White Space Plus for Operators & Users

Spectrum Bridge’s vision is to empower the wireless Internet by improving the availability, access and allocation of wireless spectrum. In this pursuit, Spectrum Bridge has developed an FCC certified spectrum management platform to manage the White Space ecosystem. Spectrum Bridge offers two tiers of service designed to help you optimize the performance of your network:

White Space Plus: Spectrum Bridge’s White Space Plus service provides advanced features designed to help you optimize the performance of your unlicensed network. This service includes planning tools to facilitate better network design and ensures the best performance in daily operation.

White Space Basic: This service provides radio devices with direct access to the database and channel lists, ensures FCC compliant operations and is offered for the lifetime of the device.

The Advantages of White Space Plus

Optimize Network Performance

White Space channels available in a specific location will not necessarily provide equal performance (click here to learn more). Spectrum Bridge’s patent-pending Guided Channel Selection service will ensure that your devices select the best available channel and provide the highest possible performance. Channel lists are ranked and optimized by evaluating RF environment parameters, such as frequency, adjacent channel interference, proximity to protected services and noise floor.

Interference Mitigation

White Space devices are not offered exclusive access, which creates possible interference between devices operating in different networks with overlapping coverage. Spectrum Bridge’s White Space Plus service offers tools to help detect and overcome interference caused by overlapping use of channels.


White Space Plus tracks the channels used by White Space devices, and through the use of an Interactive Network Map, operators can observe which devices are using the same channels in areas with overlapping network coverage. Whenever overlapping channel use is detected, the operator can use the White Space Plus Preferred Channel feature to instruct devices to use a specified available channel to help eliminate or reduce interference.

White Space Plus Features

•Guided Channel Selection Service (including noise floor information)
•Interactive Network Map, displaying:
•Network Operator’s devices on map at installed location
•Device’s Coverage Radius (based on transmit power and user specified path loss model)
•Active Channel (currently being used by the device)
•Channels Available at device’s location, and Last Channel List sent to device
•Device Details (FCCID, Serial Number, Preferred Channel, Time before next channel request, etc.)
•Other Network Operator’s devices, shown on the map to help with co-existence planning

•Set Preferred Channel service to facilitate device channel selection
•Receive automatic notifications when a potential interference or channel conflict occurs
•Device Inventory – Showing Preferred Channel Settings and Active Channel per device

Selecting the best available White Space channels is essential.

Use Spectrum Bridge’s TV White Space Database Technology to ensure your White Space Network is optimized.

White Space is not really white, it is gray. TV Broadcasters do their very best to provide adequate coverage over large areas and this requires transmitters to generate very strong signals, sometimes in excess of a megawatt. Although protection is provided to TV receivers, this threshold (41 dbuV/6MHz for UHF channels) is approximately equivalent to -75 dbm/m^2, and similar to the signal strength needed for a broadband radio to operate at high data rates.



First, second or even third channel adjacent channel emissions from a TV transmitter can also impair broadband receivers, especially when operating in close proximity to a TV transmitter site.

For reference, a 6 dbi antenna employed at 600 MHz has an equivalent effective aperature of ~80 cm^2, and will result in an undesired signal of -85 dBm, in the presence of a TV signal field strength of 41 dbuV/m. This exceeds the threshold capable of impairing a TVBD receiver!

Fortunately these conditions are the exceptions, and the majority of available TV white space channels are capable of providing unimpaired use.

An example of this can be illustrated through actual measurements,

and be accurately predicted using Spectrum Bridge’s spectrum management technology.
