RF Intelligence Helps Service Providers
Deliver High-Quality Service over Wi-Fi
ClientLink
BandSelect
Beamforming: focusing RF energy
towards clients
AP-assisted 5Ghz band selection
• Up to 87% throughput improvement
• 20% range increase
• Optimizes RF utilization
• Frees up 2.4GHz space for single band
clients
• Tested & validated by
• Higher user density
CleanAir
Silicon-based spectrum analyzer
• Automatically mitigate impact of
wireless interference
• Self-healing, optimization
• Network-wide visibility
What is Clientlink Technology?
 Silicon-level intelligence that focuses DL RF energy
(Beamforming) directly to 802.11a/g clients
 Higher Signal Strength ► Higher Throughput (up to 85%)
 Higher Signal Strength ► More Range (~20%)

What is CleanAir Technology?
 Silicon-level intelligence to automatically mitigate the impact of
wireless interference, optimize network performance and reduce
troubleshooting costs
 Classification processed on Access Point
 Interference impact and data sent to WLC for real-time action
 WCS and MSE store data for location, history, and troubleshooting

Inter-Access Mobility Requirements
Overview
• Multiple Interface on UE and Connection Management
-
Requires Network functions like HS20 and ANDSF
Requires Device functions like Connection Manager
• Fast Roaming
- To be further investigated in standards for Residential (Fast Re-authentication with Key
sharing)
• IP session persistency
-
Requires DSMIPv6 or MIPv4 client in client based approach
For Network Localized Mobility
-
It requires a Virtual IP intf. on the UE which hides the Mutiple Intf. to the applications
It requires a Common IP Anchor for the Session like a PGW
For 3G – WiFi, it requires S4 SGSN model and LTE capable devices
• IP Flow Mobility
-
Traffic Class to segregate Flows on different interface (upstream) and networks
(downstream)

3. Go to Webauth
4. Browse webpage and enter right
credential, usually ID/PWD
5. Choose roaming plan

Dynamic selection of PGW
3GPP to Wi-Fi
•
HSS knows which PGW is the UE PDN anchored.
This was provided by SGSN/MME
•
Upon ACCESS AUTHO REQ from the WAG, the
AAA provides the allocated PGW with the
corresponding PDN info to the WAG, after querying
the HSS that provides that information as part of
the UE Subscriber data, providing also the MN-NAI
to use in the PBU
•
PGW updates AAA using AUTHO REQ and the
AAA does the same with the HSS
•
HSS knows which PGW is the UE PDN anchored.
This was provided by PGW.
•
During the Attach Procedure, the MME will perform
a LU and SDR where the UE PDN Subscription
information is provided.
•
UE dependencies as this has to set Handover
