Lucent’s 3G HSD Products Enable
Operators to Provide Ubiquitous Coverage
• Mobile Professionals Tell Us:
– Service Must be Available Wherever and Whenever They Need It
– They Will Sacrifice Bandwidth For Mobility
– 802.11 Must Be Integrated Into the Solution
3G Operators Own the Wide Area Networks Required to
Complement 802.11 Deployments and Offer The Ubiquitous
Coverage It Needs to Be Viable

Capacity/Coverage Curves for 3G 1X Data
• 3G 1X supports varying speeds of packet data using supplemental
chnls.
– 9.6, 19.2, 38.4, 76.8, 153.6 kbps
• A system with all data users will have significantly different capacity and
coverage than a system with all voice users
• In addition, voice and data users on the same system will change the
9 capacity and coverage as well

Factors to consider for supporting data
applications
• In designing for data applications (either all data or voice/data mix),
results will depend critically upon:
– characteristics of data and characteristics of data user (often unclear)
– mix assumed in design (many combinations possible!!)
• Consider (example) Email. Characterization issues include:
– proportion of traffic that is due to data
– proportion of data users that are fixed and mobile
– proportion of data users that tend to transmit rather than receive
– behavior of data user:
• bursty (log on and occasionally send/transmit messages)?
• continuous (log on, download Email, log off)?
• Performance can be computed for any set of assumptions, but
assumptions cannot be enforced. Specific data application can help
determine assumptions
