• What is a Portal?
• What is a Wireless Portal?
• What Do I Need in a Wireless Portal?
• How Do I Get One?
• What Lies Ahead?

4
What Is A Portal?

• A consolidation of all the information needed to
  do your job
• Intranet or Internet
• Do I need one?

5
Why Are Portals Hot?

• Technology Availability
• Business Need
• Economics

6
What Is A Wireless Portal?

• A consolidation of all the information needed to
  do your job
• Everything in an Internet Portal?
• Okay, but

7
Where Is My Desktop?

• First all the information needed from my
  Desktop
• Email
• Calendar
• Contacts
• I need Exchange on my Wireless Device!

8
What Is Required?

• Technology Availability
• Wireless desktop access
• Business Need
• Timely, secure information
• Economics
• Cost vs. Benefit

High Speed Wireless WAN Future

• Key Facts
• 1. Ratio of Fibre Speed Cellular Channel Speed ?
  30,000,0001 (Fibre TDM_at_10 Gbps x 32 WDM vs.
  9.6K bps data over cellular)
• 2. Wireless bit rate is a linear function of
• i) spectral consumption
• ii) battery consumption
• iii) transmitting distance
• (There is no free lunch in physics)
• (Moores law does not apply to wireless)

Conclusion Wireless data must stay in its sweet
spot where the bit rate benefits are greater
than the bit rate costs.

3000 - 6000
Conclusion If you sent/received 100 messages/day
for one month, you would consume less economic
spectrum than one local phone call.

Wireless Device

• Small size
• Low cost
• Wide coverage
• Message notification
• Low latency
• Long battery life

What Is A Wireless Portal?

• A consolidation of all the information needed to
  do your job
• Start with a Wireless Desktop
• Okay, but

Internet Portals

• Technology Available
• same as Intranet technology
• Business Need Maybe
• driving directions, airlines, etc.
• Economics
• questionable as long as cost is non-zero

19
Summary

• Wireless portals starting from scratch
• Personal information, then
• Intranet information, then
• Internet information
• Security a must
• Economics drive value proposition
