Sheetal Wireless Technologies Pvt Ltd (SWTPL), an ISO 9001: 2008 company, is operational in the field of Wireless Communication for the past twenty two years. The company provides trusted wireless solutions for voice, data, video and remote control of factory cranes.  It has maintained a well planned course of horizontal expansion and growth over the years.

SWTPL provides total solutions for wireless communication systems including Analogue/Digital Data Radios, Wi-Fi Radios, GSM/GPRS Modems for SMS based communication and GPRS based data transfer, VSAT systems, Radio Remote Controls for industrial EOT cranes and Wireless Gateways, etc. 

SWTPL has been implementing various mission critical projects in industrial automation field and SCADA and Telemetry field pan India as well as overseas. The company puts emphasis on providing customised solutions rather than just distributing the products.

One of the successful cases of the company’s solutions providing capability is the industrial GPRS based solution for CNG pipeline network of GAIL India Ltd.

Project requirement

To collect data from pan India based CNG pipeline network to central SCADA system.


  • Live data monitoring of pan India based 700+ remote locations with two redundant central SCADA systems located 400+ km away

  • To achieve secure and reliable communication system with redundancy from both ends (Remote and central location) with use of different ISPs at different locations, and

  • To communicate with various types of RTUs/Flow meters/IEDs/Gas Chromatographs/Gas, Moisture Analysers having different type of protocols and interfaces.


To achieve this SWTPL used Inhand Intelligent GPRS Gateways connected to field devices (RTUs/Flow meters/IEDs/Gas Chromatographs/Gas, Moisture Analysers), which communicate with SWTPL Network Managers located at SCADA centres.


More than 95% availability with use of GPRS enabled SIM cards at remote locations.

Applications: electric utility, water utility, oil and gas, wind and solar energy, etc.


SWTPL provides consultancy and undertake turnkey projects   to provide trusted solutions in wireless voice, data and video communication. This includes:

  • Execute of RF feasibility surveys
