I live in a two-bedroom condominium on the 33rd floor. I get 4G service according to the screen of my phone virtually all day long until I get home. I walk through the front door and my 4G service is reduced to 3G or 2G. There is literally one spot in my home that gets me 4G speeds; the absolute corner of my bedroom. I decided that it’s time to get on the fixed broadband bandwagon. Now, watching movies online, video chatting with my best friend, and gaming online for hours no longer makes me want to pull my hair out.
High- rise buildings are culprits of poor indoor reception, much of which stems from building materials such as wire mesh, electrical cabling, and metals. If there are other multi-storey buildings nearby, they too could be blocking the signal between the mobile towers and your device(s).
