WebJan 1, 2015 · DSSS is a very useful technology with the following advantages: System collocation. Noise and interference immunity. Multipath immunity. Security purpose. … WebNov 7, 2007 · In DSSS, the overhead comes in the form of the spreading codes that are sent instead of the raw user data. This causes a DSSS system to transfer a higher volume of data than would be the case with just the raw data, leading to increased power consumption. ... Although DSSS and FHSS schemes employed by WiFi/ZigBee and Bluetooth …
WebA DSSS receiver cannot decode a FHSS transmission, and vice versa. One spread spectrum method is nothing but interference to a receiver using another spread spectrum method. The probability of a collision between Wi-Fi using DSSS and Bluetooth using FHSS is about 27%. If this unintentional blocking is sufficiently strong such that either the …
