Advancements in 4.5G technology, improved SNR (signal to noise ratio) and link reliability and expected launch of 5G in 2019 are primary factors that are expected to boost the market during the forecast period. There are already strategies and projects in place for smart cities, self-driving cars are on the horizon, social media has grown at a vast scale, and Internet of Things (IoT) devices and systems are taking off. Significant adoption of 4G LTE in all these arenas is generating tremendous amounts of data and the expected launch of 5G is poised to connect billions of devices in the coming years.
The basic idea behind Massive MIMO framework is the use of multiple antenna arrays at base station to reduce error rate and increase efficiency which results in the overall system becoming more complex and large than traditional systems. The complex structure makes it difficult to diagnose the problems occurring in the Massive MIMO system. Furthermore, as a result of use of huge number of antenna systems and complexity, Massive MIMO systems are far more expensive than traditional antenna systems.
In terms of technology, the Massive MIMO technology market is segmented into LTE advanced, LTE advanced pro, and 5G. In 2017, LTE advanced segment accumulated the highest share of the market and is projected to witness significant CAGR over the forecast period. LTE advanced supports data rate up to 1 Gbps and in turn improves the customer experience. Also, 5G cellular networks are expected to be commercially deployed by the end of 2019. However, some of the global leading network providers are upgrading their existing infrastructure with 5G-ready network systems which can support both existing and 5G networks.
