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
