• If you’ve designed a network for dense 5 GHz coverage, then you have too many 2.4 GHz radios

• 5 GHz has 8x the channels of 2.4 GHz spectrum in the US.

• 2.4 GHz propagates roughly 1.5x farther

• With properly designed 5 Ghz coverage, 2.4 GHz becomes it’s own interference and causes more issues than it solves

• Prior to the 2800/3800 and 8.2 MR’s release, your only option was to disable up to 60% of these interfering 2.4 GHz radios.

• Disabling the radio provides no value from the hardware -no location, rogue or other information is gathered.

• RRM-FRA algorithm to identify redundant radios, and assign one of multiple roles that add value to the network.

• All Auto FRA, Client Serving 2.4 GHz

• AP’s #1, 2, 4 and 5 are all in the same room – at 2.4 GHz one will re-use an already used channel

• That’s 4 radios, but still just 3 channels available

• Coverage Overlap is the percentage (%) of a given cell that is covered by other AP’s at -67 dBm or greater

• All existing AP models considered in the coverage calculation

• The loudest 4 neighbors will be considered for coverage

• Only 2800/3800 can be marked as Redundant and assigned by FRA

• Using reciprocal NDP messages, each AP is given an x and y coordinate, we locate them relative to one another in RF Distance.

• Coverage area is represented by a circle around each AP – the diameter is based on present power level

• Overlap will be assessed based on a multi- point analysis within each AP’s calculated coverage area

• The resulting Overlap will be assessed based on multiple points within each target AP’s coverage area

• The loudest 4 neighboring AP’s will be used for coverage assessment

• COF - Coverage Overlap Factor – is the percentage of an AP’s cell – that is covered by neighboring AP’s

• A radio is only marked Redundant (and Re - assignable) if COF is above FRA Threshold (Low- 100%, Med – 95%, High – 90%)

AP2800/3800 “I” series antenna system (cover removed) Previously in the controller Access

Point radios were defined as…

Radio 0 = 2.4 GHzRadio 1 = 5.0 GHz

Using “Flexible Radio Assignment”Radio “0” can be configured as 2.4 GHz (default) or as an additional 5 GHz radio.

If configured as a 5 GHz radio the 2.4 GHz radio is disabled and the 5 GHz micro-cell antennas are used.

Micro-cell antenna is 6 dBi @ 5 GHzMacro-cell antenna is 5 dBi @ 5 GHz


Difference in antenna designs allow for RF co-existence

Conventional AP footprint (Macro-Cell) uniform 360Degree coverage

Smaller AP footprint (Micro-Cell) uniform 360Degree but for smaller coverage area (high density) deployments

By using spatially-efficient and compact antenna design along with different channels & Tx RF power –BOTH radios can co-exist internally


2800i/3800i Dual Band

Channel Utilization = 60%• The further a client is from the AP,

the lower the data rate will be• Data Rate is a function of SNR• The higher the SNR – The higher

the data Rate will be• 1 x5 GHz cell has a finite amount

of Air Time available• Capacity is the sum of all clients

• Creating two RF diverse 5 GHz cells – Doubles the Air Time available

• Optimizing Connections (Macro vs Micro) keeps like performing clients together, rather than have one drag down the other

• RRM will optimize, based on received RSSI only at FCS – Other possibilities exist (protocol, SS Capability)

• The most likely scenario is a client will associate to the Macro cell first – since it has higher power and bigger footprint

• In this case, a client that has RSSI at the AP above the Macro to Micro transition threshold of -55 dBm will be moved into the Micro cell• -55 dBm default, configurable by user

• For an 802.11v client – on association we will send an 11v BSS Transition request with the Micro Cell BSSID as the only candidate

• For a non 11V client, we will send an 11K neighbor list and a disassociate


Intra-cell Roaming – Macro to Micro

• If a client associates to the Micro cell first –less likely – but possible based on device scan and channels heard -

• In this case, a client that has RSSI at the AP at or below the Micro to Macro transition threshold of -65 dBm will be moved into the Macro cell• -65 dBm default, configurable by user

• For an 802.11v client – on association, we will send an 11v BSS Transition request with the Macro Cell BSSID as the only candidate

But Wait – There’s more!XOR radio as a WSM?

5GHzServing

WirelessSecurityModule

• Just like the WSM and WSM2, the XOR radio can be used to monitor all channels continuously (2.4 and 5 GHz serially)

• Since it does not serve traffic – dwell time can be exclusively dedicated to monitoring. That’s 1200 ms dwells vs 50 ms dwells

• On the slot 0 radio on the 2800/3800 the radio can also transmit – so it could behave as a client – Wireless Assurance anyone?

• At FCS – • Wireless Security Module functionality

• 160 MHz CleanAir• wIPS• Rogue Detection• RRM metrics
