A number of elements have an effect on the efficiency of a residential Wi-Fi community, together with the placement of the router and the presence of a microwave oven. Wi-Fi can also be impacted by units which are related to the router. Nevertheless, an older system that employs the 802.11b protocol can sluggish your Wi-Fi community.
Wi-Fi transmits information through radio waves with a 2.4 GHz or 5 GHz frequency. This frequency dictates the variety of waves per second that cross by means of a hard and fast location. Additionally, Wi-Fi protocols outline distinct modulation strategies, leading to various quantities of knowledge transmitted by Wi-Fi:
802.11 utilized direct sequence unfold spectrum (DSSS) or frequency hopping spectrum (FHSS) to transmit information at 2 Mbps.
This protocol was the primary improve to the 802.11 specs. It elevated the theoretical bandwidth to 54 Mbps and supplied a transmission frequency of 5 GHz. This improve in efficiency resulted from the utilization of a better frequency and a brand new modulation method often called Orthogonal Frequency Division Multiplexing (OFDM).
Utilizing the two.4GHz band, 802.11b tried to enhance the info charges provided by 802.11 by utilizing the two.4GHz band. This protocol provided a knowledge transport pace of 11 Mbit/s. Nevertheless, modulation strategies have remained the identical, whereas DSSS has been enhanced; 802.11n provided a knowledge fee of 600 Mbps through OFDM.
The protocol employs single-user MIMO to perform these speeds, which allows the router to transmit a number of information streams to the identical person utilizing distinct antennas. Moreover, the protocol helps dual-band Wi-Fi, enabling information transmission on each 2.4 GHz and 5 GHz.
Newer applied sciences, corresponding to Wi-Fi 6, use the 802.11ax protocol and might obtain speeds of as much as 2.4 Gbit/s along with the protocols listed above. Wi-Fi 6 employs multi-user MIMO to perform these speeds, rising channel bandwidth.
Why do 802.11b units decelerate my Wi-Fi community?
Consequently, distinct protocols make use of distinct information transmission modulation strategies. On account of this, a tool that solely helps the 802.11b protocol can not comprehend 802.11n-transmitted information.
Nevertheless, it ought to operate if an 802.11b system is related to an 802.11n router. The router employs the 802.11b protocol to speak with such a tool. Consequently, the speed of knowledge transmission over Wi-Fi decreases.
As well as, the info switch fee doesn’t change when the router is related to a tool with 802.11n as a result of the router makes use of faster protocols when connecting to a tool that helps new protocols.
Nevertheless, if the router doesn’t help MIMO, it will probably solely transmit information to 1 system concurrently. Due to this fact, if a tool on the community makes use of an antiquated protocol, the router will take longer to connect with different units, slowing down the community.
In consequence, the community efficiency decreases when the 802.11b protocol is used as a result of information transmission takes longer.
You probably have a dual-band Wi-Fi community and your units help each outdated and new protocols, you possibly can join your older units to the two.4 GHz community and your newer units to the 5 GHz community. It will forestall older units from interfering with newer, quicker ones.
