MiFi is a brand of wireless router that acts as a mobile Wi-Fi hotspot device.

In many countries, including The United States, Canada, and Mexico, Inseego Corp. (previously known as Novatel Wireless)[1] owns a registered trademark on the "MiFi" brand name; in the United Kingdom, mobile operator Hutchison 3G owns the "MiFi" trademark. Novatel Wireless has never offered an official explanation for the origin of the name "MiFi"; it has been suggested that it is short for "My Wi-Fi".[2]

A MiFi device can be connected to a cellular network and provide Internet access for up to fifteen devices. Inseego Corp. introduced the first MiFi device in the United States in May .[3] In the UK, Hutchison 3G's "MiFi" is a similar product from Huawei with the same name.[4][5]

• May be connected to a computer via a micro-USB connection, though doing so disables the Wi-Fi networking, converting the device into a traditional single-client modem. (However, CNET described a tweak to charge the device over USB while maintaining its functionality.

4G mobile hotspot devices

The Las Vegas Consumer Electronics Show saw the introduction of two new 4G-capable MiFi devices from Novatel:

Both devices maintain backward compatibility with existing 3G networks. Other features include:[16]

5G mobile hotspot devices

In November , Vodafone Qatar and Inseego Corp. together launched the Gulf region&#;s first commercially available 5G mobile hotspot, 5G MiFi M.[18]

• Connects up to 16 devices simultaneously (15 by Wi-Fi plus one by USB or Ethernet)
• Power optimization features Quick Charge technology and high-capacity battery

Non-Novatel wireless devices

A number of providers other than Novatel provide personal hotspot, "MiFi"-like services:

Alternatives

Mobile phones with an Internet connection can often be turned into Wi-Fi hotspots using a process called "tethering", which is similar to using dedicated MiFi devices.

The following families have built-in features to create Wi-Fi access point:

For other phones there are third-party applications to allow this:

Security issues

In January , two major security holes were discovered with the Novatel MiFi which, if properly exploited, could allow a malicious user to obtain the device's current GPS location and security keys. If the malicious user were physically close enough to use the device's Wi-Fi signal, this could give access to the MiFi's 3G connection as well as any other connected devices.[44] Novatel responded that a security patch would be available in February .[45]

The popularity of MiFi devices can also be problematic for corporate network security. Corporations generally expect to control on-site Internet access: many use firewalls to reduce the risk of malware, and some enforce restrictions aimed at employee productivity. Personal mobile hotspots may provide a "back door" by which employees can circumvent these precautions.[46]

Recall information

In May , the MiFi was recalled in Canada by Bell Mobility and Rogers Communications.[47] In two documented cases, the difficulty of opening the MiFi battery compartment had caused customers to use levels of force that caused physical damage to the batteries, which then overheated. Novatel replaced the recalled units with ones that have an easier-to-open battery compartment.

Radio interference at trade shows

At two major trade shows in &#; Google's first public demo of Google TV and the iPhone 4 demonstrations at the Apple Worldwide Developers Conference &#; keynote presentations using available Wi-Fi connectivity were disrupted by network unreliability. The problem was traced to massive radio interference, caused by the popularity of MiFi and similar devices for "liveblogging" from the trade show floor. Apple CEO Steve Jobs said that 570 different Wi-Fi networks ("several hundred" being MiFi's[48]) had been operating simultaneously in the Apple exhibit hall.[49][50]

MiFi is wireless internet you can get on the go. A MiFi device is a small router or hotspot that typically works over a cellular connection, using network data to get you a Wi-Fi connection for laptops, tablets, and other devices.

The term &#;MiFi&#; originated with the MiFi series of mobile hotspots that were first manufactured by Novatel in the late s. But MiFi has since become a catch-all word for any kind of hotspot or portable router that provides Wi-Fi for connected devices. It&#;s kind of like how all tissues are Kleenex.

We do tons of research on hotspots at HighSpeedInternet.com, so we&#;ve put together a quick and handy guide to what MiFi is, how it works, and how you can wield the power of MiFi to your own advantage.
