Presenter: Ramneek Chopra, Director & CEO Thunderbird Industries Slide 10 Spectrum Issues Planning –NFAP 2002 A very commendable Job by Wireless Planning Cell Seldom thoroughly referred to by decision makers –Where is the spectrum for Trunking? The NFAP says 800 MHz – we all know that But it also says 400 MHz – which very few know. International Conformity –Europe example NATO vacated 380 – 400 MHz for TETRA Is there anything that WE can do for India?

Presenter: Ramneek Chopra, Director & CEO Thunderbird Industries Slide 11 Market & Competition Military Public Access (large clients) Public Safety CDMA APCO25 GSM-R GSM iDN™ Public Access (small clients) Long Haul Railways

Presenter: Ramneek Chopra, Director & CEO Thunderbird Industries Slide 12 Myths - Tetra Expensive: TETRA > APCO25 –Hybrid Systems –Overall package with terminals is cheaper –Coverage TETRA: Low Power = More cells = more $$ Suitability for Railways: GSM-R > TETRA –GSM-R more cost effective Can use low $ Terminals (“cell phones”) in GSM-R Can Lease capacity from existing operators –Railways applications on GSM-R only UIC considers ETCS is possible with GSM-R only.

Presenter: Ramneek Chopra, Director & CEO Thunderbird Industries Slide 13 About Hybrid Systems Weaknesses in existing Hybrids –Migration to digital is not seamless Existing VHF/ UHF systems are not integrated Integrates to a particular APCO16 system only Analog compatible TETRA –Merge MPT1327 and/or plain VHF/UHF –Mixed Talkgroups but no change in TETRA Air Interface –Advanced features: Signaling Translation

Presenter: Ramneek Chopra, Director & CEO Thunderbird Industries Slide 14 Adoption Strategy Spectrum Allocation –ITU Support recommendations to regulatory Authorities Marketing Activities –TETRA MOU Support Involve Local policy makers: DCPW, RDSO /IR Board Newsletters, invite to TWC and other TETRA developments –Industry Support Promote Vertical Specific applications like AVLS, Data Transactions, SCADA, Train Control etc. Partnering with Allied firms for GIS, SCADA RTU etc
