Actually the 4g signal [especially of 2300MHz band 40 one] will be good outdoors and there will be just indoor coverage issues especially in tall buildings, concrete jungles. Since the rooftop device will be placed outdoors on a tall post, facing the RJio towers with line of sight, it will get good signals for sure. That equipment will be connected to a power adapter plus wireless router inside home, so that 4g data can be shared by all inside the building as Wi-Fi. If your home has bad indoor coverage, then the router [Wi-Fi] serves to solve the issue using jio join and/or VoWiFi. Thus the outdoor unit serves like a small cell, even though it's not really is, thanks to Jio join and/or VoWiFi. sent from my Lenovo Vibe P1 using Tapatalk
