Product Overview
AIR 2488 is an antenna-integrated radio that consists of an active and a
passive part. The active part is one or two integrated 4-branch radio units,
single active AIR 2488 and dual active AIR 2488.
The passive part consists of a two column dual-polarized antenna. The exact
configuration of the antenna differs between the different product variants. The
active part is connected to an RBS main unit and is intended to be used in a
main-remote configuration in the same manner as conventional Remote Radio
Units (RRUs). The passive part of the AIR unit allows connection to an
existing RBS with the AIR unit functioning as a standard antenna. A typical
configuration is shown in Figure 1. Other installation alternatives are shown in
Figure 2 and Figure 3.

Antenna Integrated Radio Unit Description
2.1
Main Features
The AIR product is designed for outdoor installations, intended for pole, wall,
or mast mounting. The active radio section operates over LTE and GSM radio
access. The active section contains one or two 2TX/4RX RUs directly
mounted on the antenna section. Each RU is connected to the Digital Unit
(DU) or Baseband unit located in the RBS by one or two fiber optic interface
cables per RU, providing digital transmission and control of the RU.
The AIR antenna section provides both antenna arrays for active and passive
functions. The AIR passive section provides an isolated antenna connection
for an external RU operating from a non-related RBS. Interface connections to
an external RU are provided.
The AIR antenna supports multiple frequency bands which can be
independently tilted. The electrical tilt function is achieved by integrated
Remote Electrical Tilt (RET) units.
The AIR unit can also be mechanically tilted by using the down tilt installation
kit from 0 to 30 degrees.
For detailed information, see Optional Equipment on page 4 and refer to
Install Antenna Integrated Radio Units.

Installation Requirements
This section describes the installation requirements for installing the AIR unit.
For a complete installation description, refer to Install Antenna Integrated
Radio Units.
The AIR unit is only for outdoor installation. Pole installations can be either on
a pole, or on a mast or a tower).
The AIR unit is installed with the cable connections facing down. Allow a
minimum of 500 mm free space below the AIR unit to ensure sufficient working
space.
3.4.1
Outdoor Installation Environments to Avoid
The AIR unit is designed for outdoor use but to ensure optimal operation avoid
the following:
•
Hot microclimates caused, for example, by heat radiated or reflected from
dark or metallic walls or floors
•
Chimney mouths or ventilation system outlets
•
Large glass or concrete surfaces
Avoid radio interference by keeping the area directly in front of the antenna
clear of the following:
12
•
Metal surfaces or objects such as railings, ladders, or chains
•
Equipment generating electromagnetic fields, such as electric motors in air
conditioners or diesel generators
•
RBS equipment

3.4.2
Painting Limitations
Ericsson does not recommend painting the AIR, especially not the radome, as
it may affect radio performance of the unit.
Ericsson will apply limitations to the warranty and service contract if the AIR is
painted.
3.4.2.1
Technical Limitations
If the AIR is painted, be aware of the technical limitations below:
•
Sunlight on dark paint can increase the temperature of the AIR causing it
to shut down.
•
The plastic surfaces and the plastic covers are suited for painting with
normal commercially available one or two component paints.
•
Never use metallic paint or paint containing metallic particles on the
radome.
•
Ensure that ventilation and drainage holes are free from paint.
•
Ensure proper adhesion of the paint.

13
Antenna Integrated Radio Unit Description
3.4.2.2
Commercial Limitations
If the AIR is painted, the commercial limitations below apply:
3.5
•
Failure modes directly related to overheating due to painting are not valid
for repair within the scope of the warranty or standard service contract.
•
Product failures related to paint contamination of components of the unit
are not valid for repair within the scope of warranty or standard service
contract.
•
When a painted unit is repaired, it will be restored to the standard color
before being returned to the market. It is not possible to guarantee the
same unit being sent back to the same place. This is also valid for units
repaired under a service contract.
•
For repairs within the warranty period or a standard service contract, the
customer will be charged the additional costs for replacing all painted
parts of the unit or the complete unit.
Acoustic Noise
The AIR unit emits low levels of acoustic noise.
The sound pressure level under normal operation can be up to 36 dBA.

Power Supply Characteristics
This section describes the power supply requirements, power consumption,
and fuse and circuit breaker recommendations for the AIR unit.
3.7.1
DC Power Supply Characteristics
The power supply voltage for the AIR unit is −48 V DC.
67/1551-LZA 701 6001/1 Uen B | 2017-02-17
15
Antenna Integrated Radio Unit Description
The following is a list of the power supply requirements:
Nominal Voltage
−48 V DC
Operating Voltage Range
−38.0 through −58.5 V DC
Non-destructive Range
0 through −60 V DC
The AIR unit is designed for 2-wire power connections.
Fuse and Circuit Breaker Recommendations
The recommended fuse rating is 20 A for single band active, and 2 x 20 A for
dual band active.
The maximum cross-sectional area of the power cable conductors supported
by the power cable connector is 10 mm2.
The recommendations given in this section are based on peak power
consumption, and they give no information on power consumption during
normal operation.
The recommended melting fuse type is am-gL-gG, according to IEC 60269-1.
Circuit breakers must comply with at least Curve 3 tripping characteristics,
according to IEC 609 34.
The AIR unit has a built-in Class 1 (Type 1) Surge Protection Device (SPD) to
protect the equipment in case of lightning and network transients. The
recommended fuse or circuit breaker rating is therefore dimensioned to not trip
the fuse or circuit breaker in case of most SPD operation.

Interfaces
This section describes characteristics of each interface on the AIR Unit and
Radio Unit.
5.3.1
Position A, Grounding Interface
The AIR unit must be grounded to protect it from overvoltage and lightning
strikes. The grounding interface on the AIR unit accepts an M6 dual cable lug
on a coated cable as shown in Figure 18.

Connection Interfaces
5.3.4
Position H, M and R, −48 V DC Power Supply Interface
The -48 V DC power connection is made through a connector with a 2-wire
connection. The connector accepts cables with various cross-sectional areas
depending on the cable length and the AIR unit consumption. The values can
be found in Figure 19, and are calculated using the following formulas:
R=2*(0,02/A)
R = cable resistance per meter
A = cable area (mm2)
L=4V/(R*i)
L = the maximum permitted distribution length
R = calculated cable resistance
V = volt
i = current that the AIR active part radio unit uses at 38 V DC
Figure 19 Maximum Cable Lengths and Air Active Part Radio Unit Power
Consumption (4V@38V)
The power cable conductor has a wire for both the 0 V conductor and a wire
for the -48 V DC conductor. The colors of the wires are market-dependent.
All cables must be shielded. The shielding must be properly connected both to
the power connector and to the grounding in the power supply equipment;

otherwise, the AIR unit over voltage and lightning protection does not function
properly.
5.3.5
Position S and T, Interface for Optical Cable to Radio Unit
The
1 and
2 interfaces provide connections to optical cables for traffic
and timing signals between the AIR and external unit. An Small Form-factor
Plugable (SFP) is used to connect the optical cable to the AIR.
Note:
The AIR uses SFP modules for optical transmission and optical radio
interfaces on Data 1 and Data 2.
Only use SFP modules approved and supplied by Ericsson. These modules
fulfill the following:
•
Compliance with Class 1 laser product safety requirements defined in
standard IEC 60825-1.
•
Certification according to general safety requirements defined in standard
IEC 60950-1.
•
Functional and performance verified to comply with RBS specifications.
Recommended SFP modules are obtained from the product packages for the
RBS and the Main Remote Installation products. See Spare Parts Catalog and
Main-Remote Installation Products Overview for more information.
