antenna5G Americas, the industry trade association and voice of 5G and LTE for the Americas, has published a white paper that explores current trends in technology and spectrum enhancements for advanced antenna systems (AASs) that will improve 5G capabilities in data speeds, coverage, and improved user experiences.

5G will deliver up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. It can support a 100x increase in traffic capacity and network efficiency, as well as deliver more instantaneous access with a 10x decrease in network latency over 4G.

The new report, Advanced Antenna Systems for 5G, identifies how AAS will be commercialized, provides technical details into the increasing complexity of wireless antenna systems, and  illustrates how they are central to the development and deployment of 5G networks.

Specifically, the report provides considerations on how:

  • Improvements in beamforming and beam management (beam switching, recovery and refinement) techniques increase coverage and capacity across more control and broadcast channels compared to LTE, with radio of up to 64 or more transceiver and antenna elements
  • Massive MIMO adds even more capacity without adding more antenna elements, due to increasing degrees of freedom an antenna array has available to modify a transmitted signal – even for multiple users and antennas
  • Advances in using millimeter wave (mmWave) spectrum bands improves with fully integrated radio arrays that can include more than 100 transceiver and antenna elements
  • Use of spectrum below 6 GHz and in the mmWave range allow for significant improved coverage and capacity not possible through previous radio techniques
  • Different deployment scenarios can be based on network locations, services and use cases
The new antenna technologies will work with both standalone and non-standalone versions of 5G New Radio (NR).  However, the emerging complexity of the 5G NRs require operators and equipment manufacturers to manage a toolbox of passive and active radio solutions in spectrum bands below 6 GHz. In deploying AAS, operators will need to consider several factors, including performance versus cost, Electro-Magnetic Field (EMF) considerations and deployment constraints.

In addition to high-band spectrum, existing low- and mid-band spectrum will be essential to supporting 5G NR deployments. Initially, 5G NR will be deployed primarily in Time Division Duplex (TDD) bands, as well as in mmWave and sub-3 GHz Frequency Division Duplex (FDD) bands, based on network operator spectrum portfolios. When optimally deployed, 5G peak throughput speeds could provide up to eight concurrent streams at 20 Gbits/sec downlinks and four concurrent streams of 10 Gbits/sec uplinks.
