Patent
Wireless communication system and method of wireless communication
TL;DR: In this paper, a technique that can effectively utilize unused wireless link and realize high-quality wireless communication between a communication terminal and a base station and enable efficient distribution of radio resources over an entire wireless communication system is provided.
Journal ArticleDOI
Design considerations of IEEE 802.15.4m low-rate WPAN in TV white space
TL;DR: An overview of technical design considerations for IEEE 802.15.4m LRWPAN operating in TVWS and the PHY and MAC layer designs, which are crucial for meeting the criterion of optimizing LR-WPAN performance to support potential applications, are studied.
Patent
Communication connection device
TL;DR: In this article, the authors present a technique capable of processing to automatically and optimally select types of external networks and a communication system, and at the same time, capable of switching network selection upon a user's arbitrary opportunity.
Proceedings ArticleDOI
Physical layer design and performance analysis on multi-Gbps millimeter-wave WLAN system
TL;DR: In a realistic 60GHz channel based on measurements provided by 802.11ad, OFDM has gained better performance than SC with hardware impairment under NLOS situation using directional antennae.
