Spectrum Trading for Efficient Spectrum Utilization

Spectrum Trading for Efficient Spectrum Utilization

The conventional command and control based spectrum management has led to substantial underutilization of some spectrum bands while severely crowding others due to the uneven and dynamic needs that vary over time and at different locations. Spectrum trading has emerged as a promising management approach to substantially improve spectrum utilization and user experience in wireless communications...

Efficient Spectrum Utilization of UHF Broadcast Band

The UHF band between 470-790 MHz, currently occupied by digital terrestrial 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. The secondary access in TV White ...

Coopetition spectrum trading - Creating endogenous spectrum holes

Dynamic spectrum access is an important way to alleviate the spectrum scarcity. Traditionally, secondary users are allowed to opportunistically operate when primary users are absent and buy idle bands from primary users. Although it improves the spectrum utility to some extents, it is not enough. In this paper, we argue that spectrum hole should be endogenous which means they should be negotiat...

Congestion Game Model for Efficient Utilization of Spectrum

Dynamic spectrum access is a way of gaining access to individual frequencies on a temporary basis. This makes use of the frequency assigned to a specific user (primary user) by using specific devices and/or spectrum management techniques. The spectrum management techniques can be done by allocating the spectrum (a) through auctions (market based), (b) using management techniques (c) spectrum sh...
