Introduction of MiFi (3G or 4G Hotspot)

Now lets have a brief introduction of MiFi (3G or 4G Hotspot). Wi-Fi is nearly everywhere we go these days, but we don’t want to rely on it for data connectivity (3G or 4G)—after all, there seems to be some law of physics that says it’s never there when the need it most. To solve this problem, keep a wireless hotspot all times, like the MiFi, which you can get on multiple carriers. Alternatively, if you’ve a jail-broken your iPhone, you can use MyWi together it, or with the Android phone with PDANet. Of course, togethering has its downsides, so be aware of those before you go that route—the Mi-Fi might be a better choice if you want to conserve battery or get the fastest internet possible.
