7.7 billion new Wi-Fi (a/b/g/n) enabled devices will enter the
market in the next five years.*
By 2015 there will be 7.4 billion 802.11n*
1.2 billion Smartphones will enter the market over the next
five years, about 40% of all handset shipments.*
Smartphone adoption growing 50%+ annually.**
Currently 16% of mobile data is diverted to Wi-Fi, by 2015
this will number will increase to 48%.*
By 2012, more than 50% of network devices will ship
without a wired port.***

What are RRM’s objectives?
To dynamically balance the infrastructure and mitigate
changes
Monitor and maintain coverage for all clients
Manage Spectrum Efficiency so as to provide the optimal
throughput under changing conditions
• DCA—Dynamic Channel Assignment
Each AP radio gets a transmit
channel assigned to it
• TPC—Transmit Power Control
Tx Power assignment based on
radio to radio pathloss
TPC is in charge of reducing Tx on some APs—but may also increase
Tx by defaulting back to power level higher than the current Tx level
• CHDM—Coverage Hole Detection and Mitigation
Detecting clients in coverage holes

Understanding Multipath and Beam-Forming
Why you want more receivers and Client Link 2.0
802.11a/g/n
802.11n with multiple transceivers increases fidelity
creating a more predictable and reliable performance.
AP-3600 is dual band with 8
transceivers (4 per band)
that’s two additional radios
more then the competition
The AP-3600 supports three spatial streams with four transceivers
for even greater performance and then adds Client Link 2.0
Client Link 2.0 benefits 802.11a/g/n 1-SS, 2-SS and 3-SS clients

AP-3600 – Key takeaways
• The extra spatial stream with its additional MCS rates improve reliability
and performance allowing faster throughput and more data rates choices to
be able to shift to.
• Support for extra spatial stream as well as Client Link 2.0 an 802.11n
beam-forming method with the FOUR transceivers per band (one more
than everyone else) results in less retries and more predictable
performance. Net result, it increases the overall data rates @ usable
distances maintaining a better link at those top speeds
• New Macbook Pro and other devices are coming to market with three
spatial streams so the faster throughput with the additional spatial stream is
finally gaining meaningful traction in the enterprise.
Three spatial streams permit MCS16-23 for up to 450 Mbps throughput

• Stadium/Arena owners desire to provide WiFi coverage to fans in the seats
to enhance the game day experience, typically a challenge due to
• High potential users in confined space (high client density)
• Limited spectrum with high RF interference
• Directional high gain, dual band antennas create concentrated WLAN cells
within seating areas
•6-element Dual Band 2.4/5 GHz with 13/7 dBi gain, respectively
•Narrower propagation beamwidth for lower interference
•High uplink gain benefits lower client power requirements
•CleanAir to detect and mitigate RF interference
•Sets the way for Connected Stadium…

• 802.11u – Interworking with External Networks
• Purpose:
Interworking with External Networks is a key enabler to allow IEEE 802.11 devices
to interwork with external networks, as typically found in hotspots or other public
networks irrespective of whether the service is subscription based or free.
Interworking Service aids network discovery and selection, enabling information
transfer from external networks, and enabling emergency services. It provides
information to the STAs about the networks prior to association.
• Function:
Network discovery and selection (NDS)
Generic Advertisement Service (GAS)
Access Network Query Protocol (ANQP)
Interworking Element
Provide lightweight
support for network
selection
GAS provides support for other higher-layer network discovery, service advertisement and
mobility management protocols
• Status: IEEE 802.11u-2011 is a fully ratified IEEE standard

• Support the same use cases
• Data/video/voice
• With similar range
• 30-100+ ft range
• But faster, more in line with 1GigE
• E.g. can support multiple HD video streams at range
• And maintain these benefits even for smartphones/tablets
• With just one antenna

• Throw away your physical dock
• Automatic wireless discovery of peripherals
• Walk in and start work
• Wireless keyboard/mouse, likely via Bluetooth
• Wireless display, via a 11ad/DisplayPort adapter
connected to the display and later 11ad
integrated into the display
• Wireless hard drive via 11ad/PCIe adapter
• Wireless networking
• Oftentimes will be classic 11n/11ac Wi-Fi
• But could be an 11ad/Ethernet wallwart
adapter, or a triband AP

• Nástup mobilních zařízení, primární komunikační médium – WiFi a
3G/GPRS
• Požadavky na vyšší hustotu pokrytí, vyšší spolehlivost
• Požadavek na stejné chování drátové a bezdrátové sítě
=>
• Enterprise vlastnosti bezdrátových sítí => vyšší propustnost a
spolehlivost, video, schopnost řídit i větší bezdrátové sítě
• Konvergence drátové a bezdrátové sítě => stejné připojení všech
klientů, jednoduchá správa, dohled a řešení problémů
• HotSpot 2.0 => 3G offload, nové aplikace
• Nové standardy 802.11ac, 802.11ad, … => výrazné zvýšení propustnosti
bezdrátových sítí
