“5G small cells complement macro cells, boosting network capacity and extending coverage in dense areas where signals are weak or unavailable. They also allow network operators to derive more value from their existing spectrums by exploiting them more efficiently,” said Fei Liu, 5G and mobile network infrastructure industry analyst at ABI Research. “Compared to the previous generation small cells, 5G small cells face more challenges in design and performance. 5G small cells need to be smaller and lighter while supporting larger bandwidths such as 100MHz and 200MHz. With 5G, there is a wider range of deployment scenarios, forcing vendors to provide comprehensive solutions to support every need.”

ABI predicts that the fast-growing data traffic forces mobile network operators to upgrade their network capacity. With a limited number of new macro cell sites available and a limited number of 5G spectrums, the most practical approach is the dense deployment of 5G small cells, albeit at a high cost.
Massive MIMO (mMIMO) macro cells have so far fulfilled 5G capacity demands, but these may not likely be adequate, making small cells more critical. By 2027, there will be 13 million outdoor 5G small cell deployments. 5G small cell deployments will overtake 4G in 2028.

In addition to distributed antenna systems and Wi-Fi networks, small cells for 5G networks are increasingly enabling richer radio coverage, thus becoming more common in consumer and enterprise markets. A study from ABI Research has found they are now vital in enabling mobile network operators to make good on their promises to subscribers that 5G will provide higher capacity, faster speed, higher energy efficiency, lower RAN latency, and create massive connectivity.

An “explosion” of 5G data traffic is expected to drive outdoor 5G small cell deployments to 13 million by 2027, and it will eventually overtake 4G in 2028, according to analyst ABI Research. It has forecast that global 5G mobile data traffic will grow at a staggering compound annual growth rate of 63% (CAGR), reaching 1,676 exabytes (one exabyte equals one billion gigabytes) in 2026. The company forecasts a particular acceleration in 5G small cell rollouts around 2025 when 5G capacity offered by massive MIMO “becomes insufficient”. According to ABI Research, dense deployments of 5G small cells are “the most practical approach”, albeit coming at a high cost, because of the “limited number of new macro cell sites available and a limited number of 5G spectrums”.

Outdoor small cell deployments will start to ramp around 2025 when Massive MIMO macro cells can no longer fulfill 5G capacity demands, ABI Research predicted.
The research company also warned C-Band capacity would start to run out without additional spectrum or small cell densification. It expects 5G mobile data traffic to reach 1,676 Exabytes in 2026, a CAGR of 63 per cent.
ABI Research expects there to be 13 million outdoor 5G small cell deployments by 2027, with the sum to eclipse 4G a year later.
Fei Liu, 5G and mobile network infrastructure industry analyst noted 5G small cells “complement macro cells, boosting network capacity and extending coverage in dense areas where signals are weak or unavailable”.

5G networks are reaching scale in many developed nations, delivering an exceptional user experience and higher data rates to consumers and enterprise users. 5G has proven to be 90% more energy-efficient than 4G in terms of energy consumption per unit of traffic. However, it is still expected to cause a dramatic increase in energy consumption due to the implementation of Massive Multiple-Input, Multiple-Output (mMIMO), and the level of network densification. According to global technology intelligence firm, ABI Research, a 5G base station requires 3X more energy to provide the same coverage as a 4G network, burdening network operators with high energy costs and Capital Expenditure (CAPEX). However, hardware optimization will lead to significant improvement in power consumption, i.e. the new generation of chipsets will offer typical energy savings of 30% to 70%.

Telecoms operators need to embrace new approaches to optimise the hardware they use if they are to fulfil a goal of significantly decreasing their energy consumption and associated costs, as power-hungry 5G networks reach scale in developed markets.
This is the main point made in a new report from research company ABI Research, which suggests if operators act wisely and optimise the hardware used in their systems, this will bring about a decline in power consumption of up to 70% and, therefore, will reduce energy bills.
Despite 5G networks being 90% more energy efficient than 4G in terms of power consumption per unit of traffic, they are very likely to cause “a dramatic increase in energy consumption” due to the implementation of massive MIMO and the level of network densification.

Operators have an energy consumption problem on their hands that’s both exacerbated and diminished by 5G, according to ABI Research.
“Despite 5G consuming less power than 4G per unit of traffic, the overall energy consumption is still much higher, driven by more power-thirsty radios and network densification,” ABI Research analyst Fei Liu wrote in a new report.
The energy-efficiency gains and subsequent increases are astounding. Whereas 5G infrastructure can be 90% more energy efficient than 4G on a per bit basis, a typical 5G base station also requires three times more energy to provide the same coverage as a 4G network, according to Liu.
“5G energy consumption depends on radio configuration, hardware, and traffic load, and over 70% of the consumed energy is in the radio access network (RAN). A 5G RAN consumes up to 2.7 kilowatts of power with 64T64R massive MIMO configurations in a typical condition, whereas an LTE radio consumes about 0.8 kilowatts,” she wrote.
