5G connectivity transmitting data at 10Gbps brings new challenges to the design of broadband products. The development of new radio devices for next generation of communications will require high reliability, low latency, exceptional coverage, and reasonable cost, all while improving efficiency to maintain battery life. As the network grows, Altair simulation is the key to developing new products.

5G Radio Channel Models

Altair Feko™ wave propagation models have been extended to account for the higher-frequency bands and specific characteristics of 5G. This includes defining the electrical properties for material transmission and reflection, in addition to atmospheric absorption characteristics.

A wideband propagation measurement campaign at 73 GHz in New York has been used to verify that the Altair ray-tracing model is able to correctly predict the propagation characteristics.

5G Radio Networks

Ultra-dense networks will be required in urban areas to meet high data volumes. Feko® ray-tracing can analyze large numbers of base stations simultaneously, including new designs such as massive multiple-input and multiple-output (MIMO) antenna arrays on base stations. It has also enabled the virtual testing of elevation spread of departure (ESD) angles in city environments to evaluate network performance.

5G Antenna Design and Placement

Feko is widely used for the design of radio and TV, wireless, cellular, communication, remote keyless entry, tire-pressure monitoring, satellite positioning, radars, RFID, and other antennas. Feko’s method of moments (MoM) solver is used for antenna design. Model decomposition is possible with accelerated full-wave methods like multi-level fast multipole method (MLFMM), or asymptotic methods like physical optics (PO), ray-launching geometrical optics (RL-GO) or uniform theory of diffraction (UTD).
