Media access controllers receive approval
The RTU7300 and RTU7105 meet the WiMedia MAC specification, designed to enable flexible formation of wireless personal area networks and co-existence between devices supporting different protocols
Realtek Semiconductor's RTU7300 ultra-wideband media access controller (MAC) and RTU7105 single-chip combined ultra-wideband MAC and physical layer (PHY) solution have achieved approval as WiMedia Certified Platforms, as part of the first set of platform certifications from the WiMedia Alliance.

The certification establishes the full compliance of the RTU7300 and RTU7105 with the WiMedia MAC specification, which is designed to enable flexible formation of wireless personal area networks and co-existence between devices supporting different protocols, including Certified Wireless USB, next-generation Bluetooth and IP-over-UWB.
WiMedia Platform Certification is required for all devices implementing the WiMedia MAC specification, including all Certified Wireless USB and next-generation Bluetooth devices and represents the second and final required component of the WiMedia certification process.
'Completion of the WiMedia Certification Program is a major milestone for the ultra-wideband industry, finally enabling shipment of products and assuring customers of the interoperability of devices from multiple vendors', said Ran Yan, Senior Vice President, Wireless Communications Technologies at Realtek.
'The RTU7300 and RTU7105 are the first in a series of Realtek product offerings that will provide support for Certified Wireless USB, next-generation Bluetooth and the WiMedia Alliance IP-over-UWB protocol'.
The WiMedia MAC protocol contains many novel features that are designed to maximise suitability for wireless personal area network applications.
These features include the fully distributed nature of the MAC.
There is no requirement or provision for central control of the network, enabling any two devices to form a network.
The MAC enables co-existence of multiple simultaneously operating higher-level protocols that can partition use of the wireless medium efficiently.
In addition, the MAC emphasises reservation-based channel access, minimising required power consumption and building on the advantages of the underlying ultra-wideband physical layer technology, which itself enables much lower power consumption than is possible with other wireless technologies.
