Claim of US Patent No. 10,973,108

1. A lamp configured to perform a method for optimizing an area coverage of a wireless network, the method comprising:computing locations having a predetermined field strength for all network access points with reference to a predetermined reference area,
computing whether there are locations on the reference area at which the predetermined field strength is not reached,
if so, increasing the transmission power of a network access point close to the location, repeating computing whether there are locations on the reference area at which the predetermined field strength is not reached and increasing the transmission power of a network access point close to the location until at least the predetermined field strength prevails at all locations,
computing whether there are locations with reducible field strength on the reference area,
if so, reducing the transmission power of the network access point that can be reduced to the greatest extent, repeating computing whether there are locations with reducible field strength on the reference area and reducing the transmission power of the network access point that can be reduced to the greatest extent until there are no further reducible network access points,
checking whether there are as yet uncomputed network access points,
if so, computing an as yet uncomputed network access point, and repeating computing the as yet uncomputed network access point until all network access points have been computed:
the lamp comprising:
an input for connecting the wireless network having an integrated power supply, wherein
the input is Power over Ethernet (POE) compatible, and wherein the PoE compatible input comprises at least electrical power for powering at least one light source and network data for forwarding to an access point via the PoE;
a power supply unit for supplying all components of the lamp with an electric power taken from the PoE compatible input, wherein the power supply unit is configured to isolate the at least electrical power from the network data, and wherein
the power supply unit is configured to provide the electrical power to the at least one light source;
at least one light source configured to receive the electrical power from the power supply unit,
a network access point for providing at least one wireless network, which network access point is configured to receive at least the isolated network data from the power supply unit and coupled to the network via the PoE compatible input, at least one antenna associated with the network access point, wherein
the light source and the at least one antenna are arranged and designed such that a radiation characteristics of the light source are congruent with a radiation characteristics of the at least one antenna of the wireless network referenced to one or more reference areas; wherein
the computing whether there are locations on the reference area at which the predetermined field strength is not reached is based on the congruence between the radiation characteristics of the light source and the radiation characteristics of the at least one antenna.
