  1. The Digital CellularEvolution and its Impact on the Alarm Industry 2011-03-03

  2. Topics • Cellular Technologies and Their Evolution • Status of Digital Cellular • Impact on the Alarm Industry • Questions

  3. “GSM / UMTS” Family Evolution

  4. “cdmaOne / CDMA2000” Family Evolution * N=number of 1.25 MHz bands of spectrum used. If N=3, then this is called “3X EVDO”. Bands do not need to be contiguous!

  5. Current Generation GSM Family Evolution • Current ITU standards • No forward compatibility • GPRS radios cannot operate in EDGE mode • GPRS / EDGE radios cannot operate in UMTS mode • Backward compatibility, yes • UMTS radios can operate in GPRS and EDGE mode • UMTS standards kept modular by the ITU • To allow for easy removal of GPRS and EDGE • Technology transitions • HS*PA data transports use W-CDMA, not TDMA • LTE uses OFDMA and SC-FDMA • Radio cost and transition plan to deal with

  6. Current Generation CDMA Family Evolution • 1XRTT • 1XRTT shares band with EVDO Rev. 0 and Rev. A • EVDO (Rev. 0, A and B) • Rev. A changes uplink modulation • Enhances uplink data rate • Rev. B change modulations further • Further enhances date rate in both directions • Other • EVDO falls back to 1XRTT when EVDO not present • Within the same band • Just a different modulation scheme • EVDO Rev. B and 3X EVDO will not be deployed • Selection of LTE precludes them from consideration

  7. 4G … Long Term Evolution (“LTE”) • General • 1.25 MHz – 20 MHz spectrum requirements • Allows deployment when 5 MHz allocations not available • Has very high spectral efficiency • Getting closer and closer to Shannon’s Law limits • Is being deployed in new bands • To avoid cannibalizing existing services • LTE is not backwards compatible to UMTS • Different protocols – chipset cost & performance

  8. 4G … Mobile WiMAX • General • 5, 8.75 and 10MHz spectrum requirements • Slightly less flexible than LTE • Has very high spectral efficiency • Getting closer and closer to Shannon’s Law limits • Is being deployed in new bands • To avoid cannibalizing existing services • The term “WiMAX” includes multiple subsets • “Mobile WiMAX” (IEEE 802.16e) and “Fixed WiMAX” (IEEE 802.16d) for example • Their use purposes are quite different • “Fixed WiMAX” does not interop with “Mobile WiMAX”!

  9. Verizon • 1XRTT and EVDO Rev. 0 everywhere they have spectrum • EVDO Rev. A in most markets too • Will maintain 1X and EVDO through 2018 • Deploying LTE ahead of AT&T in the US • MetroPCSwas first to go commercial though • LTE is in 700MHz band • Using 20MHz channel • Many markets by end of 2011 • Fuller coverage by 2014 to 2015 • Decent spectrum position • 700MHz (20MHz available), 850MHz and 1.9GHz in many markets

  10. AT&T • GSM/GPRS/EDGE everywhere, HS*PA in most major markets • GPRS and EDGE performance • Became more obvious with iPhone 1 introduction • Temporarily masked by iPhone 3/3GS deployment • So, performance “improved” for other M2M customers • Planning to deploy LTE • Is a year (or more) behind Verizon • Has slowed (stopped?) their HS*PA expansion • Weakest spectrum position • 800Mhz, 1.9GHz and 2.1GHz in many markets • Needs to re-use 800MHz spectrum with more efficient technology • Puts pressure on GSM/GPRS futures

  11. Sprint • 1XRTT and EVDO Rev. A everywhere they have 1900MHz spectrum • Extensive roaming agreements to achieve comparable coverage to Verizon • Converting iDen spectrum to 1XRTT & EVDO Rev. A • Will provide 1XRTT and EVDO well beyond Verizon • First to go All-Digital and first to deploy 4G • WiMAX started in 2009 • Rapidly deploying WiMAX • All major markets by end of 2011, full coverage by 2012 to 2013 • Very likely to also deploy LTE • Best spectrum position • 800MHz, 1.9GHz and 2.5GHz (192MHz available)

  12. Technology Longevity • GPRS is slowly degrading in most markets • AT&T will selective re-purpose 800MHz spectrum for 4G … • By 2014– 2015, GPRS may have performance issues • Major markets likely to be impacted first • 1XRTT and EVDO longevity more assured • Verizon through 2018 … at least • Sprint will go longer than 2018 … possible 5 to 10 years • Using their iDEN 800MHz spectrum (30,000 towers) • HS*PA longevity somewhat unknown • Likely to start degrading by 2016+ as AT&T LTE happens • T-Mobile may go longer (in major cities) with HSPA+ • LTE and WiMAX are the [current] future • Verizon (LTE), AT&T (LTE) and Sprint (WiMAX and LTE) • Will be “data-only” for a while till VOIP is deployed • “All-IP” technologies are far easier to deploy and grow

  13. Does The Alarm Industry Need 4G? • Selective uses • You all are the experts here • Likely places • Full Video streaming, Inter-station transmissions, Other? • When is important • Industry needs to avoid the Analog transition issues • … the FCC is not likely to help with “5 year sunsets” this time • Radio costs are a concern • GPRS radios are very inexpensive today • But, module manufacturers are not introducing any new products • But, GPRS cost differential to 1X is decreasing • New 1X and EVDO radios are being released • HS*PA radios are generally more expensive than EVDO • W-CDMA chip cost scales just like CDMA • WiMAX and LTE radio costs are unknowns at this time • But may end up lower than HS*PA and EVDO radios later

  16. “Wireless is Less Reliable Than Landline!” • But … users and customers are saying otherwise • Landline-connected households continue to drop • In May, 2010: 25% residences withoutlandline • By 2014: 35-40% residences will be withoutwireline • Copper wiring in major cities is degrading slowly • Pressurized, paper-wrap wire bundles are failing • Water, time and exposure when repairing, is taking its toll • Very expensive to replace the copper • Albeit some replacement with optical fiber is occurring in major cities • In disaster scenarios … • Cellular stays working … • … or is brought back faster than landline • Wireless growth continuing • More cellular devices in use than population

  17. WiMAX is NOT related to WiFi • Confusion arises perhaps because … • Both terms begin with the letters “Wi” • Both standards begin with “IEEE 802.” • Both have “something to do with wireless data & the Internet” • WiFi • Is a short-range system (multiple meters) • Uses unlicensed spectrum • Is typically used for fixed-location Internet-access • Used for access to a network on “operator’s” own property • No hand-off when in motion • Is more analogous to “cordless phone” • WiMAX • Is a longer-range system (multiple kilometers) • Uses licensed spectrum • Has Mobile and Fixed variants for different purposes • Is more analogous to “cell phone”
