Development and Systems Integration Issues for 3G Applications
There are a number of
application integration issues and considerations that developers must
consider:
-
Selection of the most
appropriate device and operating system platform - this should be
based on the target application requirements, availability of
development tools, development experience base of the team, and
many more
-
Selection of
communications gateways that can handle different implementations
of 3G networks - GSM/GPRS, 1xRTTCDMA, Edge and full-fledged
UTMS networks.
-
Support in appropriate
application servers like IBM's WebSphere, BEA's WebLogic, Oracle's
9i and Mobileum's iPlanet.
-
Whether the
application will have both real-time always-on capability and
offline capability in case of poor coverage, lack of coverage
-
Software support for
roaming in and out of networks including wireless public hot spots
(WiFi LANs) and wide area wireless networks
-
Selection of server
platform - Microsoft Windows, Sun's Solaris, IBM's AIX ,
etc.
-
QoS (Quality of
service) in terms of performance as measured by the number of
transactions the server can handle per second, response time
(transit time through various layers of communications,
application server and database software)
-
Role of any
specialized mobile Middleware, if appropriate
-
Compatibility with
existing software architecture employed by the carrier or the
enterprise

and, More
