Wireless QOS Backgrounder Wireless carriers controlthe spectrum or “last mile”- Come to grips with carrier weaknesses- Understand thatthese weaknesses are not going away soon As in the wired world, no two carriers are alikeWireless carriers don’tfeel competitive pressure toimprove Q OSCallfailure rates average 30%Do not compare wireless applications to wire line applicationsBroadband applications raise end-user expectations even furtherBlackMobileSys Confidential, 8/2000

Keys to Wireless Data QOSSet proper expectations (The next person to say, “Wireless Web” willbe shot) Use mature technologies-SMS, wireless data, 2-way paging Understand different wireless technologies - CD M A vs.GS M vs. paging Analyze specific carrier networks- AT&T vs. PageNet vs. France Telecom W ork with best-of-breed carriersPromote use of multiple devices for enhanced QOSProvide Point-to-point datatrackingDeliver measurable latencyBlackMobileSys Confidential, 8/2000
Quality of Service Tracking“When it’s absolutely, positively has to getthere .” Message and delivery tracking Real-time continuous measurement and logging of:– Message latency– Message delivery failure rate– Message throughput Ability to analyze data to determine:– Maximum message latency– Maximum message delivery failure rate– Troublesome modems, service providers, etc. Do you know how many messages got lost in the past week? Do you know what the average delay of delivery was to your devices?BlackMobileSys Confidential, 8/2000

Optimal Network InfrastructureNetwork Architecture Redundant, high bandwidth connections into major global carriers Priority routing into carrier network Continuous “pinging” of carrier networks to gauge availability Distributed,redundant data centers Redundant WAN and ISP connections Best-of-breed systems infrastructure Point-to-point encryption (SSL, IPSec)BlackMobileSys Confidential, 8/2000
Managed Network Services Global Network –Companies need messages delivered where their mobilepersonnel are Convenient Access ––Managed infrastructure includes multiple data centers (NOCs) and points-ofpresence (POPs)– Manage the carrier relationships – saves time, personnel, equipment, and 7/24/365 service –round the clock monitoring gives highest availability possible Service-level agreements provide measurable, quantifiable service Technology leadership - helps keep the customer current with new importantservices¾ Ultimately you must offer customers the greatest choice: device, protocol,carrier,technologyBlackMobileSys Confidential, 8/2000
