•  ClientLink 3.0 focuses multiple transmit antennas in the direction of the client – better transmissions

•  ClientLink 3.0 optimizes network capacity by ensuring that 802.11a/n and 802.11ac clients operate at the best possible rates, especially when they are near cell boundaries – maximizes throughput

•  ClientLink 3.0 enables consistent 256 QAM with m9 rate on the 3700 – 1.3 Gbps speeds

•  ClientLink 3.0 improves battery life

Unmatched Speed to Deliver HDVX for VoWi-Fi in Dense Environments PERFORMANCE

•  802.11ac provides up to 1.3 Gbps

•  Advanced hardware architecture and an efficient packet scheduler is required to keep up with client counts of 60+ per radio

•  On-radio caching technology leverages additional RAM for per-client queuing techniques

Carrier Class AP Design


1.  Wi-Fi already carrying the bulk of smartphone data

2.  IEEE 802.11ac already delivering speeds in excess of LTE-Advanced

3.  Carrier neutrality enables Wi-Fi to be supported by venue-centric value chains

4.  Wi-Fi Calling and iMessenge demonstrate how the most valuable cellular bytes can now be transported over Wi-Fi networks

5.  Native ePDG client enables conversational services to be seamlessly supported between Wi-Fi and cellular

6.  Carrier Wi-Fi networks have already leapfrogged LTE in terms of dimensioning – average per user sustained busy hour rates approaching 100 kbps in certain deployments

7.  Overly complex cellular architecture is no longer needed in a “good enough” world

Time for a new mission statement? Time for “Wi-Fi First”?


Voice over Wi-Fi Models and Value Creation

•  Leverage 100s MHz of free spectrum to enable all services to be delivered over Wi-Fi

•  Address in-door coverage and capacity without additional licensed radio build out

•  Become more relevant to subscribers by offering Wi-Fi calling on non-SIM devices

•  Increase customer engagement/analytics even when they are “off” the cellular network

VoWifi in the spotlight

Major Use cases/drivers •  Complement Indoor Macro Radio VoLTE Coverage for residential and enterprise

•  Voice on non-SIM device (like wifi iPad) •  Compete with OTT VoIP


•  Yet, this is not a new topic and there have been past deployments with experiences •  UMA for 2G services over WiFi •  WiFi enterprise services with different options

•  Dedicated voice over WiFi clients within mobile phones (e.g. Cisco with Nokia and Blackberry) •  Specific voice over WiFi phone (e.g. Cisco 7920)

•  Lessons learned at the time •  Lack of capable handsets was a major issue for UMA •  WiFi access layer needs enhancements for voice handling including mobility •  Requires continuity and compatibility of services between WiFi and macro networks

Comeback of Voice over Wi-Fi Is this something new?


•  Residential Wi-Fi •  Usually good quality and not congested

•  Community & Coffee shop Wi-Fi •  Open does not mean immediately available •  Congestion could become a concern

•  Enterprises •  802.11n and now ac providing high capacity network •  However, many enterprises do block IPSec to untrusted external peers •  Multiple AP’s make Wi-Fi mobility unpredictable •  Multiple VoWiFi calls could be impacted

Is VoWiFi equally applicable to all indoor deployments ? Infrastructure, Environment and Policies do matter

•  ePDG is part of the 3GPP LTE SAE defined in 3GPP TS 23.402

•  ePDG is responsible for interworking between the EPC and un-trusted non-3GPP networks, such as WiFi access networks.

•  ePDG terminates IPSec tunnels established/initiated by UEs via un-trusted WiFi network for secure access to the EPC.

Internet VoWi-Fi Network Architecture

•  VoWifi Architecture requires: •  ePDG •  3GPP AAA •  PGW with s2b support •  PCRF •  IMS Core infrastructure •  TAS •  VoWifi capable UEs •  HSS

•  VoWifi capable UE pre-loaded with operator profile

•  UE discovers the ePDG using DNS lookup for ePDG FQDN – Statically or dynamically configured in Operator File

•  UE establishes IPSEC tunnel to ePDG

•  ePDG sets up a PDN session to PGW on behalf of UE

•  PGW allocates IP address and manages P-CSCF discovery – provides P-CSCF details to UE

•  UE SIP registers with SBC/PCSCF

•  UE makes/receives call via IMS/TAS •  P-CSCF discovery over IKE or operator profile
