Every once in a while a new technology changes the game. Some benefit from it while others fail to adapt. Long Term Evolution, or LTE for short, is on the surface ,just yet another fast wireless standard bringing us faster mobile networking. But just like the freeway was much more than just a faster road, LTE actually has a chance to change the rules for app developers and create new possibilities.

  • 3. What LTE Is
  • 4. Why youd careLTE is FasterLTE is RicherLTE is Safer LTE > 3G++
  • 5. LTE is FasterSPEED AVERAGE LATENCY LIMIT SPEED ONEWAY86/28 12/5 15 Mbps Mbps ms Faster! Over 50%LTE enables Video sharing, conferencing, HD streaming.
  • 6. Much more bandwidth 3G LTE 1.25MHz - 5MHz 1.4MHz - 20MHz e for dataBuilt for voic Built
  • 7. Latency Reduction 65 ms 50 ms Low latency 10 ms 10 ms => High speed apps HSPA HSPA+ LTE LTE WiMAX MIMO2x2 MIMO4x4 Higher peak rates (theoretical) 173 Mbps High peak throughput 86 Mbps => Rich content 55 Mbps 42 Mbps 14 Mbps 11 MbpsHSPA 5MHz HSPA+ 5MHz Credit: Alcatel-Lucent
  • 8. LTE is Richer * HD video * Multipart video * Real time gaming * Cloud computing * Enhanced reality
  • 9. LTE is Richer 3G LTE vs. IPv4 IPv6 N -10- digit MD 15-dig it IMSI identifier based i dentifier
  • 10. LTE provides for Quality of Service.Slower traffic yields to faster packets. Such as video conferencing.Your app can take advantage of this.

  • 12. Simplified Worldwide Roaming LTE is unifying standard providing seamless international roaming & device economies of scale
  • 13. LTE is Safer* Network authentication (128-bit keys)* SIM robust and non-invasive key storage* RAN encrypted data communication to prevent eavesdropping
  • 14. More Security Features* Identity protection (IMSI/IMEI) against snooping & alteration* IpMS granular security per service* IPSec for secure tunneled IP communication

  • 25. Follow the money Source: Analysys Research
  • 26. App Development Best Practices
  • 27. Plan for mix of networks 2G LTE 3GYour app can make intelligent choices based on network.Networks differ on bandwidth, latency, throughput, reliability,security, and more.
  • 28. nData coming i Use bigger buffers LTE is faster than 3G so big buffers work better. True even when switching to and from 3G. r he buffe Data in t t Data going ou
  • 29. Pre-fetch for faster experience Anticipate and pre-load data user will want. Experiment with algorithm that works best for your app. LTEs larger bandwidth and lower latency helps. credit: David Shankbone
  • 30. Cache more often Your App CacheBe mindful about spikes in network trafficTry to use smart cache to mitigate for spikes
  • 31. One session for multiple GETs GET/Response Session GET/Response GET/Response* LTE was designed for long sessions* Old networks: Small but frequent requests* LTE: fewer requests->better responsiveness and lower latency* Group requests into single session
  • 32. Take advantage of all-IP network Start stream A Stop stream A Session Start stream B Stop stream B Start stream A* LTE: idle to active in 100ms -> always-on experience withoutactually being active all the time* Concurrent media streams experience: start one while stopping theother, as in voice over a scrolling map
  • 33. Favor downloading over streaming vs. ing g Downloa d Streamin Expect 2 to 8s delay when switching between LTE and 2G/3G. Streaming is also more expensive on battery.
  • 34. Avoid aggressive behaviour Aggressive App Other Apps* Aggressive behavior: continuously using network without consideration for others.* Results in tying up network resources and drains battery.
  • 35. SummaryLTE represents a potential game changer; Itcreates opportunities for new killer apps.Accept the long term evolution and thrive. credit: KillDevil at Wikipedia
