Improve productivity
A business can use a WAP gateway to provide a secure connection to its corporate network, improving internal communication flow by making information available to mobile as well as office users.
White Paper Z600
The Z600 has dynamic WAP profile handling, which means that the user can add, edit and delete WAP profiles. There are up to 5 WAP profiles.
During WAP browsing, the options button gives the user immediate access to a dynamic option menu for WAP services, similar to a mouse
The WAP profiles
A WAP profile holds network settings and user identification, allowing the user to switch easily between corporate services and WAP services on the Internet, simply by switching WAP profile.
Bearer type characteristics
The Z600 accesses WAP services over IP. IP can be provided either over GSM Data, HSCSD or GPRS, depending on network services.
Typical differences which distinguish the bearer types are listed below.
High Speed Data
Higher transmission speed than with GSM Data or SMS access.
Pricing of GPRS can be dependent on the actual use of bandwidth, which means the user is charged for the volume of data transmitted, rather than the duration of the connection.
High Speed Data (HSCSD) increases speeds for circuit switched data by allowing the phone to use a coding scheme with a high capacity, and to use two time slots for receiving data. The download speed is increased to up to 28,800 bps. The speed for sending data is limited to 14,400 bps. The data rate can be increased several times by the use of rate adaption, interworking with ISDN. This also provides additional features, such as quick call set- up capability.
GPRS access
The connection is maintained “constantly”, with data transmitted in packets, and transmission capacity being used by the application in use on an
When transmitting large amounts of data, band- width can be increased automatically to allow faster transmission speed.
Ideal for complex pull services, browsing, data transfer, provisioning, pager services, messaging services, info services, push initiations.
GSM data access
Circuit connection of data calls, which means that the phone is connected during the entire WAP ses- sion.
Pricing is comparable to that of data calls in the network.
Gateway characteristics
A WAP Gateway provides Internet/intranet as well as WAP services to the mobile browser. A Gateway is identified by an IP number, depending on access type.
