So the gateway are only for old dialup on mobile phones Not for modern gprs?
the normal Kannel WAP gateway provides the WAP 1.2.1 stack (including WAP Push), which uses UDP as IP bearer and can be utilized via CSD or GPRS. In fact the underlying radio transmission technology is not specified in the specs.
For WAP 2.0 you use "more or less" plain HTTP, with some addition of WTCP which uses a "radio-efficient" TCP implementation.
Essentially today, the WAP gateway takes 2 roles:a) transcode from WAP 1 phones the WTP/WSP layers to TCP for the target HTTP servers.
b) provisioning of RADIUS values in HTTP headers towards the target HTTP, i.e. for registered VASP or the MMSC of the operator to receive the MSISDN of the user.
The normal Kannel can handle both, where the Kannel-CG includes a full WAP 2.0 stack and a more complex RADIUS AAA framework. Both are relevant for mobile network operators, and don't make any sense for VASPs, as long as they are not in control of the GGSN of the network, "or" the MNO provides a dedicated APN via it's GGSN towards the VASP, i.e. for closed user base functionality.
