Here group of stations belonging to an AP Infrastructure mode is setup by APs (Access Points) or routers. adhoc mode and infrastructure mode.Īdhoc mode is used by small number of mobile users and it does not require AP or router. WLAN network can be implemeted in two ways i.e. diffused, directed and directed point-to-point. Infrared transmission uses infrared light to carry information and it has three types viz. Refer DSSS vs FHSS for difference between FHSS and DSSS. FHSS (Frequency Hopping SS) and DSSS (Direct Sequence SS). In spread spectrum (SS) transmission, two modulation schemes are employed viz. The transmission technologies used in WLAN are spread spectrum and infrared. Now-a-days WLAN components are cheaper and hence it is widely used in home, enterprise and commercial public areas. Initially WLAN hardware was expensive and they were used only in certain scenarios where cabling was very difficult or impossible
2.4 vs 5 ghz mac#
Several WLAN versions define PHY (Physical) Layer and MAC (Medium Access Control) layer with distinct features such as QoS, Security, data rates etc. WLAN allows users to move around in selected area while they are still connected to the internet. It works similar to traditional LAN except it has wireless interface.
2.4 vs 5 ghz series#
Wireless Local Area Networks follow IEEE 802.11 series of standards. WLAN is wireless in nature and uses ISM band with three frequency ranges viz. WLAN (Wireless LAN) has been developed to overcome cabling difficulties observed in cabled LAN. This page compares 2.4 GHz WiFi vs 5 GHz WiFi and mentions difference between 2.4 GHz WiFi and 5 GHz WiFi with respect to speed, range, advantages, Difference between 2.4 GHz WiFi and 5 GHz WiFi | 2.4 GHz vs 5 GHz
