The GSMA is an association of mobile operators worldwide. Representing more than 800 mobile operators in more than 220 countries, the GSMA supports the standardizing, deployment and promotion of the GSM mobile telephone system. The GSMA also produces industry-leading events such as the Mobile World Congress and Mobile Asia Expo.
The GSMA OneAPI is a set of APIs that expose network capabilities over HTTP. The OneAPI Zonal Presence interface allows a Web application to query a â€˜Zoneâ€™. A zone is a cluster of one or more Femtocells to which end user phones may be connected. With the Zonal Presence API you can determine the number of users in a zone, be notified of entries to/exits from the Zone, and the user path taken through the Femtocells in a Zone.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
