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 />

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.
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).
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.
Spectrum flexibility to scale channel size from 1.4 MHz to 20 MHz
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)
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.
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).
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.
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.
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)

Worldwide TrendsData Patterns<br /><ul><li>Expect 500 million smartphone unit shipments by 2015
Exponential growth in mobile data traffic</li></li></ul><li>Worldwide Trends<br />USA<br /><ul><li>AT&T & T-Mobile:</li></ul>No concrete plans for LTE. T-Mobile has adopted HSPA+ and has branded it as 4G.<br /><ul><li>Verizon: </li></ul> Has deployed LTE in major cities and is continuing roll out for more areas. <br /><ul><li>Sprint/Clearwire: </li></ul>Most active WIMAX player within the NA market. Largest 4G customer base in US market due to early mover advantage.<br />
Worldwide Trends<br />Europe<br /><ul><li>Sweden:</li></ul> Agressive launch plans by telcos to cover 99% of households with LTE coverage by 2012. Government recently auctioned 3 blocks of 2x10MHz spectrum within the 800MHz band.<br /><ul><li>UK:</li></ul>Only expected to start auctioning 4G spectrum licenses by 2012.<br /><ul><li>Germany:</li></ul>Rollout by Vodafone started for LTE.<br /><ul><li>Russia:</li></ul> Yota (largest WIMAX operator ) announced plans for LTE adoption.<br />
Worldwide Trends<br />Asia<br /><ul><li>China:</li></ul>China Mobile has been given approval to start trials in Shanghai, Hangzhou and 4 other cities. Has chosen to deploy TD-LTE.<br /><ul><li>India:</li></ul>Infotel has chosen to deploy TD-LTE.<br /><ul><li>Malaysia: </li></ul>Maxis and Celcom announced trials for LTE. Recently P1 was reported planning to switch from WIMAX to LTE.<br /><ul><li>Singapore:</li></ul> Government plans to re-allocate bands within the 2.3/2.5GHz spectrum to be available after 2015. Allows existing spectrum holder to offer LTE on existing spectrum.<br />
Emerging Technology TrendsCommunication Standards<br />White Space<br />700MHz/800MHz<br /><ul><li>US FCC has recently approved the use of spare guard band spectrum from TV broadcast for use.
IEEE 802.11AF is in the process of approval for Wi-Fi to use White Space spectrum.
Analog TV bands to be available for mobile cellular /broadbandusage once migration to digital TV is complete.</li></ul>HSPA+<br />Wi-Fi Offloads<br /><ul><li>Used primarily as a bridge from 3G to 4G.
From actual field tests done, speeds obtained can match LTE & WIMAX speeds under certain conditions.
Very strong headstart by WIMAX operators in Malaysia.</li></li></ul><li>Follow Frost & Sullivan on Facebook, LinkedIn, SlideShare, and Twitter<br />http://www.facebook.com/FrostandSullivan<br />http://www.linkedin.com/companies/4506<br />http://www.slideshare.net/FrostandSullivan<br />http://twitter.com/frost_sullivan<br />
