Abstract: A method for wireless communication in a reflective environment includes (a) receiving first wireless signals at a first antenna assembly at least partially via a first reflective environment, (b) generating a first electrical signal from a first antenna element of the first antenna assembly in response to the first wireless signals, the first antenna element having a first polarization, (c) generating a second electrical signal from a second antenna element of the first antenna assembly in response to the first wireless signals, the second antenna element having a second polarization different from the first polarization, (d) shifting phase of at least one of the first electrical signal and the second electrical signal, and (e) after shifting phase, combining at least the first electrical signal and the second electrical signal to generate a combined electrical signal.

Abstract: A method for distributed wireless encryption includes (a) establishing, at a first wireless access point (WAP), a first encrypted wireless communication link between the first WAP and a first device, (b) receiving, at the first WAP, an encrypted data packet from the first device via the first encrypted wireless communication link, and (c) forwarding the encrypted data packet from the first WAP to a first node within the first local area network (LAN), without decrypting the encrypted data packet.

Abstract: Facilitating backhaul between multiples access points (APs) using ducts or other bounded passageways within a building, dwelling, etc. is contemplated. The backhaul may be utilized to facilitate exchange of data obtained by the APs through fronthaul with one or more clients. The data exchanged between the APs through backhaul may be referred to as ducthauling.
