Ensure that antenna weep holes always face up
What is the main difference between the RFM link list and the RFM neighbor list?
RFM link list only shows the links that are currently up and running, while the neighbor list shows all the links.
RFM neighbor list is a subset of RFM link list.
RFM neighbor list shows all nearby mesh nodes that can be found by RFM through scanning, while the RFM link list only shows mesh nodes to which a link was formed recently.
The RFM link list cannot help with debugging downed mesh links.
Which of the following are functions of the Aruba MeshOS RFM module? Choose all that apply.
Prevent loops on the datapath
Ensure the convergence of mesh network topology
Calculate the forwarding path between two nodes for data traffic
Automate channel assignment for the backhaul links
The command used to specify the maximum number of backhaul links allowed for the given radio is?
Which modules work together closely to automatically form the mesh networks?
Which statements about the function of an antenna are true?
An antenna is a transducer that transmits or receives electromagnetic waves
Antenna does not affect the EIRP of the radio
An antenna is an electromagnetic generator, that adds power to a transmitted signal
A directional antenna is like a reflector of a flashlight that concentrates the radiated power into a specific area
Downtilt omnidirectional antennas are primarily useful for
Covering large open areas from low mounting locations (e.g. playing fields)
Covering environments with lots of vertical obstructions using high mounting locations (e.g. container yards)
Maximizing backhaul bandwidth on point-to-multipoint mesh deployments

WLAN device issuer Aruba Networks has unveiled the Aruba AirMesh out of doors instant systems portfolio. The Aruba AirMesh portfolio became designed to be deployed in a number of outdoor community situations, including beginning of facts, voice and HD video at oil and gasoline fields, mining operations, utility management and transportation amenities. native govt uses encompass municipal wireless deployments and public safeguard functions comparable to video surveillance, cell records transmission and disaster recovery.

SUNNYVALE, CA /company WIRE/ -- Aruba Networks Inc. unveiled the Aruba AirMesh outside wireless options portfolio. Designed to be the most scalable and high-efficiency out of doors mesh portfolio obtainable within the industry today, the Layer-three routing capabilities of all AirMesh products and the quad-radio architecture of the new flagship MSR4000 certainly differentiate it from other outdoor mesh solutions.
"Layer-3 routing capacity, which vastly improves scalability, can be increasingly essential for big-mesh networks of the class that serve municipalities and big outdoor industrial installations," observed Rohit Mehra, Director, business Communications Infrastructure, IDC. "clients should still additionally seem to be to the elimination of wired or overlay backhaul systems, enabled by using quad-radio architectures. This helps them cut the can charge of expensive cabling and eases both setting up and administration."
The Aruba AirMesh portfolio was designed from the ground up to be deployed in a large choice of outdoor network situations, including start of records, voice, and excessive-definition (HD) video at oil and fuel fields, mining operations, utility management, and transportation facilities. local government makes use of include municipal instant deployments and public defense purposes, akin to video surveillance, cell facts transmission, and catastrophe recuperation. Its clever multi-radio design, with dual- and quad-radio 802.11n MIMO structures, allows large skill, interference mitigation, and sustained throughput over assorted community hops.
on the port of Yokohama, Japan, site visitors from IP cameras, climate sensors, Z-Wave, and other Wi-Fi-enabled instruments is transferred with the aid of Aruba's AirMesh community to the iPhones and iPads used with the aid of workers and protection on the port. United conversation services Inc. (Unicom), which focuses on wireless and mobile know-how, acted because the system integrator for the project.
"proposing network connectivity in out of doors environments is commonly difficult because of the cost and disruption of running fiber to each and every location," mentioned Nobuharu Suzuki, corporate Officer and widespread AWMP supervisor of the Engineering department for Unicom. "Most instant mesh networks deployed today quite simply cannot scale to cowl gigantic areas and supply multi-service capabilities as a result of a legacy Layer-2 mesh switching architecture. With its Layer-3 routing architecture and quad-radio-enabled backhaul capabilities, Aruba AirMesh enables us to satisfy all of our outdoor networking needs, in spite of the number of hops or the category of application being delivered."
The Aruba AirMesh portfolio of products aspects Aruba MeshOS, with Adaptive instant Routing, featuring RF-conscious, Layer-three community intelligence to optimize traffic move, cut back latency, and ensure resiliency. lively Video Transport (AVT) optimizes and prioritizes video traffic, greatly enhancing video excellent via decreasing packet loss and jitter. AVT can identify video frames at 30 fps, a important means in start of HD video over multiple hops. Aruba's MobileMatrix technology allows for authentic roaming between mesh routers in under 50 ms.
"The clarity of the HD-best video and reliability of the Aruba wireless mesh network allows for Seattle police to give protection to the public with out requiring a expensive wired infrastructure," stated Monty Moss, a detective with the Seattle Police department. "The particular gadget that we designed is also incredibly bendy. Cameras, instant mesh routers, and antennas can be moved and repositioned anywhere within the city to make certain public safeguard at particular pursuits."
The Aruba AirMesh household comprises ruggedized single, twin, and quad radio structures that deliver fiber-like ability—up to 300 Mbps per radio. each application-configurable radio can feature as a mesh backhaul hyperlink or access element that operates in varied frequencies for ultimate efficiency and sustained throughput over distinctive hops. additionally, long-latitude directional antennae facilitate information transmission at distances up to six miles.
The Aruba AirMesh portfolio contains right here items:
Aruba instant Mesh skilled Certification ProgramIT professionals licensed as Aruba wireless Mesh professionals (AWMPs) will be in a position to set up and manage Aruba AirMesh outdoor instant mesh networks. The fee-based mostly certification examination is run on behalf of Aruba Networks at Pearson VUE check facilities. contributors during this path can have completed the Aruba wireless Mesh Networking route. AWMP certification is valid for 3 years. Recertification requires passing the then-existing version of the AWMP exam.
Aruba outdoor RF PlannerThe newly introduced Aruba 3D outdoor coverage Planning tool offers Aruba purchasers and companions an effective way to plan and visualize their Aruba AirMesh deployments in 3D, with precise predictions for sign electricity at each ends of link, in addition to upstream and downstream throughput and channel-specific displays. convenient-to-study AWMP, multi-coloured graphs generated by means of the planning tool certainly show client coverage, client throughput, elevation profile, and other deployment attributes.
North American Distribution settlement with ScanSource SecurityAruba introduced an agreement with ScanSource safety, a number one international distributor of specialty technology products, for sales of the Aruba AirMesh portfolio. ScanSource distribution network is well placed to fulfill latest and future Aruba purchasers' outdoor networking needs. This agreement covers North the united states.
"The AirMesh multiservice 802.11n outside community portfolio helps ensure that clients have respectable coverage and excessive first-rate of journey with video, voice, and data applications, inspite of their place and even in extraordinarily harsh environments," said Greg Murphy, vice chairman of out of doors Mesh Networking for Aruba. "This not only helps reduce the excessive can charge of fiber cabling however also gives users insurance when and where they desire it, whilst that alterations over time."
