  2. 1. Low-Power Secondary Access to the TV and Aeronautical Bands

    Author : Evanny Carol Obregon Gamarra; Jens Zander; Ki Won Sung; Ben Slimane; Jonas Kronander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary Access; Interference Management; TV band; Aeronautical Band; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : The avalanche in mobile data consumption represents a big challenge for mobile operators. The efficient use of radio resources, e.g. technology, infrastructure and spectrum, is needed to meet the new capacity requirement in the mobile networks. READ MORE

  4. 2. Efficient Spectrum Utilization of Uhf Broadcast Band

    Author : Lei Shi; Jens Zander; Ki Won Sung; Linda Dolye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TV White Space; CellTV; UHF Band; Spectrum; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The UHF band between 470-790 MHz, currently occupied by digital ter- restrial TV (DTT) distribution in Europe, is widely regarded as a premium spectrum band for providing mobile coverage. With the exponential increase in wireless data traffic in recent years, there has been growing interests in gaining access to this spectrum band for wireless broadband services. READ MORE

  5. 3. Availability Assessment for Secondary Access in TV White Space

    Author : Lei Shi; Jens Zander; Ki Won Sung; Tim Irnich; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent years, the rapid growth in wireless data traffic has posed not only unique opportunities but also great challenges for the wireless industry. In order to meet the growing demand without excessive cost or energy consumption, one feasible option for the operators is to acquire more spectrum for wireless communication. READ MORE

  6. 4. On Finding Spectrum Opportunities in Cognitive Radios : Spectrum Sensing and Geo-locations Database

    Author : Mohamed Hamid; Ben Slimane; Niclas Björsell; Muhammad Imadua Rahman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; COgnitive Radio; Dynamic Spectrum Access; Spectrum Opportunity; Spectrum Sensing; GEo-locations database;

    Abstract : The spectacular growth in wireless services imposes scarcity in term of the available radio spectrum. A solution to overcome this scarcity is to adopt what so called cognitive radio based on dynamic spectrum access. READ MORE
