Description:
Combines the latest trends in spectrum sharing, both from a research and a standards/regulation/experimental standpoint
Written by noted professionals from academia, industry, and research labs, this unique book provides a comprehensive treatment of the principles and architectures for spectrum sharing in order to help with the existing and future spectrum crunch issues. It presents readers with the most current standardization trends, including CEPT / CEE, eLSA, CBRS, MulteFire, LTE-Unlicensed (LTE-U), LTE WLAN integration with Internet Protocol security tunnel (LWIP), and LTE/Wi-Fi aggregation (LWA), and offers substantial trials and experimental results, as well as system-level performance evaluation results. The book also includes a chapter focusing on spectrum policy reinforcement and another on the economics of spectrum sharing.
Beginning with the historic form of cognitive radio, Spectrum Sharing: The Next Frontier in Wireless Networks continues with current standardized forms of spectrum sharing, and reviews all of the technical ingredients that may arise in spectrum sharing approaches. It also looks at policy and implementation aspects and ponders the future of the field. White spaces and data base-assisted spectrum sharing are discussed, as well as the licensed shared access approach and cooperative communication techniques. The book also covers reciprocity-based beam forming techniques for spectrum sharing in MIMO networks; resource allocation for shared spectrum networks; large scale wireless spectrum monitoring; and much more.
Contains all the latest standardization trends, such a

Best Cream!!
Love this stuff!
I got this because menopause was killing my skin. It was awful! Itchy, red and dry. I couldn't sleep it was so bad.
I found this, and it's literally the only thing that actually helped. I went through my first jar quickly, no you don't need much, but my rash was all over my arms, neck and chest.
After my second jar and using it a few times a day, my rash is gone!
Some people may not like the smell, but I think it's actually nice. It's not greasy, and I don't feel gross after putting it on. I hate greasy creams.
On my third jar now! This one is lasting much longer since I don't need it as much.

Good Relief, But a Little Pricey
I don’t usually write reviews, but I felt like this cream deserved one. I’ve tried so many products for dry, itchy eczema patches, and most either felt greasy, burned when applied, or just didn’t do much. Puriya has been such a refreshing change. The texture is smooth, it absorbs quickly without leaving that sticky feeling, and within a couple of days my skin felt calmer and the redness started to fade.
What I really like is how versatile it is. I’ve used it on flare-ups, random dry spots, and even my hands when they get irritated in the summer. It feels gentle but still effective, and I don’t need to use a ton for it to work.
The only reason I didn’t give it 5 stars is the price. It’s a little on the higher side for the amount you get. I also find myself reapplying a bit more often than I’d like. But overall, it’s one of the better creams I’ve tried, and I’ll definitely keep using it.

Not good for eczema
This cream shouldn't be described as an eczema cream. Eczema is usually colonized by s. aureus bacteria, and you need a powerful anti-bacterial substance in your skin cream in order to combat it. Neem oil or manuka honey both have strong anti-bacterial effects, and I recommend getting a cream with one of those ingredients if you have eczema. This Puriya cream is helpful for moisturizing dry skin to prevent eczema. However, it won't help to stop eczema once you've got it. That said, customer service was very helpful and gave me a refund for the product after I complained.

Very nice and moisturizing on the skin but didn't do much repairing. Overly expensive for nothing.
