With so many WiFi devices like smartphones,
tablets, notebooks and sometimes even TVs, it is useful to have a WiFi
data card. Here are the five best options you have
since different devices like tablets, PCs and even TVs come with
WiFi it makes sense to have a pocket router or WiFi hotspot dongle.
We have selected a few of such routers which we think offer good features and value for money.
Huawei E560
Huawei is the leader in the data card business with more than 65 per
cent market share worldwide. Priced at Rs 4,500, E560 is the most
expensive offering from Huawei. But in terms of usability the device
justifies its price. This open market router accepts a
SIM from any operator; offers speeds up to 7.2 Mbps and allows sharing the WiFi hotspot with up to five devices.

There is an Oled display on the device that shows the signal status,
connection type, number of WiFi users connected, battery status, total
volume transferred, up time and number of
SMSs received.

The inbuilt 1500 mAh battery of the Huawei E560 powers it for five
hours of use and 280 hours of standby. Huawei also claims 15 per cent
better signal strength as compared to rivals. The Huawei E560 supports
WiFi b/g/n, which is the highest possible standard.
Micromax 400R (MiFi) Datacard
Micromax 400R is quite similar to Huawei E560 but is cheaper. The
dongle doesn't have a screen; instead there are four LED indicators for
power, a WiFi/WPS indicator, a network type indicator and a signal
strength indicator, which give very limited information compared to
Huawei.

The battery provides four hours of usage on full recharge, an hour
less than the Huawei router. However, it is priced at just Rs 2,700,
which is Rs 1,300 less than the Huawei E560. It provides a maximum
3G speed of 7.2 Mbps. It supports a 16 GB micro SD card and WiFi b/g.
