Factors Affecting Throughput in LTE :- Low mcs, Low sinr, Low rsrq , high prb usage, wrong earfcn Definition, no Carrier aggregation ör missing ca configuration, Pci , Route sequence index collision, Wrong tac planning, gateway security problem, etc. air quality (now sinr, rsrq, etc etc), modulation level. For example, 16QAM, 64QAM, etc. Low Throughput Issue:- 1 - Poor coverage (BLER) 2 - Availability issue 3 - Uplink Interference 4 - A poor RACH decoding SR 5 - High error on S1 link. 6 - Delay on S1 link towards MME & SGW. 7 - Accessibility issue. 8 - Handover failure. 9 - Lack of PRBs. 10 - Problematic UE. 11 - Downlink Interference (Bad CQI) 12 - MIMO Parameters 13 - High VSWR 14 - High radio errors or instability issue. 15 - Maximum number of RRC connections active per cell 16 - Maximum number of users per TTI supported per cell. 17 - Core network, MME/SGW, etc 18 - Transmission instability & bottleneck. 19 - Incorrect parameter setting. 20 - Badly tuned handover parameters...
Hi All
It is seen that Telecommunication is ever growing field.
I saw a lot of freshers who are looking for jobs and having interest to get entry in Telecom.
My first intention to introduce them about the Cellular Technology and their future aspects.
It will be just like a online free training program of freshers as well as for Experienced engineers also.
I can say that Objectives of this blog are

Junior engineers who already had a entry in Telecom
Basics & fundamental review
RF survey, transmission surevy
Drive Test and field Optimization tips
troubleshooting of live problems
RF Planner and Optimizers who are currently working on 2G, 3G and wimax
Planning 2G,3G, 4G, LTE and wimax
Optimization
BSS Parameter planning and live troubleshooting of multi-vendor systems.
Job search for Freshers and Experienced Engineers
To Aware all about National and International jobs on permanent basis, short and long term contracts. And for freshers possibilities and consultancy to application.
I request all of my telecom colleagues to provide the best data to publish here and suggestions to make it better.
