What is a single/dual-band wireless router and what is the difference between them?
Brief Introduction of Single Frequency Router
Single-frequency router only works in 2.4 GHz band. Generally, wireless terminals support this band, but the 2.4 GHz band has a large interference, which may affect the wireless rate and stability.
Brief Introduction of Dual-Frequency Router
Dual-band routers work in 2.4 GHz and 5 GHz bands, with less interference in 5 GHz band. Nowadays, more and more mobile phones, notebooks and other terminals on the market support 5 GHz band (if all terminals in the home do not support 5 GHz band, single-band routers are recommended; if there are terminals supporting 5 GHz band, dual-band routers are recommended, wireless. Internet speed experience is better.
1. Communication Standards
Dual frequency is 802.11n and 802.11ac, while single frequency is only 802.11n, so two WIFIs can be searched in the case of digital hard support 802.11ac.
2. Working frequency band
The frequency range of single-frequency router is 2.400-2.4835 GHz, which is referred to as the radio frequency band (5150 MHz-5825 MHz) used in 2.4 GHz dual-band.
3. Transmission speed
The actual transmission rate of 802.11n Wireless router is between 75Mbps and 150Mbps.
The entry-level speed of 5G Wi-Fi is 433 Mbps.
The difference between the two
The difference between single-band and dual-band wireless routers is mainly focused on signal range, transmission power, stability and anti-jamming.
(1) Compared with single frequency, dual frequency has wider signal coverage. Dual-band wireless router is more suitable for complex environment of house structure.
(2) Dual-frequency wireless routers are more stable than single-frequency wireless devices.
(3) Dual-frequency wireless router has strong anti-interference.
