The future of mobile
Data transmission is in a relatively early stage of development, even though the services being offered do include email and moving images.
QCIF and Mesaplexx are working on new technologies to create products that radically improve the performance of mobile cell sites.
As mobile internet becomes more integrated into everyday work and leisure activities there will be a need for increasingly sophisticated services, and the capacity of the wireless networks will need to be significantly increased.
The next generation of wireless telecommunication systems, which will be deployed in the 2012-2015 time scale, will be known as 4G (4th generation) networks and will require a 10 - 20 times increase in data rates as compared with existing 3G networks. The underpinning technologies for these networks are the components that transmit and receive Radio Frequency (RF) signals.
Outcomes
The purpose of the project is for QCIF to provide the facilities and software packages, VASP and ABINIT, to test convergence and performance parameters for DFT simulations of temperature coefficients and Q, and to compare the VASP versus ABINIT pseudo-potentials. The use of high performance computing is essential for the lowering the time for development of low temperature coefficient (Tcf) and high quality factor (high Q) ceramics for wireless telecommunication systems.
At the core of the Mesaplexx technology platforms are the new electroceramics used as components in microwave filters. Mesaplexx is presently developing new electroceramics and dielectric ceramics that significantly improve performance of the RF equipment. These new electroceramics are required to have very high quality factor (Q) and a low temperature coefficient of the dielectric constant (Tcf) To achieve this outcome the engineers use first principles density functional theory (DFT) computational methods to simulate the properties of dielectric ceramics. By combining actual synthesis with the computational 'virtual laboratory' it will be possible to quickly and efficiently build a properties matrix for the electroceramics of interest. This use of a 'virtual laboratory' reduces costs and facilitates the faster development of new products.
