  • This is good. but I do not see a point why Femto need to converge with WIFI. giving the HS2.0 and S2a GTP support for wifi integration, isnt wifi along can address all the issue (capacity and coverage) ? why femto is needed ?

  2. 2. Telecom Industry Landscape (As of now…) OTT service Providers Smart devices & OTT services leveraging on Telco networks has changed industry dynamics Increased demand on operator infrastructure in a high bandwidth data network What is the role of Wi-Fi and femtocells in the present ecosystem? Are they conflicting or complementary? The Mobile Operator
  3. 3. Content Overview of femtocells and Wi-Fi 1 From the perspective of current Telco landscape Femtocells vs. Wi-Fi 2 Conflict or Complement? Prospects in emerging markets 3 Selecting the “right” technology Trending……. 4 Hotspot 2.0, Data off-loading, The connected home…….
  4. 4. Overview of femtocells Small cells (femto/pico/micro/metro) are low-power wireless access points that operate in licensed spectrum, are operator-managed and feature edge-based intelligence. They provide improved cellular coverage, capacity and applications for homes and enterprises as well as metropolitan and rural public spaces. Source: www.smallcellforum.org Demand for data Need for more base stations Increase the number of small cells Operator expenditure (intentions) on small cells (Research by small cell forum)
  5. 5. Overview of Wi-Fi Wi-Fi networks use radio technologies called 802.11 to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect electronic devices to each other, to the Internet, and to wired networks which use Ethernet technology. Wi-Fi networks operate in the 2.4 and 5 GHz radio bands, with some products that contain both bands (dual band). Source: www.wi-fi.org Can the current capacity gap be met by cellular technologies alone? Spectrum & Capacity issues? Is there a cheaper alternative? Deployment of Wi-Fi Source: Agilent Technologies
  6. 6. Femtocells vs. Wi-Fi – A Technology Overview Femtocells Wi-Fi • 2.1 GHz – WCDMA/HSPA Frequency Band • 700MHz,800 MHz, 1.8 GHz,2.6 GHz….- LTE / • 2.4 GHz – IEEE 802.11 b/g/n LTE-Advanced • 5 GHz - IEEE 802.11 a/n/ac • 2.3 GHz – mobile WiMAX (WiBro) /LTE • 5 MHz, 10 MHz, 20 MHz • 3G – 5 MHz per carrier System Bandwidth • 40 MHz (IEEE 802.11n) • 4G – Up to 20 MHz per carrier • 80 MHz, 160 MHz (IEEE 802.11ac) • WCDMA – 384 kbps, HSDPA – 14.4 Mbps (DL) • LTE – 100 Mbps (DL, 2X2 MIMO) • Up to 450 Mbps (IEEE 802.11n) Data Rate • WiBro (802.16) – 50 Mbps (DL, 2X2 MIMO) • Up to 7 Gbps (IEEE 802.11ac) • LTE-A & WIMAX 802.16m – up to 1 Gbps Communication • 10 – 30 m • Up to 100 m Range

  8. 8. Femtocells vs. Wi-Fi Key Aspects Seamless Deployment Coverage Capacity Communication Aspects Spectrum Total Cost of Data Rates Handoff support Availability Ownership Quality of Indoor coverage Data Offloading Service Interference Device Support issues Network Planning
  9. 9. Femtocells vs. Wi-Fi – Coverage & Capacity Key Aspect Femtocells Wi-Fi • Licensed band. • Un licensed band. • Must re-use operator’s available spectrum • Operator need not concern with spectrum Spectrum Availability allocation. Therefore mainly used for coverage related issues as with femtocells extension (as well as capacity improvement) • Up to 10-30 m (transmit power of 1mW to 100 • Up to 100m (transmit power of up to 1W)Coverage mW). • Power levels of most Wi-Fi APs are higher Indoor Coverage • Power level will depend on the macro network than femtocells. to avoid/mitigate interference. • Co-channel interference with macrocell. • interference cancellation features in Wi-Fi • Interference avoidance and management (Cognitive Radio)(though interference from Interference Issues techniques (Self Organized Networks - SON) non Wi-Fi unlicensed band devices can be a will be necessary . problem) • Operator effort is needed for careful frequency • No special effort needed on network Network Planning planning and interference avoidance, which is planning also complicated by mobility of femtocells • WCDMA – 384 kbps, HSDPA – 14.4 Mbps (DL) • Up to 450 Mbps (IEEE 802.11n) • LTE – 100 Mbps (DL, 2X2 MIMO) • Up to 7 Gbps (IEEE 802.11ac) Data Rates • WiBro (802.16) – 50 Mbps (DL, 2X2 MIMO) • Possibility to provide LTE like data servicesCapacIty • LTE-A & WIMAX 802.16m – up to 1 Gbps in a 3G environment • Data offloading is inherently supported, • Data off loading is not inherently making it possible to uniform data plan supported. However 3GPP is currently throughout the network standardizing aspects such mobility Data Offloading management, policy control and charging seamless interworking with mobile networks
  10. 10. Femtocells vs. Wi-Fi – Other Considerations Key Aspect Femtocells Wi-Fi • Needs a user triggered mechanism. • Use the same technology as macro cells. Easy CommunIcatIon Handoff support for hierarchical handoff. Aspects of seamless mobility (PS) are currently being standardized Seamless • Operator may not have control over QoS Quality of Service • As the license band is managed by the unless the Wi-Fi network is managed by (QoS) operator QoS is carefully managed the operator • Device needs to have Wi-Fi (which most Device Support • No special considerations on the device smart phones do..) Deployment Aspects • There is a possibility of partnering with Total Cost of third parties for Wi-Fi access. Numerous • Deployed by the operator. And may be paid Ownership Wi-Fi deployments improve operator reach for by the consumer.
  11. 11. Femtocells vs. Wi-Fi – Summary Femtocells • Mainly deployed to improve network coverage and at the same time improve on capacity as well. (closed femtos) • There is considerable planning effort from the operator in deploying a femtocell network. • However in the coming years it is predicted that there will be more small cell deployments compared macro cells (Open femtos) Vodafone – To improve on 3G coverage Sprint Airave – To enhance CDMA coverage Source: www.vodafone.co.uk Source: http://www.sprintenterprise.com/airave/tellMeMore.html
  12. 12. Femtocells vs. Wi-Fi – Summary Wi-Fi • Seen as a cheap alternative for data offloading • Availability of Wi-Fi networks, High data rates and lower cost of ownership has made it attractive for catering to increasing data demand • However seamless interworking of Wi-Fi and mobile networks are still under consideration with more developments planned in coming years SK Telecom – Hybrid LTE + Wi-Fi femtocell AT&T – Wi-Fi hotzones Source: http://www.att.com/gen/general?pid=5949 Source: http://www.koreaittimes.com/story/20048/skt-attracts-global- telcos%E2%80%99-attention-innovative-lte-technology

  16. 16. Prospects in emerging marketsThe case for Wi-Fi has been reinvigorated by smart phones……… • Offers an immediate solution to the data crunch experienced by operators • More hotspots  Operators can partner with third party Wi-Fi service providers to improve on reach • In the immediate future Wi-Fi is more attractive  Until Voice over LTE becomes a reality , data demand can be met by an expansive Wi-Fi network
  17. 17. Content Overview of femtocells and Wi-Fi 1 From the perspective of current Telco landscape Femtocells vs. Wi-Fi 2 Conflict or Complement? Prospects in emerging markets 3 Selecting the “right” technology Trending……. 4 Hotspot 2.0, Data off-loading, The connected home…….
  18. 18. Trending……. 3G like end user experience to Wi-Fi authentication and roaming Hotspot 2.0 and 3GPP standardization on Hotspot 2.0  EEE 802.11u, Wi-Fi Protected Access 2 (WPA2)-Enterprise and standards-based Extensible integration of non-3GPP access networks Authentication Protocol (EAP) 3GPP  Non 3GPP IP access to EPC, Mobility management mechanism s for IETF Networks Connected home – The digital revolution happening at home Wi-Fi capable consumer electronics devices and The Future Home - The place of Wi-Fi and technologies such as DLNA/UPnP has made Wi-Fi a femtocells in home networking prominent technology How can the operator be part of this? – bundling of Wi-Fi and cellular services Sharing of end user backhaul connectivity for Wi-Fi Extending the footprint – The operator (e.g. BT FON) as well as femtos. strategy Partnering with third party providers on Wi-Fi etc
  19. 19. Conclusion Femtocells Will serve as a strong solution for coverage extension (3G / 4G) Predicted  there will be more small cells deployment by operators in future compared to macrocells (4G data networks) Can also become a strong data offloading solution  But yet to materialize Wi-Fi Is becoming a strong solution for data offloading! With planned developments (Hotspot 2.0 etc) may evolve to become an integral part of operator network and solution offering Combos Femtocells In the long run………… Wi-Fi
