These principles also turn out to make the protocol ideal of the emerging \u201cmachine-to-machine\u201d (M2M) or \u201cInternet of Things\u201d world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.<\/p><\/blockquote>\n<p>via <a href=\"http:\/\/mqtt.org\/faq\">FAQ &#8211; Frequently Asked Questions | MQTT: MQ Telemetry Transport<\/a>.<\/p>\n<p>I see RIM phones using this.<\/p>\n<dl>\n<dt><strong>Are there standard ports for MQTT to use?<\/strong><\/dt>\n<dd>\n<blockquote><p>Yes.
