What is iREAS

intelligence •Integrate kinds of radio factors together to analysis problems•Smart module can automatically output the issue lists and suggestions

Radio Focus on Radio layer, the most complex layer, the changeable layer

Expert •Combiner RF experts’ experience and advance algorithm•Care potential issues and root causes.

Analysis •Different level analysis: network level, cell level ,grid level•With Smart analysis module and dedicated analysis module

System •It is solutions: can give out suggestion •It is service : including kinds of dedicated evaluation/audit/optimization service

Mostly RF optimization software which usually care of the statistic results ， e.g. the KPI of OMC statistic, the events during DT/CQT, etc. But they scare efficient way to analysis what is the root causes lead to the results. Since they cannot solve the issue from the root, the optimization service usually cannot meet the customer purpose even though bring new issues during the service.

iREAS innovate the idea how to audit ,analysis and solve the radio network issues. iREAS can easily find out and focus on the root elements of the radio network, Data analysis dimensions adopt 50M*50M GIS grads, integrated the expert experience algorithm. iREAS can bring the truth improvement of radio network KPI and subscriber QOS through solve the issues from the root.

2 iREAS Service Solutions Case

2.1 Construction （ Overlap LAC ）

This area is cover by two cells with different LAC, but here is not the LAC edge,So it is a OVERLAP LAC ,we should take care

2.1Construction （ Dual band ）

The above is the dual band system coverage picture, through overall analysis to dig the network potential capacity.

2.1 Construction （ Dual band ）

There is bad quality In the cross arrow area, but after analysis ,we suggest DCS1800 take the service in this area but not the GSM900

DCS1800 is better

2.2 Coverage （ coverage hole)

We use different coverage analysis method to find more potential issues

2.2 Coverage（ Indoor overshoot)

Indoor overshoot may take interference to others , iREAS can quickly outputThe overshoot cell list and give some suggestion

2.2 Coverage（ outdoor overshoot)

Cell a cover the more grids faraway from the cell location, it overshoot the Cell b, Cell a is a site with over 50 meters height.

2.2 Coverage（ overlap)

More cell cover the same grid, it is not a good coverage distribution

The above is the single cell abnormal coverage

2.2 Coverage（ Abnormal coverage)

2.3 interference（ co/adj -channel)

Can find where exist co/adj-channel interference, and will give outthe reason and the solutions

2.4 Voice quality

Except the interference , we will analysis speech rate, ho factors to overall Analysis how to improve the voice quality

2.5 Event list

iREAS can show all event list which can show in other tools

2.6 cell analysis

The above is a single cell coverage picture and the related information of this celliREAS can show any cell overall information

2.7 UMTS Coverage

iREAS can show Coverage of the UMTS network.

2.8 UMTS quality

we will analysis how to improve the voice quality and PN planning.
