- Suppose we are unable to connect to the internet as no wi-fi source is available we have to connect to public network.
- It gives you access wherever you are able to use your mobile network.
- Usually some of them are equipped with antennae to enhance cellular reception.
FIg 1. SIERRA WIRELESS AIRCARD(EMBEDDED)
- We usually connect to a modem via a wireless router in order to receive data on your device.
- The modem acts as the gateway to the internet.
- So basically this aircard is the modem which is embedded into your wireless device such as laptop which acts as a gateway to the internet.
- As most users are aware of this they need to pay a bundle sum of money to renew the subscription plan every month from the activation of the data plan on the user’s device.
- This price is mostly fixed and when the allotted amount of data as per subscription plan is exhausted the user is charged extra for the extra amount of MB/GB(Network Data unit) usage.
- They enable users to have more hasslefree high speed network on their devices wherever they travel to.
- It can immediately access to another network without any delay.
- Based on cellular network availability wherever the mobile tower is present u can connect in those regions.
- Wireless radios require a wireless network(Hotspot or public network) in order to connect whereas an aircard does not.
NETWORKS AND VARYING SPEEDS:
- Obviously using an aircard on a 4g network will provide blazing speeds when compared to using an aircard on a 3g cellular network.
- However based on differences between cellular networks sometimes 3g cellular networks may provide more speed than 4g networks.
