what is cell phone signal?

Filed under: Signal Academy — Tags: , , — 3:57 pm

A mobile phone signal is the signal strength received by a mobile phone from a cellular network. Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength will vary.

How does a cell phone signal work?

Whenever a cell phone is used, it emits an electromagnetic radio wave, called a radio frequency, that is received by the nearest cell tower’s antenna. Once the cell tower receives this signal, it will transmit the signals to a switching center.

What is a Cell Tower?

Cell towers, also known as cell sites, are where electric communications equipment and antennae are mounted, allowing the surrounding area to use wireless communication devices like telephones and radios.

Cell towers are usually built by a tower company or a wireless carrier when they expand their network coverage or capacity, providing a better reception signal in that area. Cell towers are basically everywhere across the United States, although some cities have more than others. And Millman Land was there since the late 1990s, ensuring that the cell towers are all properly inspected.

There are currently more than 307,000 cell towers in the United States. Sometimes they can be spotted on tops of buildings. Other times cities require cell towers to blend into the cityscape seamlessly. Rural areas sometimes hide them in treescapes, disguising them as a tree.

What Affects a Cell Tower’s Range?

The range of a cell tower is not a fixed figure. That’s because there are so many variables when it comes to the range in which a cell tower connects a mobile device. The most common variables include:

  • How hight the antenna is over the surrounding landscape.
  • The frequency of the signal in use.
  • The rated power of the transmitter.
  • The directional characteristics of the antenna array on the site.
  • Nearby buildings and vegetation absorbing and reflecting radio energy.
  • The local geographical or regulatory factors and weather conditions.

Cell towers are often built in areas with high population densities. That’s because these cities have the most potential cell phone users. For that reason, you’ll often find cell towers “overlapping” in more crowded areas. This helps to avoid interference problems.

If you find yourself wondering why you don’t have a signal on your cell phone, it could be because you’re too far from a tower or because the cell phone signal has been decreased by hills, large buildings or other structures. You may also lose your signal if a lot of people are attempting to use the cell tower at the same time. That often leads to calls getting dropped.

While driving, your phone can switch from one cell tower to the next mid-conversation. As you continue your journey, the cell phone will pick the strongest signal and release the weaker cell tower, making it available to another caller.

Another factor that could affect your signal is a problem with the cell tower. With help from surveyors like Millman National Land Service, these issues can be identified so they don’t turn into a major headache.

What determines cell phone signal strength?

Cellular signal strength is measured in decibels (dB), and typically range from -50 dB to -110 dB. The dB scale is logarithmic. This means that every 3 dB increase doubles the power. For example, -67 dB is twice the power of -70 dB.
