Teko Master Unit

 

Architecture

 
The modular sub-rack allows adaptation of deployment needs including the addition of newer technologies within sub-racks that prepares venues to be more adaptive to venue needs (e.g. new sectors) and to introduce newer services into the existing venues DAS system. The Master Units DAS shelf and architectural design minimizes system footprint, saving 30-70% of critical space requirements within venues, BTS Hotels, Co-location environments. The Teko system design allows for passive repeater or active / optical DAS configurations and the system can be reconfigured as needs change.
 

Installation & Commissioning

The Teko supervisory intelligence provides automated identity of the deployed system elements, including identity all of the modules installed within Master Unit sub racks and Remote Units. The result is a typical system in a venue can be discovered within a couple minutes, allowing engineers to move more swiftly through the commissioning process.  The Automatic Gain Control (AGC) with Optical loss compensation providing up to 10dB of Optical Link Budget automatically measures and calibrates for link losses to Remote Units without the need for additional equipment and manual measurement within a venue. Teko’s remote administration and spectral assessment tools using the Teko Multiband Spectrum Analyzer empower engineers to quickly commission and optimize a venue.

Advanced Administration

 
The Teko Supervision module provides web-based administration and SNMP v3 support with Event-based Configurations that significantly simplify remote administration (web browser, tablets) and enables integration with SNMP v3 Management tools.
 

Single Fiber Cable Infrastructure

 
The Teko platform utilizes single fiber connectivity to each Remote Unit utilizing WDM or optional DWDM. Leveraging single fibers reduces installation costs by at least 50% (fiber strands, splicing, leasing, etc.) and the Single fiber approach eliminates errors in UL/DL fiber inversion.
 
 

Flexible and Intelligent Signal Sourcing

 
The High-power POI DAS Tray utilizes a small footprint for Base Station to DAS Master Units utilizing a common sub-rack can reduce space requirements vs. passive trays as much as 75%. Managed as a single system it enables remote optimization of the site parameters, provides alarming for base station failures.

The active POI provides automatic power limiting with alerts automatically monitoring operator input power and attenuating (w/ alarms) to maintain RF coverage and balance across multiple POI inputs.
 

Point-to-Point WDM / DWDM

 
Allows multi-band services to be delivered across distributed venues (up to 12 miles apart), managed, as a single system while optimizing fiber needs.
 

Multi-class Optical Transceivers

 
Multiple power classes for up to 6 bands can be combined in a single transceiver, including 31, 36, 40, 43, and 46 dBm per frequency band.
 

Excellent Signal Quality Handling

 
Peak-to-Average amplifier ratio of 9dB for High Power and 12dB for Low Power for high capacity modulation maintains excellent EVM performance and high-throughput to ensure LTE & UMTS performance and sector utilization efficiency.  High isolation output combiners assure negligible IMD levels and lower interference and noise in UL bands for multi-operator scenarios, increasing data throughput and assisting in markets with UL frequency sub-bands. High linearity power amplifiers using an in-house feed-forward and DPD amplifier design are critical to maximizing DAS performance and minimizes amplifier footprint while providing best-in-class digital pre-distortion (DPD) and allows control of minimizing IMD.
 

Multiband Spectrum Analyzer

 
Remote spectrum analysis or recording for noise levels, interference, PIM analysis, etc. for up to 5 bands on single port enables field teams to remotely analyze performance or initiate recording to capture system performance. Can be applied without the need to add couplers for each RF path.
