2.4.1 MIMO & Dual Polarization
What is MIMO:
With the rising data rates and signal congestion, the MIMO is the proposed radio technology in IEEE 802.11n and accepted popularly. MIMO is short of the Multiple-Input and Multiple-Output, is the use of multiple antennas at both the transmitter and receiver to increase the wireless communication bandwidth, for example the 2T2R means 2 Transmitter and 2 receiver, then the bandwidth is double than SISO. MIMO technology offers significant increases in data throughput without additional bandwidth or increased transmit radio power.
The below figure shows the SISO technology, each transmitter and receiver has single radio.

The below figure shows the MIMO technology, the transmitter and receiver spread the total transmit power to 2 (or more) different radio antenna for communication.
What is Polarization:
Polarization is a property of wireless antenna, the polarization determines the antennas that can pick up the signal, for example you can set up two antennas in close and pointing to the same direction, but with different polarization. The result is only antennas with the same polarization will be able to communicate with each other, this is important especially in point-to-pint wireless communication.
There are two major polarizations, Vertical and Horizontal. The antenna may support either one, you can choose Vertical or Horizontal polarization for the antenna installation. The result would be that antenna which is vertically polarized would only receive the signal from the vertically transmitting antenna, horizontally polarized antenna would only receive horizontally transmitting antenna. The below figures show the typical Horizontal / Vertical polarization:
Horizontal Polarization
Vertical Polarization
Dual Polarization:
There is also Dual Polarization antenna which provides two ports to plug in, one for the vertical and the other for the horizontal polarization. The dual polarization antenna can communicate with antennas of both types of polarities at the same time from one antenna. The below figure is the example of Dual Polarization connectors. There are 2 ports, one is for

Vertical polarization, and the other is for Horizontal polarization. While installing the antenna, the 2 ports direction of the 2 end must be the same.
MIMO & Polarization:
To reach the 2T2R MIMO high performance, the antenna with dual polarization (also known as DP) which supports both vertical and horizontal polarization is necessary. While you select the external antenna, check the polarization specification of its datasheet or check with the supplier.
Normally, there are 2 connectors of the dual polarization antenna, this is also a way to identify whether this is dual polarization or not. Connect the 2 end of the antenna to the antenna socket of the Access Point. The below figure shows the dual polarization transmitting between the 2 MIMO antennas:
2.4.2 Antenna Socket
The JetWave 4020/4020E Series supports IEEE 802.11n and 802.11ac 2T2R MIMO technology. There are. JetWave 4020 series is embedded antenna that you dont need to mount external antennas. JetWave 4020E series is external antenna model, it equips 6x N-Type antenna sockets for two WIFI radio (2x sockets by option), you can connect 1 to 6 WIFI antennas based on your need.
If you just need to connect one single polarization WIFI antenna on JetWave 4020E, you must go to the Web GUI to change the antenna number to 1 (The chapter 4.4.3 for reference),

and connect it to the 1st antenna socket, Radio 1-1(A) or Radio 2-1(C) of the JetWave 4020E. Please remind that it is just 1T1R (150Mbps) in such installation.
If you would like to connect dual polarization antenna or 2 antennas for 2T2R, you must connect to the two antenna sockets, Radio 1-2(B) and Radio 2-2(D).
2.4.3 Antenna Installation
The figure shows the direction to lock the antenna, it is clockwise direction. There is Nylock pasted on the antenna to avoid antenna loosen in vibration environment, please don’t often lock/un-lock the antenna, otherwise, the Nylock paste will be damaged. Use the same way to lock the attached WIFI antenna, it is clockwise direction as well.
Note that the counter-clockwise direction will loosen the antenna immediately.
For vibration environment, we dont recommend you connect the antenna directly to the
device, no matter how heavy you lock it. It is suggested you install the antenna at non-vibration or low vibration place and connect it by extended Radio cable antenna to the device. In another practical case, we usually mount the device within the field box to protect water, rain

or other reasons, and mount its antennas outside the box. This is because the radio signal MUST be filtered by the metal field box if you install the AP within the box. Korenix provides the external antenna mounting kit, extended radio cable, celling mounting kit as optional accessory. While you need it, you can purchase from Korenix. For how to mounting the antenna plate and celling-mount plate, please refer to the chapter 2.6.
