- 4. Why you'd care LTE is Faster LTE is Richer LTE is Safer LTE > 3G++
- 5. LTE is Faster SPEED AVERAGE LATENCY LIMIT SPEED ONEWAY 86/28 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 data Built 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 Mbps HSPA 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

- 26. App Development Best Practices
- 27. Plan for mix of networks 2G LTE 3G Your app can make intelligent choices based on network. Networks differ on bandwidth, latency, throughput, reliability, security, and more.
- 28. n Data 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. LTE's larger bandwidth and lower latency helps. credit: David Shankbone
- 30. Cache more often Your App Cache Be mindful about spikes in network traffic Try 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 without actually being active all the time * Concurrent media streams experience: start one while stopping the other, 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. Summary LTE represents a potential game changer; It creates opportunities for new killer apps. Accept the long term evolution and thrive. credit: KillDevil at Wikipedia
