Compact 4G LTE USB hotspot

The MIRO UF1 is a portable USB 2.0 adapter that adds 4G LTE connectivity and a Wi-Fi hotspot to laptops or desktops. It accepts a mini-SIM card for mobile data and a microSD card up to 128GB for local storage. Travellers and remote workers can share a single mobile connection with up to 10 devices without installing drivers.

Thermals noise and power draw

The device draws power directly from the USB 2.0 port and requires no external supply. An internal antenna handles both LTE and 2.4GHz Wi-Fi signals. Two LEDs indicate network signal strength and hotspot activity. No fan or active cooling is present, so operation is silent.

Upgrade from tethering or single-slot dongles

It replaces phone tethering and single-function dongles by combining a 150Mbps downlink modem, a 40MHz 802.11b/g/n hotspot, and microSD file access in one unit. The jump is worth it when you need simultaneous connections for multiple gadgets and local storage without draining a phone battery. Not suited for users who require 5GHz Wi-Fi, higher LTE categories, or Ethernet ports.

Questions about this item

How do I install the UF1 and which step do people often miss?

Plug the USB 2.0 type-A connector into a powered port, insert an active mini-SIM, then wait for the network-signal LED to turn solid before enabling the Wi-Fi hotspot — many users skip the LED check and wonder why no SSID appears.

What maintenance or replacement will the UF1 need later?

The internal 2.4 GHz antennas and ASR1803L chipset have no user-serviceable parts; only the mini-SIM or microSD card (up to 128 GB) may be swapped when you change carrier or need more storage.

What limit appears first during sustained heavy use?

The LTE downlink caps at 150 Mbps and the Wi-Fi hotspot shares that over 802.11 b/g/n at 40 MHz, so throughput drops once combined client demand exceeds the cellular pipe.
