MSK attractive for high volume, low power, low cost “point-and-shoot” applications at multi-Gb/s
No ADC or high-speed digital baseband required, can make a low-power product today
We believe the standard should be defined to include both MSK and more complex modulation schemes
We are not opposed to other solutions and modulations; they will be essential for many applications. But we see MSK as an excellent choice for lowest power, reduced complexity and quick time to market
Current transceiver implementation supports both an universal I/Q interface to support a variety of modulations as well as FSK/MSK modulation/demodulation capabilities.
From a radio perspective, the overhead to support MSK is negligible
An MSK-based system for multi-GB/s comm. at 60GHz presents significant advantages (i.e. lower complexity and power consumption) in a directional channel
FM / FSK detector has been characterized in a 2-Gb/s 60-GHz video link
Integrated MSK Transmitter has been demonstrated
Full TX and RX with MSK mod / demod have been fabricated, characterization for a high data rate link will follow
We are not opposed to other solutions and modulations; they will be essential for many applications. But we see MSK as an excellent choice for lowest power and complexity, especially for usage model 5
