WirelessPAN (UWB)
 
   
  Advanced UWB Technology Development Platform
   
 

Ultra wideband (UWB) is anticipated to be widely adopted in PC peripherals (e.g. Wireless USB) and consumer electronics products, providing shared access to the radio medium, with QoS, power management and security features. ASTRI’s UWB R&D includes the development of a WiMedia-compliant multi-band OFDM UWB platform solution. This flexible and scalable UWB design platform features 4 patent-pending advanced algorithms, providing multi-hop capability, efficient transmission power control, intelligent resource scheduling and dynamic bandwidth allocation functionalities.

Using this advanced UWB platform as a basis, sophisticated solutions for various applications, such as wireless USB or wireless multimedia products, can be built. The platform becomes an adaptable design as the capabilities and functions for different products can be incorporated as required, generating competitive derivative designs in terms of performance and cost-effectiveness.

Multi-hop Network Technology
expands conventional network coverage extensively by employing ASTRI's patent-pending multi-hop routing scheme. A node in a multi-hop network functions as a router to relay messages intelligently.

 
Transmission Power Control (TPC)
not only extends the battery life of portable devices, it also enables the reuse of bandwidth through power reduction. A balance between the usage gain and the degradation in performance is the key to the success of this algorithm.

Distributed Resource Allocation Scheme (DRAS)
enablesthe efficient and effective usage of limited resources in a decentralized network. The challenge lies in the fact that there is no central controller to manage such resource scheduling. DRAS includes two components: DISCO, which allocates resources according to link quality, and dynamic bandwidth allocation (DBA) where resources will be shared according to usage requirement.

 
Distributed Intelligent Scheduling for Compensation Optimization (DISCO)
By re-allocating resources from a communication link with significant fading effects to a better communication link, the transmission success rate can be increased and the resources can be viewed as more effectively used.

 
Dynamic Bandwidth Allocation (DBA)
By predicting the bandwidth requirement in variable bit rate situations and re-allocating resources from a link with little traffic to one with more traffic, resources can be used more efficiently to achieve better QoS
