  4. 4. Mobile data exploding – Random scary statsMedian smartphone data usage at The heaviest users of mobile dataAT&T was up 888% and up 551% at watched videos 40% of the time,Verizon this past year. surfed the Web an additional 20%, and used up the rest of theirIn 2009, the top 3% of heavy users online time in e-mails, socialgenerated 40% of wireless networking, file sharing andnetwork traffic. Now, these users software downloads.account for 70% of the traffic. Non-Confidential 4 © eXplanoTech Ltd.
  5. 5. Data Explosion: Myth and Reality Data traffic vs Revenues may not be as bad as initially thought Initial Prediction Traffic Revenues TimeThe mobile data is not growingas fast as was initially expected. Based on current data This does not mean that the Traffic operators do not have to worry about coping with the data demand Revenues Time Non-Confidential 5 © eXplanoTech Ltd.
  6. 6. The Good NewsThere is still a huge market for accessing internet/data on the phones Non-Confidential © eXplanoTech Ltd. 6
  7. 7. The Bad News Users want ‘true unlimited’ data plans from their operators WiFi is always the preferred choice of the users to access data: Its easy to setup and use in the modern devices Different reports point out that most of data from the tablets do not go through the operators networks More phone users are switching on WiFi for data usage Localytics, an App analytic company found in the USA that 89.7% of iPad sold are WiFi only. Among iPad’s with 3G connectivity 55% usage is over WiFi and in LTE iPad’s, 64% usage is WiFiInfograph Source: http://www.localytics.com/blog/2012/only-6-of-ipad-app-sessions-on-cellular-connection/ Non-Confidential © eXplanoTech Ltd. 7
  8. 8. The problems summarised Operators UsersHow to generate more revenue How to get cheapest possibleand recoup investment in Next- (unlimited) data plan withG networks fastest possible access (4G)How to get more users to use How to avoid ‘Bill shock’ andthe mobile networks reduce network usageHow to optimise the networks How to get better coverageso there are no bottlenecks and reduce latencyIncrease network capacity to Why does the loading of pageshandle more users fail sometimesBetter cell edge coverage for Why does loading of pages takethe users too much timeHow to monetise the usage of How to get access to more WiFiWiFi hotspots without paying and worrying about login & security Non-Confidential © eXplanoTech Ltd. 8
  9. 9. ‘Network Capacity’ calculationNetwork = Quantity of x Cell x Number ofCapacity Spectrum Spectrum Cells Efficiency (bps) (Hz) (bps Hz-1) Non-Confidential © eXplanoTech Ltd. 9
  10. 10. Since 1947 ‘Network Capacity’ has increased by a Million Non-Confidential © eXplanoTech Ltd. 10
  11. 11. But Data Usage has exploded as well The easiest way to cope with this explosion is to increase the number of cellsThe easiest way to increase thenumber of cells is to have moresmall(er) cells. Non-Confidential 11 © eXplanoTech Ltd.
  12. 12. ‘Small Cells’ to the rescueSmall Cells has to happen: To improve speeds for users on Macro and on ‘small cells’ To offload traffic and improve capacity of the network To improve coverage by reducing interference Non-Confidential 12 © eXplanoTech Ltd.
  13. 13. But other problems may ariseOperators expect users to pay for the ‘Small Cells’ butmost users expect them for free, especially business usersIf ‘Small Cells’ are not planned properly then they cancause interference with the network and create coverageblack holesThe data traffic still has to go through the operatorsnetwork and handling high amounts of data can still be aproblem for the operatorThe ISP’s are not happy with carrying operator traffic andmay cause problems or ask for compensationEven though the Access security is improved for the user,the operator is exposing the network to potential hackers Non-Confidential 13 © eXplanoTech Ltd.
  14. 14. ‘WiFi’ – The real saviour?Over 1 billion units of WLAN chipsets are expected to ship this year Expected to double by 2014Operators that have deployed Carrier WiFi China Mobile – 1 million hotspots by end of 2013 China Telecom – 1 million hotspots by end of 2012 SK Telecom – 60,000 hotspots by end 2011 Korea Telecom – 100,000 hotspots by end 2011 KDDI, Japan – 90,000 by Q2 2012Skyhook (a company that pioneered WiFi based positioning system)has already have over 250 million access points in its database [June2011]Australian operator Telstra closed their Carrier WiFi network in Feb.as they rolled out ‘Mobile WiFi’ based on LTE.

  15. 15. WiFi v/s Small Cells WiFi (802.11n) Small Cells (HSPA+/LTE)No Spectrum constraints Licensed Spectrum only40MHz available in the 2.4GHz Large bandwidths not alwaysband possibleLatency is better than mobile Latency not as good as WiFinetworksThroughput upto 600Mbps in HSPA+ DL in Rel-11 upto40MHz BW using 4x4 MIMO 672Mbps and LTE DL in Rel-10 upto 600Mbps in 40MHz BW using 4x4 MIMO.Radio cheap and already in Radio expensive and not asmost new mobiles, laptops and easily available in laptops andtablets. tablets.

  16. 16. Benefits of Carrier WiFi‘Offload’ mostly at traffichotspots like airports,shopping malls, etc.Reduced price data on ‘Pay asyou use’ schemes.Reduced price data roaminginternationally. MVNO’s cancash on this big time.‘Onload’ when the data speedsare low due to networkcongestion.Can be offered to subscribersusing non-cellular devices as‘perk’. Non-Confidential 16 © eXplanoTech Ltd.
  17. 17. New features in 3GPP standardsNew features are being developed by 3GPP that areintended to provide a value addition to the MobileBroadband offering and making it more integrated withWiFi for value additionLocal IP Access (LIPA) – Release 10Selected IP Traffic Offload (SIPTO) – Release 10IP Flow Mobility (IFOM) – Release 10Continuity of Data Sessions (CSN) – Study item in Release 12 Non-Confidential 17 © eXplanoTech Ltd.

  22. 22. TV White Spaces (TVWS)Main driver for TVWS is that they are in the sub 1GHzband that can increase coverage significantly Non-Confidential 22 © eXplanoTech Ltd.

  25. 25. Carrier Aggregation (CA)Contiguous and Non-ContiguousMulti-carrier Two 5MHz carriers in 2100MHz to make a 10MHz carrierMulti-band For example 5MHz from 2100MHz and another 5MHz from 900MHzLTE Inter-mode Carrier Aggregation Aggregating FDD and TDD bandsInter-technology Carrier Aggregation For example LTE & HSPA+Licensed-Unlicensed Carrier Aggregation LTE + WiFi Non-Confidential 25 © eXplanoTech Ltd.
  26. 26. Dynamic Spectrum Management (DSM) Non-Confidential 26 © eXplanoTech Ltd.
  27. 27. Things to remember for any Dynamic Spectrum Management TechniquesThe operator network would have to implement thetechnology but the devices would have to support thebandsThe Spectrum would be generally available for use by alloperators and maybe other devices/technologies and itwould also vary from one area to another. As a result acentral authority would be required to handle thisThe government/authorities would not let this spectrumbe used for free, forever. As soon as a workable solution isavailable they are bound to ask for some kind of fees.The whitespaces would be auctioned or sold in future andit would have to be decided in advance if there is a casefor using them for a certain duration of time.
