Recently, the concept of mobile broadband was taken ahead by the innovation of the mobile Wi-Fi modems. It is otherwise known as MiFi modem. It is a combination of mobile broadband and Wi-Fi technology. A typical mobile broadband modem provides internet access to one computer at a time, while the MiFi device can provide access to multiple devices like laptops, I-phone, Smart phone, I-pad, I-pod, etc, at the same time. The device receives the broadband signal using a SIM card and transmits them using wireless 802.11b/g standards. Any device enabled with a wireless card internally or externally can gain access to the device. The device is powered using a rechargeable lithium battery which holds good for 5 hours of internet browsing. Since there isn’t any wire connected to the device at all, it’s completely independent and can be used from anywhere. The devices can be charged either using a USB power adapter or can be connected to the USB port of a computer.
The plan of upgrading the mobile networks to the 4G standards can definitely make mobile broadband powerful as the coverage and speed provided will be extremely higher than the current 2G and 3G standards. Analysts say that the minimum speed offered will be 100Mbps and the maximum can reach up to 1Gbps. Also enabling wireless 802.11n network access in the MiFi modems will allow file sharing between the devices connected in the network. Future MiFi modem which can access 4G networks and provide wireless 802.11b/g/n access will serve as a perfect home networking device.
