Technical proposal invited for 28 SHF/ EHF MMTs for Wireless Monitoring Organization by DoT

The Department of Telecommunications has invited a proposal to procure twenty-eight numbers of fully integrated SHF/EHF Mobile Monitoring Terminals, ITU compliant Spectrum Monitoring System, covering the frequency band 1-80 GHz for all 28 Wireless Monitoring Stations of Wireless Monitoring Organization.

The overall system sensitivity shall be provided in dBW/m2 /4kHz. tput derived from the setup is sought. Bidders are invited to indicate the estimated/budgetary cost (inclusive of duties/taxes, freight charges, insurance etc.) for each SHF/EHF MMT including warranty of 3years, CAMC for five and the cost of installation & commissioning of the SHF/EHF MMTs including training to the officers. The detailed item-wise bleak-up and methodology of arrival at the estimated/budgetary cost for each SHF/EHF MMT (including cost breakup for CAMC, installation, commissioning, training, duties/taxes, freight charges, insurance etc ) is mandatory.

Brief Details of the requirements of the system :
The SHF/EHF MMTs is envisaged to be state-of-the-act, easy to operate, rugged, automated system housed in a suitably designed small/medium utility vehicle to meet the spectrum monitoring objectives in the frequency band 1-80 GHz.

The SHF /EHF MMT shall be designed & developed based on modular structure, which will provide flexible and upgradable configuration. This modular setup should be configurable to meet the system requirements and any subsequent expansions/updates should be easily implementable, by adding modules and software / upgrades etc.

Portable /handheld analyses/receiver (covering the frequency band 1-80 GHz) along with light weight antenna and telescopic mast to supplement the SHF/EHF MM”I’ for carrying out monitoring on the rooftop and in inaccessible areas.

Each SHF/EHF Mobile Monitoring Terminal JMMT) shall be equipped with the following supplies /deliverables:
Antennas and its assembly covering the frequency range 1-80 GHz with suitable Antenna switching unit, Antennas mount, Pedestal Rotator, Antenna Positioner, Retractable Mast for antennas (10 m above ground).

Low Noise Amplifier (LNAs) with appropriate gain and low Noise Figure QF).

Spectrum Analyses/Signal Analyser/Receiver, Programmable step attenuator, high quality Pie-amplifier, low loss RF cables, connectors, accessories etc., Equipment Rack Assembly, GPS Receiver & Electronic Compass.

Spectrum Monitoring Software, Modulation Recognition Software, Automation and control software, Graphical User Interface, OS, Drivers and Database Software etc.

Signal recorder with play back facility and external data storage.

Computer with display and laptop etc.

Power supply system, UPS and Low Noise and Compact power generator.

Handheld /portab1e Spectrum Analyzer with Antennas, tripod for mounting antennas and retractable & foldable mast.

Any other system which may be necessary for proper functioning of this EHF/SHF 5JMT system like riggers, compressors, Air conditioning system etc.

Suitably designed small/medium utility vehicle to install/house this system.

Measurement Capabilities:
The SHF /EHF MMT shall perform measurement/monitoring function in the frequency 1-80GHz such as Frequency, Bandwidth, PFD /PSD, Channel power measurement, ACPR, Occupancy/Vacancy etc in accordance to the applicable ITS’ Recommendations/ Reports.

The SHF/EHF-MM”1 should also have the following monitoring function and measurement capabilities while monitoring over-the-air RF emissions / transmissions in the frequency 1-80GHz:
– Standard Demodulation / Emission Identification such as FSK, BPSK, QPSK, QAM etc;
– Analysis and Identifica0on of Standard Transmission / Emissions of different technologies used in terrestrial and satellite communication.
– Spectrum measurements, I/Q, E4″M, Water fall display etc.
– Direction finding with integrated GPS and Map for Emitted/Transmitter marking & Homing.
– Data Streaming & Report Generation.
– System automation for determining course of actions when signal of interest is detected;
– Recording of the spectra, Data logging, storage and Management;
– Database for archival and retrieval of information, Data mining and information analysis,

Handheld SHF/EHF Signal Analyzer covering the frequency range 1 to 80 GH2 for detection, analysis and measurement of Low power wireless emissions /usages; versatile measurement functions and display functions; recording & play back internal DC Bias, Battery, GPS receiver etc. It should be rugged and all-weather use.

Bids are awaited by the DoT. The deadline for submission of the bid is November 22, 2021. CT Bureau
