To facilitate commercial roaming implementations between member operators, the WBA has developed WRIX (Wireless Roaming Intermediary eXchange), a modularized set of standard service specifications. The WRIX model facilitates wireless broadband service between visited network providers (VNPs) and home service providers (HSPs). The WBA WRIX was the winner of the Wireless Broadband Innovation 2007 award in the Best Wi-Fi Product / Service segment.
 |
No need for multiple VPN connections with different configuration |
|
No need for multiple and different RADIUS configuration |
|
Implement a standardized method for mediation of RADIUS Accounting to CDRs which can be rated |
|
Implement a standardized whole sale rating of mediated RADIUS Accounting CDRs, supporting all possible charging principles (Duration, Volume, session and/or a mixture of these) |
|
Implement a standardized method to make revenue assurance (SOX) |
WRIX-i (Interconnect)
The WBA WRIX-i specification in particular deals with the authentication, authorization and accounting (AAA) part of the interconnect.
WRIX- d & f (Data Clearing & Financial Settlement)
The WRIX- d & f specifications, in particular, deal with the data clearing and financial settlement between operators.
“Operators” shall exchange for feeds of partner service locations. This specification includes both the file format and file exchange method. It clearly describes the Mandatory verses Optional fields in the WBA Location database so that there is uniformity of information across all the WBA Members.
WISPr offers authentication services in a walled garden environment which is used predominantly by the WISPs for roaming. WISPr is a transport mechanism for authenticating protocols such as Radius, Diameter and the WBA WRIX specification. Among other things WISPr 2.0 extends the non-802.1x network capability to perform EAP authentication and also fixes many of issues related to roaming in WISPr 1.0
|
Reduce the inter-operability problems of WISPR 1.0 through strict rules on known problems |
|
Facilitates seamless authentication by being a transport medium for the EAP packets |
|
Provides support for session state query |
|
Provides support for shared WiFi infrastructure for e.g Airports where WLAN infrastructure is shared between different hotspots network providers |
| The white paper on “The Road to Enhancing the Public Wi-Fi Access Experience” is the result of a FMCA & WBA supported trial to demonstrate the seamless roaming and authentication between GSM and Wi-Fi networks using a IEEE 802.1x network. The paper describes the trial objectives, an overview of the trial, publishes the trial results and finally describes the opportunities that exist post trial. This whitepaper draws on the learning from joint WBA-FMCA trial in which 16 operators and 3 roaming hub vendors took part. |
