ACSA

ACSA (Airports Company South Africa), operating within South Africa, is a unique mobile network identified by its Mobile Network Code (MNC) of 75 and Mobile Country Code (MCC) of 655. Unlike major South African mobile operators like Vodacom or MTN, ACSA's network isn't designed for public mobile subscriptions. Instead, it's primarily dedicated to serving the communication needs within and around South Africa's airports. This specialized application makes it a critical piece of infrastructure for airport operations. The ACSA network likely supports various airport functions, from internal communications and security systems to logistical operations and potentially passenger services like dedicated Wi-Fi hotspots or data transmission. Although specific details on the technology ACSA employs are often proprietary, it's probable the network uses a blend of technologies tailored for reliable, secure communication in a high-traffic environment. The MCC 655 designation, placing it within South Africa's telecommunications landscape, highlights its integration within the country's broader network infrastructure, while the MNC 75 distinguishes it from other publicly facing providers. Its contribution to airport efficiency and safety underlines its significance within the South African transportation sector.
