Dear James,
I am glad to see OpenSignal begin to step forward to LTE while you are success in GSM/WCDMA already.
I believe while you said China, in this post, it is metioned for China HK, since July, Now All 3 China Mainland Operators, China Mobile, China Unicom, China Telecom, start their 4G jourery to mass commercial so fast. I am one of 4G lovers, interesting on the 4G coverage in RF bands.
I think I can contribute the data for South China cities such as in Shenzhen, Dongguan, Guangzhou,Huizhou.
I also have some workmates in Shanghai, Ningbo,Chengdu.
I am expecting your next generation app can works for 4G, both in LTE/GSM Auto Mode,LTE(TDD)/TD-SCDMA/GSM Auto Mode, LTE only Mode,LTE/CDMA Auto mode for China Operators.
I know there is firmware issue in Chipset vendor Qualcomm current Platform,let us both push Qualcomm to make it better.
I will send you another mail for some attachment for Some 4G MNC,GCI Coverage in China Mainland.
