Transcript of Cdma2000 Technology Highlights David Crowe 2012 Technology Workshop Chair
cdma2000 Market Position
• More than 330 operators in 122 countries• Over 200 suppliers• Over 625 million subscribers
– Over 200 million using HRPD– Most devices shipped in 2011 included HRPD
• Integrates with LTE:– Many current LTE subscribers use dual-mode
cdma2000 devices

3GPP2 Role
• Develops cdma2000 specifications• Collaboration of 5 partners:
– ARIB (Japan), CCSA (China), TIA (USA), TTA (Korea), TTC (Japan)
– Partners publish specifications as national standards.
• Market Representation Partners– CDG, IPv6 Forum, Small Cell Forum, CDMA
Certification Forum (CCF)

1X Rev. E Capabilities
• Current release is Rev. E (2009): – 4x more voice capacity of Rev. 0, OR– 3x more 1x data capacity, OR– 70% increase in coverage
• EVRC-NW coder with 1/8 rate combines the benefits of EVRC-B and EVRC-WB.
• Many Rev. E capabilities are also available on Rev. 0 and Rev. A.

Rev. F Optimizations
• Air interface optimized for bursty M2M traffic:– Battery life increased 3-4 times– 3x more devices can be connected directly– 4x more indirectly connected devices
• Optimizations will benefit non-M2M capabilities such as SMS and USSD.

HRPD Capabilities
• Current implemented release is Rev. C (2010):– Forward link up to 14.7 Mbps (3 carriers)– Reverse link up to 3.1 Mbps (3 carriers)

M2M Capabilities
• cdma2000 has been used for M2M for years.
• Release F will allow operators to support more devices.
• Optimizations assume that most (not all) M2M traffic will be small, infrequent, downlink packets.

New Features
• USSD, compatible with GSM servers and applications
• Femtocells (legacy or IMS)• Location Based Services (legacy or IP)• SMS over HRPD• Self-Organizing Networks• Energy Efficiency (GREEN)• MSC Pools

Card Support
• Most current cards are R-UIM (SIM-based)• New developments focused on CSIM:
– Based on UICC platform– Application, coexisting with USIM etc.
August, 2012 cdma2000 Technology Highlights Slide 9
Numbering Issues
• Numbering was reviewed in the context of M2M:– cdma2000 is not dependent on MSISDN for data
services.– Hardware identifier numbering resources are
sufficient now that the transition from ESN to MEID is complete.
– Card identifier numbering resources are sufficient now that the transition from UIMID to EUIMID is complete.
– MIN has sufficient capacity

CDMA – LTE Interworking
• Many operators deploying LTE rely on cdma2000 for voice services, coverage and roaming.
• eHRPD is an extension of the 3GPP2 Enhanced Packet Core.
• Voice services generally supported using CS fallback to 1x CDMA or VCC (Voice Call Continuity).
