Management And Monitoring Capabilities - Proxim Tsunami MP-8100 Series Installation And Management Manual

The simplest spatially multiplexed MIMO system contains two transmit chains, two receive chains, and two data streams.
When expanding such 2x2 architecture, several factors need to be considered. For example, at the device operating frequency
of 2.4 GHz, the wavelength is 12 cm, the dimension of MP-8100 is ~35cm, hence a 2x2-receive-chain system has sufficient
antenna diversity to receive two uncorrelated signals. In a situation of not-so-perfect physical environment, a 3-receive-chain
system has a much higher probability of getting two uncorrelated signals in the same environment as a 2x2 system. Also,
when including the power consumption factor, 2x3 (2 transmit x 3 receive) combination MIMO works well for devices which
operate on lower power consumption budgets.
A 2x2 MIMO offers better antenna gain (3 to 6dB) over a similar form factor as a 3x3. A 2x2 improves range in good
conditions and is best suited for both Non-Line-of-Sight and Line-of-Sight. A 3x3 MIMO creates signal redundancy by
spreading the two data streams over three RF flows. Multiple data streams across multiple RF flows improve throughput
performance in difficult RF conditions and is ideal for Non-Line-of-Sight.
Theoretically, the performance of a MIMO system should improve with more transmitters and receivers. But it has been
observed that the increase in performance beyond the 3x3 configuration in not substantial enough to justify the circuit
complexity.

1.4 Management and Monitoring Capabilities

The network administrators can use the following management and monitoring interfaces to configure and manage the
Tsunami MP-8100 unit:
•
Web Interface
•
Command Line Interface
