As I’m walking to a meeting from the second level of a parking garage talking on my cell phone, I was impressed--the cellular service isn’t bad down here. I’m wondering whether the coverage is provided by a local tower close by or through a distributed antenna system (DAS). Now I’m curious about the coverage in the adjoining building….how good will that be? I need to contact a colleague and leave a short message before I head into my meeting, so I’m hoping the coverage inside is consistent.

Entering the building I see people on their cell phones in the lobby--that’s promising. Wait, one person is looking at his phone and moving toward the lobby windows. Not good. I check in with security and start to dial my colleague’s number before getting on the elevator. I hope there’s coverage in there. The doors close. I’m passing the second floor, now the third floor and then I hear a “hello” on the other end of the line--music to my ears!

Complete in-building wireless coverage used to be a luxury, but now it’s expected. Building owners are beginning to recognize that tenants and visitors expect seamless access to cellular networks both outdoors and inside. A well-designed in-building wireless system, or DAS, can be designed to augment the coverage and capacity offered by the outdoor cellular network. It should provide scalable, full-spectrum coverage of all of the carrier’s signals throughout the building or enterprise.

 How was the cell service in the buildings you recently visited?

Nathaniel, great article - up to this point, it's always been second nature to tell a caller I am entering an elevator, and I'll call them back when I get to my floor. Some of my clients had lower level offices and that triggered the same "no service" alert. I'm glad that building management is recognizing the demand for seamless connectivity!


Nathaniel has rasied a good point, however the challenge for in-building designers is to find a way to get coverage in lift cars. It is difficult (but not impossible) to install antennas in lift shafts. An alternative is to install at remote radio head, such as ION-B, on the lift car, but need a fibre cable in the trailing cable (another challenge). Traditionally, positioning an antenna in front of the lift in the lobby on each floor has worked, but a popular smartphone reciever performance limits coverage when the doors close....
