Kurs Titel:

LTE Planning and Optimization for Roll Out

   

Bestell-Nr.:

TA-TC 6430

   

Dauer:

5 days / web session 5x4 hours

   

Zielgruppe:

Engineers working in E-UTRAN planning, performance monitoring and optimization department as well as experts for technology swaps and upgrades.

   

Zielsetzung:

The workshop will support the participants to shorten the LTE roll out phase. They will get a deep understanding of the initial planning and the related parameter settings, as well as of the performance monitoring of the air interface and user experience required during roll out within a multi-vendor environment. Additionally the reuse of existing 2G/3G sites will be discussed, and how one can predict the LTE performance on basis of the 2G/3G performance at such reused sites. Optionally OSS life data of the customer�s network will be discussed, which are summarized as report. TECHCOM will analyze a cluster of 100 eNodeBs on the basis of the vendor specific OSS statistic. In dependence on the availability of timing advance counters, air interface performance (RSRP, RSRQ, CQI) and user experience (throughput, BLER) will be analyzed with a geographical accuracy better than cell level. Optionally OSS life data of 2G/3G sites to be reused for LTE will be analyzed as well, and the expected LTE performance will be discussed. This analysis will cover 1 BSC/RNC area.
