1. A mesh network comprising a plurality of nodes, each node comprising:
- a light source for emitting a modulated light to be received by a mobile device;
a radio-frequency transceiver for emitting and receiving a radio-frequency signal enabling bi-directional communication with at least one other node in the mesh network; and
a power supply for drawing power from an AC mains source and for supplying power to the light source and radio-frequency transceiver.

Abstract
A light source emits a modulated light, and a radio-frequency transceiver disposed therewith emits a radio-frequency signal. A mobile device may receive either or both signals and determine its position based thereon. The light and radio-frequency sources may be disposed in node in a network of said sources, and the nodes may communicate via the radio-frequency transceivers.

11. A method of communicating among a plurality of nodes in a mesh network, the method comprising:
-
emitting, from a light source disposed in each node, a modulated light to be received by a mobile device; emitting and receiving, from a radio-frequency transceiver disposed in each node, a radio-frequency signal to thereby enable bi-directional communication with at least one other node in the mesh network; and drawing power from an AC mains source and supplying power to the light source and radio-frequency source in each node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
