Product Description:

It is a radio unit of Ericsson, with the model number 2217B20 and the part number KRC 161 549/1. It is applicable to wireless base stations and supports 2G/3G/4G networks

1.Technical Specifications

• Frequency Band: It operates in FDD Band 20 for LTE, with a frequency range of 718 - 748 MHz for the uplink and 773 - 803 MHz for the downlink.

• Output Power: The maximum nominal output power can be 2 x 10 W, 2 x 20 W, 2 x 30 W, or 2 x 40 W. A license key is required for a total output power over 20 W.

• Carrier Capacity: For WCDMA, it supports one to eight carriers in Band 1, one to seven carriers in Band 8, and one to five carriers in Band 5. For LTE, it supports one to three carriers. In mixed - mode, it supports two to six carriers in Band 1, two to seven carriers in Band 8, and two to seven carriers in Band 5 (HWAC required).

• Antenna Configuration: It is a 2T/2R radio, which means it has 2 transmit antennas and 2 receive antennas. It provides in - built support for MIMO and TX diversity as well as RX diversity through two duplex (TX/RX) branches.

• Interface: It is equipped with optical interfaces for high - speed data transfer to the baseband unit and electrical interfaces for power supply and control signals.

2.Physical Characteristics

• Dimensions: Without the fan unit, the dimensions are 351 x 298 x 127 mm. With the fan unit, the dimensions are 351 x 298 x 138 mm.

• Weight: The weight without the fan is 12.3 kg.

3.Functional Features

• Signal Processing: It performs functions such as modulation, demodulation, and encoding/decoding of radio signals in the Band 20 frequency range. It also participates in functions like beamforming in a MIMO system to improve the overall system performance.

• Network Integration: It works in conjunction with other components of the mobile network, such as the baseband unit and core network elements, to enable seamless communication between mobile devices and the network. It helps in managing radio resources efficiently and ensuring smooth hand - overs between different cells.

4.Installation and Deployment

• The radio 2217 is preferably located near the antenna and can be located up to 40 km from the baseband unit. A fiber - optic cable is used to connect it to the baseband unit, and several radio units can be connected in a cascade or star configuration.
