Radio Enhancements from 2G/ 3G/ 4G/ 5G

Radio has always remained as one of crucial resources to wireless technology. They are always first to go into factory to look upon and improve the existing design/ architecture/ philosophies to give better user experience of the core/ back-haul capabilities. https://www.netmanias.com/en/?m=view&id=techdocs&no=13463 more to come ..

Transport Evolution - UDP - TCP - SCTP - MPTCP - QUIC

The transport has gone for several churn to cater to different requirements at each occassions. Currently after having experiences with SCTP/ MPTCP, the transport is getting one more re-calibrating as QUIC (google experiment) ...... to be updated in coming days. Main aim remains to be as light as UDP and still provide some reliability as TCP but not all. QUIC is an experimental projects towards same. Though the TCP was consistently used over the years and enhanced to mitigate the security/ reliability/ performance aspects. Its defeating the market progression to cloud. Cloud has made new technical advancements for the framework/ protocol/ environments where things can be deployed faster and analysis & results are much faster and quicker. Then our traditional OS based layering and very hard coupling and similarly tedious releasing it for usages and subsequently rollbacks and rollouts processes. Hence the experiment by google QUIC to decouple some of TCP sort of features from

HTTP progression to 5G telecom

HTTP/2.0 path chosen in 5G wireless technology !! Aka HTTP/2, published as  RFC 7540  in May 2015. HTTP/1.0 releases since 1995 and update by HTTP/1.1 in 1999. For last 20 years the web has transformed and evolved multifold but not HTTP protocol. During these years there were improvement done to HTTP/1.1 from web developers and browsers to improve the user experience. But these changes never made as standards and remains in their own world of web users/ developers for being experienced. That brought difficulty in following terms, Still not optimized enough to meet the full bandwidth utilization. Web design/ maintenance were becoming complex as there exists multiplicity of improvements segregated around the internet. HTTP/2.0 introduced improvements, Multiplexing/ Concurrency Stream Dependencies Header compression Server Push In some cases, the various improvements developed on HTTP/1.1 by individual browser providers became redundant with HTTP/2.0 Best of all, t
