Extended Long Range Wireless Packet Design for 2.4 GHz Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current long range (LR) wireless communication systems face limitations in data rate and coverage range due to the use of lower frequency bands like 2.4 GHz, resulting in latency and low throughput compared to higher frequency bands, and often suffer from uplink and downlink power imbalances.
Innovation Solution
The implementation of an extended long range (ELR) wireless packet design that uses a 2.4 GHz or higher frequency band with orthogonal frequency division (OFDM) communications, featuring boosted transmit power for preamble fields, additional repetitions, and a narrow bandwidth to enhance data rate and coverage range, while addressing power imbalances through specific power boosting and repetition strategies.

Engineering Contradiction Analysis
1Length of stationary object
If lower frequency bands like 2.4 GHz are used for long range wireless communication, then coverage range is improved, but data rate and throughput deteriorate
Solution Approach 1:
The patent changes the frequency parameter by introducing higher frequency bands (5 GHz and 6 GHz) alongside 2.4 GHz, enabling the system to operate at multiple frequencies. This allows the system to achieve both long range (using 2.4 GHz) and high data rate (using 5 GHz or 6 GHz) by selecting appropriate frequency bands for different transmission requirements.
2Length of stationary object
If lower frequency bands like 2.4 GHz are used for long range wireless communication, then coverage range is improved, but latency increases
Solution Approach 1:
The patent introduces multiple frequency bands (2.4 GHz, 5 GHz, 6 GHz) with different propagation characteristics. Higher frequency bands can be selected for transmissions where lower latency is critical, while 2.4 GHz is used for maximum range requirements, thereby reducing overall system latency through frequency band selection.
3Productivity
If higher frequency bands like 5 GHz or 6 GHz are used, then data rate is improved, but coverage range deteriorates
Solution Approach 1:
The patent implements frequency band selection based on transmission requirements. For long range communications, the system uses 2.4 GHz band; for high data rate requirements, it uses 5 GHz or 6 GHz band. This dynamic frequency selection resolves the contradiction by matching the frequency band to the specific communication goal.
4Productivity
If higher frequency bands like 5 GHz or 6 GHz are used, then data rate is improved, but power balance between uplink and downlink deteriorates
Solution Approach 1:
The patent introduces frequency band selection as a parameter change strategy. By allowing the system to operate at 2.4 GHz, 5 GHz, and 6 GHz bands, it can choose the appropriate band to achieve both high data rate and acceptable power balance, as different frequency bands have different propagation characteristics that affect uplink and downlink power requirements differently.

AI summary
This disclosure provides methods, components, devices and systems for extended long range wireless packet design. Some aspects more specifically relate to increasing a data rate, a coverage range, or both for extended long range (ELR) wireless communications systems by updating an ELR wireless packet design. A wireless communications device, such as a wireless station (STA), may transmit an ELR wireless packet to another wireless communications device, such as a wireless access point (AP), with updated preamble fields, boosted transmit power for one or more preamble fields, and/or additional repetitions for one or more preamble fields. Additionally, or alternatively, the wireless communications device may transmit an ELR wireless packet using a narrow bandwidth to increase coverage range for an ELR wireless communications system.
