It picks up and transmits signals. Today antennas are built into the case with the battery and electronic parts. A few years ago these were exposed on the out side of the case.
On some phones it is possible to add an external antenna, to aid use inside a vehicle.
Yes there is. The position of the antenna is different on every phone. Like the Iphone it is on the outer side of the phone if placed to your ear. If you removed the casing on a blackberry you will see a gold antenna . If you remember the old cell phones with the pull out antenna, all it is, is an internal antenna instead. Hope that helped!
How do you use a mobile CB antenna for base station antenna?
Answer: No. Previous generations of mobile phones used the dipole antenna. (Some protruded, others were retractable.) A mobile phone must work in any orientation, so the antenna must be omnidirectional.
Answer: The modern mobile phone uses a fractal antenna. History: Previous generations of mobile phones used the dipole antenna. (Some protruded, others were retractable.) Details: A mobile phone must work in any orientation, so the antenna must be omnidirectional. Today's various cellular networks have multiple frequency bands. Smart phones have a variety of protocols (GPRS, PCS, Bluetooth, near-field, Ant, WiFi) requiring several transmitters and receivers working at a wide range of frequencies. Fitting two of more antenna in the same case increases complexity and costs. The only single antenna that can handle all these demands is fractal, thus, the entire industry now uses one or another style of fractal antenna.
Verizon has more then one antenna...
It's safer to hold a car antenna. The car antenna is a receiver only. The mobile antenna both sends and receives. It transmits calls, texts & data using microwave energy (similar to the energy found in microwave cookers). Although the 'jury is still out' it's speculated that long-term exposure to microwave energy can cause tissue damage.
The Virgin Mobile antenna booster gives you a better signal in your home by virtue of its large antenna.
Mobile phone tracking refers to the attaining of the current position of a mobile phone, stationary or moving. Localization may occur either via multilateral of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower.
A mobile phone is, as the name implies, mobile. It can be taken with you outside the car with you. A car phone is hard wired into the car, and cannot be taken outside the car. They both use the same technology and use the same cells. The car phone can be bulkier, have an outside antenna and use the car battery for power.
In a mobile device, the battery (chemical energy) converts into electrical energy to power the device. When the phone is being used, the electrical energy powers the various components of the phone, such as the screen, processor, and antenna.
Just about anywhere !.. In towns & cities - they're placed high up on tall buildings or self-standing masts. The mobile phone network uses microwaves to relay the calls - so it needs 'line of sight' from one mast to the next.
