The differences between ISM protocol and other wireless protocols like Bluetooth, Wifi, Zigbee.

These protocols differ from their technical features and their applications.

For example, informatics networks involve a high volume and a high rate of data transfer. In this case, Bluetooth and Wifi networks are massively used for these applications but they require the main current because of their high level of consumption.

On the contrary, industrial applications like reporting of data sensors require a low rate of data transfer, but a high level of reliability. So, communicating on the ISM 868 MHz bands ensure an efficient data transfer and is adapted for applications which require a low rate of data transfer: it ensures a better reliability and a complete freedom.

The unlicensed ISM bands below 1GHz are widely used for various consumer and industrial applications where long range, system cost, and long battery life concerns are critical. Applications in these market segments are diverse and can include home automation, security, industrial control, remote sensing, automatic meter reading, toys, weather stations, among many other consumer applications.

The ISM band frequencies enable to have a compact radio bridge with a high range:

• In free space and with a ¼ wavelength antenna (i.e. only 8,6cm), the range is up to 800 m
• Radiofrequencies can go through out concrete walls
• he transmission is not disturbed by obstacles such as human bodies (this is the case for Wifi and Bluetooth technologies at 2,4 GHz)
• Interferences are rare because this frequency is only used for industrial, scientist and medical applications.

Due to excellent propagation characteristics at sub-GHz frequencies, greatly extended ranges can be obtained at much lower current consumptions than from to the 2.4GHz band solutions. In addition, these sub-GHz bands are free from microwave, WiFi and Bluetooth interference making links substantially more robust than their 2.4GHz counterpart solutions.

The Newsteo communication protocol is

• Optimized to function with a limited power in order to have a portable solutions powered by simple lithium batteries.
• Tough enough to endure industrial conditions.
