majority of mobile subscribers rely on second-generation mobile technologies,but service providersare investing billions of dollars into aggressive rollouts of 3G,HSPA,EVDO,WiMAX and LTE to deliver a fully-featuredwireless Internet.With subscriber numbers projected to triple and exploding data traffic,it is critical that serviceproviders maximize their return on investment for the massive capital expenditures that are underway.,The“wireless Internet”is a term that refers to a range of technologies and applications.People who read web pageson WAP browsers or with Opera on their smartphones are participants in the wireless Internet;more specifically,theylikely have a data subscription with their mobile phone provider and are surfing whats known as the“mobile Internet”.A stranger in the park using a 3G wireless aircard(or USB“dongle”)to connect her laptop to the Internet is also usingthe mobile Internet.,To subscribers,the Internet is the Internet,whether its accessed through a wire or over wireless spectrum.Manysubscribers dont differentiate between cable and DSL,and history suggests that subscribers will view wirelesstechnologies as one.,With network convergence becoming a closer reality with each passing day,the requirements placed upon each part ofthe network are gradually shifting.Subscriber habits will hugely influence the capital investments required to deliver aquality experience,and the notion of one Internet has massive ramifications for service providers.,Network operators are making infrastructure investments to satisfy the growing appetite of subscribers,pressuring thebottom line.Furthermore,mobile service providers are grappling with falling voice ARPU(average revenue per user)and are exploring ways to offset those declines by introducing usage-based plans that increase data ARPU.Additionally,many operators are trimming operational expenses by improving network efficiencies.With mobile video rapidlybecoming a necessity in the same manner as mobile voice did just a few years ago,it promises to be a major piece ofthe puzzle for service providers.,Because so many subscribers currently rely on second-generation mobile technologies,there is a long way to gobefore 3.5G+and LTE networks are the norm.With such major distance left on the path to an everywhere broadbandInternet,there is a great deal of opportunity remaining for service providers worldwide.,Sandvines analysis of global mobile Internet traffic identified a number of high-level findings that will influence howwireless operators prioritize their investments:,Mobile data networks are experiencing congestion:service providers must investigate the cause and location(forexample,radio access network,aggregation or backhaul)to formulate effective network management policiesFlat-rate billing does not align with subscriber usage,which is hugely disproportionate:the top 5 percent ofsubscribers account for 50 percent of traffic,Subscriber behavior is extremely variable:there is a major opportunity for service providers to introducepersonalized services that incorporate consumption-,event-and time-based parameters,Time-sensitive traffic is a major component of mobile data,but it competes with bulky applications:YouTube andgeneric Flash video are the dominant forms of on-demand entertainment,but P2P filesharing is prevalentThe mobile Internet connects lives:social networking is massively popular,accounting for up to 9 percent ofutilized bandwidth during periods of peak bandwidth utilization,At the core of successful mobile Internet strategy is sufficient data to make informed decisions regarding service plans,management policies,capital investments and premium services.Service providers have long since had access todetailed information from billing and operations systems,but only recently is that information being combined withapplication-level awareness of per-subscriber Internet usage.,Sandvine calls this level of insight“network business intelligence”,and with it service providers can combineapplication-level,subscriber-aware network data with financial objectives,assumptions and data from billing systemsto accurately model network operation at a business level.,Accurate application-level information is useful in and of itself,but it becomes extraordinarily powerful whencombined with business and subscriber data already available to service providers.By understanding the dataon the network,service providers can make more informed business decisions.When information such as usagecharacteristics,element utilization,and subscriber demographics is readily available,service providers are able to,2,implement optimized network management policies and can introduce new revenue streams such as premium serviceswhile satisfying the diverse needs of a growing subscriber base.,A network business intelligence solution can help network operators to answer questions like:,Where is the optimal place to spend each dollar of available CapEx?,What is the definition of subscription packages that maximizes revenue while having no more than 5 percent ofsubscribers experience overage charges?,Where are the sectors experiencing the most concurrent sessions,and which of those have the most subscribers?The data examined in the remainder of this report is truly just scratching the surface of what is possible.Serviceproviders with traffic identification and network business intelligence solutions in place can explore their networkusage in fantastic detail enabling managed accounting based on data and can maximize profitability while at thesame time maximizing subscriber experience.,3,Table of Contents,Executive Summary Connecting Lives with The Everywhere

technologies and applications.People who read web pageson WAP browsers or with Opera on their smartphones are participants in the wireless Internet;more specifically,theylikely have a data subscription with their mobile phone provider and are surfing whats known as the“mobile Internet”.A stranger in the park using a 3G wireless aircard(or USB“dongle”)to connect her laptop to the Internet is also usingthe mobile Internet.Providers of WiMAX(802.16-2004“fixed WiMAX”)typically identify more with cable and DSLproviders than mobile data providers,but the Internet service is still delivered through the air.The same is true forproviders of satellite Internet,who are known for servicing areas where laying wires is cost-prohibitive,but haveincreasing presence in traditional broadband strongholds.Providers of WiMAX(802.16e-2005“mobile WiMAX”)havea great deal in common with traditional mobile data providers,although mobile WiMAX networks typically have muchlarger proportions of laptops,which has a huge influence on the traffic and usage profiles.Confusing matters further,many devices are able to connect to different wireless standards,blurring the lines betweennetworks.Additionally,the emergence of femtocells and the prevalence of WiFi hotspots continue to increase theoptions for subscribers.While providers are fully aware of the inter-operability and limitations of each technology,many users remain oblivious to the differences.To subscribers,the Internet is the Internet,whether its accessedthrough a wire or over wireless spectrum.Much like how many subscribers dont differentiate between cable and DSL,history suggests that subscribers will view wireless technologies as one perhaps even more so given that there isnt apiece of wire coming out of the wall to aid in the differentiation.“The Internet on Mobile”and“The Mobile Internet”2Beyond the physical infrastructure defining the network hardware,theres the fuzzier concept of the bits and bytesthat make up the network in a content-sense.Informa describes the modern Internet as the superset of the“MobileWeb”and the“Fixed Line Web”3.The distinction between the two is significant,and can also be described as theMobile Internet versus the Internet on Mobile.Figure 1-The Evolution of the Internet as Mobile Content Increases4While the Mobile Internet is comprised of services and applications specifically targeted at mobile devices(andtypically optimized accordingly),the Internet on Mobile is just that the traditional Internet(in all its high resolutionbandwidth-intensive and jitter-sensitive glory)delivered over a wireless network to a mobile device with limitedprocessing power and display capabilities.Morgan Stanley,in their“Mobile Internet Report”identified five trends that are converging to define the mobileInternet5:3G and LTE networksSocial Networking,Video,Voice-over-IPImpressive mobile devicesRoss,Jamie.The Mobile Internet Is 10 Year Old:Its Time for a Reality Check.Informa Telecoms&Media.Ross,Jamie.The Mobile Internet Is 10 Year Old:Its Time for a Reality Check.Informa Telecoms&Media.Ross,Jamie.The Mobile Internet Is 10 Year Old:Its Time for a Reality Check.Informa Telecoms&Media.Morgan Stanley Mobile Internet Report.6,6.,7.,8.,9.,10.,11.,12.,13.,14.,15.,16.,Of the five trends,social networking and video6 also exert huge influence on traditional broadband networks,with real-time entertainment emerging as the dominant form of traffic on the Internet7.With a common use case,in this casevideo,being a primary driver of increasing data levels on both wired and wireless networks,the lines separating wiredfrom wireless will quickly be washed away by a sea of on-demand entertainment.,The rapid evolution of mobile devices is also a major factor that is defining the traffic make-up on wireless networks.Modern smartphones offer a browsing experience approaching that found on a traditional computer,and thecompetition between hardware,software,and operating system manufacturers is driving innovation.The most populardevices will find a balance between quality and convenience that delivers a“good enough”Internet experiencecombined with the added features(such as locality)of the mobile age.,With network convergence becoming a closer reality with each passing day,the requirements placed upon each part ofthe network are gradually shifting.Subscriber habits will hugely influence the capital investments required to delivera quality exper
