corDect Development

corDECT/EDWAS is a fixed WLL solution developed by Midas Technologies along with IIT-Madras and Analog Devices. This is a cost effective solution for providing last mile connectivity.

RBS Development Cycle

Relay Base Station, a propriety product of Midas, is an Active wireless repeater which is used to extend the range of corDECT to 70 km, from BTS. Involved in development of various features of RBS viz,

1. Remote Monitoring of Relay Base Station

Designed and developed Remote Monitoring feature for RBS. Work involved design & development of Application Layer and changes at MAC layer for realizing the same.

Language: ADSP Assembly, C

2. Improvisation of Channel Selection Algorithm of RBS.

Designed and developed a new channel selection algorithm (MAC Layer) which is more robust & dynamic, which will improve the performance of RBS in an interfering or error prone environment.

Language: ADSP Assembly, C

3. Fine Tuning of Software Modem at RBS

The Software modem, which is used to decode the on-air reception and identify DECT pattern, was fine tuned to produce more robust results in an interfering environment. Work involved understanding and debugging of physical layer signal processing algorithms and problems identification.

Language: ADSP Assembly, C

FST Development

FST (Field Survey Tool) is a proprietary product of Midas is a user friendly DECT based RF-Survey Tool used for Pre-Installation of corDect installation. Involved in development of ADSP based assembly drivers for LCD, Keypad, RTC, tailoring of MAC Layer
