Az Phase I. haszn\u00e1lati esetek az olyan \u00e1ltal\u00e1nos elemekkel foglalkoznak, mint p\u00e9ld\u00e1ul a “White-Box” hardver, a forgalomir\u00e1ny\u00edt\u00e1s (Traffic Steering), a QoS\/QoE optimaliz\u00e1l\u00e1s vagy a massive MIMO. Ezek kiemelt fontoss\u00e1g\u00faak, mivel szorosan kapcsol\u00f3dnak a legt\u00f6bb \u00fczemeltet\u0151 \u00e1ltal kezelt forgat\u00f3k\u00f6nyvekhez.<\/p>\n\n\n\n
