Wireless Spectrum Challenges and Issues
“The radio spectrum available for wireless data
services and systems is extremely scarce, while demand for these
service is growing at a rapid pace. Spectral efficiency is therefore of
primary concern in the design of future wireless data communications
systems.”
- Institute of Electrical & Electronics Engineers.
The
deployment of wireless communication systems is growing rapidly and
hence faces the following challenges and issues:
Interference
issues
- Interference
in unlicensed bands resulting from rapid growth in use of
technologies such as Wi-Fi and Bluetooth,
- Co-channel
interference in licensed bands as a result of poor frequency
planning,
- Adjacent
Channel Interference.
Spectrum
Management challenges
- Effective
frequency planning to reduce inefficiencies in spectrum utilization,
- Enforcing
a no-wireless policy in organizations.
Surveillance
challenges
- Preventing
unauthorized usage of spectrum,
- Detecting
and locating radio transmissions affecting law
enforcement and/or public security communication systems,
- Monitoring
and preventing inadvertent interference and malicious denial
of service attacks.
Wireless Signal Analysis Applications
ThinkRF’s
Wireless Signal Analyzers offer state-of- the-art signal
detection and analysis capabilities in a compact, lightweight, low
power, field-deployable form factor.
Un-manned
remote WSA analyzers can be distributed through-out a
location. Signal capture and pre-processing is performed by the
WSA's. Results are communicated to the centralized capture and
analysis server, thus enabling continuous, real-time capture of a
geographical space.
ThinkRF's
Multipoint Real-Time Signal Analysis provides an effective
solution to the following applications:
Signal
measurement and analysis over large geographic areas
- Detecting
spectrum occupancy
- Monitoring
and mapping spectrum use over both time and frequency
Automated
spectrum management
- Un-manned
remote operation
- User-defined
event triggers to capture burst signal transmissions
Signal
intelligence and spectrum surveillance
- Detecting
and tracking of moving transmitters
- Simultaneous
real-time surveillance of a large distributed area.
