4G: LTE vs WiMAX

  1. 1. 4G – LTE vs WIMAX<br />Technical Insights’ Growth Opportunity Briefing<br />Future Trends in the Mobile Cellular Space<br />Richard Van<br />Research Analyst, Technical Insights <br />April 19, 2011<br />
  2. 2. Table of Contents<br />1<br />Introduction<br />2<br />Technology Overview – LTE & WIMAX<br />Technology Landscape in Malaysia<br />3<br />Emerging Technology Trends<br />4<br />5<br />Conclusion<br />
  3. 3. Introduction<br />Cellular 4G<br />Original specifications for 4G specifies speeds exceeding 100Mbit/s.<br />None of the current 4G technology currently meets those specifications but are marketed as 4G as they represent substantial improvement over 3G and represent forerunners to actual 4G technology. <br />We will discuss the capabilities of the current forms of LTE (Long Term Evolution) and WIMAX (Worldwide Interoperability for Microwave Access)<br />WIMAX<br />LTE<br /> HSPA+(3.5G)<br />

  6. 6. Technology OverviewLong Term Evolution (LTE)<br />About<br /><ul><li>Officially know as the 3GPP Long Term Evolution which is the latest standard under the technology tree that produces the current GSM technology.
  7. 7. Marketed as 4G but is actually a pre-4G standard to the precursor of LTE Advanced. Designed to be forward compatible with LTE Advanced using the same frequency bands but is not backward compatible with existing 3G systems. </li></ul>Bandwidth<br /><ul><li>Theoretical download rates of 326.4 Mbit/s for 4x4 antennae, and 172.8 Mbit/s for 2x2 antennae (utilizing 20 MHz of spectrum).
  8. 8. Theoretical upload rates of 86.4 Mbit/s for every 20 MHz of spectrum using a single antenna.</li></ul>Spectra<br /><ul><li>Capable of supporting up to 200 users per 5MHz.
  9. 9. Spectrum flexibility to scale channel size from 1.4 MHz to 20 MHz
  10. 10. 700 and 1900 MHz in North America; 900, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; 1800 MHz in Australia.</li></ul>Range<br /><ul><li>At 900MHz band, range from 5km (optimum) to 100km (acceptable)
  11. 11. At 2.6GHz band, typical range is 1km.</li></li></ul><li>Technology OverviewWorldwide Interoperability for Microwave Access (WIMAX)<br />About<br /><ul><li>Officially designated under the IEEE 802.16 standard.
  12. 12. Designed as an extension of the Wi-Fi technology giving further range for broadband connections, cellular backhaul, hotspots. Most commercial deployments cater for Mobile WIMAX.</li></ul>Bandwidth<br /><ul><li>Theoretical maximum speeds of up to 75 Mbit/s (utilizing 20 MHz of spectrum).
  13. 13. Latest ratification of the 802.16m standard (WIMAX-2) capable to reach speeds of 300Mbit/s. </li></ul>Spectra<br /><ul><li>Spectrum flexibility to scale channel size from 5MHz, 8.75MHz or 10MHz.
  14. 14. 2.5GHz in North America; 2.3GHz – 3.5GHz in Asia. </li></ul>Range<br /><ul><li>Theoretically capable up to 50km depending on frequency and line of sight.
  15. 15. Typical deployment at 5-8 km range.</li></li></ul><li>4G Players in Malaysia<br />List of Industry Players in Malaysia<br />WIMAX<br />LTE<br /><ul><li>P1 WIMAX (Green Packet)
