Next Generation Networks: Whence, Where, and Whither
نویسنده
چکیده
The last decade witnessed many Next Generation Networks (NGN) with each having a short life of only few years. The SecondGeneration Network (2G), which is already out of vogue in most advanced countries, is still being deployed in third world countries. The ThirdGeneration (3G) Network was expected to solve all the problems encountered in the previous generations, but the persistent demand for higher rates and the non-compatibility of the 3G standards has shifted the enthusiasm to Beyond 3G (B3G) or Fourth-Generation (4G). This paper re-examines the various generations of network standards with the intention to focus the mindset of the telecom planers and designers and also raise their research consciousness. (

Our main response is gratitude at DGR's agreement with the main theses of "Whither Reform?" such as the critiques of voucher privatization and of the attempts to quickly install institutional reforms...
متن کاملLifetimes of Heavy-flavour Hadrons – Whence and Whither?
A theoretical treatment for the weak decays of heavy-flavour hadrons has been developed that is genuinely based on QCD. Its methodology as it applies to total lifetimes and the underlying theoretical issues are sketched. Predictions are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly shorter than expected. The ramifications of those fi...
