Wireless Architecture – Web Clipping
![Page 35: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/35.jpg)
Wireless Architecture - DMZ
![Page 36: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/36.jpg)
Wireless Architecture—Security
Should incorporate or support:
• Automatic session timeout
• No proprietary data or passwords reside on PDA
• Elliptical curve encryption SSL (HTTPS 128-bit Secure Socket Layer)
• Server-side audit logging
![Page 37: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/37.jpg)
Wireless Architecture—Security
Should incorporate or support:
• Mandatory password authentication
• Oracle roles to limit access to specific users or areasof database
• Read-only permission option
• Encryption maintained on proxy server;no data caching
![Page 38: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/38.jpg)

Major Wireless Standards
802.11
• Allows for wireless connectivity over LANs
• 802.11 is an extension of Ethernet to wirelesscommunication
• The client requires hardware—usually a PC Card or PCI card
![Page 41: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/41.jpg)
Major Wireless Standards
Bluetooth
• Short-range radio link designed to “replace the cables connecting portable and/or fixed electronic devices”
• Not a wireless network per se
• Operates via a radio unit
![Page 42: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/42.jpg)
Major Wireless Standards
WAP
• Would like to be the de facto standard for providing internet communications and advanced telephony services on mobile phones and pagers.
• WAP has NOT been widely adopted.
![Page 43: Managing Databases In a Wireless World](https://reader036.fdocuments.us/reader036/viewer/2022062514/5589b595d8b42a21598b46dc/html5/thumbnails/43.jpg)
• 2.5G and 3G are being deployed in major markets across the U.S. Don’t expect 3G wireless to be available in all of the primary U.S. markets until mid-2003!
• To users, 2.5G and 3G will mean a 4-fold increase in transmission speed and a larger pipeline to transmit security encryption and data simultaneously.
