Wireless Network Access Manager Dynamic Band Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network devices cannot selectively access the most appropriate frequency band based on the type of service or characteristics of the local wireless network, leading to suboptimal performance.
Innovation Solution
An apparatus and method that include an access manager to request access to a wireless network based on specific service set identifiers (SSIDs) and a wireless network access module to search for and access the desired SSID, with the ability to download and compare access policies to ensure alignment with the current network settings, allowing for dynamic frequency band selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-band device accesses an arbitrary frequency band, then the device can connect to wireless networks, but the device cannot select the most appropriate frequency band based on service requirements
Solution Approach 1:
The patent implements dynamic frequency band selection by enabling the access manager to continuously monitor network conditions, service requirements, and policy updates, then adaptively switch between 2.4 GHz and 5 GHz bands. This dynamic adaptation allows the device to optimize performance based on real-time conditions rather than using static band selection.
Solution Approach 2:
The system employs feedback mechanisms where the access manager receives information about network quality, service performance, and policy requirements, then uses this feedback to make informed decisions about frequency band selection. The policy download module also provides feedback loops by continuously updating access policies based on network conditions.
2Reliability
If the device continuously monitors and compares access policies, then the device can maintain optimal network access, but the device consumes more processing resources and time
Solution Approach 1:
The patent implements preliminary action by having the policy download module proactively fetch and store access policies before they are needed for decision-making. The access manager prepares multiple frequency band options in advance based on predicted service requirements, reducing the time needed for real-time policy processing and comparison.

AI summary
An apparatus for accessing a wireless network includes an access manager configured to request access to a wireless network according to a wireless network access condition including at least one desired service set identifier (SSID); and a wireless network access module configured to search for at least one wireless network corresponding to the at least one desired SSID, and access the searched at least one wireless network.
