Embodiment Construction

[0016] A microcontroller unit (MCU) can be defined as a host microcontroller or programmable logic with non-volatile program memory. According to the teachings of the present invention, the tasks of the MCU can be taken over with minimal addition of logic implemented as RF transceiver logic. By eliminating the MCU, energy consumption is reduced, for example, the MCU can consume 30% to 50% of the total energy in a typical wireless node. Standalone RF radios can operate faster without the additional burden of being controlled by the MCU. All of these factors benefit battery life (for example, battery life can be doubled).

[0017] A stand-alone RF wireless device can also be used as a stand-alone repeater to forward received messages to extend the range of a wireless network, and is a cost-sensitive application such as a stand-alone repeater. Leaf nodes (eg, the largest number of nodes in a WSN) of a wireless sensor network (WSN) are also cost sensitive applications. The leaf...

Abstract

The present invention discloses an inexpensive and low power requirement RF wireless device with data acquisition capability that can be used for simple applications such as a stand-alone data repeater or a stand-alone data acquisition node without the need for a The host microcontroller unit MCU or programmable logic of the wireless device.

Description

[0001] Related patent applications [0002] This application claim was filed in 2011 by Michael Simmons, Yifeng Yang, Steven R. Bible and Péter Szilveszter Kovács Priority to commonly-owned U.S. Provisional Patent Application No. 61 / 492,535, filed June 2, 2009, entitled "Standalone Radio Frequency Transceiver Having Data Acquisition Capabilities"; Said US Provisional Patent Application is hereby incorporated herein by reference for all purposes. technical field [0003] The present invention relates to radio frequency repeaters and wireless nodes, and more particularly to stand-alone radio frequency wireless repeaters and data acquisition nodes. Background technique [0004] A typical wireless node includes a radio frequency (RF) transceiver and a host microcontroller unit (MCU) or programmable logic to control the RF transceiver. Requiring an MCU or programmable logic in conjunction with an RF transceiver increases the cost of manufacturing device board or die space and ...
