Wireless Mesh is a powerful means of extending a data network across long distances, even to moving vehicles within a radius. Think of it as a port in your network; if you add an office, you add a faceplate, thereby extending the network to that point. Mesh extends that network feed outside the building, for long distances.
Mesh nodes can transmit generally up to 11,000 feet with line of sight. You can string multiple nodes together for longer distances. See the attached case study from Thailand, where they exceed 300 miles.
Mesh systems are designed to provide network connectivity across the entire distance, be blanketing the entire area, or by creating hot spot coverage, whatever the application and local conditions dictate.
The first node is considered the Host; subsequent locations are considered Clients. The idea is to start with a Host location that is connected to the City or company network, and then broadcast out from there to the Client locations. Thus you are extending that one network connection point to the entire mesh infrastructure.
Mesh differs from WiFi in that it is not a wireless connection point per se; WiFi allows direct connection to the network; Mesh allows only connection to that node, which then enables authorized users to access information. WiFi can be hacked via the device; you would have to hack the core switch to get inside a Mesh subnet of a network. However, mesh features WiFi connectivity with added modules if a customer wants it. That means a WiFi point is set up to connect to its corresponding node.
With Mesh, you would not “see” it as a wireless network on your laptop or smartphone; it would not be detectable at that level. A WiFi point attached to the Mesh would be, but you would not be able to gain access. If someone did hack the WiFi point, they could still not get past the corresponding node. Again, they would have to hack your core switch to hack the mesh; it cannot be accessed from the node side.
Mesh also differs from “point-to-point” wireless “bridge” applications. A wireless bridge connects point A to B across a wireless link. It is similar to one leg of a mesh system, but does not function as part of a larger network structure; bridge points communicate in pairs, period.
Mesh communicates to available nodes across multiple frequencies, and one node can manage traffic in on one frequency and out on another; this enables designers to build a network that provides coverage in the area around the node, while also extending the signal to the next node in line. Each mesh point houses (6) antennas for that purpose.
The wireless mesh concept calls for creating a “net” of network connectivity to cover an area; the mesh nodes communicate with each other collectively, not in sequence, but across the shortest path. This means if a node goes down, its companions will seek out the next nearest node, and continue operating. The idea is to design in redundancy for that purpose. All you need is power at each point; and you can tap street lights, traffic lights and other sources on the emergency grid for that.
Once you create the mesh, you connect switches that then serve cameras. Thus a video stream from a camera at the Rec Center can be viewed with central software at City Hall, or from a police car or any other point in the system.
The application for a City is the same as for a School; provide a secure network for security, video and other communications over their entire geography. It also helps police and fire personnel access this information without accessing other information they don’t need. It is part of the same overall network but partitioned separately.
Thus, a police chief can equip squad cars with nodes that allow them to access live video streams, download information to their laptops, and more. They can also install vehicle cameras and even add wireless personal cameras, so that encounters with the public, criminals, whatever are streamed into the system with date/time stamps that are watermarked for evidentiary purposes.
In addition, a 911 dispatch officer can view live video while speaking to a caller, and while directing personnel to the scene. That same video stream can be viewed by the responders.
In addition, it is better quality, and in real time.
Another application we can provide is via RFID – using RFID tags on cars and buildings, we can trigger automatic uploads to a central server farm as an officer pulls up to the building. This upload stream can be sequenced in segments that allow for changes to occur without disrupting the record; for example, if the officer suddenly receives another call and races away, the upload stops at its last sequence point; when they return, it resumes at that same point; the central record is not affected. The officer also doesn’t have to do anything, remember anything, learn any steps to take, etc. The steps are programmed in and maintained for them.
Another point is that mesh allows other types of security; thus we can provide card access of a concession stand or ticket booth in the middle of a field, without running new wire. The Yuma Airport case study attached shows that application at a remote parking lot.
So these are just a few ways in which Mesh can enhance security, by enabling more and better use of existing devices.

It looks like the friends at Redmond will be hosting a special unveiling of next-gen Xbox. Current Xbox Live users can tune in via the soon-to-be-old-news XBOX360, everyone else can find it on Spike TV.
Now available for streamers and Cord-Cutters alike, the new Roku 3 launched a few weeks back and boasts a new interface, remote audio, and a more powerful CPU. For fans of Roku, you’ll find all of your favorite features, but with a new AppleTV-esque tiled layout to the menu system, making it easier to find your favorite channels. The upgraded CPU means better stability and extra horse-power for those of you running the Plex media server to pipe your own content to the device. For newbies, the Roku is the “other” streamer out there, that allows access to all of the major and many of the obscure video streaming services out there. New for the Roku 3, the remote now includes a headphone jack, so that you can plug in your favorite set of Bowers& Wilkins headphones to listen to your favorite shows without disturbing those around you. The Roku 3 can be had for $99, and includes HDMI and WiFi. Unlike the predecessors however, the Roku 3 does NOT offer any connections for analog TVs. For more info, call, email, tweet at us, or just stop on by.
A post today is adding fuel to the fire that the new Xbox will not only be a kick-(butt) gaming system, but will be even more part of your media universe. The new box is rumored to include enhanced media streaming building off the highly successful XBOX360, and a GoogleTV-like set of features, making the new XBOX your cable-box / media streamer / game system / web browser box. Check out the link, or call, email, tweet @AudioVideoInt, or stop by for more.
For those of you who have followed our “Cutting the Cord” blogs, there is a new service on the horizon to assist you technology vanguards. Aereo has been providing service to many New Yorkers for the last few months, and they’re taking their talents to Cleveland (and 21 other cities). The service facilitates the free OTA (over-the-air) broadcasts for those of you who don’t have, cant, or want to use a terrestrial antenna.

Walmart Entertainment launched its in-store disc-to-digital UltraViolet conversion early last year, and now it’s making the process a bit simpler by letting customers do it by themselves at home. Powered by the Vudu To Go app for Mac and Windows PCs that already lets viewers stream or download movies in up to 1080p, they can search for previously purchased movies from participating studios (DreamWorks Animation, Lionsgate, MGM Studios, Paramount Home Media Distribution, Sony Pictures Home Entertainment, Twentieth Century Fox Home Entertainment, Universal Studios Home Entertainment and Warner Bros. Home Entertainment) and then convert them: DVD to SD or Blu-ray to HD for $2, DVD to HD for $5. Like the beta feature recently launched by Best Buy’s CinemaNow, the app authorizes the copy and then you can watch it through any of the numerous Vudu / UltraViolet-ready devices and services merely by logging in.
One other new feature on the way is the ability for Vudu users on iOS to download copies to their devices for viewing offline. We first saw the feature on mobiles when its Android tablet app launched last month, and it will come to the Apple family of hardware in mid-February. One other note as Walmart attempts to expand its “Entertainment” brand is a Facebook app that will let its fans read and submit reviews and also vote on which movies will be offered for sale in-store and online. Still need a reason to give UltraViolet a try? Vudu is tossing new users 10 free pre-selected movies just for linking their account or signing up.

LG just gave a price to its entry level 55-inch OLED TV: $12,000. That’s the starting price, mind you. There are three different OLED sizes to choose from, but we’re only seeing 55- and 65-inchers — no word on pricing for the larger set, but we’d wager it’ll be a pretty penny over that initial $12K. You can put in an order now, and LG’s saying it’ll arrive in March. The South Korean electronics company also mentioned partnerships with Activision, Verizon, Google, and Disney for its OLED line, and teased a third size for launch in 2013. Presumably that largest size will require a second or third mortgage, but we’re hoping to hear more specifics during CES this week.
From the Press Release:
LG Electronics USA Announces Availability of Eagerly Anticipated OLED TV
March U.S. Rollout Will Follow Early Launch in Korea
LAS VEGAS, Jan. 7, 2013 /PRNewswire/ — LG Electronics USA announced today that the revolutionary new LG OLED (Organic Light Emitting Diode) TV will be available in the United States beginning in March.
The eagerly-awaited 55-inch class (54.6-inch diagonal) WRGB OLED TV went on sale for the first time in South Korea last week with deliveries scheduled to begin there in early February.
The suggested price in the United States is expected to be $11,999, LG Electronics USA said here today at the 2013 International CES®, where an earlier version of the TV previewed last year was awarded “Best of Show.”
As the first company to announce availability of the next-generation TV technology, LG is prepared to ramp up quickly to take the lead in the OLED segment that is expected to grow to 7.2 million units by 2016, according to DisplaySearch.
“OLED TV will usher in a whole new era of home entertainment,” said Jay Vandenbree , senior vice president, LG Electronics USA Inc. “With its lifelike color, infinite contrast ratio and slim profile, LG OLED delivers an outstanding viewing experience; it’s undoubtedly a premium product worthy of its premium price.”
Havis Kwon , global president of the LG Home Entertainment Company, said: “Not since color TV was first introduced 60 years ago has there been a more transformational moment. When high definition TV was first introduced 15 years ago, the public’s reaction was ‘wow!’ Now, when customers see our razor-thin OLED TV for the first time, they’re left speechless. That’s a clear indicator as any that OLED TV is much more than just an incremental improvement to current television technology.”
Only 0.16 inches (4 millimeters) thin and weighing less than 22 pounds (10 kilograms), LG’s OLED TVs produce astoundingly vivid and realistic pictures thanks to its superior WRGB technology:
LG’s unique Four-Color Pixel system features a white sub-pixel, which works in conjunction with the conventional red, blue, green setup to create the perfect color output.
LG’s exclusive Color Refiner delivers even greater tonal enhancement, resulting in images that are more vibrant and natural than anything seen before.
The 55-inch OLED TV also offers an infinite contrast ratio, which maintains optimal contrast levels regardless of ambient brightness or viewing angle.
Even before its official 2013 launch, the LG OLED TV has been turning heads all over the world. In addition to being named Best of Show at CES 2012, the influential Industrial Designers Society of America recognized the TV with a coveted IDEA Award. Meanwhile, LG received the European Display Achievement 2012-2013 Award from the European Imaging and Sound Association (EISA). LG’s OLED received Korea’s Good Design President Award in October.
