Abstract: Examples of the disclosure relate to position determination using one or more reflectors. In examples of the disclosure an apparatus can be configured to transmit information relating to one or more reflectors within a scattering environment to a network apparatus. The information relating to the one or more reflectors can be used by the network apparatus to enable signals reflected from the one or more reflectors to be used for a position determination.

Abstract: A light source includes a first light emitting diode (LED) die configured to emit a first die color and a second LED die configured to emit a second die color, the first and second LED dies provided on a substrate. A first filling covering the first LED die, and includes a first phosphor to convert the first die color to a first illuminous color. A second filling covering the second LED die and extending to the first filling, and includes a second phosphor to convert the second die color to a second illuminous color that has a higher absorption energy than an illumination energy of the first illuminous color.
