The millimeter wave band will be a key component in the next generation wireless communication system (5G), and a proper channel model is needed for developing the future 5G cellular technologies. This paper introduces a 28 GHz channel sounder based on automatically rotating horn antennas with time synchronization ability between the transmitter (TX) and… (More)
This paper provides an overview of research challenges and opportunities on mm-wave communication in the fifth generation (SG) mobile broadband networks. More specifically, different challenges, i.e. spectrum, propagation channel, cost and energy efficient aspects, from the perspective of mm-wave communication are discussed. Furthermore, insights on… (More)
Tumoral calcinosis is a rare benign disease entity that mimics a neoplasm and is manifested by calcium deposition in the soft tissues around the large joints. It can be primary or secondary to renal failure and hyperparathyroidism. This is, to our knowledge, the first reported case of tumoral calcinosis in a Hispanic male with rheumatoid arthritis.
