What base station antenna configuration is best for LTE Advanced?
In most scenarios, users are predominantly distributed in the azimuth plane, so, in the narrowly spaced, horizontal configuration, base station antenna (BSA) is clearly the best all-around antenna.
How do I aim my 4G antenna?
You should aim the outdoor antenna in the direction that best receives the signal from your carrier because a Yagi antenna will not receive any signal that is out of the direction they point to. In other words, if your carrier is out of the beam of the antenna, you won’t receive the boost you’re looking for.
Does 4g LTE use MIMO?
MIMO, Multiple Input Multiple Output is used within LTE to provide improved signal performance and / or improved data rates using the multiple path propagation.
What is UL MIMO?
UL MU-MIMO is an important feature introduced in Wi-Fi 6. UL MU-MIMO uses the multi-antenna technology of the transmitter and receiver to transmit data simultaneously on multiple spatial streams over the same channel. Multiple data streams in UL MU-MIMO come from multiple users.
How far apart should LTE antennas be?
2.2 Simple Wavelength Calculation This simple calculation shows us that if we are deploying 2.4 GHz antennas, they should be spaced at a minimum of 4.92 inches apart as a starting point to prevent coupling or other issues.

Is MU-MIMO better than Wi Fi 6?
Wi-Fi 6 (802.11ax) leverages the multi-user version of OFDMA and MU-MIMO for better efficiency of uplink and downlink transmissions.
What is difference between CA and MIMO?
Just focusing on the comparision between MIMO and CA, you can say ‘MIMO is the transmission of the multiple data stream within one eNB(BTS) via a same frequency and CA is the transmission of the multiple data stream using multiple eNB(BTS) with each eNB having different frequencies.
What are the different types of smart antennas?
There are two basic types of smart antennas viz. phased array and adaptive antenna array. Phased array type consists of either number of fixed beams with one beam switched on towards desired signal or a single beam which is steered toward the desired signal. It is also referred as multibeam antenna.
What are the advantages of adaptive smart antennas?
• Higher Gain for desired signal in the direction of interest. • Phased array smart antenna reduces probability of interference with narrower beam and adaptive array adjust the beam pattern to suppress the interference.
What are the advantages of phase array smart antenna?
• Phased array smart antenna reduces probability of interference with narrower beam and adaptive array adjust the beam pattern to suppress the interference. • It also helps in multipath mitigation which supports three types of antenna diversity viz. spatial, polarization and angle diversity.
What is the best angle to rotate an LTE antenna?
Rotate the antenna in about 45-degree steps and wait for the signal to stabilise at every step. Test over 360 degrees even if it seems stupid – LTE uses MIMO and reflections from unexpected directions can actually enhance speed. Find one “best angle” and another at least 90 degrees away from where you also get a reasonable signal.
