Engineering Contradiction Analysis
1Speed
If shorter wavelength frequency bands are used to provide faster broadband connections, then connection speed is improved, but signal reliability deteriorates due to increased susceptibility to blockages
Solution Approach 1:
The patent introduces reflective surfaces (such as buildings, vehicles, or dedicated reflectors) as intermediary elements to redirect high-frequency signals around blockages. The access point transmits signals toward reflective surfaces, which then redirect the signals to the user device, enabling reliable communication even when direct line-of-sight paths are blocked by obstacles like walls or terrain.
Solution Approach 2:
The patent utilizes three-dimensional spatial routing by directing signals along complex paths involving multiple reflections off surfaces at different angles and distances. Instead of relying solely on direct linear transmission, the system employs multi-dimensional signal propagation through reflective surfaces to overcome blockages and maintain signal reliability.
2Speed
If shorter wavelength frequency bands are used to provide faster broadband connections, then connection speed is improved, but ease of operation deteriorates due to narrower beams and positioning challenges
Solution Approach 1:
Reflective surfaces serve as intermediary elements that simplify signal positioning by providing predictable reflection paths. The access point can transmit signals toward these known reflective surfaces, which then redirect the signals to the user device, making the positioning process more manageable despite the narrow beams of high-frequency signals.
Solution Approach 2:
The system employs feedback mechanisms where the access point receives signal information from the user device and adjusts transmission parameters accordingly. This feedback loop enables dynamic adaptation of signal directions and reflection paths, simplifying the operation of narrow-beam high-frequency signals in varying environmental conditions.

AI summary
The technologies described herein are generally directed to using a reflective surface to reflect a signal from access point equipment to signal receiving equipment in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include receiving a request from access point equipment to establish a communications session between the access point equipment and a user equipment. The method can further include identifying a reflective surface to facilitate a connection between the user equipment and the access point equipment, resulting in reflected path information corresponding to a reflected path for the communications session. Finally, the method can include, in response to the request, communicating to the access point equipment, the reflected path information.
