3. Presentation Title 3 1/27/2016 Lucent Technologies - Proprietary WAP (Wireless Application Protocol)

4. Presentation Title 4 1/27/2016 Lucent Technologies - Proprietary Gateway Functions The WAP gateway is the link between the wireless and the "web" world, basically giving the WAP device access to the common internet. Converting the markup language (WML) from textual format to tokenized (binary/compressed) format which is readable by the WAP device. Translating the requests from the WAP device to HTTP requests for the "web" world. Convert between the SSL encryption used in the "web" world and the WTLS encryption used in the WAP world. Convert between the "transport" protocol of the "web", TCP, and that of the WAP world, WDP.

6. Presentation Title 6 1/27/2016 Lucent Technologies - Proprietary WML (Wireless Markup Language) Based on XML standard Like HTML, WML is read and interpreted by a browser built into the WAP enabled devices. Requires very little bandwidth resources compared to HTML. Requires relatively low processing power to render. Very suitable for the small displays on devices such as mobile phones. WML Pizza order application

15. Presentation Title 15 1/27/2016 Lucent Technologies - Proprietary Future Work Add more voice control to the browser, by enabling voice browsing commands such as moving forward and backward and user defined buttons. Move the front end signal processing module to run locally on the PDA and send only the speech features instead of sending the raw speech recording Implement a local compact ASR running in the PDA for small vocabulary tasks and make remote ASR only for large vocabulary tasks, such as email dictation. Porting the current implementation to WAP 2.0 new standard.
