How and Which KPI to Check before and after LTE Launch Operator always needs to check LTE performance before commercial launch and after commercial launch and here I write how and which KPI to check.As This is general guide so it is change for different operator but it cover all KPI. There are two types … Read more

LTE KPI Measurement Methodology and Acceptance Procedure Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s for only at network start up stage and now a day worldwide so many operator starts to launch LTE and so this is the way for them to check of KPI … Read more

S1 and X2 Bandwidth Dimensioning Procedure The figure below denotes the location of the X2 and S1 link with respect to the other network components within the LTE network. In general, the traffic on S1 interface is divided into two different plane, the control plane, which uses SCTP (Stream Control Transmission Protocol) developed by IETF … Read more

How Time Slot Allocation for Uplink and Downlink LTE Here I write down on How Time Slot Allocation for Uplink and Downlink LTE and How Cyclical Prefix Allocation for LTE Time Slot Allocation for Uplink and Downlink – TDD specific The time division nature of LTE TDD will also require radio engineers to consider how … Read more

UE Capability and Cell site relation to traffic in LTE It is important to remember that the composition and penetration of various UE types will also have an impact on the final achievable cell throughput level. A high concentration of relatively low end UEs will result in low resources utilization efficiency, thereby bringing down the … Read more

Some Special Antenna Technologies and Scheduling Mode for LTE MIMO and Beam Forming are critical features in determining the actual link budget required for the Operator’s network. However, these two features are also critical features from a capacity perspective as they can also improve the efficiency of frequency reuse and reduce the intra-frequency interference within … Read more

3GPP Services Classification and EUTRAN Capacity Limiting Factors Here I write on 3GPP Services Classification and EUTRAN Capacity Limiting Factors for LTE. 3GPP Services Classification Being a data centric technology, LTE has well defined classifications for Quality of Service. In general, there are two main classes of service type, with Guaranteed Bit rate vs with … Read more

Definition of EUTRAN Capacity Limiting Factors for LTE Here I write not all but important List of EUTRAN Capacity Limiting Factors for LTE and its definition. Impact of Interference on Capacity Interference is always a main contributor to capacity degradation in 1G to 3G cellular network and LTE is no difference. Besides external interference, there … Read more

Operating Frequency Band and RSRP for LTE Choosing which frequency band to operate a LTE network is one of the most critical decision. Operator has to make when it comes to capacity planning. The frequency propagation and penetration characteristics will determine the number of sites that need to be built in order to cover the … Read more

Capacity Definition in LTE as Operator level A commonly accepted definition of capacity is the one provided by Shannon which states that capacity is the maximum achievable set of rates in multiple access channels with an arbitrarily small probability of error. As this metric represents a bound in performance, in practice, the sum of the … Read more
