Benefits of technology

Effectively protects power amplifiers from corruption and damage by detecting and mitigating signal errors, ensuring reliable data transmission and reducing the risk of equipment damage in DAS networks.

Problems solved by technology

Unplugging the communications media (Fiber Optic Cable, Ethernet, Microwave Link, etc.) or abruptly cutting the cable can create unwanted spikes in the complex signals.
These spikes can be delivered to the power amplifier and subsequently damage the internal devices.
Any discrepancy between the two CRC codes will imply that the data has been corrupted with errors.

Embodiment Construction

[0015]A distributed antenna system (DAS) provides an efficient means of utilization of base station resources. The base station or base stations associated with a DAS can be located in a central location and / or facility commonly known as a base station hotel. The DAS network comprises one or more digital access units (DAUs) that function as the interface between the base stations and the digital remote units (DRUs). The DAUs can be collocated with the base stations. The DRUs can be daisy chained together and / or placed in a star configuration and provide coverage for a given geographical area. The DRUs are typically connected with the DAUs by employing a high-speed optical fiber link. This approach facilitates transport of the RF signals from the base stations to a remote location or area served by the DRUs.

[0016]An embodiment shown in FIG. 1 illustrates a basic DAS network architecture according to an embodiment of the present invention and provides an example of a data transport sc...

Abstract

A method of conditioning payload data includes providing a processor and receiving a packet comprising payload data, a first error code, and a second error code. The method also includes computing, using the processor, a first recalculated error code and determining a difference between the first error code and the first recalculated error code. The method further includes modifying the payload data in response to determining the difference.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 095,706, filed on Dec. 3, 2013; which claims priority to U.S. Provisional Patent Application No. 61 / 733,324, filed on Dec. 4, 2012. Each of these references is hereby incorporated by reference in its entirety for all purposes.BACKGROUND OF THE INVENTION[0002]Wireless and mobile network operators face the continuing challenge of building networks that effectively manage high data-traffic growth rates. Mobility and an increased level of multimedia content for end users requires end-to-end network adaptations that support both new services and the increased demand for broadband and flat-rate Internet access. One of the most difficult challenges faced by network operators is maximizing the capacity of their DAS networks while ensuring cost-effective DAS deployments and at the same time providing a very high degree of DAS remote unit availability.[0003]Despite the progr...
