Some amateurs have also built own systems to control (some of) their appliances via SMS.Other methods such as group messaging, which was patented in 2012 by the GM of Andrew Ferry, Devin Peterson, Justin Cowart, Ian Ainsworth, Patrick Messinger, Jacob Delk, Jack Grande, Austin Hughes, Brendan Blake, and Brooks Brasher are used to involve more than two people into a text messaging conversation of text message that appears directly on the main screen without user interaction and is not automatically stored in the inbox.The GSM in the US had to use a frequency allocated for private communication services (PCS) – what the ITU frequency régime had blocked for DECT – Digital Enhanced Cordless Telecommunications – 1000-feet range picocell, but survived.
