What Is Cell Phone Technology?

Cell phones have become a part of our everyday lives. We use them for calling other cell phones, for making calls, for messaging, for taking pictures and videos, and for many other uses. We no longer go directly to the phone and talk on it but instead use it while we are on the go. Some people even take their cell phones with them on a trip to allow for the possibility of a missed call. Cell phones are even used in some places for communication purposes during emergencies. This article will explore some of the latest types of cell phones that are available to the consumer.

Walkie-Talkies: These hand-held devices are commonly known as walkie-talkies and are an effective means of communication. A hand phone is capable of picking up transmissions from low-power, military or law enforcement radar systems. Hand phone users can also pick up frequencies from cell phones which are in radio range, although this is more difficult to do.

Cell Phone Boosters: Boosters are used to increase the strength of the signals being sent out by cell phones. A boost unit amplifies the transmission by adding extra channels onto the base station or by modifying the channels being used. The added channels result in stronger signals and more reliable reception.

Antenna Designs: Most cell phones use a standard single-sided dipole antenna. This antenna is designed with a series of tuned metal cones that are open at the bottom to allow for the insertion of a directional antenna. The advantage of the dipole is that the signal receives are stronger and more consistent than those received through a multi-sided, coupled antenna. However, a two-sided antenna is capable of receiving a strong, directional signal at much stronger strengths than a single-sided antenna can.

Low-Power Transmitters: Low-powered, or "hand held" cell phones often have a small, hand held transmitter and a built in base station. When the signal strength is weak, the handheld transmitter can be used as a personal radio. This type of personal radio will only receive a faint signal. When the strength of the signal is strong, the handheld transmitter can be used as an instrument to detect other, stronger signals coming into the base station. Most low-powered transmitters use their own internal antenna to boost their strength.

Cell phone technology continues to advance at such a rapid pace that many people don't even notice it anymore. New features are being added constantly as well as upgraded versions of older features. Cell phone companies are continuously trying to improve their products and offer more value to their customers. For cell phones this means better battery life, longer signal coverage and clearer sound during cell phone calls.
