FHSS vs WIFI

The first step of choosing a baby monitor just right for your needs.




At today market, video baby monitors are mainly divided into 2 types of data transmission, FHSS and WiFi. Knowing their characteristics and difference will surely help you to choose a correct baby monitor right for your needs.


FHSS (Frequency Hopping Spread Spectrum)


FHSS, or namely frequency hopping, is a proprietary transmission protocol. Developers create their own transmission protocol under the regulations from international authorities like CE and FCC. Therefore, baby monitor from different manufacturers or even different own models may not compatible to each other.

FHSS is operating at 2.4GHz scope (2,400 MHz - 2,483 MHz), same as WiFi. One different thing is, the operating channel is not static. It hops rapidly among different channels insides the scope. That’s why we called frequency hopping.

The bandwidth of each channel is usually ranged from 2 MHz to 4 MHz. It determines the transmission data size, the larger the bandwidth, more data can be transmitted in each packet. However, the larger the bandwidth, the lesser penetration power which may results in a shorter transmission range.


WiFi


A well known and most common wireless transmission protocol today. It is also working at 2.4GHz scope but with a static frequency channel. The bandwidth is comparatively wider and ranged from 20 MHz to 40 MHz depends on the type of 802.11 standards.
