1. Mobile data consumption is growing exponentially and doubling every year, far exceeding original projections. Video content like YouTube is a major driver of this growth. 2. Wireless operators must plan their network access strategies to accommodate this rapid growth. Early strategies include utilizing 4G networks, WiFi offloading, and optimizing networks through congestion management and smart planning. 3. WiMAX was developed to support high-speed wireless data and address this growth. It has evolved through multiple releases to improve throughput, capacity, and support new frequencies and channel bandwidths up to 100 MHz.

Driving factors for Wireless Access Networks 2
The last decade of mobile industry Are you ready for the data opportunity?
1 Adoption follows Availability 4932% data growth after WCDMA moved to HSPA.
2 Continued trends in new 4G Networks CLEARWIRE – 7 Gig Average YOTA – 10 Gig average The average data consumption has surpassed 10 Gigabytes in new 4G wimax networks , beating predictions
3 Data surpassing all projections CISCO Predicted in 2009 Measured Data in 2009 Average User Consumption 30.0 3 20.0 2 15 10.0 0.3 0.5 0.8 1.2 10 11.4 3.1 4.7 6.8 10.0 15 23 5 10 7 0.0 0 2010 2011 2012 2013 2014 2015 Cisco VNI Yota Clearwire 3Q 1009 •Global Average in 2009 : 3.1 GB/Mo • Measured with Collaboration of top 20 operators : 11.4 Gigs •Global Average in 2010 : 4.7 GB/Mo • Adoption follows availability : 10 Gigs •Global Average in 2015 : 23 GB/Mo average in new WiMAX RAN in Russia For all practical purpose data is surpassing all predictions carried earlier and we can expect it to double every year by next decade.

5 Applications driving usage Average Iphone user in US .4 to .5 GB/Mo Watch a DVD quality Movies 1 to 2 GB Listen internet Radio 30 min/day .5 to 1 Gig/Mo Download Music .5 to 1 Gig/Mo Watch 30 Min You Tube 5-6 to GB/Mo Upload Video to Face book 1 GB Sync 10X photos with Flickr 2-3 GB Video, social networking, and collaboration is generating most of the monthly user traffic
6 Social drives media explosion FaceBook - 20bn photos online, 2bn added per month - 1bn links to video added per week - 1.2m photos viewed per second - 217m videos per month Individuals like sharing their media online Flickr - 4bn shared photos - 0.5bn new per month Facebook has an estimated 25 billion pictures, or about ~80 pictures per member MySpace - 90GB of music, pictures, - video per second 31 24 YouTube 16 -1bn Videos viewed per day -PhotoBucket Share photos on Share Photos Share Video - 6.2bn photos shared social networks on other sites
7 4 Video driving internet data consumption Video 66% of the total traffic by 2014 4,000,000 3,500,000 Web/Data 3,000,000 VoIP 2,500,000 Gaming 2,000,000 P2P 1,500,000 Video 1,000,000 500,000 0 2009 2010 2011 2012 2013 2014 P2P traffic is still growing in absolute terms but ,Video is growing at a CAGR of 131 percent.
8 Old friends : Busy hour and Top 10 % consumers Top 10 % consumes 60% of the internet bandwidth and busy hour traffic is 1.6 times
9 Devices driving consumption A Smart phone generates as much as traffic of 30 basic phones One laptop generates as much as traffic of 450 basic phone Almost 80% of the traffic by 2013 will be generated by devices which are 3G and above. Half of the traffic will be from laptops/Netbooks.
Section 1 Summary • Mobile data will roughly double every year by 2020. • Operators will have to plan their access strategies consistent with the growth projections. • I would say , “Opportunity filled with challenge”
