WLANmall has partnered with Firetide the leader in linear mesh wireless technology to round out our portfolio and allow our customers greater flexibility when building their IP security networks. Here is how it works. Both radios in the mesh node are dedicated to backhaul communication. This in essence creates full duplex communication in the mesh which almost eliminates the loss per hop allowing the wireless mesh to span very large areas with out throughout injection points throughout the network. This lowers costs and simplifies installation.
MIMO Wireless Mesh Nodes (up to 600 Mbps):
Standard Wirless Mesh Nodes (up to 54 Mbps):
- 6201 Single Radio Outdoor mesh node
- 6202 Dual Radio Outdoor mesh node
- 6102 Dual Radio Outdoor mesh node
Wireless Mesh Nodes with 900 MHz Radios:
- 6200-900 Outdoor mesh node with One Tri-band radio, One 900 MHz Radio
- 6100-900 Indoor mesh node with One Tri-band radio, One 900 MHz Radio
In Q4 of 2009 Motorola announced the release of the AP-7181 dual radio, dual band, 802.11n wireless mesh access point. This AP is built specifically with video surveillance in mind as it bumps up the effective throughput dramatically. Using a datarate of 300Mbps and true 3×3 mimo you can expect the AP-7181 to achieve 100 to 125 Mbps of throughput (guessimate) between nodes. This is 5x more than their previous generation mesh AP the MotoMesh Duo. Along with speed Motorola added some other very cool features that also extend the range of the mesh AP dramatically.
Motorola’s exclusive intelligent ADEPT (ADvanced Element Panel Technology) antenna system was developed specifically for the AP 7181. The ADEPT system allows the AP 7181 to achieve maximum data rates by enabling dual data stream communication via integrated dual polarization antennas. Leveraging multiple transmit and receive RF chains, dual polarized antennas and software configurable down tilt, the AP 7181 achieves excellent coverage without the self-shadowing caused by multiple dipole antennas. This is great news for operators of mesh networks because better range mean fewer APs and more importantly fewer hops between them. Less hops means the less you must rely on backhaul networks to inject throughput back into the mesh.
Management of the entire Motorola Wireless Broadband portfolio including the AP-7181 happens via the one point wireless management suite. Some features of the one point wireless suite are:
- Device discovery
- Inventory management
- Alarm/event management
- Google Maps network view
- Over-the-air upgrades
- Fault, Configuration, Administration, Performance and Security (FCAPS)
The AP-7181 is available for order today for pre order and units should be shipping in March.
Wireless Mesh seems to still be misunderstood so I though I would put down a couple of pointers explaining how it works at a high level and focusing on throughput of course, we are talking about video here… Wireless mesh networks require a good amount of planning and unfortunately are not as easy to deploy properly as most vendors would like you to think, but can be useful for specific applications.
A wireless mesh network normally spans a large area of land and therefore requires a distributed architecture in order to make it work. The diagram above attempts to break down the typical components of a wireless mesh network. You may notice that I used Motorola Canopy Visio stencils to make this diagram but I only did that because those were the only stencils I had and Moto has a nice representation on their website that helped me put this together. I am not endorsing a specific manufacturer in this blog and recommend that you look through the many manufacturers and find the one that is right for your application.

Ruckus Wireless has released a full blown mesh technology for their ZoneFlex series of access points and controllers. Ruckus‘ “SMART Mesh” technology is controlled by the Zone director and with this new upgrade you can now manage all ZoneFlex APs whether wired in to the network or connected wireless via mesh. This is a HUGE improvement over the Ruckus Light Mesh Gateway which would simply act as a repeater and not acquire BSSID, security, user information, etc. The new SMART Mesh technology simplifies the installation of the ZoneFlex WLAN even further! Ruckus SMART Mesh is only available for clients with a Premium contract which will give you access to the new 6.0 firmware.
Here is some nice marketing info for you guys…
Ruckus Wireless SmartMesh is a unique, new approach to building high-performance wireless LANs (WLANs). It reduces cumbersome RF planning and costly cable backhaul by lowering the need to run Ethernet wiring to individual ZoneFlex Smart Wi-Fi access points.
SmartMesh dramatically simplifies, speeds and reduces the cost of WLAN deployment. With SmartMesh, enterprises now simply plug ZoneFlex access points into any convenient power source, and walk away. No extensive RF site surveys, cable runs, configuration, or optimization adjustments are required.
SmartMesh delivers three key ingredients that have previously hindered the use of indoor meshing:
- high performance by combining 802.11n with Smart Wi-Fi technology
- reliable connectivity between mesh nodes, using best path selection and interference avoidance techniques
- ultra-simple deployment through the automation of AP and mesh provisioning
SmartMesh extends Ruckus-patented Smart Wi- Fi technology to create a new class of reliable and high-performance wireless LANs that are selforganizing, self-optimizing and self-healing. It is the first Wi-Fi meshing approach that combines high-gain smart antenna arrays, sophisticated RF routing and centralized management with a single WLAN system.

Calabasas-based wireless mesh networking hardware provider Strix Systems has signed a deal to provide its hardware for a use in the 2008 Olympics in Beijing, the firm said earlier this week. Financial impact of the win was not announced, but Strix said that its outdoor wireless networking system has been integrated into emergency response vehicles and other personal mobile communications for public safety. Strix said the win was a part of a design by Silicon-Star Science & Technology Development Co. Ltd and Beijing Aerospace Changfeng Co., Ltd, which will be used in the Olympic Stadium and downtown Beijing during the Olympic Games.
