What do these differences mean in reality?<\/h4>\n\n\n\n
    \n
  • WiFi 4 (The Basic):<\/strong>\u200b The baseline standard. It works on both 2.4GHz (longer range, slower) and 5GHz (shorter range, faster), but it struggles to handle many modern devices simultaneously.<\/li>\n\n\n\n
  • WiFi 5 (The Speed Booster):<\/strong>\u200b Focused purely on making the 5GHz band faster. It introduced wider channels and better modulation (256-QAM) to boost speeds, making it great for HD video streaming and gaming.<\/li>\n\n\n\n
  • WiFi 6 (The Capacity King):<\/strong>\u200b Instead of just focusing on speed, WiFi 6 focused on efficiency<\/strong>. It introduced OFDMA (allowing the router to talk to multiple devices at once) and Target Wake Time (saving battery on your phone). It is perfect for smart homes with dozens of connected devices.<\/li>\n\n\n\n
  • WiFi 7 (The Future Proof):<\/strong>\u200b A massive leap forward. It unlocks the new 6GHz band, doubles the channel width to 320MHz, and introduces MLO (Multi-Link Operation)<\/strong>, which allows devices to send data over multiple bands simultaneously. This results in ultra-low latency and massive speeds, designed for 8K streaming, VR\/AR, and cloud gaming.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
