Single RF Transceiver Time-Division Multiplexing for LCIB Protocol Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-Cost Internet Base Stations (LCIBs) require additional hardware to support multiple simultaneous wireless communication protocols, increasing costs and complexity.
Innovation Solution
An LCIB is designed to provide wireless service on a single RF carrier using a first wireless-communication protocol and then switch to a second protocol, using a single RF transceiver, allowing alternating service provision without the need for hardware to support two simultaneous carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an LCIB uses a single RF transceiver to provide wireless service on a single RF carrier using one protocol at a time, then hardware cost and complexity are reduced, but the ability to provide multiple protocols simultaneously is lost
Solution Approach 1:
The patent applies dynamics by enabling the LCIB to dynamically switch between different wireless communication protocols (e.g., CDMA1x, EV-DO, HSPA) on the same RF carrier. The system transitions from a static single-protocol configuration to a dynamic multi-protocol capability, allowing the base station to adapt its operating protocol based on network conditions and customer requirements without changing hardware components.
Solution Approach 2:
The patent implements universality by designing the LCIB to perform multiple functions through a single RF transceiver capable of supporting multiple wireless protocols. Instead of requiring separate dedicated hardware for each protocol, the system makes the single transceiver universal, enabling it to handle CDMA1x, EV-DO, HSPA and other protocols interchangeably on the same carrier frequency.
2Adaptability or versatility
If an LCIB supports multiple wireless communication protocols on a single RF carrier, then protocol versatility is improved, but hardware cost increases due to requiring additional RF transceivers
Solution Approach 1:
The patent implements universality by designing the LCIB to perform multiple functions through a single RF transceiver capable of supporting multiple wireless protocols. Instead of requiring separate dedicated hardware for each protocol, the system makes the single transceiver universal, enabling it to handle CDMA1x, EV-DO, HSPA and other protocols interchangeably on the same carrier frequency.
Solution Approach 2:
The patent applies merging by combining multiple protocol support capabilities into a single RF transceiver unit. Rather than having separate transceivers for different protocols, the system merges the functionality of multiple specialized hardware components into one multi-functional device, thereby reducing overall hardware cost while maintaining protocol versatility.
3Productivity
If an LCIB provides service on multiple RF carriers simultaneously, then service coverage and capacity are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent applies periodic action by enabling the LCIB to time-division multiplex different wireless protocols on the same RF carrier. The system switches between protocols in periodic cycles, allowing multiple protocols to share the same physical resources without requiring simultaneous hardware support for all protocols. This temporal separation reduces hardware complexity while maintaining service capacity.

AI summary
Methods and systems are provided for providing wireless service using multiple protocols on a single radio-frequency (RF) carrier. According to an embodiment, a low-cost Internet base station (LCIB) provides wireless service on an RF carrier using a first wireless-communication protocol and provides wireless service on the RF carrier using a second wireless-communication protocol, where providing wireless service on the RF carrier using the first wireless-communication protocol and providing wireless service on the RF carrier using the second wireless-communication protocol occur at different times. The LCIB may alternate between providing wireless service using the first wireless-communication protocol and providing wireless service using the second wireless-communication protocol.
