Publication number: 20210084538Abstract: Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.Type: ApplicationFiled: November 24, 2020Publication date: March 18, 2021Inventors: Steven Paul Papa, Rajesh Kumar Mishra, Kaitki Agarwal, Sridhar Donepudi, Sumit Garg, Kartik Shashikant Raval, Prashanth Rao
