Cell Phone Coverage Problems

Cell phones have great significance in modern society. Cell phones are our lifelines to the world and they allow us to stay connected at all times. Due to the increased prominence of cell phone, wireless providers now offer extensive coverage areas that encompass the majority of the U.S. However, despite the extensive coverage map, there are a variety of factors that impair wireless coverage.

Function
Cell phones communicate with a series of towers or "cell sites" to send and receive voice calls across public telephone networks. Since wireless telephones use radio waves, their coverage is impacted by a variety of factors, including location of cell phone towers, call volume, architecture and topography. These factors can limit wireless coverage within a wireless provider's coverage areas and often result in dropped calls, poor call quality or weakened signals.

Cell Phone Towers
Cell phone towers are essential to the successful transmission of cell phone calls. Despite an abundance of cell phone towers in a given area, callers may experience dropped calls due to their location and the number of callers accessing the network. Traveling between cell phone towers and driving through tunnels causes cell phone calls to drop because they inhibit the successful transition of the call from one tower to another. Additionally, a high volume of cell phone callers accessing a tower at a given time strains the provider's network. A strained cell phone network results in a busy signal and inhibits the ability to place a call.

Architecture
The type of building in which you are located also influences the reliability of cell phone coverage. Buildings are generally constructed with dense materials that impair wireless reception in coverage areas. For example, concrete greatly reduces wireless coverage because its thickness absorbs or blocks the signal. Aluminum siding and stucco also impact wireless coverage because they reflect radio waves and inhibit them from reaching the cell phone. In these instances, installing an antenna on top of the structure or going outside of the building may be necessary to successfully place or receive calls.

Electromagnetic Interference
Electromagnetic interference disrupts the reception of radio waves and prohibits cell phone towers from properly communicating with cell phones. Electrical and battery-operated items that can be found within a home or office can cause cell phone interference. Microwave ovens, blenders and computers can cause interruptions with cell phone service. When placing a call, it is recommended that you move away from these items or unplug them.

Geography
The geography in a given area can greatly impair or disrupt cell phone coverage. Mountains, hills, dense trees and tall buildings interfere with cell phone service because the phone and cell phone tower are blocked from communicating with one another. When the cell phone signal does come through, it is often distorted and unclear. When traveling through areas with hills and trees, it is recommended that you place your phone at an angle when you reach a clearing to help the cell phone tower find your phone. The problem is being curtailed in cities since many buildings now have cell phone towers installed on their roofs.
