Macro station of CMCC TD-LTE network is deployed in band D and band F. There are two kinds of handover: intra-frequency handover and inter-frequency handover

which are similar in handover progress. In intra-freqnency handover

SINR is relatively poor before handover while SINR improves greatly after handover. In inter-freqnency handover

because of frequency isolation

SINR is relatively stable and improves a little after handover

but the GAP of inter-freqnency measurement will take up some time. Both kinds of handover can improve the speed

but juding from a large number of test data

inter-freqnency handover show more speed improvement than intra-freqnency handover.
