Virtualization of the wireless link. Evaluation of scenarios with one computer and a one single virtual access point (1c1ap); two computers and one access point (2c1ap); two computers and one access point (2c1ap); and two computers and two access points (2c2ap). a The added delay which is perceived by the devices is lower than 10 ms, even when the delay between the gateway and the NFVI is 100 ms. b The aggregated bandwidth when using two computers and two access points is greater then in other scenarios
