Expand Jump to a Section Compatibility How to Use MiFi Limitations and Issues You can use a MiFi device to create an ad hoc network that helps several devices share a data connection on a cellular network. MiFi devices include built-in modems and work as mobile hotspots or wireless routers. MiFi is the brand name for portable devices from Inseego Corp, which sold its mobile broadband MiFi business in 2016.

MiFi Compatibility

Inseego makes several models of MiFi devices. Some are only available from certain carriers, and some are global: MiFi 7730L Global Mobile Hotspot: A premium device that provides up to 24 hours of battery life on a single charge. It includes simultaneous dual-band Wi-Fi. Up to 15 Wi-Fi clients can connect simultaneously. MiFi 6630 Global Hotspot: Connects up to 15 devices to LTE cellular networks for up to 20 hours on a single charge. It includes a built-in power pack that charges external devices.MiFi 5510 3G/4G Intelligent Mobile Hotspot: Comes with a screen that displays the data usage, which is helpful to avoid overage fees. Up to 10 devices can connect simultaneously. The devices are small, some barely four inches wide. Wireless service providers such as Verizon and Sprint sell their own branded versions of MiFi.

How to Use MiFi

Connecting a MiFi device to a cellular network typically requires setting up or updating a service contract with your cellular service provider. A MiFi usually has its own data connection from the cellular service provider. Configuring local wireless support and connecting Wi-Fi devices to a MiFi is similar to connecting to a wireless router you may buy for your home.

MiFi Limitations and Issues

Connection speeds attainable through a MiFi are limited to the speed of the cellular network. Also, when several devices use the MiFi connection at the same time, speeds can drop because the MiFi shares the bandwidth of its cellular network connection among those connected devices. Portable hotspots like the MiFi require significant power to run. Depending on how many devices you connect and your usage, the battery life may or may not be sufficient for your needs. However, current MiFi models can provide a full day's worth of power to average users who connect intermittently before the device requires recharging. Monitor your MiFi usage. The convenience of connecting devices such as laptops, which often consume larger amounts of data than smartphones, can quickly use up data plan quotas. Was this page helpful?
