Lekha has complete portfolio of 802.16e or Mobile WiMAX compliant software stacks for building both Mobile Station (MS) and Base station (BS) over an SDR platform. The list of software stack includes
- MAC layer for BS
- PHY Layer for BS
- MAC Layer for MS
- PHY Layer for MS
The software stacks are available for licensing as a platform independent ANSI C code or also available on Intel based DSP SoC platform. The stacks have been deployed as part of various WiMAX and modified WiMAX networks. The stacks have interworked with third party implementations. Target applications are
- Smart Grid ( WiGRID Networks)
- AeroMACS (Aeronautical Mobile Airport Communication System)
- Network for Oil and Gas
- Rural broadband networks
Lekha has extensive experience of testing the products for WiMAX certification we offer support to customers to go through the certification process and deployment.
