1. Wireless Communications Seminar in Siofok ELVA-1 Family of Broadband mm-wave Radios September 22, 2005 Sergey Berezin Marketing www.elva-1.com

2. Why the using of mm-waves are so interesting for communications? What radios we currently produce? Who are competitors? What is the difference between our solution and solution of competitors? What will be next steps in product roadmap? Program of presentation

3. What is good in mm-waves and what game rules are already established? Huge frequency band is available => huge speed of data transfer In US: in November 2003 Federal Communication Commission allocated about 14 GHz in new frequency bands 71-76 / 81-86 GHz and 92-95 GHz for high speed point-to-point radios 1...10 Gbps, FCC № 03-248 In Europe : since 1999 frequency band 40.5-43.5 GHz is allocated for for Broadband Point-to-Multipoint Multimedia Wireless Systems (MWS), ETSI EN 301 997-1(2) In Russia: since 2000 the frequency band 40.5-42.5 GHz is allocated for Broadband Point-to-Multipoint Multimedia Access and digital TV. Our company obtained permission to produce and sell radios for 40.5- 43.5 GHz. The frequency range 57-64 GHz is license free in many countries

4. Mm-waves penetrate fog and smog Investigation of volcano by mm-wave radar ELVA link as back-up to FSONA 1.25Gbps

5. Where we already use mm-waves?

6. What else is good in mm-waves except speed of data transfer? No beam crossover. Mm-wave radios are something between FSO and traditional microwave radios (below 40GHz) “Pencil-beam” 0.6-1.2 degrees at reasonable size of antenna 24”-12” Effectiveness of reflection and multi-passing effect is very week Revolutionary simplification of license formalities due to nature of mm-waves

7. Numbers arguing for themselves Based on RHK and Cisco market research (which widely made public across marketers), There are about 8000 fiber hotels (POPs) in US today 750k business buildings in US with >20 employees plus about 3000K small business locations Only ~5% of buildings have fiber connections today ~75% of these buildings are within 1 mile of a Fiber Fiber trenching has declined due to economic and municipal conditions The opportunity is to bring buildings online with fiber- like capacity using mm-wave wireless Source: 02-146 ExParte FCC WTB Filing by Cisco Systems, May 16, 2003

8. Mm-wave radio is main stream of development for broadband communications Huge frequency band available Last mile solution at speed of fiber optics, but without problems and expenses connected with fiber installation (trenching + lawyer expenses) There are already established rules for using of mm-wave bands in US and in Europe, which dramatically simplify formalities. We have technology to build Broadband Communication Systems at mm-waves

9. What Point-to-Point radios we produce? 100 Mbps Fast Ethernet LAN bridge 155 Mbps STM-1 155 Mbps «100Mbps FE + 8xE1» 1.25 Gbps Gigabit Ethernet LAN bridge

10. What Point-to-Multipoint radios we produce? “City-А”: full duplex radio 100Mbps Fast Ethernet with TDMA “City-A/1000”: at design stage “Сity-1”: Broadcasting of DVB-S Digital TV + IP (3.24 Gbps per 90 ° sector)

11. City-A principle of operation World record for speed of data transfer in return channel for Time Division Multiply Access mode 100 Mbps now -> 1Gbps will be soon
