Chapter 3 - Operation and Administration
In MIMO Matrix A or B mode the system can use either MIMO Matrix A or MIMO Matrix B. The selection
between Matrix A and Matrix B is performed automatically for each MS according to link conditions and
supported MS capabilities.
MIMO Matrix A for Coverage Gain: In configuration with multiple transmit/receive antennas, a single
data stream is transmitted in parallel over multiple paths. A mathematical algorithm known as Space
Time Codes (STC) is used to encode the data streams to make them orthogonal to each other. This
improves the signal to noise ratio at the receiver side, resulting in increased range and better
throughput for subscribers that are difficult to reach (e.g. deep indoors).
MIMO Matrix B for Increased Capacity: This flavor of MIMO, also known as Spatial Multiplexing
MIMO (SM-MIMO), sends an independent data stream over each antenna. Thus, in case signal
conditions are good, the data rate is increased and in excellent conditions may be doubled.
3.7.2.3 Mobility
The Mobility menu enables viewing/updating the value configured for the following parameter:
3.7.2.3.1 Deployment
The type of deployment in the area served by the BS: Fix or Mobile. To support proper handover, should
be set to Fix only if mobile MSs are not expected. The default is Fix.
A change in the Deployment parameter will take effect after next reset.
3.7.2.4 Power Control
The Power Control menu enables viewing/updating the values configured for the following parameters:
Target Ni
Allowed Interference Level
3.7.2.4.1 Target Ni
The target noise and interference level for the PUSC zone, in dBm.
The range is from -130 to -110 in steps of 1 (dBm). The default is -127.
3.7.2.4.2 BS Transmit Power
Available only in Show menu. The Transmit Power of transmissions from the BS. Calculated according to
the TX Power configured for the Radio Cluster and the Topology Type. In the current release (supporting
only One Sector One Carrier topology) the BS Transmit Power is the same as the Radio Cluster's TX
Power.
3.7.2.4.3 Allowed Interference Level
This parameter defines the correction of maximum allowed UL SINR based on measured DL SINR.
The options are Very High, High, Medium, Low.
The default is High.
A change in Allowed Interference Level will take effect after next reset.
