</a>RF" title="RF">RF" title="RF">RF-SNAP無線網狀網絡解決方案是采用Synapse公司基于Freescale的MC13224V收發器平臺的SM700 RF引擎.這種無線網絡模塊采用帶大容量片上存儲器的ARM7 32位處理器,并集成了12位ADC,工作頻率2400 - 2483.5MHz,輸出功率高達100mW,16個RF通路,戶外LOS距離達1.5英里,而TWR-RF-SNAP無線網狀網絡模塊可單獨使用,也可和Tower System一起使用.本文介紹了Synapse公司的SM700 RF引擎主要特性和指標,方框圖以及RF無線網狀網絡模塊TWR-RF-SNAP主要特性,方框圖和電路圖.

Synapse raises the bar on integrated performance with its SM700 RF Engine® based on the Freescale™ MC13224V transceiver platform. This wireless network module uses an ARM7 32-bit processor with large on-chip memory and integrated 12-bit ADCs.

And like all RF Engines from Synapse, the Model SM700 comes with SNAP® already loaded and ready to perform right out of the box. SNAP is Synapse’s award-winning, mesh network operating system that provides wireless connectivity for Internet-to-machine and machine-to-machine communications.

With 96K RAM of memory, large applications can bring intelligence to the very edge of the network for local operations. These applications can be uploaded over-the-air… even mesh hopping across the network to reach its destination. And because of the large memory in the SM700, the core SNAP operating system can also be upgraded over-the-air and leaves your network in place and intact.

Very little board space is needed for this RF Engine (25mm x 36mm). Even the antenna is integrated to further reduce system size and cost. What comes in a small package however is big on capabilities. The SM700 can achieve a range of over 1.5 miles and deliver an output of up to +20dBm. For applications requiring battery power, the Model SM700 can perform at power consumption levels as low as 12 μA.

RF無線網狀網絡模塊TWR-RF-SNAP

The Wireless Mesh Networking Tower Board (TWR-RF-SNAP) is a peripheral Tower System Module. The TWR-RF-SNAP provides wireless mesh networking via the FCC Certified Synapse Wireless SM700 RF Engine. The SM700 is based on the Freescale MC13224 chip which combines a 32-bit ARM7 MCU with an IEEE 802.15.4 radio transceiver.

The TWR-RF-SNAP module can function standalone or within the Tower System. As part of the Tower System, the TWR-RF-SNAP can interface with Tower System controller modules via SPI and can access available Tower System peripheral modules using UART or I2C. The TWR-RF-SNAP also includes a General Purpose Tower Plug-in (TWRPI) socket allowing direct access to a selection of sensor plug-ins via I2C.

A SN132 USB Dongle is also included with the TWR-RF-SNAP. The USB Dongle features the RF100 RF Engine based on a Freescale MC9S08 MCU and the Freescale MC13191 radio. The USB dongle provides a communication portal to a host computer via USB.

The TWR-RF-SNAP can be accessed in Synapse’s Portal IDE using either the on-board USB or wirelessly using the included RF100 USB Dongle.
