I think we need to see more info about the cell towers to understand the implications more fully. Midtown Manhattan is very busy, and apparently RH's house is within a short distance from the LIRR train station, which would also have traffic. IMO, the evidence, until we know for sure, has to do with LIRR train stop approximate locations, along with Midtown/Penn Station or Port Authority area. I would like to see a map, in future, of the Long Island Pings.
I am not sure why Massapequa/Massapequa Park area has been so heavily focused on. For a second, imagine RH was not apprehended, yet. Why has Babylon/West Babylon area not received more scrutiny? Two of the four Gilgo 4 had ties to those areas right before they disappeared.
MBB: around 59th St. Bridge (Manhattan, going toward LI City/Queens area), then later out by LIE, Islandia, LI
MB: pings corresponding to areas along LIRR routes, and her phone was used corresponding to cell sites in Babylon
MW: Hauppauge, activity in Massapequa Park (again, RH's house is close to train station)
AC: house in West Babylon area
To make matters more confusing, relying just on paperwork (not interviews) since RH's arrest, I want to see an explanation in the future as to why MB's date of disappearance/last seen has been changed on the bail doc. Add to that, none of the burner phones used to contact the victims were known to be owned or operated by RH.
