problem with 4G is the lag and also it takes a lot more power streaming via LTE signals.. i wouldn't mind having a 3G/GSM system built in with a nano sim card for recovery purposes and tracking purposes.. that makes good sense, but modern day 4G cell signals are high latency for live streaming, lower latency for simpler work like packet testing and stuff... also have to consider the amount of data that will consume.. spark's video stream is about 875KB/Sec spark -> RC- > Phone. so 40 minutes of 875KB/Sec = 2GB per flight.
other issue is alot of deadspots... where i fly sometiems is basically deadzone for most carriers... and sometimes just better to have direct control..
ontop of that i think for size of the spark.. 20 minute battery is more reasonble...maybe 25 minutes.. even so.. still 1GB or more using 875KB/Sec for 20 minutes+
