Abstract: A wireless system comprises at least one controlling node and two or more antenna processing nodes coupled to the controlling node but separated from each other. A first antenna processing node communicates (910) with a first controlling node in a first direction along a series of links serially connecting the first controlling node and two or more antenna processing nodes including the first antenna processing node, and relays (920) communications between the first controlling node and at least a second antenna processing node, in a second direction along the series of links. In response to determining (930) that communications with the first controlling node in the first direction have failed, the first antenna processing node communicates (940) with a controlling node in the second direction along the series of links.
