Method of radio communication between columns of a lift and associated lift

A radio communication method between a plurality of columns, the method comprising the steps of:

• providing said plurality of columns in communication by a multichannel mode comprised of a plurality radio channels, each column being cooperative with at least one other column so as to form a bridge, each column having an operating mode selected from a group consisting of a lifting mode and a stop mode, wherein each column has a respective operating mode selected in a predetermined frequency band of said plurality of radio channels;
• powering on each column;
• scanning transmissions of said radio channels by each column so as to detect available channels, occupied channels, and scrambled channels;
• selecting a first column for said bridge by assignment of an entry key by an operator;
• selecting a free channel selected from said available channels;
• forming a beacon channel with said free channel, said operator managing said beacon channel to register at least one other column, said at least one other column having said entry key, said beacon channel broadcasting to said plurality of columns;
• registering said first column, said at least one other column N, and any other columns having said entry key so as to determine bridge columns corresponding to said bridge;
• closing the step of registering, said beacon channel forming an operational channel for said bridge columns;
• dialoging between each bridge column on said operational channel so as to synchronize respective operating modes of said bridge columns;
• and
• forming said bridge,
• wherein said first column, said at least one other column, and said any other columns having said entry key being registered in time slots chronologically,
• wherein any bridge column initiates the step of closing the step of registering, and
• wherein any bridge column sets the operating modes of said bridge columns during the step of forming said bridge;
• and
• installing an open systems interconnection protocol being comprised of a physical layer as a layer 1, a data link layer as a layer 2, a network layer as a layer 3, a transport layer as a layer 4, a session layer as a layer 5, a presentation layer as a layer 6, and an application layer as a layer 7, wherein said transport layer, said session layer, and said presentation layer are grouped together in a single presentation layer between said network layer and said application layer, said single presentation layer shaping data for the steps of scanning transmissions, selecting said first column, selecting said free channel, forming said beacon channel, registering said first column, closing the step of registering, dialoguing between each bridge column, and forming said bridge.
