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 Confidential,
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 Confidential,
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 Confidential,

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

Confidential,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
1. Peripheral Drivers for Confidential,
Development of device drivers for LCD, Keypad, RTC, GPS modules (in ADSP21xx assembly)
Language: ADSP Assembly, C

2. DECT Sniffer
Involved in Scan Mode wherein the FST acts as DECT sniffer and can listen to any DECT transmission, and display the DECT Physical and Mac Layer information to user which helps in installation and debugging. Work involves changes in Application, MAC, and Physical layer of FST for realizing the same.
Language: ADSP Assembly, C

3. RBS Configurator
Involved in development of RBS Configurator, wherein FST acts a tool to configure or upgrade RBS during RBS installation. This feature of FST replaces the Laptops which were earlier used to configure, upgrade or maintain RBS.
Language: ADSP Assembly, C
