Ultimately this will come down to market demand. Having led two efforts in IEEE to develop a next speed of Ethernet - I have heard the argument about needing the next speed of Ethernet. Ultimately, market demand showed that it was necessary and we had done the right thing developing the next speed. So given the cost of deployment - will the business case to deploy 5G happen? Had lots of conversations with people on this. Would like to better understand this as we start to look beyond 400GbE - as bandwidth related to 5G is frequently brought up. -----Original Message----- From: NANOG <nanog-bounces@nanog.org> On Behalf Of Matt Hoppes Sent: Monday, December 30, 2019 9:24 AM To: Mark Tinka <mark.tinka@seacom.mu> Cc: nanog@nanog.org Subject: Re: 5G roadblock: labor We saw this with Femtocells. Why build the network when the end user will build it with their broadband connection? With 5G - if I need fiber to the pole already and the pole has to be within. Few hundred feet of the end user, why not just deploy fiber to the home? Do I really need a gigabit per second on my mobile device?
