Proteus® with PurePass®
Proteus® is a digital signal processor conditioning the cellular receive uplink RF path. This produces an RF signal free of unwanted co-channel interference and adjacent RF power. Proteus® with PurePass® RF digital signal processing helps operators ensure the cleanest signal, limited to the desired bandwidth, is passed to the base station even in the most difficult environments.
Each unit is now configurable for 4G as well as 3G protocols.
Proteus® Features
Adaptive Interference Mitigation ("AIM") eliminates the corruption caused by narrow band co-channel interference, passing an RF signal free of unwanted in-band interference
- Reduces noise rise
- Removes GSM and other rapidly occurring, highly dynamic interferers
- Recovers coverage, capacity and performance
User Defined Band Rejection activates software-defined band-reject filters through a simple user interface
- Through PurePass® digital signal processing, a specified bandwidth is substantially removed to minimize the effects of the desired carriers
- User chooses center frequency and bandwidth of band-reject filters
- Adds extra isolation and selectivity improving adjacent channel selectivity
Carrier Select Conditioning isolates the desired carriers and passes them to the base station, while greatly reducing adjacent channel power at the receiver/radio
- Improves adjacent channel selectivity
- Protects carriers from adjacent channel signals
- Minimizes unnecessary power entering the band
- Change frequency bands as needed
- Enhanced band-pass filter capabilities
ProView® and SpectrumView® Plus analysis tools provide visibility into the condition of the spectrum and log interference activity.
With growing demand for speed and capacity due to increasing data traffic, call volumes and complexity of calls, most wireless carriers are hitting the limits of their allotted 3G spectrum and are deploying new 4G networks. Proteus® maximizes spectrum utilization by using PurePass® RF digital signal processing to ensure full use of existing carriers, permit more carriers and, ultimately, enable more calls and data throughput.
Proteus® applications:
- Support more carriers in existing spectrum —
Immediately increase capacity - Reduce interference from random sources —
Protect and condition carriers - Optimize performance at special events —
Maximize capacity and protect quality of carriers - Improve coverage and capacity in coastal and dense urban areas —
Complete more calls - Mitigate cross-border, GSM and rapidly occurring, highly dynamic interference —
Eliminate spectrum intrusions, maintaining maximum network performance
