Definitions

  • the present invention relates to a power socket adapter, and more specifically to a power socket adapter having additional functionality.
  • FIG. 1 there is illustrated schematically a known Devolo ® MicroLink dLAN Ethernet high speed 85Mbps Ethernet over mains adapter.
  • the adapter comprises a housing 100 which contains an electronic circuit board having a power mains to Ethernet conversion chip for applying digital communications signals input via an Ethernet socket 101 to a mains power ring main, via a plurality of electrical contract pins 102 which plug into a conventional mains wall socket outlet.
  • Various versions of the known adapter are available, with Ethernet speeds of up to 200Mbps.
  • the Devolo dLAN product is capable of running a small network in a domestic or commercial premises, and connecting that network over the existing mains ring wiring, without the need to install an additional local area network cabling, for example, an additional CAT5 wiring system.
  • the existing dLAN adapter product has a disadvantage of only permitting one wired Ethernet socket per mains outlet socket. Further, using the known adapter device means that the power socket is used for that device, and is therefore unavailable for use by other devices such as PCs, printers, scanners or the like.
  • FIG. 2 shows another known adapter 200 which not only provides a socket 202 into which the plug of an appliance may be inserted, but also includes a sensor 204 which in this case is an infra-red sensor for detecting human movement, such as a PIR sensor.
  • a sensor 204 which in this case is an infra-red sensor for detecting human movement, such as a PIR sensor.
  • additional functionality can be provided by allowing for the power supply to the socket 8 to be activated or de-activated internally of the adapter, for example when human motion is detected in front of the sensor 204.
  • the electronics inside the adapter (not shown, but of entirely known configuration) is not only powered by the mains supply derived from the connection between the adapter plug portion shown generally at 206 and the wall or other power socket (not shown) into which it is inserted, but said electronics also provides an automatic switch function for the adapter.
  • such an adapter may be controlled by a handheld battery powered remote control device so that the power socket can be turned on and off, without the need for a user to stand up and walk to a power socket.
  • lntellon Corporation of the USA has established itself as one of the main suppliers of products facilitating the provision of such communications networks internally of domestic, commercial, office and other spaces through their power cabling loops.
  • one of the fundamental difficulties perceived by the inventors herefor is that the use of lntellons 1 equipment necessarily utilises at least one of the sockets of a conventional socket wall plate, and in most cases, and particularly in the case of computer equipment to which an Ethernet connection will usually nowadays always be required, many power supplies are required.
  • this has resulted in the dangerous overloading of wall sockets by using many one to many electrical socket devices or extension cables to provide power sources for various devices, such as monitors, printers, modems, and computer base units.
  • FIG. 3 there is illustrated schematically a further known LAN to mains adapter 300, produced by DS2.
  • the DS2 Power Line adapter enables a consumer installed networking at home or in the office and has a built in power socket which frees up the wall outlet socket to which the DS2 adapter is connected, for use by other appliances, by virtue of its "plug through” feature, having a power socket on its externally presented face, in addition to an Ethernet LAN socket.
  • the lntellion LAN-mains adapter 300 is provided with one or a plurality of light emitting diodes, which flash, to inform the user that the device is working correctly.
  • FIG 4 an installation of the known LAN-mains adapters of figure 3 is illustrated schematically.
  • a one to many mains extension socket 402 can be used as a power socket plug for many peripheral devices, such as a PC 403, a printer 404, or a DSL modem 405.
  • the Ethernet cable of the modem 405, plugs into the Ethernet socket of the known power line adapter 400.
  • Digital communication signals are passed from the peripheral devices, from the DSL modem 405 and through the adapter 400 into a mains electrical cabling 406, and the signal can be "tapped” at any other mains socket outlet 407, 408 on the same mains electrical cabling network.
  • mains wiring based communication networks are becoming more common for home networking or networking of commercial premises, there remains a set of ongoing technical problems including the following.
  • Modern portable devices such as laptop computers, PDAs, mobile telephones, and consumer appliances increasingly make use of a wide variety of wireless technologies, which are not accommodated by the known network to mains adapters.
  • Plug congestion at a mains power socket remains a problem, with mains power peripheral devices, such as PCs, scanners, battery charges, monitors and printers, each requiring a separate mains socket adding a plug in network to mains adapter adds to the congestion around known power socket outlets.
  • mains power peripheral devices such as PCs, scanners, battery charges, monitors and printers
  • connection to a wide area network of the internet is generally over a lower capacity link, such as a broadband link or coaxial cable which means that the high data rate applies only internally on a local network and cannot easily be extended to a wide area network.

Consequently, the Wi Fi device can automatically vary its level of signal to an optimum signal intensity, at which communication with the power line socket can be achieved with sufficient signal to noise ratio, and yet the power intensity of the5 signal transmitted and received is reduced to a minimum level, in order to avoid unnecessarily high levels of electromagnetic radiation.
  • Wi Fi enabled power line sockets there are in a given room the greater the selection of Wi Fi enabled power line sockets there are to choose from in a room, and therefore the more likely it is that a relatively lower power intensity level of Wi - Fi connection o can be made, compared to the situation where there is one Wi - Fi transceiver in a room.
