Dynamic Spectrum / White Spaces

using coverage calculations and subscribers, ICS telecom EV determines where White Spaces may be added and the impact White Space devices may have on existing licensed users, such as broadcasting and wireless microphone users.

Decades of experience in signal propagation and coexistence means that ICS telecom EV offers a comprehensive set features focused on White Space:

  • DTT coverage
  • Reserved channels
  • Allotments, assignments, PSME, international coordination & protected areas (polygons)
  • DTT white-space calculations
  • TVWS availability calculations
  • Produces spectrum maps
  • WSD channel assignments
  • WSD to DTT interference calculations
  • Data storage: Location / channel / WSD class / permitted power level / online access

ICS telecom EV features a wide set of multi-technology oriented functions to exploit potential applications in white spaces:

  • Devices or routers vs licensed service areas (C/I mode)
  • Licensed services vs devices or routers (IRF and C/I modes)
  • Licensed services vs earth satellite Rx (GSO, NGSO, Constellations)
  • Devices vs devices or routers vs routers or devices vs routers
    (IRF mode)
  • Devices or routers vs polygons or routes (PFD)
Enhanced Wi-Fi

Challenge

The majority of current WiFi devices operate in the 2.4GHz spectrum band. White Space could provide additional capacity and boost the distance a device (WSD) can be from a base station and remain connected. This enables WiFi networks to stretch across towns and cities, as a result of the lower frequency of TV white space (typically between 470 and 790 MHz).

Solution

The main difference between WSD and WiFi is the white space router needs to consult an online database (WSDB), notify its location and update this on a regular basis. The database then returns details of the radio frequencies and power levels the router can use. This ensures that the connected devices do not interfere with existing spectrum usage.

Using ICS telecom EV, a WSD operator can identify white spaces and potential interferes in a specific area to complete the white space workflow and publish the data online.

Machine-to-Machine Communications (M2M)

Challenge

Machine-to-machine communications allow information to be exchanged between devices. White space could be used to transmit this information wirelessly, using its additional range to reach deep inside buildings. This could be particularly useful for wireless utility meters in consumers’ homes, keeping an inventory of stock owned by a business or making it easier for scientists to conduct research by automating the measurement of different readings.

Solution

Due to the complexity and the wide range of M2M applications, ATDI has a dedicated a team of experts to support  the planner at every stage of the project ranging from:

Guidelines
Vendor references
Planning
IT integration
System inter-connectivity
Frequency resources
Web services
Tests
Embedded Sim and module analysis
Roaming.

ICS telecom EV supports the white space which could be used.

ATDI: Infinite connections

Rural broadband

Challenge

White space could be used to provide rural locations with broadband services. In practice, this could be achieved by building a network of transmitters that use white space to link remote houses and villages to larger towns, that are already connected to the internet.

Solution

Coverage calculations and P2P analysis using subscribers in ICS telecom EV identify areas where broadcast or other systems offer no coverage on a specific channel, that can be reused to provide broadband access.
