Blocked Call – A wireless call that does not go through because the network is operating at maximum capacity. In this instance, a caller would hear a series of beeps indicating the call cannot be completed.

Capacity – The maximum number of voice calls or data traffic that a particular wireless facility can handle. Each wireless facility can only handle a finite amount of traffic at any given time.

Collocation – Locating the antennas of two or more wireless carriers on one facility (e.g. monopole); or locating a wireless facility on an existing structure (e.g. water tower or light standard).

Coverage Area – The geographic area serviced by a wireless facility.

Dead Spot or Dead Zone – A geographic area where there is no wireless coverage.

Distributed Antenna System (DAS) – A multi-structure wireless facility design consisting of multiple wireless nodes. The nodes are connected via a fiber optic cable or coaxial cable network to a hub. The wireless nodes can be attached to utility poles and other structures.

Dropped Call – A wireless call that disconnects or “drops” suddenly.

Enhanced 9-1-1 (E9-1-1) – An emergency service designed to provide additional protections for wireless phone users. Similar to the 9-1-1 service offered for wireline phones, E9-1-1 service provides the call-back number and approximate location of a distressed caller to emergency dispatchers.

Set is a one-time process; the phone connects automatically after that. Used at @ T-mo HotSpot locations* Use current mobile phone network*

Hub – A switching and control center on a DAS network where the necessary connections are made to permit wireless service.

Micro-cell – A compact, single- or multi-structure wireless facility that offers limited coverage and capacity to a particular geography.

Multi-structure Wireless Facility – A wireless facility where all necessary equipment is placed on multiple structures throughout a geographic area (e.g. micro-cell or a distributed antenna system).

Node – A low-capacity wireless transmitter/receiver typically placed on utility or light poles as part of a DAS network.

Search Area – A geographic area in which a wireless carrier seeks to place a new wireless facility to provide new or improved service.

Single-structure Wireless Facility – A wireless facility where all necessary equipment is contained on a single structure (e.g. monopole; also known as a macro site).

Traffic – The volume or flow of voice and data communication over a wireless network.

Wireless Facility – The antenna(s) and other equipment necessary to provide wireless service for a particular site. A wireless facility is also known as a cell site or tower.

Wireless Network – An integrated connection of wireless facilities that allow customers to send and receive calls and/or transfer data.
