Definitions

  • the invention relates to the technical field of wireless communication systems, partic- ularly to devices for and methods of extending and enhancing coverage of long-range wireless communication systems.
  • Mobile phone users often experience poor coverage from cellular networks both indoors (e.g., in houses, offices, warehouses, etc.) and outdoors (e.g., in so-called urban canyons), for example in terms of disconnections or low data rates.
  • indoors e.g., in houses, offices, warehouses, etc.
  • outdoors e.g., in so-called urban canyons
  • a solution to this problem is either to install a cellular base station or a repeater in an area of poor coverage.
  • a repeater may amplify and forward the signal received from a cellular base station.
  • the latter solutions do not provide optimal coverage due to the fact that the technologies employed in cellular systems have not been designed for indoor propagation conditions.
  • the employment of said solutions would imply a larger and more costly infrastructure to be managed by the mobile operator, due to the installation and maintenance of relatively complex base stations or repeaters.
  • only mobile op- erators which have bought a license for cellular frequencies, are allowed to install base stations or repeaters and use them within the same frequency band.
  • a first aspect of the invention is to provide an improvement to the state-of-the-art.
  • a second aspect of the invention is to solve the aforementioned drawbacks of the prior art by providing a solution that extends and enhances coverage of long-range wireless communication systems both indoors and outdoors.
  • a third aspect is to solve drawbacks in signal reception due to local obstacles.
  • a fourth aspect is to solve communications issues during critical or emergency situations in areas with extended wireless coverage.
  • a device for extending and enhancing coverage of a long-range wireless communication system (e.g., a cellular system), wherein the device comprises a first wireless communication means (e.g., a physical or a logical SIM card, a transceiver and an antenna) based on a long-range wireless communication standard (e.g., GSM, UMTS, LTE, WiMAX, etc.) and a second wireless communication means (e.g., a transceiver and an antenna) based on a short-range wireless communication standard (e.g., WiFi, Bluetooth, ZigBee, etc.), said first and second wireless communication means being operable to transmit and receive data wirelessly in a long range and a short range, respectively, wherein, when data (e.g., associated to a GSM call, an SMS, an MMS, a video call, etc.) intended to a

  • a GSM base station may have a coverage of up to 80 km and a WiFi access point of up to 100 m indoors and 200 m outdoors.
  • the antennas of the first and second wireless communication means may be co-located with the device or located at a distance from the device.
  • the antennas may be placed so as to obtain the best signal reception (e.g., on the roof of a building or a car) while the device may be placed where it is more convenient for the user (e.g., in a closet or in the trunk of a car).

  • the device needs not to establish new connections but may continue to use the already established connections.

  • the invention besides establishing a gateway between two or more wireless communication standards, has the advantage of virtually enhancing the coverage of the long-range wireless communication system by providing better signal reception within the same area. Also, the invention has the advantage of virtually extending the coverage of the long-range wireless communication system thanks to the physical transmission range of the second wireless communication means of the device. This is, for example, advantageous when the recipient is in fact outside coverage of the long-range wireless communication system but inside coverage of the device, since data intended to the recipient will anyhow reach it by being routed via the device.
