Mobile Dual-Antenna Receive Diversity

Mobile Receive Diversity increases system capacityby improving the FL Signal to Noise Ratio

Higher data rates in larger portion of the coverage area DOr0 FL Sector Capacity = 850 Kbps

DOr0 FL + 2-Rx Diversity Sector Capacity = 1,240 Kbps

More practical in CDMA systems

Backward compatible with existing CDMA networks

Does not alter the attractive form factor of existinghandsets

Devices are equipped with 2 antennas (internal/externalcombination)

ZIF architecture and dual receiver chip sets provide greaterintegration

Receive Diversity also increases voice & data throug hput c apacity

QoS Software Upgrade: Prioritize ApplicationsApplication-Based QoS :

Enables system to treat users with different levels of priority based on thecurrent application utilized (e.g., Voice is high priority)

Users status elevated once high priority application launched Once status elevated, all of the users packets are treated in same high priority

manner Software upgrade to EV-DO Rel 0 networks

Rev A QoS Application: VoIP

Rev A QoS Enables Delay Sensitive Applications, such as VoIP

Telco Quality VoIP Performance Goals Comparable to 1x Circuit-Switched Voice 58 simultaneous users / sector (2-Rx diversity devices, PIC) Average mouth-to-ear delay

125 mSec (mobile to land) 175 mSec (mobile to mobile) Add approximately 50 mSec for 98 percentile case

VoIP Tests Underway, that if Successful (Simulationsare Quite Positive) may cause Growth in Voice Trafficto be Accommodated by EV-DO

VoIP allows Airlink to be used Flexibly between Voiceand Data, Especially as Data Traffic Continues toIncrease Voice becoming richer and more integrated with data and

video (e.g., Telco Quality VT) Operators can utilize idle voice capacity and clip-cast

multimedia content to user devices


14

Multimedia Multicasting InnovationsDriving Dow n the Cost of Mobile Multimedia Delivery

Enable multiple channels of the same video, audio and other content to bedelivered to large numbers of users simultaneously

Server, network and cell load are thus independent of total number of users. Increase capacity and reduce cost

16

EV-DO Platinum Multicast (proposed as TIA-1006-A)

Substantial capacity gains Approximately 3-4 times the capacity of EV-DO Gold Multicast 1.5 Mbps per sector with > 98% coverage

Much improved system economics Cost/bit transferred over the air

OFDM modulation incorporated into EV-DO TDM FL No RF changes Only baseband affected

Same network architecture and security mechanismsas Gold Multicast

Same upper layers

HSUPA (High Speed Uplink Packet Access) / EUL Enhance Uplink throughput rate

Theoretical up to 5.76Mbps Key Elements to support HSUPA include

Fast resource control mechanism (Node-B scheduling) Physical layer re-transmission (HARQ) Shorter transmission intervals (TTI)

Expected gains* 50-70% improvement of uplink sector throughput 20-55% reduction in user packet delay 50% increase in user packet call throughput

Combined with HSDPA, HSUPA offer high speed symmetrical datacommunications Best fit for apps such as video sharing and other types of peer-to-peer

services (such as VoIP etc..)

Standardization finalized in Release 6 at Feb 05

* The results are based on Qualcomm simulation
