Bullpen Wireless FAQ

What is Spread Spectrum?
Radio Frequency Modulation Technique is a unique communication process created as an anti-jamming technique by the military. Spread Spectrum Techniques must be used in Industrial, Scientific, and Medical bands which are public and do not need FCC regulations to use. Major Benefits: Security, Interference Immunity and No FCC 5. Bullpen Wireless offers Frequency Hopping Technology as one of its solutions.

How does Spread Spectrum work?
As with other Radio Frequency data communications, Radio Frequency and Digital components have two modulation processes. In the first, data is applied to carrier frequency where the carrier is spread over entire bandwidth. Whereas, Spread Spectrum Data is spread over a band of multiple frequencies that occupies much greater bandwidth than the transmitted data actually needs. By minimizing power at any given frequency, Spread Spectrum has immunity from interference in the same band, as well, lower spectral power creates less density than narrowband, though, transmit power levels are similar. With this technology the Spectrum is Dynamic in it's efficiency.

What are the features of Spread Spectrum Security?

Security inherent to technology.
Low output power making detection extremely difficult.
Low power spectral density.
Direct Sequence - Chipping Code.
Frequency Hopping - max time on one frequency 5.3 ms per 1 second - hopping frequencies and sequence must be known .
Additional encryption and scrambling add-ons by radios used by Bullpen Wireless.


What are the features of Spread Spectrum Interference?

PCS, Pager, Cellular work in 800-900 MHz
Bullpen Wireless's radios work in 2.4 - 2.4835 GHz
Spread Spectrum designed to withstand interference with their low power spectral density and spreading of data over wide bandwidth.


Does the Atmosphere affect Spread Spectrum?
Spread Spectrum is not affected by fog, rain, sleet, or falling snow.

Are there any Line of Sight requirements?
For wireless bridging, yes, antenna line of sight is required. Trees and Buildings greatly reduce range and performance; therefore line of sight is highly desirable.
In regards to Indoor installations, line of sight is not required. However, walls and obstructions can reduce range.

Can I use this for building-to-building LAN and WAN bridging?
Yes - self-learning, Ethernet bridge, protocol independent

What are ISM License Free Bands?
ISM - Industrial, Scientific, Medical
FCC license free - Part 15 rules
1 Watt transmit power; 4W EIRP (Effective Radiated Power)
The frequency that Bullpen Wireless uses is 2.4 to 2.4835 GHz
