The Evolution of 5G
The global adoption of 5G technology has been remarkable, with over 1.5 billion users worldwide already on board. As we approach the second half of this decade, it’s evident that 5G is poised to become the dominant mobile technology thanks to continuous advancements in the field.
Since its initial launch in 2019, 5G has seen significant developments, especially regarding spectrum allocation. One innovation that is driving 5 G’s performance and deployment flexibility is Dual-band Massive MIMO (Multiple-Input, Multiple-Output) technology.
In the United States, the auction and allocation of the C-Band spectrum (3.7 to 3.98 GHz) in 2021 and the 3.45G Band (3.45 to 3.55 GHz) marked significant milestones. These auctions resulted in the availability of a substantial amount of new mid-bandwidth for 5G deployments, enhancing network performance and the end-user experience. U.S. operators quickly deployed 5G network equipment to leverage these spectrum allocations.
The Role of Massive MIMO in 5G Expansion
Massive MIMO is a key enabler of 5 G’s superior performance and involves using many antennas at the base station to simultaneously serve multiple users on the same frequency resources. This spatial multiplexing dramatically boosts capacity and efficiency in wireless networks.
Traditionally, Massive MIMO has been deployed in the sub-3 GHz frequency range, but the advent of mid-band spectrum allocations has brought new challenges and opportunities. The allocation of mid-band frequencies with much higher bandwidths, such as the C-Band and 3.45G Band, presents a unique set of requirements. Operators need high-bandwidth radio products capable of handling non-contiguous spectrum allocations effectively.
For instance, Nokia’s AirScale Osprey 64×2 meets these demands with its impressive 530 MHz instantaneous bandwidth support. This means it can efficiently cover both the C-Band and 3.45G Band, allowing operators to maximize their spectrum resources and deliver blazing-fast 5G services.
Benefits of Dual-Band Massive MIMO Radios
Dual-band Massive MIMO radios offer tangible benefits to network operators. These high-bandwidth products reduce deployment costs, site rental expenses, and overall total cost of ownership by minimizing the number of radio boxes needed. They also expedite the rollout of 5G in densely populated urban areas where space constraints often hinder the deployment of multiple radios, particularly on crowded sites. Additionally, the Osprey 64×2 boasts a high RF power output of 480W, ensuring extensive coverage in both bands, enabling larger inter-site distances, and enhancing in-building performance.
Today’s 5G networks provide a solid foundation for evolving mobile networks into 5G-Advanced and beyond. This evolution will usher in new advanced use cases and revenue streams. Nokia remains committed to developing industry-leading radio products, ensuring its customers stay at the forefront of this dynamic evolution.
Compact and Energy-Efficient Solutions
One of the challenges in expanding 5G networks is the need for compact and energy-efficient solutions. Dual-band Massive MIMO radios are designed to be space- and energy-efficient, making them ideal for compact site solutions and reducing operational costs. Their compact form factor and lower power consumption facilitate faster and more cost-effective network deployments.
Nokia ReefShark
Additionally, Nokia’s ReefShark System-on-Chip (SoC) technology – which powers these radios – enables them to support high RF bandwidths of up to 400 MHz. This allows for the utilization of fragmented spectrum and the implementation of radio access network sharing with a single antenna. The high RF output power and energy efficiency makes Dual-band Massive MIMO radios a compelling choice for operators looking to enhance coverage and capacity while optimizing their network resources.
Nokia Osprey
Nokia’s Osprey Massive MIMO radio portfolio is an industry benchmark for delivering field-proven performance and market-leading capabilities. The latest addition to the family is the dual-band Osprey 64×2 Massive MIMO radio.
Beyond high performance, this solution supports extreme RF bandwidth, making it possible to cover multiple 5G bands with a single product. This level of flexibility is crucial for operators aiming to provide comprehensive 5G coverage while efficiently managing their infrastructure.
Interleaved Passive Active Antenna (IPAA+)
Nokia’s commitment to innovation extends beyond radio products to advanced solutions like the Interleaved Passive Active Antenna (IPAA+). This modular and advanced radio solution interleaves the antenna elements of a high-performance AirScale Massive MIMO radio, either 64TRX or 32TRX, with the antenna elements of a multi-band passive antenna. The result is a versatile, space-saving site solution that requires fewer boxes, accelerates 5G rollouts, and reduces site-related costs.
The AirScale Massive MIMO radios and the platform antenna products can be installed separately, enabling immediate and future flexibility. This allows for straightforward in-field upgrade paths in line with traffic growth, ensuring that network operators can adapt and evolve their infrastructure as 5G continues to expand and evolve.
