2G,3G,4G- Reliance jio Antennas

In this post we are going to discuss about the 2G,3G and 4G ports and Antennas used in Reliance Jio project and how to Identify them.
As in earlier topic you have seen there are two types of Antennas used Ace & Rosenberger

How to distinguish between Ace & Rosenberger Antennas

1. By checking the Port order.
2. By checking the frequency bands on antennas.
3. By checking the RET position.

RET is known as Remote Electrical Tilt.

RET position in Rosenberger Antenna for Multi Band is side by side, whereas in ACE the RET position is top & bottom.

RET position in Rosenberger Antenna for Single Band is above the ports, whereas in ACE the RET position in the same line of the ports.

 SIDE BY SIDE RET- Rosenberger Antenna multi Band

Top & Bottom RET- Multi Band antenna

RET Above the Ports- Rosenberger Single band Antenna

RET in same line as ports- Ace single band antenna

Introduction to RF Antennas used in Reliance jio Installation project

Introduction to  RF Antennas, RET:

Jio uses the equipments of Samsung company and is manufactured in korea. There are two different type of brands of Antennas:

1. Ace
2. Rosenberger

Further Ace & Rosenberg Antennas are divided into separate Bands as follows

1. Single Band
2. Multi Band
3. Penta Band

Single Band:

      In Single Band the antenna is used only for one frequency band and that is only for 850Mhz, but the port order varies. .

Multi Band:

      In Multi Band the antenna is used only for two frequency bands and that is 1.8Ghz & 2.3Ghz but port order varies.

Penta Band:

      In Penta Band the antenna is used for all three frequency bands and that is 850Mhz, 1.8Ghz & 2.3Ghz but port order varies.

There are 3 Frequency Bands:

1. 850 Mhz  (2G)
2. 1800 Mhz (3G)
3. 2300 Mhz (4G)

Ace Antennas:

SINGLE BAND (850Mhz)

MULTI BAND (1.8Ghz & 2.3Ghz)

Rosenberger Antennas:

SINGLE BAND (850Mhz)

MULTI BAND (1.8Ghz & 2.3Ghz)

RET ( Remote Electrical Tilt):

There are two ways to tilt the antenna:

1. Mechanical Tilt - The coverage area is increased in side direction but reduced in central direction.
2. Electrical Tilt  - The coverage area suffers a uniform reducation in the direction of antenna azimuth, the gain is also reduced uniformly.
