2025 年 4 月 30 日,阿根廷国家通信管理局 (ENACOM)通过第 640/2025 号决议重新定义了移动卫星频谱,以减少对个人通信服务 (PCS) 的干扰。这一变化直接影响在阿根廷国家网络内运营的电信和卫星运营商。重新定义后的频谱为:
– 1990-2025 MHz 用于地对空传输;
– 2170-2200 MHz 用于空对地传输。
On April 30, 2025, the Argentine National Communications Authority (ENACOM) redefined the mobile satellite spectrum through Resolution No. 640/2025 to reduce interference to personal communication services (PCS). This change directly affects telecommunications and satellite operators operating within the Argentine national network. The redefined spectrum is:
– 1990-2025 MHz for ground-to-space transmission;
– 2170-2200 MHz is used for air-to-ground transmission.
