Proxim ClearConnect™ is a suite of advanced interference mitigation technologies designed to ensure resilient and dependable communications in high-density wireless deployments. It leverages continuous analysis and automated link tuning to consistently deliver optimal performance.
Dynamic Data Rate Selection (DDRS)
DDRS facilitates the adaptive adjustment of wireless traffic data rates. Especially crucial in point-to-multipoint networks where Clients vary in their support for different data rates due to varying distances from the Base Station Unit (BSU). WORP® utilizes DDRS to dynamically optimize data rates for individual Clients, thereby maximizing the overall net throughput.
Flexible Channel Size Support
Flexible Center Frequency
This feature enables the precise configuration of the operating channel center frequency in 1 MHz increments. It ensures that the radio link utilizes the cleanest spectrum available for improved performance.
Satellite Density
Satellite Density settings enhance bandwidth utilization in wireless networks by adjusting receiver sensitivity, particularly beneficial in high-noise environments. Lowering device sensitivity helps filter out unwanted "noise."
Automatic Channel Selection (ACS)
ACS serves as an essential installation tool, allowing Proxim radios to autonomously choose the most suitable channel with minimal interference during network boot-up.
Dynamic Channel Selection (DCS)
DCS continuously monitors packet retry percentages within a radio link. If retries surpass a set threshold, it dynamically searches for a new channel with reduced interference.
Adaptive Transmit Power Control (ATPC)
ATPC dynamically adjusts transmit power for each Subscriber Unit (SU) to achieve the desired link signal-to-noise ratio without excessive power or interference. It ensures compliance with local Equivalent Isotropic Radiated Power (EIRP) regulations.
Short Range Optimization (SRO)
SRO, utilized for establishing concise links under 50 meters (150 feet), optimizes radio output power to prevent overload and instability, complementing ATPC for enhanced performance in short-range links.
Hybrid Automatic Retransmission Request (HARQ)
Proxim radios employ Hybrid ARQ, combining link layer Forward Error Correction and Automatic Retransmission Request (ARQ) mechanisms. This optimized approach selectively retransmits only damaged packets, improving duty cycle utilization and reducing latency in latency-sensitive traffic.
Weak Subscriber Mitigation (WSM)
WSM applies a "Minimum SNR Offset" filter, allowing subscriber association with the base station only when the signal-to-noise ratio (SNR) exceeds a defined threshold. It prevents excessive retransmissions from weak subscribers, preserving overall sector performance in multipoint sectors.
Spectrum Analyzer
Proxim's Point-to-Point and Point-to-Multipoint products feature an integrated Spectrum Analyzer. This tool provides real-time graphical representations of radiation or RF interference conditions in the available band, enabling manual selection of the best channel for optimal link operation.
