SMA BT548 Bluetooth 5.4 USB Adapter

The SMA BT548 is a USB Bluetooth 5.4 adapter that adds wireless connectivity to desktop and laptop computers lacking built-in Bluetooth. It includes a 5dBi external antenna to extend the wireless signal up to 150 metres. The compact black dongle weighs 18 grams and measures 7.08 inches in length. It is intended for users who need to connect Bluetooth peripherals such as headsets, speakers, mice or keyboards to a Windows PC.

Who this suits and who should look elsewhere

This adapter suits Windows 8.1, 10 or 11 users who want plug-and-play setup and the ability to run up to seven Bluetooth devices simultaneously. Two BT548 units can also be paired directly with each other. Buyers using Windows 7 must download a driver first. The device does not work with Mac OS, Linux, Windows 8, XP, Vista, TVs, game consoles or car stereos.

Bluetooth 5.4 with 150-metre range

The single specification that decides fit is the Bluetooth 5.4 standard combined with a claimed 150-metre line-of-sight range from the 5dBi antenna. Maximum throughput is 3.0 megabits per second. If your environment needs that reach and you use a supported Windows version, this adapter meets the requirement; otherwise a shorter-range or differently supported adapter may be more appropriate.

Questions about this item

Does the 5 dBi antenna on the BT548 ever need to be replaced or realigned?

The 5 dBi antenna is built into the adapter and has no moving parts, so it does not require replacement or realignment under normal use.

What limits how many devices the BT548 can keep connected at once?

The adapter supports up to 7 simultaneous Bluetooth connections; that device count is the first limit reached during sustained multi-device use.

How warm does the BT548 get and does it draw much power when left plugged in all day?

The dongle is powered entirely from the USB port and runs cool during continuous operation; no external power or active cooling is needed.
