Abstract
As the Internet of Everything (IoE) becomes a reality, IEEE af strives to create a wireless world that enables Spectrum for Everything (SfE). This presentation will describe some of the unique advantages of af technology, and how it opens up huge opportunities for networks working in license-exempt spectrum.

4. IEEE 802.11af Radio Technology
July 2013
IEEE af Radio Technology
IEEE ac is designed to operate in the 5 GHz bands
Tremendous capacity gains
Up to 160 MHz channels for over 1 Gbps throughput
Able to operate in multiple, non-contiguous channels
IEEE af uses the same leading-edge technology, and scales it down for smaller channels
Can operate in 6, 7 or 8 MHz channels or multiples of them to match the TV band allocations
At least 5x times range advantage over 11ac, maximizing data throughput over longer range micro-cells

6. Band plan with new spectrum Importance of Additional Spectrum
Wide bandwidth channels desired to support high throughput requirements
At the same time, large number non-overlapping channels desired to support high QoS requirements
To avoid co-channel interference
Current UNII spectrum allows only
Six 80 MHz channels
Two 160 MHz channels
Additional unlicensed use of GHz and GHz would allow
Nine 80 MHz channels
Four 160 MHz channels

8. Geo-location Databases
July 2013
Geo-location Databases
Designed to maximize the use of under-utilized spectrum
For Experimental Licensed (like the US databases, where 24-hours is the standard of enablement)
For localized control (campuses, large enterprises, etc.)
A Registered Location Secure Server can maintain the area knowledge and be the enabler for one or more small networks

The RLSS
The RLSS provides the database function for multiple networks
It can access a regulatory database, or using centrally mounted antennas, provide available channel information based on sensing of the spectrum

10. Regulatory Flexibility
July 2013
Regulatory Flexibility
Regulatory limits are set in Operating Classes
Originally designed with the FCC in mind (because it had the only published rules at the time), the elements for operating in various regulatory domains gets coded into the Operating Classes
As more regulatory domains specify their rules, it require only the specification of the appropriate classes, or creating new classes

NOTE—Channel starting frequency is the frequency that results in the regulatory domain's channel number being the RLAN channel number.

Some Future Examples
In other bands, this technology can be used to provide interference-free spectrum access for special applications
For geo-survey satellite bands, it can secure the spectrum while a satellite is scanning a region, and share it when it is not, based on the highly predictable satellite path
For defense use of spectrum, eliminates the need to provide sensing data (like DFS) to maintain security of the satellite, UAV, etc.
