What is a "Mobile Phone Signals"? The Most Authoritative Explanation.
What is a mobile phone signal?
A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink ). 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 communicate?
Signal reaches a cell phone to facilitate communication in essentially the same manner that two-way radios communicate — via a signal transmitter and a signal receiver. When you’re talking on a cell phone, it converts your voice into a signal that is transmitted via radio waves to the nearest cell tower.Where is a strong mobile phone signal most likely to occur?
Generally, a strong mobile phone signal is more likely in an urban area, though these areas can also have some "dead zones", where no reception can be obtained. Cellular signals are designed to be resistant to multipath reception, which is most likely to be caused by the blocking of a direct signal path by large buildings, such as high-rise towers.What is a good cell phone signal strength?
Cell phone signal strength is measured in decibels (dBm) that are received by a mobile phone from a cellular network. Signal strengths usually range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. Any signal that measures better than -85 dBm is considered to be a good cell phone signal strength.
