Why Beyond 1x Rev. 0/GPRS ?Why Beyond 1x Rev. 0/GPRS ?! Higher data rate applications

– Streaming Video

! To support new service paradigms – PTT

– Group Communications

! Broadcast & Multicast Services! To improve spectral efficiency and capacity

! To converge circuit & packet core network

! To support simultaneous voice and data! To improve reverse link data speeds

! To cover “Hot Spots” using WLAN



Why New Technologies in RuralWhy New Technologies in Rural

Markets?Markets?! Survival vs. Growth

– Where will new $s come from?!

New subscribers – Youth

– Enterprise

! New services to current subscribers

!

Competition! Customer Retention

! Roaming Agreements

– Voice roaming $s going down – Big partners will expect

! What business are you in? – Communication or Telephony

BCMCSBCMCS



What is BCMCS?What is BCMCS?

! BroadCast and MultiCast Services

– Ability to transmit same stream of information to all

or a selected group of Mobile Stations! Example services:

– Traffic/weather information with some advertisements

unconditionally delivered to MS in a region – Public service announcements in emergency

situations like Amber alerts, Tornado warning etc.

– Stock market tracker, Sports score tracker forrestricted subscribers

– Efficient delivery of Group PTT or chat sessions



BCMCS BenefitsBCMCS Benefits

! Efficient use of radio and network resources todeliver same contents to a collections of users

! Effective for different services with differentrequirements – Large number of users sharing a public

announcement stream during emergency situations

– Select group of users distributed in different parts ofthe network like live transmission of sports events

! Allows additional revenue creation opportunities

for the operator – Ability to support group communication services

– Advertisements added to common broadcasts
