Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
People can interact with a DTV system in various ways. One can, for example, browse the electronic program guide. Modern DTV systems sometimes use a return path providing feedback from the end user to the broadcaster. This is possible over cable TV or through an Internet connection but is not possible with a standard antenna alone.
Many antennas marketed for digital TV are designed for UHF, which most digital stations use. VHF analog signals travel further than UHF signals, but watchable VHF digital signals appear to have a more limited range than UHF with the lower power they are assigned, and they do not penetrate buildings as well, especially in larger cities.
OTA antennas are digital receivers that pick up signals broadcast by local TV towers, allowing you to watch local programming without cable. These antennas cost anywhere from $15 to $50.
To use Xumo, you need to be a Spectrum cable TV subscriber and a Spectrum internet customer. Currently, most Spectrum customers get cable TV access through what’s called a “set top box,” or ...
A 'whip' antenna at the side of a Casio portable TV. Some portable televisions use a whip antenna. [6] This consists of a single telescoping rod about a meter (3.3 feet) long attached to the television, which can be retracted when not in use. It functions as a quarter-wave monopole antenna.
In the United States, television is available via broadcast (also known as "over-the-air" or OTA) – the earliest method of receiving television programming, which merely requires an antenna and an equipped internal or external tuner capable of picking up channels that transmit on the two principal broadcast bands, very high frequency (VHF) and ultra high frequency (UHF), to receive the ...
Jul. 21—MANKATO — The planned arrival this year of a new high-speed internet provider in Mankato fell through, but a second existing provider is now bumping up its speeds. Charter Spectrum ...
