8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.
Thus, the frequency band dedicated to TV became between 470 MHz and 700 MHz (channels 14-52), whilst 4G LTE uses the frequency bands between 700 and 900 MHz (former TV channels 52 to 83), resulting in an interval separating the two bands (DTT and 4G) of about 1 MHz, so that there is a risk of interference [1] in the areas close to the 4G-LTE ...
Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables.As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point, cabling run, and antenna.
In an ideal communication scenario, there is a line-of-sight path between the transmitter and receiver that represents clear spatial channel characteristics. In urban cellular systems, this is seldom the case as base stations are located on rooftops while many users are located either indoors or at streets far from base stations.
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.
Outdoor antennas provide up to a 15 dB gain in signal strength and 15-20 dB greater rejection of ghost signals in analog TV. [6] Combined with a signal increase of 14 dB due to height and 11 dB due to lack of attenuating building walls, an outdoor antenna can result in a signal strength increase of up to 40 dB at the TV receiver.
