Bluetooth, Wi-Fi and a "2.4 GHz wireless" receiver all transmit in the same slice of spectrum, so the label on a mouse or keyboard box names a protocol rather than a frequency. For desk peripherals the real choice is between two of them. A maker's own 2.4 GHz receiver can report movement 1,000 or even 8,000 times a second and belongs on a gaming PC. Bluetooth needs no dongle and suits a laptop or tablet. Wi-Fi is the connection for the printer and the robot vacuum.
Three names for one band
The Bluetooth SIG puts Bluetooth between 2.402 and 2.480 GHz, where it hops across dozens of narrow channels. A 2.4 GHz Wi-Fi network sits in the same band. "2.4 GHz wireless" on a peripheral means the maker's own protocol through a small USB receiver, which Logitech calls Lightspeed on its gaming mice and Razer calls HyperSpeed.
What separates them is who controls the two ends. With a receiver, the maker writes the firmware on both sides of the link and can schedule the radio as tightly as it likes. With Bluetooth, the mouse has to work with whatever Bluetooth chip, driver and operating system the computer has, and it gets the timing the Bluetooth specification allows.
The labels overlap more than the boxes admit. Logitech's Logi Bolt receiver, the dongle for its office range, is built on Bluetooth Low Energy, and Logitech says it enforces Security Mode 1 Level 4, the strictest LE security level. An MX Master 3S can connect through Bolt or straight to the computer's Bluetooth, and both paths are Bluetooth LE. What the receiver adds is Logitech's control over both ends. Logitech claims up to eight times lower latency than competing wireless protocols in crowded offices and rates the range at 33 feet.
Report rate and the Bluetooth ceiling
Bluetooth Low Energy carries a mouse's movement in scheduled connection events. Until Bluetooth Core 6.2, the shortest gap the specification allowed between events was 7.5 ms, so a Bluetooth mouse could deliver new movement at most about 133 times a second.
The Razer Viper V3 Pro and Logitech's G PRO X Superlight 2 both list 8,000 Hz wireless polling, a report every 0.125 ms. Even the common gaming figure of 1,000 Hz is more than seven times the old Bluetooth ceiling.
The Bluetooth SIG published Core 6.2 on November 4, 2025, and its Shorter Connection Intervals feature cuts the minimum gap to 375 µs, naming high-performance HID devices, the class that includes mice and keyboards, as the target. That is roughly 2,667 chances a second. The SIG's condition is that both ends support it, which for a mouse means the mouse, the computer's Bluetooth chip and the operating system. Until a maker rates a mouse's Bluetooth mode above the old ceiling and names the computers that reach it, treat Bluetooth as the office mode.
Every report wakes the radio, which is why a gaming mouse's 8,000 Hz mode is rated in hours while office mice on Bluetooth Low Energy are rated in months.
Where Wi-Fi fits on a desk
Wi-Fi connects a device to a network and, through the router, to the internet. A mouse or keyboard talks to one computer a few feet away, and sending each movement through a router would add a hop and a network login that a peripheral has no use for.
A printer receives whole documents over Wi-Fi, and a robot vacuum uploads maps and takes commands from a phone app. Those devices can share the band with your mouse. Roborock's help pages, for example, say its robots join only 2.4 GHz networks, a choice it explains by the band's better reach through walls.
Interference from the computer itself
On many desks the noisiest 2.4 GHz source is a USB 3 port. Intel measured it in an April 2012 white paper. An external USB 3.0 hard drive raised the noise floor in the 2.4 GHz band by nearly 20 dB, and a wireless mouse whose receiver sat in the same notebook worked at 2 feet but lagged at 3 feet and beyond. The lag was the same whether the drive was writing data or idle, and a USB 3.0 flash drive caused it too.
One of the fixes Intel tested was moving the receiver to the far side of the laptop on a USB 2.0 extension cable. If a receiver mouse stutters only when a fast drive or dock is plugged in, move the receiver away from that port first, or put it on an extension cable near the mouse. Switching to Bluetooth is no cure, since Intel saw a similar effect on Bluetooth radios.
Which connection to use
Take the receiver for games. A 2.4 GHz mouse on a 1,000 Hz or faster link updates several times as often as Bluetooth allowed until version 6.2, and the maker tunes both ends of it.
A laptop or tablet carried between rooms is better served by Bluetooth, which leaves the ports free. The MX Anywhere 3S connects over Bluetooth and ships without a receiver, so there is none to lose. Logitech says it also works with a Logi Bolt receiver.
A wireless keyboard often carries both radios, which removes the choice. The Keychron K2 HE has a cable, a 2.4 GHz receiver and Bluetooth for up to three devices, so the receiver can stay in the gaming PC while Bluetooth handles a tablet. Leave Wi-Fi to the printer and the robot vacuum.
