= Features/MoreMobileBroadband = https://fedoraproject.org/wiki/Features/MoreMobileBroadband Feature owner(s): Dan Williams <dcbw at redhat dot com> New mobile broadband devices supporting multiple technologies (eg, CDMA/EVDO/LTE and/or GSM/UMTS/LTE) and using new proprietary protocols are becoming common in the marketplace, and are not well supported by ModemManager 0.6 and earlier. We developed ModemManager 0.7/0.8 with a new API specifically to address this issue and to be more compatible with future mobile broadband devices. == Detailed description == Multi-mode Qualcomm-based devices have on the market since 2009 and support multiple WWAN technologies, often at the same time or with a runtime firmware change. CDMA-based carriers migrating to LTE (like Verizon, Sprint, China Telecom, KDDI, etc) require these multi-mode devices to ensure that coverage is not interrupted when handoff between CDMA/EVDO and LTE occurs. ModemManager 0.6's D-Bus API simply could not be extended to handle these cases, and due to this, the opportunity was taken to rewrite the API to ensure future functionality could be more easily supported in the D-Bus API. Additionally, most newer Qualcomm chipsets (which the majority of phones and data cards contain) use the proprietary QMI protocol for most operations instead of their limited AT command port. We have developed the libqmi library to support these devices, and ModemManager 0.7 and later use libqmi to provide fully-featured support for these Qualcomm devices. _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
