Description of Wi-Fi & Li-Fi

Facing trouble with Wi-Fi signals is common in our daily routine life, we need best coverage based on Wi-Fi signals on every room in our house. Achieving this , usually we set channels of the router to overcome interference , upgrade firmware , often we get this by changing router position , using access points in repeater mode or extenders , having antennas or rely on single vendor solution to gain best possible support in maintain Wi-Fi signal coverage .

Just around a year before we were in practice to use Wi-Fi booster techniques for getting best coverage. But today, we do this through clever LED lamps and beamforming Wi-Fi routing capabilities.

Extending Wi-Fi signals through an LED lightbulb is interesting ; these LED Bulbs have built-inWi-Fi repeater , we can screw it as normal lamp (A19 bulb standard) and can connect with the home network through a downloadableapp (iOS or Android), works best as Wi-Fi extender , even when it is dim.

Sengled is the Practical implementation on LED Wi-Fi,technical specifications are as follows:

  • LED A19, BR30, and PAR38 integrated with Wi-Fi repeater.
  • Boosting signals connect wirelessly to home router to extend the Wi-Fi signals.
  • Supports 802.11 b/g/n @ 2.4GHz with 2×2 MIMO antenna array
  • 35 meters of range within line of sight (LoS)
  • Security modes are 64/128 bit WPA-PSK/WPS2-PSK, WPA/WPA2
  • Encryption modes are WEP64/WEP128/TKIP/AES
  • iOS/Android app for controlling Wi-Fi and light

Li-Fi

Wi-Fi works by emitting out radio waves in all 4 directions around the residential area or workplace of a wireless router. Whenever we use wireless device, such as a tab or smartphone, it senses the wireless radio waves, provides connectivity with nearby located wireless router to connect with the Internet or intranet. The concept behind Li-Fi is almost same and uses similar 802.11 protocols but instead of wireless radio waves which are sent in all directions, LED lights used to deliver the better down link demand at high speed to send data all around due to low interference and high intensity optical output. It is basically a complementary technology including benefits such as energy efficiency and safety of a wireless system.
