Hello. I need to boost my cellphone (mobile) signal not my wifi . I looked at a large parabolic antenna to be outdoor mounted and thought that might be the answer. But the instructions showed it being plugged into the antenna port on the router and said it would boost the wifi signal. I do not want to do this but simply want to boost the signal coming from the tower so I will have reliable internet without wifi. If this is the case, can the parabolic antenna be used to do this? If so, how does it integrate with my phone to boost the signal from the cell tower? Is there another device involved with a different kind of antenna, assuming the parabolic antenna only be connected to the router to boost wifi for better coverage inside the building? Thanks in advance.
