The use of 433 and 868 MHz
433 and 868 MHz enable C&T to communicate with numerous wireless devices from a broad range of different brands. Since the communication standards are relatively old there are many devices which use it, especially the more affordable devices. 868 MHz features several security devices. Note that these are just a few the relatively well-known brands. There are TONS of wireless devices out there which use these technologies – from robot lawn mowers to fireplaces and TV mounts and much, much more!


433MHz essentially is a frequency band that is used for communication in home appliances among other things. It has become quite popular as most countries in the world have freely allowed communication. This means devices may use the band without any restrictions or license fees. The only limitation is transmitting power, but the power limit is plenty for wireless transmission around the house. 868MHz is also free to use but requires your device to keep communication to a minimum (it is only allowed to transmit a signal more than 1% of the time). This makes 868MHz more suited for alarm/security signals since signals have a higher probability of getting through without being disrupted by other devices. This is a key difference compared to the unrestricted 433 bands, where everyone can just ‘shout’ (i.e. transmit data) and thereby disturb other signals.


How 433Mhz and 868Mhz communication works
Communication on 433/868 works with radio frequency waves on those frequencies. These waves are transmitted and received by a radio transceiver with an antenna. On these bands, a couple of communication methods can be used, called radio modulations.


The most commonly used radio modulations on 433 and 868MHz are ASK (Amplitude-Shift Key) and variations of FSK (Frequency-Shift Key) like BFSK or GFSK. Basically, they define how data is transmitted: ASK uses differences in Amplitude (transmitting power) to create waves/data transmission. FSK uses slight differences in frequency instead. Nearly all 433/868 devices support just a single radio modulation. Often for controllers, this is ASK modulation for 433 and FSK modulation for 868 MHz. However, in order to enable our antenna to work with as many devices as possible, we have made sure that both radio modulations are supported on both technologies.

ISM antenna Solution 


ISM bands were originally allocated for the industrial, scientific and medical purpose. Typical applications include a large range of machine-to-machine RF systems. 
C&T RF Antennas Inc offers easy-to-implement standard antennas for all the most important ISM bands.
C&T RF Antennas Inc' antennas for ISM applications offer very small size without compromising RF performance. This combined with the inherent immunity of ceramic antennas to other radiators and the hand effect makes them extremely desirable solutions for small hand-held devices.
The helical antennas offer extreme performance for free-space applications.

Lora (Long Range) is a patented digital wireless data communication technology developed by Cycleo of Grenoble, France, and acquired by Semtech in 2012. Lora uses license-free sub-gigahertz radio frequency bands like 169 MHz, 433 MHz, 868 MHz (Europe) and 915 MHz (North America). Lora enables very-long-range transmissions (more than 10 km in rural areas) with low power consumption. The technology is presented in two parts — Lora, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.
Lora and LoRaWAN permit inexpensive, long-range connectivity for the Internet of Things (IoT) devices in rural, remote and offshore industries. They are typically used in mining, natural resource management, renewable energy, transcontinental logistics, and supply chain management.
