4G Wi-Fi connects you to the Internet faster than 3G technology. 3G, the third generation cell-phone network, carried enough speed for Internet access from mobile phones, using data. 4G networks span the U.S. from coast to coast, in hundreds of cities nationwide. It allows users to connect to the web wirelessly, using enabled devices such as e-readers, gaming systems, laptops, tablets and smartphones. Data is measured in gigabytes, which measures data storage capacity. Data is allotted per month, depending on your mobile plan. 4G is fast enough to support media-rich activity, such as streaming movies and music, and video conferencing. Carriers offer plans with different amounts of data allowed per month. Certain carriers also have a pay-as-you go option. Some mobile-phone carriers offer portable hotspots, which broadcasts 4G connectivity on the go. Some auto makers now include 4G Wi-Fi in new cars, with capacity to connect multiple devices.
3G is high-speed Internet. It’s fast enough to connect laptops, tablets, smartphones and more. 4G is newer and faster. It satisfied a growing appetite for data by mobile-device users. Mobile customers on a 3G signal can browse the web, post photos and videos to social media, and more. With 3G wireless Internet, users can access apps for GPS navigation, music streaming, TV and more. In areas where 4G isn’t available, mobile networks will connect users with a 3G signal if available. Both 4G and 3G are broadcast from radio towers. Mobile devices can be equipped to receive a 3G signal in addition to available Wi-Fi networks. Users with 3G-enabled devices pay for that access through a mobile-phone provider. It gives the user access to the Internet through 3G when Wi-Fi isn’t an option. Like 4G, 3G access can also come with the help of a portable hotspot a mobile-phone carrier can provide.
Mobile broadband has been around since the second generation cell-phone network
Users can access the 3G mobile broadband network through Internet sticks and pocket-Wi-Fi modems. These devices for Internet access are known as dongles. They’re also known as USB mobile broadband sticks, USB modems, or USB network adapters. The stick, for use in laptops and tablets, plugs into the USB port on an enabled device. Most can connect multiple devices with one stick or modem. Major cell-phone carriers offer a mobile broadband option, too. Sometimes they’re included at no cost when a customer signs up for service. 3G mobile broadband has enough strength for basic web activity, such as checking email, reading headlines and updating social media. A user might experience buffering if they try to stream movie and music services or participate in a video conference. Coverage works only in places where a user has mobile-phone reception.
The largest 4G mobile broadband networks can support as many as 20 devices on the same signal. Data used by all these devices from the same signal count against a prepaid data amount or a monthly allowance from your mobile plan. Some carriers offer as much as 30GB per month and about 12-15Mbps. Apps that require constant Internet connection, online gaming, and streaming video or music consume the most data of typical online activity. 4G plans cover most major U.S. cities and more of the nation than most 3G networks. The upgrade in the newest generation also brings more advanced authentication and security than 3G. 4G is also compatible with Virtual Private Networks (VPN), and often, a provider will furnish an extender cable with service. Customers can plug this extender cable into their device USB port and a USB modem for optimal signal strength.
