeds are yet
                   to be finalised, early tests are already achieving remarkable results and these give us a good idea of
                   what we can expect when IMT2020 finally launches:

(a) DOWNLOAD SPEEDS

The Next Generation Mobile Networks alliance states that for something to be considered IMT2020
                   it must offer data rates  of several tens of megabits per second to  tens of  thousands of users
