Communications contribute to non-ICT carbon emissions. As the world has moved from 2G and 3G to 4G, and now 5G, mobile services have expanded from voice calls and text messages to
In addition, when mobile traffic is low, some frequency bands of base stations can be temporarily disabled. This conserves energy without compromising network performance or user experience. 5G enables energy savings in other industries.

Two different frequency ranges are defined for 5G communication: FR1 (410 MHz–7.125 GHz) and FR2 (24.250–52.6 GHz). 5G and LTE networks share some common frequency bands due to the fact that 5G will be compatible with LTE during the early stage of deployment .
This position paper presents Huawei's insights and recommendations on 5G spectrum and regulations impacting the allocation of frequency bands. The ITU-R IMT-2020 (5G) Vision1 includes three usage scenarios: Enhanced Mobile Broadband (eMBB), Massive Machine Type Communications (mMTC) and Ultra-Reliable and Low Latency Communications (URLLC).
High frequencies (above 6 GHz) will also play an important role for 5G in meeting the ITU-R IMT-2020 vision: at least 800 MHz of contiguous spectrum per 5G network should be available to meet the 5G requirement of very high capacity, especially in hotspot areas as well as for fixed broadband fibre-like connectivity ("WTTx").
The 24.25–29.5 GHz and the 37-43.5 GHz bands are the most promising for 5G deployments requiring coordinated efforts from all regions and countries to reach a global harmonisation for 5G use. 3GPP has already identified initial bands for the 5G NR as well as band combinations for LTE/NR uplink co-existence and dual connectivity.
These factors may delay 5G NR ecosystem development for high frequency bands. Huawei encourages regulators to address these issues to allow the ecosystem over high frequency bands to be ready from 2020. The L-band (1427-1518 MHz) is another 5G candidate band that has the potential to be allocated to mobile in most countries in the world.
Apart from certain advantages, 5G poses several challenges from an antenna design perspective for both sub-6 GHz and millimeter (mm)-wave bands, and hence it is crucial to investigate the limitations and design considerations for such systems.
