ZTE Corporation and MTN announced the successful commercial deployment of the world's first 5-band Remote Radio Unit (RRU). This milestone, achieved in South Africa'sWestern Cape Province, represents a significant breakthrough in global radio frequency technology and injects strong momentum into the technological evolution of Africa's telecommunications industry. As one of Africa's largest and most advanced telecommunications markets, South Africa serves a population of over 60 million people, with MTN providing more than 97% LTE population coverage across the country.
This extensive reach reflects MTN's commitment to delivering high-quality communication services to even the most remote communities. With increasing demand for multi-band and multi-module services, network operators face mounting challenges such as power consumption, tower load, and limited space, all of which can hinder the evolution of mobile networks. The recent deployment of MTN's 5-band RRU directly addresses these issues.
This innovative solution improves network performance, enhances energy efficiency, and simplifies deployment processes, enabling faster and more sustainable expansion of next-generation connectivity. New frequency bands on a mobile site require new hardware and additional space and power. The 5-band RRU, powered by ZTE's in-house design chipset, integrates all MTN South Africa's low and mid bands (FDD) into a single compact unit.
This integration reduces the number of RAN Radio Frequency modules on towers by 50%, decreases equipment weight by 23%, and minimizes wind resistance by 18%. These optimizations streamline site construction, reduce deployment complexity, and free up valuable space on towers. In addition, ZTE's innovative Super-N amplifier architecture utilizes dense arrays of power amplifiers with on-demand activation capability.
It overcomes the efficiency bottleneck of traditional Doherty architecture and maintains high efficiency under varying loads, achieving a remarkable 42.7% reduction in overall site power consumption and a 45.8% improvement in energy efficiency (Wh/GB). This not only supports South Africa in building a green, low-carbon society but also sets a new benchmark for sustainable development in the industry, demonstrating the immense potential of technological innovation in balancing economic and environmental benefits.
