What is DSRC?


DSRC (D= edicated Short-Range Communications) is a wireless communication technology= that enables vehicles to communicate with each other and other road users = directly, without involving cellular or other infrastructure=2E DSRC is bas= ed on WiFi technology

As expected this technique is designe= d to allow exactly what NN was designed to prohibit (treating packets diffe= rentially in the internet based on economic considerations*)=2E=2E=2E this = is IMHO why instead of calling a spade a spade mobile carriers avoid descri= bing this in a useful way, as it is exactly about prioritisation=2E=2E=2E I= MHO that will back fire, and a better avenue would be to be open about what= it enables and propose a method to restrict the potential issues=2E E=2Eg= =2E (I am making this up on the fly, so it will likely not hold up to any d= egree of scrutiny) by self limiting to never commit more than X% of a cell'= s capacity to slicing, IFF the cell is used for normal end user service at = all=2E So admit that there is some trade-off here, limit the fall-out, and = then describe why we as a society should embrace that trade-off=2E I am a bit sceptical about the whole car 2 car c= ommunication thing (that is cars talk to cars, not people n cars talk to pe= ople on cars ;) ), but if a Carrier believes there is value in that for e= =2Eg=2E accident avoidance, then tell how this requires the stricter networ= k guarantees that (only?) slicing can deliver=2E

[RR] V2X communications for saving lives wi= ll NEVER go through ANY carrier=E2=80=99s network in spite of what you hear= =2E  There is simply no way anyone is going to pay to have BSMs broadc= ast 10 times a second to prevent accidents, and NO CARRIER is going to give= that capacity away for free, even if they had enough to carry the traffic,= which they do not by many orders of magnitude!!!  More importantly, t= he information being exchanged does NOT require a network to get where it n= eeds to go!  The 5G hype you hear from various carriers and equipment = suppliers related to V2X communications is all powerpoint BS (to make share= holders happy)=2E And there is a ton of it out there!
