Wireless connectivity tells a clear story of generational difference. The Redmi Note 14 Pro 5G supports Wi-Fi 6 (802.11ax) in addition to the older Wi-Fi 5 and Wi-Fi 4 standards that the Vivo Y39 5G is limited to. Wi-Fi 6 delivers higher throughput, better performance in congested environments, and improved efficiency — meaningful for users on modern routers in dense households or offices. The Redmi's cellular speeds reinforce this pattern: it posts a symmetrical 3270 Mbits/s on both upload and download, compared to the Y39's 2500 Mbits/s down and notably weaker 900 Mbits/s up. That upload gap matters for video calls, cloud backups, and live streaming. Bluetooth follows suit, with the Redmi on the newer 5.4 standard versus the Y39's 5.1, offering improved connection stability and efficiency.
Two feature-level differentiators are also worth noting. The Redmi Note 14 Pro includes an infrared (IR) blaster, which lets it function as a universal remote for TVs, air conditioners, and other appliances — a niche but genuinely useful convenience the Y39 lacks entirely. Everything else in this group — dual SIM, USB Type-C 2.0, NFC, fingerprint scanner, GPS, gyroscope, accelerometer, and Galileo support — is shared between both phones, reflecting a well-matched baseline of modern connectivity features.
Taken together, the Redmi Note 14 Pro 5G holds a clear edge in this group. Its Wi-Fi 6 support, faster and more balanced cellular speeds, newer Bluetooth version, and IR blaster all represent practical, everyday advantages over the Y39 5G's more modest connectivity profile.
