MDS 05-6302A01, Rev. A MDS Mercury 16E Technical Manual 9
Setup for Maximum Throughput
To demonstrate maximum throughput, several configuration changes
must be made. In addition, the link needs to be cabled according to
Figure 6, with a strong signal, that is, above -70dBm. If necessary, the
link attenuation should be adjusted to reach the desired RSSI level. The
transmit power of the Base Station should be reduced to 10 dBm to
ensure that the Subscriber only receives the signal through the cables
and not directly from enclosure to enclosure.
With this strong signal the modulation rate downlink and uplink should
be 64QAM FEC 5/6. There may need to be data flow, such as an ICMP
ping, in order to have the modems shift up to this modulation rate. Both
the Base Station and Subscriber need to be set for MIMO Type Matrix
A/B. The Base Station should have HARQ (4) enabled and ARQ
disabled. These changes are made using the Configuration - Radio page.
This setup and configuration can be used with any RF bandwidth.
Approximate aggregate throughput for each bandwidth is given below.
3.0 FEATURE DESCRIPTIONS
3.1 Security Features
Overview
The Mercury transceiver employs many security features to keep the
device, network, and data secure. Some of these features include
WiMAX PKMv2, EAP-TLS, and AES-CCM encryption on the
WiMAX interface and HTTPS, SNMPv3, and RADIUS authentication
for the configuration interfaces.
Authentication
Authentication is the process by which one network entity verifies that
another entity is who or what it claims to be and has the right to join the
network and use its services. Authentication in wireless SCADA
networks has two primary forms: User Authentication and Device
