Divers. Blogs | Identify RF Remote Control. Overview - Typical RF Remote Control PCB Layout A typical RF remote control's PCB is comprised of many electronic components, such as SAW resonator which controls the transmitting frequency and encoder IC which encodes the transmitting data. The typical inner photo of RF remote control is listed as follows. Identify Operating Frequency There are two types of RF remote controls based on operating frequency controlling circuit, one is the fixed frequency model, while the other one is the adjustable frequency model. Fixed frequency model usually uses SAW (Surface Acoustic Wave) resonators to stabilize transmitting frequency, and is easier for operating frequency identification, while adjustable frequency model uses LC circuit, center frequency change is done using adjustable capacitor or adjustable inductor, and the operating frequency can be detected by spectrum or oscilloscope.
The detailed comparisons between fixed frequency model and adjustable frequency model are listed as follows.

Wavenis Wireless Technology is a 2-way Wireless connectivity platform dedicated to serving M2M applications. The main requirements in today's data-centric M2M industry are quite different from broadband and hi-speed Internet connections, and generally focus on providing ways to transmit small amounts of data wirelessly on a regular but non-permanent basis. Many M2M solutions are installed in places where access to electricity is not an option, so ultra-low-power consumption is a key feature for wireless M2M technologies, often with a requirement to provide multi-year operation in battery-powered devices such as utility meters and social alarms.
Furthermore, a high link budget is required to provide acceptably long-range connections in a variety of dense urban environments as well as widespread rural areas. Wavenis was created as a proprietary technology by Coronis Systems in 2001. In 2008, an initiative was undertaken to propagate the technology as an industry standard. Benefits[edit] Sigfox : One network, A billion dreams. DASH7. International standard[edit] DASH7 is based on the ISO/IEC 18000-7 open standard for the license-free 433 MHz ISM band air interface for wireless communications. 433 MHz is available for use worldwide, except certain countries where it is considered a restricted or licensed band such as India and Japan.
The wireless networking technology was originally created for military use and has been re-purposed for mainly commercial applications in place of proprietary protocols like ZigBee or Z-Wave. History[edit] In March 2009, the DASH7 Alliance, a non-profit industry consortium to promote interoperability among DASH7-compliant devices, was announced, and as of July 2010 has more than fifty participants in twenty-three countries.
Similar to what the WiFi Alliance does for IEEE 802.11, the the DASH7 Alliance is doing for the ISO 18000-7 standard for wireless sensor networking. In July 2013, the DASH7 Alliance announced the Dash7 Alliance Protocol Draft 0.2. Technical summary[edit] 433.92 MHz[edit]
