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.
The Vodafone K5150 Vodem is a CAT4 4G device, capable of download speeds of up to 150 Mbit/s on a 4G LTE network [3] and 42.2 Mbit/s with a dual-carrier network. The Vodafone Pocket WiFi is capable of download speeds of up to 150 Mbit/s on a 4G LTE network [4] and 50 Mbit/s with a dual-carrier network.
Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...
A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.
Antenna for LTE MIMO technology with 2 connections of offset indoor antennas. Smart antenna research led to the development of 4G MIMO. Conventional smart antenna techniques (such as diversity and beamforming) deliver incremental gains in spectral efficiency. 4G MIMO exploits natural multipath propagation to multiply spectral efficiency.
The population in Fort Mill, South Carolina — home to PuckerButt Pepper Company, the original producer of the world's hottest peppers — once sat at 24,514, but has seen an increase of 37.2% ...
Supreme Court Chief Justice John Roberts slammed what he described as “dangerous” talk by some officials about ignoring federal court rulings, using an annual report weeks before President ...
Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1] A typical wireless router in an indoor point-to-multipoint arrangement using 802.11n and a stock antenna might have a range of 50 metres (160 ft) or less.
