bank accounts.
WAP’s goal can be listed as following:
 Allow a wide variety of wireless devices and compensate for the restraints and applications.

 Utilize as few resources as possible on the handheld device and compensate for the
constraints of the device by enriching the functionality of the network.
 Enable a variety of devices, from the very basic handset to a fully featured PDA or laptop
PC, to access the same information and content.
The features supported by WAP software are the following:
 Multiple devices like Standard phones, enhanced phones, smart phones, palmtops, laptops.

 Multiple displays like Text only, Bitmapped.
 Multiple input devices-numeric keypads, touch screen, stylus.
 Multiple transports like 1-way SMS, 2-way SMS, Circuit Switched data, Packet data.
 Scalable applications like Applications are written once and run on all devices.
For available devices, the Wireless Application Protocol will be applicable, but not limited to
the following:
 GSM 900, GSM 1800, GSM 1900

 CDMA IS-95
 TDMA IS-136
