Genvej til trådløse netværk i det åbne ISM-bånd

Microchip udvider firmaets såkaldte MiWi udviklingsmiljø til design af trådløse stjerne og mesh netværksprodukter, der benytter 2,4 GHz, 868 MHz og 915 MHz ISM frekvensbåndene (in english).

Microchip announces the expansion of its MiWi Development Environment (DE) which provides a complete ecosystem for designing star and mesh wireless networking products. 

The MiWi DE comprises Microchip’s free, proprietary MiWi P2P, MiWi and MiWi PRO star and mesh networking protocol stacks; the 8-bit Wireless Development Kit (WDK) and 2.4 GHz, 868 MHz and 915 MHz ZENA Wireless Adapters; as well as the multi-purpose Wireless Development Studio (WDS) with cross-platform support for Linux, Mac OS and Windows operating systems. 


The MiWi DE simplifies the development of ISM-band wireless networking applications for the home and industrial automation, wireless sensor monitoring and control, and smart energy markets.

As a single, seamless development environment, with three interchangeable protocol stacks and three interchangeable wireless PICtail daughter boards, the expanded development environment provides a flexible, cost-effective platform which helps customers to reduce risk and accelerate time to market when adding low-power wireless connectivity to embedded microcontroller applications.

The new MiWi PRO mesh-networking protocol is ideal for design engineers needing to create medium to large wireless systems.  It supports up to 64 hops and 8,000 nodes in an integrated mesh-network topology. 

The Wireless Development Studio allows the quick, easy development of wireless applications based on the MiWi protocols. It features a MiWi protocol sniffer for monitoring, debugging and gathering information, and a configurator with a graphical user interface that enables customisation and configuration of wireless networks. 

Two new hardware tools also simplify wireless application development:  The ZENA Wireless Adapter is a portable, multi-function development tool which, when paired with the Wireless Development Studio, can be used for sniffing, probing and testing, or for configuration as a node on the network. 

The 8-bit Wireless Development Kit provides eXtreme Low Power PIC microcontroller users with an easy-to-use platform for developing, evaluating and testing low-power, cost-effective embedded wireless connectivity.  It features a pair of wireless PICtail daughter boards, two battery-friendly 8-bit XLP PIC MCU development boards and the ability to add additional nodes to create a larger wireless network.

As part of the expanded MiWi DE, the following tools are available for free download today:  The MiWi PRO protocol stack can be downloaded from www.microchip.com/miwi; and the Wireless Development Studio from www.microchip.com/wds. 

Low-cost development tools are also available immediately:  The 8-bit Wireless Development Kit – 2.4 GHz MRF24J40 (DM182015-1), priced at $299 and the ZENA Wireless Adapter – 2.4 GHz MRF24J40 (AC182015-1), priced at $49.  ZENA adapters for 868 MHz and 915 MHz wireless applications are expected to be available in the fourth quarter of 2011.
