Mobile Network Optimization

There are many uncertainties in mobile communication, and these factors have a great impact on mobile communication networks. Thus the continuous network optimization is needed to improve the reliability and availability of the mobile network. It not only improves the quality of services for end users but also brings significant and long term economic benefits for the mobile service providers and the whole industry.


Mobile communication network becomes more and more complex and operators are providing full services to the end users. But problems arise:

l Bad mobile communication signal distribution

l Low rate of call setup, High rate of call drop

l Low quality of voice and data services

l Customers’ complaint concentrated upon indoor coverage

To solve these problems, the mobile networks should be carefully assessed, evaluated and tested and afterwards take optimization engineering to have better outdoor/indoor coverage to improve the performance of the networks and reduce the end customers' complaint. To achieve this goal, 3 main tasks need to be executed:

l DT and CQT assessment for voice and data services of 2G/3G/4G and futrue 5G networks

l Test data analysis and optimization planning

l Network coverage optimizing (Outdoor and Indoor Distribution)


Sunstar provides total network optimizing solution i.e. we provide professional services incl. site survey, DT & CQT, network planning and network optimizing etc. relies on our great capabilities of R&D and rich project experience while providing network optimizing related products and systems.

The Indoor Distribution System (IDS) can comprehensively improve the voice and data communication quality within the buildings e.g. residential houses, offices, malls, stadium, airport and underground parking etc. The use of micro cell can share the outdoor macro cell traffic to expand network capacity, reduce the network congestion, and improve the overall mobile network service level. IDS can adopt different types according to different scenarios:

Passive RF IDS

Active RF IDS
Optical Fiber IDS (MDAS)
Leakage Cable IDS
and macro cell, micro cell, BBU+RRU and repeaters can be used  as signal sources of IDS.

The passive RF IDS and MDAS are often used by the global mobile network operators:

l Signal source: BTS/eNode B/Micro Cell/BBU+RRU/Repeater

l Main components: combiner, coupler, splitter, duplexer, attenuator,

load, omni indoor antenna, panel antenna, RF cable etc.

l Signal source: BTS/eNode B/Micro Cell/BBU+RRU/Repeater

l Main components: MAU, MEU, MRU, optical fiber, RF cable etc.

Typical scenarios:

Underground Parking(Repeater)

CBD Office (MDAS)
