Site SelectionHow to process so many candidate sites and so large areaHow to priority covered POI

Site Selection PrincipleInter site distance following network design result.Preference for the existing base stationTry to select the ideal honeycomb structure of the siteThe selected site should be close to important areas and dense areasAntenna must have enough isolation space to avoid interference between systemsTry to avoid select very high build or hill as site address in urban area

Manual site selectionWe found tool has obvious limits in term of balancing between threshold, coverage, traffic load, cost of sites etc. Manually adjust the result is necessary.Network design result:Cell rangeInter site distance

LTE Spectrum Defined by 3GPP

Different bandwidth and antenna, different speed

Spectrum efficiencyA comparison between different bandwidth

Conclusion: Its a little different between different

Spectrum efficiencyA comparison between different MIMO mode

Conclusion: The spectrum efficiency will increase if antenna increases.

Spectrum efficiencyA comparison between different frequency

Conclusion: The spectrum efficiency will be different in different frequency. With the increase of frequency, the spectrum efficiency decreases, especially when in a large scale difference.
