Slide 4: Forecast for mobile data traffic
Forecast for mobile data traffic Increasing use of bandwidth from mobile phones Studies from Ericsson and Cisco predict exponential growth of bandwidth need, driven largely from video consumption Drivers i.e. are TV Anywhere and widely usage of tablet PC & smart phones For Tablet PC using HE
Slide 5: Which networks can do the job for mobile & portable reception?
If it comes to mobile & portable reception – which networks cando the job? UMTS / LTE Terrestrial DTV WiFi Long Term Evolution Limited success to include WiFi experiences congestion in (LTE) in Unicast mode broadcast tuners in mobile many built-up areas, especially Not with moderate costs de
Slide 6: Is LTE eMBMS ready for this challenge?
Is LTE eMBMS ready for this challange? eMBMS = evolved Multimedia Broadcast Multicast Services Point to Multi Point (P2M) broadcast and multicast in 4G LTE networks Only 60% of LTE cell data rate can be used for eMBMS (6 of 10 Sub-Frames) because Unicast needs to be present too (fixed in the s
Slide 7: LTE Mobile Offload
LTE Mobile Offload Cellular networks will probably not be able to cope with the growing demand for data like live video and will not be efficient to distribute live video and audio @ 1.4 Mbit/s or more in thousands of networks cells and possibly by several mobile network operators in parallel Le
Slide 8: What is LTE Mobile Offload (LMO)?
What is LTE Mobile Offload (LMO)? Technology envisioned / created by the Technical University of Braunschweig. Also known as “Tower Overlay” GatesAir has partnered with TUB to commercialize Basic idea is to offload popular services, especially live video, from cellular networks Utilizes High
Slide 9: Technical Fundamentals
Technical Fundamentals Tower Overlay with DVB-T2 using Future Extension Frames (FEF) DVB-T2 Future Extension Frames (FEF, defined in the DVB-T2 Standard) enable time domain spectrum sharing with other wireless networks, e.g. a mobile access network Re-use of DVB-T2 as existing wireless carrier t
Slide 10: Technical Fundamentals – Hybrid Modulator
Technical Fundamentals – Hybrid Modulator A hybrid modulator / exciter can therefore be realized that broadcast DVB-T2 to fixed (home) receivers while video over LTE can be broadcast to mobile receiver DVB-T2- Modulator DVB-T2 Data Standard DVB-T2 content DVB-T2 FEF- DVB-T2 FEF- DVB-T2 FEF- Time
Slide 11: Hybrid Modulator
Hybrid Modulator The LTE in-band signaling (via unicast network) instructs the LTE receiver that a P2MP LTE carrier exists that it can receive and decode at the broadcast frequency being used. Proprietary and confidential. | 11 Connecting What’s Next
