the correct answer is single direction
Single
The correct adjective form for the noun direction is 'directional'. However, the word direction is used casually as an adjective, for example 'direction signals' or 'direction markers', but they should be 'directional signals' and 'directional markers'.
A wireless adapter that uses a universal serial bus (USB) connection gives a business the flexibility to make any computer or laptop a part of the wireless network. A wireless USB network adapter relies on a limited amount of power when it is attached to a laptop or other device. This can sometimes restrict the range of the adapter. One way to extend the range is to change the antenna on the unit. A wireless USB network adapter uses some type of antenna to send and receive signals. This antenna can often be removed and replaced from the unit. The most common type of antenna on a wireless USB network adapter is an omnidirectional antenna that receives signals in all directions. A much stronger connection can be maintained across a longer distance with a directional antenna that focuses on signals coming from a specific location. These antennas are inexpensive and very effective in an office environment. Unfortunately, this will not work with a wireless USB network adapter that contains an integrated fractal antenna that cannot be replaced.
An Omnidirectional antenna generates a beam in all directions and is defined as one "having an essentially non-directional pattern in a given plane and a directional pattern in any orthogonal plane". A Smart antenna however, often referred to as an adaptive antenna, utilises adaptive DSP based techniques and digital technology. The original analogue signals must be converted to digital form through the use of digital converters. Consequently, the nulling of a given interference and the steering of the main beam to a known direction can be achieved by changing the phases and amplitudes of the signals in individual elements of the array.
they dont. An antenna is simply a piece of metal hooked to a device (normally a radio or a walkie-talkie). A receiver (for example, a radio) pick up electrical signals from the antenna, and a transmitter sends them to the antenna. They can be combined to form a transceiver which then sends and receives signals from the 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.
An omni directional antenne receives or transmits signals from all directions as in 360 degrees. A directional antenne is aimed in a specific direction so that it may direct an outgoing signal to or receive a signal from a specific source.
high speed internet that uses an antenna on a house or business to communicate with a tower location via radio signals.
It sends and receives radio signals to and from other wireless devices. Similar to a CB radio only in computer language.
In Electomagnetics, Radio, Electronics, etc.:An antenna is a structure that couples energy between a circuit (radio, cell phone, etc.) and free space. The plural is antennas.In Biology, Zoology, etc.:An antenna is an organ used to sense the surroundings. The plural is antennae.
it receives signals and sends out signals
You should buy an omnidirectional antenna with a high gain (measured in dBi) if you have a wireless G or B router. If not, I recommend you to buy a wireless N router that comes with 3 antennas. It really increases your signal strength and range. You don't need to have a wireless N adapter to use it, as it supports the older modulations
