NYU Wireless sees trouble ahead for 5G unless 3GPP adopts new channel modeling methods


Researchers at NYU Wireless are warning the cellular industry that it needs to change the "alpha-beta-gamma" (ABG) model used in the past and start using simpler, more accurate models for predicting signal coverage for frequencies above 6 GHz.

A new study by Theodore (Ted) S. Rappaport, the Ernst Weber/David Lee professor of electrical engineering at NYU Tandon School of Engineering and founding director of NYU Wireless, suggests that the three-parameter ABG model used in the past by 3GPP for predicting signal coverage might spell trouble at frequencies above 6 GHz.
