Mesh Deployment Solutions

  • You can configure the following single-hop and multi-hop solutions:
  • Thin AP services with wireless backhaul deployment
  • Point-to-point deployment
  • Point-to-multipoint deployment
  • High-availability deployment

With a thin AP wireless backhaul deployment, mesh provides services and security to remote wireless clients and sends all control and user traffic to the Mobility Master over a wireless backhaul mesh link.

The remaining deployments allow you to extend your existing wired network by providing a wireless bridge to connect Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments. You can use these deployments to bridge Ethernet Ethernet is a network protocol for data transmission over LAN. LANs between floors, office buildings, campuses, factories, warehouses, and other environments where you do not have access to physical ports, or cable to extend the wired network. In these scenarios, a wireless backhaul carries traffic between the Aruba APs configured as the mesh portal and the mesh point, to the Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server..

The following topics provide information on the single-hop and multi-hop mesh deployment solutions:

Thin AP Services with Wireless Backhaul Deployment

To expand your wireless coverage without bridging Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments, you can use thin AP services with a wireless backhaul. In this scenario, the mesh point provides network access for wireless clients and establishes a mesh path to the mesh portal, which uses its wired interface to connect to the managed device. Use the 802.11g 802.11g offers transmission over relatively short distances at up to 54 Mbps, compared with the 11 Mbps theoretical maximum of 802.11b standard. 802.11g employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speed of 11 Mbps, so that 802.11b and 802.11g devices can be compatible within a single network. radio for WLAN Wireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. and managed device services and the 802.11a 802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps. radio for mesh services. Figure 1 shows the wireless backhaul between the mesh portal to the mesh point that services the wireless clients.

Point-to-Point Deployment

In this point-to-point scenario, two Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments are bridged through a wireless connection that carries both client services traffic and mesh-backhaul traffic between the mesh portal and the mesh point. This provides communication from one LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. to another. Figure 2 shows a single-hop point-to-point deployment.

Point-to-Multipoint Deployment

In a point-to-multipoint scenario, multiple Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments are bridged through multiple wireless or mesh backhauls that carry traffic between the mesh portal and the mesh points. This provides communication from the local LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. to multiple remote LANs. Figure 3 shows a single-hop point-to-multipoint deployment.

High-Availability Deployment

In this high-availability scenario, multiple Ethernet Ethernet is a network protocol for data transmission over LAN. LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. segments are bridged through multiple wireless backhauls that carry traffic between the mesh portal and the mesh points. You configure one mesh portal for each remote LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. that you are bridging with the host LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server.. This provides communication from the host LAN Local Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server. to multiple remote LANs. In the event of a link failure between a mesh point and its mesh portal, the affected mesh point could create a link to the other mesh portal. Figure 4 shows a sample single-hop high-availability deployment. The dashed lines represent the current mesh link between the mesh points and their mesh portals. The diagonal dotted lines represent possible links that could be formed in the event of a mesh link or mesh portal failure.
