A hydrogen fuel cell vehicle is two to three times more efficient than a gasoline or diesel vehicle, according to the U.S. Department of Energy. They are quieter and have a lower heat signature ...
A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.
All of the cell sites are connected to telephone exchanges (or switches), which in turn connect to the public telephone network. In cities, each cell site may have a range of up to approximately 1 ⁄ 2 mile (0.80 km), while in rural areas, the range could be as much as 5 miles (8.0 km). It is possible that in clear open areas, a user may ...
Mobile cell sites are infrastructures transportable on trucks, allowing fast and easy installation in restricted spaces. Their use is strategic for the rapid expansion of cellular networks putting into service point-to-point radio connections as well as supporting sudden increases in mobile traffic in the case of extraordinary events (trade ...
A macrocell or macrosite is a cell in a mobile phone network that provides radio coverage served by a high power cell site (tower, antenna or mast). Generally, macrocells provide coverage larger than microcell. The antennas for macrocells are mounted on ground-based masts, rooftops and other existing structures, at a height that provides a ...
The ACLU's argument focused on the potential of cell site data to reveal sensitive information about a person's location. [1]: 608 It argued that cell site data information can track people while they are inside their homes, which the Supreme Court has held to be a constitutionally protected space.
A telecommunications lease is a lease that exists between a telecommunications provider, or a wireless company, and a landowner. Similar to other real estate leases, a telecommunications lease is put in place as an agreement to lease space on the landowner's property for a telecommunications site or cellular tower for a specified length of time.
Cell phones communicating with a single cell tower constitute a local subnetwork; the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the internet service provider's network (via a point of presence). A backhaul may include wired, fiber optic and wireless components.
