What is MiFi?

MiFi is a new innovation which is expected to dominate the mobile broadband market in the coming years. It’s a compact but powerful device that allows multiple wireless enabled electronic gadgets to access the internet. It receives and transmits a broadband connection wirelessly without any external power source.

How MiFi works?

The working of MiFi is very simple. It is an integration of Mobile Broadband and WiFi.

Mobile Broadband + WiFi = MiFi (Mobile WiFi)

WiFi Hotspot: A WiFi-hotspot is a place where a user can get wireless access to the internet either for free or at a cheaper price. A device called “Wireless Router” is connected to the ISP (Internet Service Provider). The signal received from the ISP is transmitted wirelessly for a certain distance, which can be accessed by any wireless enabled device.

MiFi allows users to create a wireless hotspot within their home or office. The device used for creating this simple wireless home network is known as a MiFi modem or MiFi router.

The device will have a SIM card which is capable of receiving the signals from a 3G network based on the availability and coverage in the area. The received signal is transmitted wirelessly to a certain range and creates a wireless zone. Any wireless enabled electronic device within the range can access the wireless network.

This device does not require an external power source; instead it uses a rechargeable battery. The device can be secured using a password, thus restricting unauthorized usage.

MiFi providers- UK

3 MiFi Review


The design of the 3 MiFi device seem to be more compact and stylish. It is little bigger than a mobile broadband dongle. Much of the space is occupied by the battery and the display.

Power Supply

The lithium battery provided in the kit holds good for 5+ hours of browsing. The battery can be charged using the standard charger provided with the kit. Also we can use a USB cable and connect it to the USB port of the computer for charging. Initial 12 hours of power supply can make the battery perform better.

Display and Control Switches

The whole device can be controlled using three switches. These switches might be a little difficult for beginners to use, because the device responds better only if it is used in a sequence.

The display shows the complete status of the device. Since the device is working on a battery the lights switches off automatically on standby. The user has to press the power button every time to view the lights again.


The SIM card in the MiFi device will access only the 3 mobile network. 3 mobile coverage is available in almost all parts of UK. But the metros would receive a better signal than the rural.


3 mobile promises a download speed of 7.2Mbps and upload speed of 2Mbps. On an average the download speeds stays around 2.5Mbps and upload speeds stays around 1Mbps.

The 3 MiFi modem is able to transmit its Wi-Fi signals for around 25 meters in a open space, while the signals can get interrupted by thick walls.

3 Mi-Fi supports only the wireless standards 802.11 B and G. But it has not yet reached the maximum speed range of G. Unlike Wi-Fi it does not support the N standard which allows file transfer between devices.

Other Features

  1. The external micro SD slot supports up to 32 GB, that’s a lot as a storage device.
  2. The device can provide access to a wide variety of devices from I-pods to play stations.
  3. First time configuration of the device would be essential so users can change the password for their Mi-Fi device.
  4. Improved speed ranges would allow us to get the maximum use of it.
