The packet radio has the following interfaces:
•One interface for Power over Ethernet (1GE)
• One RJ45 interface for local management
The hardware is described in Section 6 on page 33.
Some functions described in this document are subject to license handling, that
is, a soft key is required to enable a specific function.

Figure 2 Network Scenario Overview
Using the MINI-LINK product portfolio to build an Ethernet network means that
there is a broad range of alternatives to choose from. There is support for
high-capacity Ethernet transport with different bandwidth and capacity options
over both radio and fixed connections.
The products offer the size and capacity to meet the needs of both last mile
access and first aggregation point, in a mobile backhaul network.

Radio Link Functions
3 Radio Link Functions
The packet radio operates within the 59–62 GHz frequency range, using 4, 16,
32, 64, 128, or 256 QAM, also supporting Adaptive Coding and Modulation
(ACM).
3.1 Adaptive Coding and Modulation
Adaptive Coding and Modulation (ACM) enables automatic hitless switching
between different ACM profiles, depending on radio channel conditions. Hitless
ACM makes it possible to increase the available capacity over the same
frequency channel during periods of normal propagation conditions.
Code rate and modulation (and thereby capacity) are high during normal radio
channel conditions and lower during less favorable channel conditions, for
example, when affected by rain or snow. ACM profile switches are hitless, that
is, error free. In situations where traffic interruption normally would occur, it is
possible to maintain parts of the traffic by switching to a lower ACM profile,
using hitless ACM.
Figure 3 shows how the capacity changes when the received input signal
crosses the receiver threshold for each ACM profile.

Technical Description
Figure 3 Principles of Adaptive Coding and Modulation
When using only Adaptive Modulation, the steps in Figure 3 only differ in
terms of modulation. When using ACM, the steps can differ in both coding and
modulation, which increases the number of possible steps.
In order to handle channel variations, the channel conditions are continuously
monitored on the Rx side by measurement of Signal to Noise and Interference
Ratio (SNIR). When the receiver, based on this data, detects that channel
conditions imply a change to the next higher or lower ACM profile, a message
is sent to the transmitter on the other side requesting a higher or lower ACM
profile. Upon receipt of such request the transmitter starts transmitting with the
new ACM profile. Each direction is independent. At demodulation the receiver
follows the ACM profile as a slave.
The ACM profile can also be configured with the maximum ACM profile equal to
the minimum ACM profile, and thereby achieving a mode comparable to static
mode, where the ACM profile remains unchanged.
Hitless ACM is compatible with Automatic Transmit Power Control (ATPC),
which is working in a closed loop only in the highest configured ACM profile. In
lower ACM profiles the output power is set as high as possible.
Note: Hitless ACM requires a license.
