Planning and Managing IT Infrastructure

Notes 4. Localization: The emergence of location-specific based applications will enable the user
to receive relevant information on which to act.
5. Instant Connectivity (2.5G): Instant connectivity or “always on” is becoming more
prevalent will the emergence of 2.5 G networks, GPRS or EDGE. Users of 2.5 G services
will benefit from easier and faster access to the Internet.

6. Personalization: The combination of localization and personalization will create a new
channel/business opportunity for reaching and attracting customers. Personalization will
take the form of customized information, meeting the users’ preferences, followed by
payment mechanisms that allow for personal information to be stored, eliminating the
need to enter credit card information for each transaction.
7. Sensitivity: Access to real-time information such as a stock quote that can be acted upon
immediately or a sale at a local boutique.

8. Security: Depending on the specific end user device, the device offers a certain level of
inherent security.

9.1.2 Disadvantages of M-Commerce

The disadvantages of m-commerce are discussed as below:
1. Mobile devices offer limited capabilities (such as limited display). Between mobile devices
these capabilities vary so much that end user services will need to be customized
accordingly.
2. The heterogeneity of devices, operating systems and network technologies is a challenge
for a uniform end user platform. For this reason, standardization bodies consisting of
telecommunication companies, device manufacturers and value added service providers
integrate their work.
3. Mobile devices are more prone to theft and destruction.

4. The communication over the air interface between mobile device and network introduces
additional security threats.

9.2 Mobile Commerce Framework

Figure 9.1 shows our framework for mobile commerce, which lets companies strategize and
create mobile commerce applications. The framework defines several functional layers,
simplifying the design and development so that different parties—vendors, providers, designers,
and so on—can address individual layers. By using this framework, a single entity is not forced
to do everything to build mobile commerce systems, but can build on the functionalities provided
by others.
