vRAN? cRAN, oRAN?!!
多年來、
運營商花了大把大把的銀子、鋪蓋了寬帶高速無線網 (3G/wcdma, 4G/LTE,)、結果賺錢的反倒是矽谷那些公司、譬如谷歌、臉書、Youtube...、因著提供 所謂的 Digital Content, 反倒賺入囗袋 大把大把的銀子、
其中一項 RAN (antenna 前端接口) 成本太高了、這些成本大部分全由 Huawei/Nokia/Ericsson/ 給囊括了、矽谷那幫傢伙早就動了腦筋、想一舉將 RAN 這塊大餅吞吃殆盡?
vRAN = Virtual RAN (virtualization /software defined)
cRAN = Cloud RAN (SW then put in Cloud)
oRAN = Open RAN (open-source RAN 規格一致化)
