Together with GSMA Intelligence and ITU, Huawei successfully hosted the LATAM ICT Congress 2022, aiming to build a global industry communication platform and promote the rapid development of 5G and digital transformation in Latin America. Representatives from operators, regulators, industry organizations, 5G ecosystem partners, analysts, and media partners attended the congress.
During the congress, Vice President of Huawei 5G Product Line, Fang Xiang, delivered a keynote speech titled Innovation for a Golden Decade of 5G in LATAM. In his speech, he said, "simplified and green 5G networks that deliver a cross-generation experience are fundamental to 5G business success. Huawei is committed to bringing ultra-wideband and multi-antenna technologies to every frequency band and scenario through continuous 5G innovation, to build a ubiquitous, simplified, and high-capacity target network and usher in a golden decade of 5G in Latin America."
5G development is accelerating in Latin America. In the past two years, countries such as Brazil, Mexico, Chile, and Peru have started the commercial deployment of 5G. While launching 5G packages and enjoying digital dividends, operators are actively exploring new services for individual consumers, families, and industries.
After more than two years of practice in commercial 5G deployment, ultra-wideband and multi-antenna technologies stand out and have become the first choice for most operators. "As the pace of 5G spectrum distribution varies across countries and the TDD and FDD spectrums have different characteristics, operators face different challenges in 5G network construction," said Fang. "However, all operators share the same goal: to move towards one network on multiple TDD and FDD bands and build simplified and green networks that deliver a cross-generation experience."
The TDD ELAA-Massive MIMO Enables Optimal Performance and Energy Efficiency
It has become an industry consensus that Massive MIMO is the right choice for deployment with continuous large-bandwidth TDD bands. Huawei's MetaAAUs introduce a new architecture — extreme-large antenna array (ELAA) — which supports doubling the array scale. They enable base stations to provide wider coverage with the same transmit power or provide the same coverage with a lower transmit power, reducing energy consumption by about 30% compared with conventional AAUs.
"ELAA innovates the new direction of improving coverage while reducing energy consumption. With the new architecture and algorithms, MetaAAU improves network performance and enables energy saving, helping operators build high-quality green 5G networks," Fang said.
The FDD Ultra-Wideband Multi-Antenna Solution (4T-8T-Massive MIMO) Maximizes Spectrum Value
Based on the characteristics of FDD spectrum, ultra-wideband and multi-antenna technologies can be used to maximize spectrum value and improve the experiences provided by and capacities of 4G and 5G.
For the scenarios of evolution to 5G, Huawei has launched the highly integrated ultra-wideband 4T4R RRU. It supports simplified deployment of 700–900 MHz/AWS + PCS multi-band networks. Full-band and all-RAT dynamic power sharing helps it improve user experience by 20% and reduce power consumption by 20%. Huawei has also launched the ultra-high-power ultra-wideband 8T8R RRU. Supporting AWS and PCS and working with the Hertz platform 8T8R antenna, it can improve the coverage and capacity significantly. Towards 5G, it is believed that hardware and software innovation alongside intelligent radio management are the best way to improve energy efficiency instead of purely increasing power levels.
For scenarios where large capacity is required but the antenna space is limited, Huawei will launch FDD BladeAAU next year. It integrates FDD Massive MIMO and full-band antennas, addressing deployment challenges.
For markets in which new 5G bands have not been provisioned, ultra-wideband and multi-antenna technologies can be used to reduce deployment costs for upgrading existing sites, improve the experience provided by and capacity of 4G, and support evolution to 5G (including voice and IoT services).
The Intelligent Multi-Band Coordination Solution (HashBAND) Ensures the Optimal Experience
For future 5G networks where FDD and TDD multiple bands co-exist, Huawei has created a multi-band coordination solution — HashBAND. It enables intelligent coordination among different 5G bands to expand mid- and high-band 5G coverage while improving low-band user experience at the cell edge, bringing multi-band value to customers' networks and improving the 5G user experience.
In terms of 5G, it is believed that the best way to meet the increasing power requirements is by improving energy efficiency through hardware and software innovation as well as intelligent radio management, not simply increasing power levels. This is also the best way to green development.
