Technical background

Co-Channel Interference Edge Users Roaming Bandwidth Limitation Of Cell Based System

 Radio channels are a scarce resource – use them wisely  Make each channel’s bandwidth available everywhere Bandwidth Limitation Of Cell Based System

Interference-Free™ Architecture  The channel blanket is formed from the aggregate coverage of all the APs  APs operate on the same channel(s) to create the channel blanket  The Switch completely controls the APs, preventing co-channel interference  The AP is only a radio/antenna; no software, no configuration; no IP address, no processing  The Client associates with the switch, not the AP; the APs are simply conduits between the client and the switch

Uplink in the Channel Blanket  Uplink path diversity  Multiple APs “hear” the client  Switch receives multiple copies of the same transmission, and selects the best one – making the uplink resilient to disruption on any one individual link  Seamless zero-latency mobility  As the client moves, different APs receive the uplink transmission - this is transparent to the client and no handoff event ever occurs  Elimination of client balancing problem that exists in cell-based WLAN (1) (2)

Netronics Wireless LAN  Total Mobility  Robust In Any Environment  Multi-Service Convergence  True Dual-Band n  Slashes the Complexity of Wireless and Networking

A Different Picture for Radically Different Results NetGlide Cell / Virtual Cell Based  Channel Blanket  No Cell Planning Complexity  Robust Connection  Zero-Latency Mobility  Client Consistency  Layer Any Mix of Channels, Modes and Band, from the Same Set of APs  Stacked Capacity  Built-In QoS  Dedicated Security “Simply a Better Way to Wireless”  Dramatic reduction in networking complexity

The NetGlide Experience  Guaranteed Performance  Move from “Best-Efforts” WLAN to Guaranteed Performance metrics  Surprising Simplicity  Take away the complexity of RF  Total Mobility  Voice demands true mobility – without it, convergence cannot succeed  Voice, Data, & Video Without Trade-Offs  One infrastructure investment, many uses, serving different users with predictable quality of service

802.11n 2.4 GHz Scenario  Today’s 3 non-overlapping channels collapse down to 1 x 40MHz and 1 x 20MHz channel  “Full-performance” ‘n’ (i.e. the 300Mbps promise) requires a 40MHz- wide channel, with only ‘n’ clients  Mixing ‘g’ clients with ‘n’ on the same channel reduces throughput by 4X!  20MHz wide channels provide half the data rate as 40MHz channels Ch 1Ch 6Ch 11 MHz Today n/g 40MHz width 20MHz width

n b/g n/g ? ? ? ? ? ? Cell 1: 40MHz n/g cell Cell 2: 20MHz n/g cell Blanket 1: 40MHz “pure n” blanket Blanket 2: 20MHz legacy b/g blanket Mission Impossible: Not enough channels for cell planning Business as Usual: Enterprise- wide n + g/b WLAN Advantage Netronics in 2.4 GHz Band  Netronics is the only technology capable of supporting full-performance n clients and permanent co-existence with full- performance b/g clients, all in the same AP deployment.  Cell-planning is not viable – insufficient channels for channel planning.

Multiple WLANs in One means the only disruption-free, gradual introduction of full-performance ‘N’ in the enterprise Netronics n The Channel Blanket™ Comes of Age 2.4GHz ‘n’ 2.4GHz ‘b/g’ 5GHz ’n’ 5GHz ‘a’ or Rogue Monitor Data Voice Multimedia Locationing Any combination of channels, bands, modes, & security

Throughput Again and again, customers report how migration to NetGlide’s channel blanket solved their WLAN throughput problems.

“Our vision was basically to form a wireless backbone for anytime, any place learning, that doesn’t necessarily have to take place in the classroom.” Abdul Chohan, Essa IT Manager

The Challenge  Tablet PCs, iPhones, 50 wireless projectors, and an iPod Touch for every student to leverage podcasts and vodcasts as part of their day-to-day instruction.  Throughput, mobility, reliability must-haves

Checked Out The Competition First  “I was beginning to think that wireless LANs might not be a feasible solution, because co-channel interference can severely reduce basic network performance during high usage periods…

Then Discovered Netronics …Netronics seemed almost too good to be true. I hadn’t heard of Channel Blanket technology, and couldn’t imagine wireless without dead spots or limitations caused by interference. But we piloted the Netronics solution onsite, saw that the performance claims were real, and went forward immediately with it.” Abdul Chohan, Essa IT Manager

The Result…. Networked Wireless Laptops in-use

True Mobility, High Throughput Networked IPAD in-use

The Challenge  How do you control a floor of  fast-moving robots?  High RF Noise due to  metal building walls!  RF ‘canyons’ (the aisles)  Any WLAN outage will shut- down the system !!!

“Especially in the fault conditions we looked into, Netronics performed effortlessly compared to other technologies. “Seamless mobility is very important to us, and Netronics technology is what makes that possible.” Matt Verminski, Kiva Engineering Kiva Feedback
