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

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
