11. Application Layer
Vertical applications: those apply to a function part of an industry such as field sales and field service, or to specific market segment such as banking or health care
Horizontal applications: apply to many people across most market segments
2019/2/19
Prof. Huei-Wen Ferng

12. Operation Systems Layer
This layer provides tools for application programmers to access different mobile devices and different wireless networks
A key layer to rapid growth of wireless networking and proliferation of applications
2019/2/19
Prof. Huei-Wen Ferng

13. Device Layer All the mobile devices we carry with us:
Notebooks (NBs)
Personal Digital Assistants (PDAs)
Cellular phones
Personal communicators
Combination devices
Combination devices are now rapidly emerging
2019/2/19
Prof. Huei-Wen Ferng

14. Wireless Networks Layer
The Wireless Wide Area Network (WAN) is also called “Mobile Data” including:
Packet networks: RAM/Mobitex, ARDIS/Modacom
Paging networks
Data over cellular: CDPD (over AMPS), GPRS (over GSM)
Data over satellite
Wireless LANs: with much higher rate but smaller coverage than Mobile Data networks

22. Challenges Security Bandwidth Software Safety User authentication
Data privacy
Privacy of user location
Bandwidth
Limited bandwidth (10K~10M)
Software
Still in its infancy
The main/ biggest reason for late data implementations
Safety
Radiation is harmful to human beings
Trends: low power, thus less radiation

35. What is LBS Platform ? LBS platform is a spatial information computing
environment that developers can use of APIs
that it provides to deploy LBS applications.
The developers need not to know too much
about spatial computing and spatial data and
database.
