European satellite navigation competition 2010

  1. 1. EUROPEAN SATELLITE NAVIGATION COMPETITION 2010Section A: Technical aspects Developing cognitive radio receivers for 802.22 /WRAN (wireless Radio Area network) using GNSS (Galileo).The need for effective utilization of the radio spectrum has become an importantarea of research in the field of wireless communications. Today, wireless devicesuse fixed bands in the spectrum allocated by standardizing committee like the LTE 1and FCC2. FCC has conducted various studies on the under utilization of theallocated spectrums3 .One such frequency band is the TV signal band (VHF and UHFband). FCC has come up with the 802.22 standard for development of broadbandservices in these bands. We propose a product that will enable the deployment ofWRAN technology in the future. As a first step, the company will develop efficientand robust ‘cognitive receivers’ which can be plugged into a computer to operate ina WRAN network for fixed users. Future prospects include using such receivers inhandheld and portable devices.Improvement on existing solutionThe current limitation of wireless technologies like Wi-fi , Wimax is the short areacoverage . A number of routers, base stations and repeaters are required forexpansion of the network. A “cognitive receiver” offers solutions for wide areadeployment of networks at a respectable data rates.Technology SpecificationsThe technical specifications of WRAN networks have already been decided by FCC.Some important specifications are • A VHF/ UHF band network (US :54-72 MHz ,76-88Mhz ,174-216 MHz, 470-806 MHz) • Cell radius: 17 – 33 Km.1 Long Term Evolution2 Federal communication Commission3김김김.pdf
  2. 2. • Point to multipoint network topology • Use of GPS mandatory • For fixed and mobile users (802.22 PHY standard for mobile users) • 6 MHz bandwidth , 1.5 Mbps downlink /384 Kbps uplinkAn important aspect of our product is the antenna efficiency and size. For fixedusers, our device will use the TV antenna of the user to set up a WRAN network .Incase the user doesn’t have an antenna, customized antennas will be sold with ourreceivers . As the size of the antenna is not critical for fixed users, these antennaswill be designed to work at lower frequencies of the TV band spectrum. For mobile users, the antenna size has to be small. This is possible bydeveloping “cognitive receivers” for higher frequency of the TV band spectrum. Advantages of our product • Will work in a large dedicated data network area coverage( upto 100 Km theoretically) • Lower cost of setup ( few base stations and repeaters compared to 802.11 and 802.16) • Deeper penetration of data networks (internet) in developing countries. • An alternative wireless solution to fixed data networks.This product will make internet more ubiquitous due to its long range wirelesscapability. It can provide internet speeds similar to ADSL and cable modem in lesspopulated areas. In cities, it can provide lower speed access to internet like thoseavailable on 3G and GPRS 4 technology. An impending problem of large usage ofbandwidth by 3G phones will be solved by using dedicated WRAN networks forestablishing data communication networks. The use of GNSSGalileo GNSS will be an essential entity of 802.22 wireless communicationstandards. A WRAN base station and its community of users will share a common4 General Packet Radio ServiceProposed by Mayur Sarode and Trinath Chigurpatti Page 2

These parameters will improve the robustness of the cognitivereceiver in following ways • Accurate synchronization with the base station • To detect if the CPE(customer premises equipment) is within or outside the protected contour of a licensed spectrum • The base station will be equipped with GPS which will communicate with a centralized database to give information about available free channels and guard bands in the area • Using Galileo GNSS to monitor the inflow and out flow of users in within a WRAN cell.Making the product a reality!For proof of concept, USRP 5 boards and open source Gnuradio software packagescan be used to develop software for efficient spectrum sensing. After establishingfor robustness of the software, specialized RF front ends will be developed usingthis software to market a WRAN compatible plug and play device with a personalcomputer. Development of antenna’s first for fixed users and then for mobile userswill also be undertaken . For deploying WRAN network base stations, third partiesnetwork service providers can be approached or developed in house. Existing GSM 6,mobile networks infrastructure, can be considered for WRAN setup.Has the idea been tested already?A lot of research is being conducted in the field of cognitive radios [1]. FCC is in theprocess to set the standards for spectrum sensing. There is a large open sourcecommunity on web working on developing cognitive radio protocols. 7Public abstractAs more and more of devices are communicating wirelessly, the spectrum availableto accommodate these devices are limited. Most of the frequency spectrum is5 (Universal software radio peripheral) ( Global System of Mobile7 by Mayur Sarode and Trinath Chigurpatti Page 3

Our company proposesto build reconfigurable radio’s in the UHF/VHF 8 band which have previously beenlicensed to television operators by following the 802.22 standard and specifications.With a wide network area and data rate speed similar to ADSL 9 and cable modem, alarge market is foreseen in providing fixed and mobile internet access. Our productwill also be an economical solution to connect users at rural and remote places tothe internet grid.Section B: Commercial aspectsAppropriate business sectorThe business sector of the product is in the field of telecommunications and mobilephones. This product will expand the reach of internet to remote and rural area.This will increase E trade and commerce. The product has the opportunity to make profits in developing countries (Africa,India and china), where internet access is limited. Figure 1 shows the projectedgrowth of mobile broadband in the near future.Appropriate field of application for potential future adaptions.Potential future adaptations include embedded cognitive receivers in mobile phonesand handheld devices. WRAN network planning is another area where large returnon investment can be expected. The data speed of WRAN networks is comparableto present data rate as shown in Fig.2 with an advantage of large network area.Hence a large market exists in mobile internet.8 Ultra High frequency/Very High frequency9 Asymmetric Digital subscriber Line*Ovum ,Strategy analytics ,Ericsson ; ** Data compiled from T-mobile servicesProposed by Mayur Sarode and Trinath Chigurpatti Page 4
  5. 5. Figure 1* Figure 2** Target market CustomersThe company will initially target customers in developing countries and rural areasof developed countries. Due to limited resources of ADSL and cable internet whichare mostly restricted to large cities, WRAN networks will be a solution and will boostthe existing infrastructure of the data networks. The 8022.22 cognitive receivers forfixed equipment will have high market value in developing countries due to analternative wireless solution to ADSL and cable internet.After generating revenues from these services, mobile users will be targeted next.The main challenge lies is incorporating a WRAN receiver in handheld devices. Inthe developed countries, a large market potential exists in establishing dedicatedlong range data networks for mobile phones.To make 802.22 technologies ubiquitous and profitable to our company, apartnership with mobile service providers (T-mobile, Vodafone) and incumbent TVbroadcasters (NTSC, ATSC, PAL, DTV and DVB-T)10 is importantMarket valueThe product will have a high market value as it conforms to the industry standards.The cognitive receiver will be designed in according to the standards set by FCC.Hence market acceptance and interoperability will not be an issue.Competitors10 NTSC: National Television Service Committee ;ATSC : Advanced Television Systems Comité;Proposed by Mayur Sarode and Trinath Chigurpatti Page 5
  6. 6. To our knowledge there is one company ( which providescargo management solutions using the 802.22 standard. Other than this company,presently there are no direct competitors in this segment of market.Company internalsTo realize this product, at least a year of research and development by a small teamof engineers (2-3) is required. This can be conducted independently or at theTechnical university of Eindhoven as a part of the master’s curriculum. The cost ofdeveloping the product involves purchasing USRP test beds (atleast 2) andmanufacturing cost of receiver. Using third party to deploy base stations for WRANnetwork will also influence the cost of the receiver.The final cost of the product depends on the whether WRAN base stations aredeployed in-house or in collaboration with a network provider. The goal of thecompany will be to keep the manufacturing cost of the receiver as low as possible. USRP kit + computer +peripherals 4000 Euros (antennas ,cables, connectors) Rent Office space 400 Euros pm Final product Will be made competitive with existing solutionsTime before product launchOur company wishes to be financed either by Galileo masters award under the mainprize event or by T –systems. The ground based communication infrastructure of T-systems will allow us to test our cognitive receivers and create WRAN networks onfield.The return on investment for investors will be high as it will create a new market forfixed and mobile internet. No investment on procuring licensed spectrum is requiredas FCC has opened the spectrum for development of cognitive radios.Atleast one year is needed to conduct the proof on concept and on development oncognitive front end. Another year will be required to comply the products with FCCstandards for mass deployment of the technology. It will take around 1.5 -2 years todevelop and launch the product in market.Proposed by Mayur Sarode and Trinath Chigurpatti Page 6
  7. 7. Section C: Legal aspectsThe IEEE 802.22 standard is proposed by FCC for TV spectrums in the United Statesof America. The standard has to be modified (the bandwidth and frequency ranges)to make it more suitable for a market of a particular country. The protection frominterruption to incumbent service providers and convincing them about noninterference caused by the cognitive radio receivers will be a challenge. Onsitetesting will play an important role on the success of the product.The 802.22 standard is mainly targeted for rural and fixed equipment users. Ourcompany will carry out innovation to make it suitable for mobile users. Presently,802.22 PHY supports mobility upto 114 Km/hr. This idea is not patented butthe technology when developed has the potential to be patented.Proposed by Mayur Sarode and Trinath Chigurpatti Page 7
