The NBLR modem solution, developed by Tata Elxsi (TE) is based on the Mobile WiMAX standard (802.16e-2005).i TE enhanced the standard to meet the wide area, IP data needs of mission critical industries. This included adapting the PHY and MAC layers to support VHF and UHF frequencies for non-line of sight, long-range communication.
The NBLR modem is a turnkey, end-to-end solution which includes the base station, the mobile and fixed station radios and the network management system and configuration tool.
This solution enables the operator to establish mobile and fixed data coverage up to 20 miles from a base station tower site. We achieved this improved coverage through a series of enhancements to the WiMAX-e standard including:
A Wide Range Software Definable Radio which supports all frequencies from 40 MHz to 958 MHz.
Narrow Channel Support: The WiMAX PHY was enhanced to operate in narrower channel sizes (starting as narrow as 200 kHz in width).Narrow Channels are easier to adapt from the unused spectrum bands with low cost of acquisition.
High Tx Power: The transmit power is adjustable from 4- 10 watt using suitable heights of antenna, matching various needs based on terrains and utility requirements.
The modem is targeted at the following industries and possible areas of application as below:
- Public Safety & Emergency Services
- Power Transmission and Distribution
- Natural Gas Production, Transmission and Distribution Companies
- Water and Wastewater Industries
- Oil Exploration and Extraction Companies
- Large construction and engineering Sites (bridges, railroads, dams, airports)
- Pipeline Transportation
