Tsunami™ QB-8100 Series (50 Mbps / 12 Mbps)

Overview1.3 Multiple-Input-Multiple-Output (MIMO)Multiple-Input-Multiple-Output (MIMO) is a smart antenna technology that offers tremendous performance gains for wirelessdevices at relatively low cost. The underlying technology of the Tsunami QB-8100 product radios are based on acombination of MIMO and OFDM. High performance OFDM-MIMO radio combination enhances robustness using multipletransmitters and receivers, allowing the QB-8100 products to completely take advantage of this antenna technology. Inreal-world environments, signals reflect from various objects to reach the receiving antenna, hence a signal follows differentdistances before being received. This phenomenon is called Multipath Propagation and causes interference and fading innon-MIMO radios. On the receiver side, having multiple receivers increases the amount of received power and also reducesmultipath problems by combining the received signals for each frequency component separately. Hence, MIMO significantlyimproves the overall gain.Figure 1-2 2x2 MIMO1.4 Management and Monitoring CapabilitiesA network administrator can use the following management and monitoring interfaces to configure and manage theTsunami QB-8100 products:• Web (HTTP/HTTPS) Interface• Command Line Interface (CLI)• Simple Network Management Protocol (SNMP) v1/v2/v3• ProximVision ES (PVES) [v2.2 and above]1.4.1 Web InterfaceThe Web interface (HTTP) provides easy access to configuration settings and network statistics from any computer on thenetwork. You can access the Web interface over your network, over the Internet, or with an Ethernet cable connected directlyto your computer’s Ethernet port. See Logging in to the Web Interface for more information.1.4.2 Command Line InterfaceThe Command Line Interface (CLI) is a text-based configuration utility that supports a set of keyboard commands andparameters to configure and manage the QB-8100 devices. You can enter command statements composed of CLI commandsand their associated parameters. You can enter commands from the keyboard for real-time control or from scripts thatautomate configuration. Refer to the Tsunami QB-8100 Reference Manual for more information about the Command LineInterface.1.4.3 SNMP ManagementIn addition to the Web interface and the CLI, you also can use Simple Network Management Protocol (SNMP) to manage andconfigure the QB-8100 devices. Note that this requires an SNMP manager program (sometimes called MIB browser) or aTsunami QB-8100 Series (50 Mbps / 12 Mbps) Installation and Management Guide 11
