General Linn DS/DSM/HIB Wifi

The Wifi module used with the Linn DS/DSM/HUB supports IEEE 802.11a/b/g/n/ac PSK/CCMP 1-CH

this supports both 2.4G & 5G communications.

Wifi History

2.4G

This was the first Wifi defined in 1997, 802.11b, generally used with 11, or 13 channels depending on your country. Each channel could each supply a data rate of 11MBit/s .

This data rate was then expanded to 54MBit/s in 2003, with the 802.11g. However, this still used 2.4G and instead of using 1channel to communicate it now uses 3-channels to communicate.This reduced your number of usable channels as other device communicating on a channel next door would now encroach into your channel(s).

This means that 2.4G band can have a lot of noise and interference. Coupled with fact that this same frequncy is used by DECT phones, Microwave ovens, Baby mointors, Taxi Radio, Bluetooth.... These can inject a lot if noise and interfere with Wifi streaming link to the Linn DS/DSM/HUB.

5G

A newer standard, 802.11n, allows usage of both 2.4G and 5G to give an even bigger data rate of up to 600Mbit/s.

As standards improve the 802.11ac that the Linn DSM/Series3 supports is a data rato of up to 1,300MBit/s.

'5GHz is a much cleaner radio space with a lot less interence compare with 2.4G. The only negative is a slightly reduced range.

Some Wireless-Access-Points, WAPs and Router allow you to setup a SSID,
