Remote communication is mainstream now, and being able to connect to the internet anywhere and at any time has become an essential service for business and personal.
Wi-Fi hotspots offer fast and cheap access. Security must at all times be of paramount importance, which is why many mobile and laptop users have moved away from using Wi-Fi to 4G access services.
What is Wi-Fi?
"Wi-Fi doesn't stand for anything. It is not an acronym. There is no meaning." stated Phil Belanger, a member of the Wi-Fi Alliance. "We (the founding members of the Wireless Ethernet Compatibility Alliance, now called the Wi-Fi Alliance) hired Interbrand to come up with the name and logo that we could use for our interoperability seal and marketing efforts.'"
Wi-Fi is a standard connection provided by a wireless network. A wireless network is in turn provided by any other any other device that connects into another Internet access. That device then translates its own Internet connection into a Wi-Fi network that other devices can share.
Wi-Fi networks are typically small and have a limit on the numbers of users connecting. The network can be private, in which case you need to know a password to have access. Or, the network can be an open, public hotspot,allowing any device with Wi-Fi capabilities to log in. Turning on Wi-Fi means your device is looking for an existing network.
What is "G"?
G stands for generation - 4G means fourth generation.
Quora.com explains 4G this way Initiated in 2010, the fourth generation is an all IP based network system. Its purpose is to provide high speed, high quality and high capacity to users while improving security and lower the cost of voice and data services, multimedia and internet over IP./p>
The generations are ever-higher industry standards of speed, so an area with 4G service will always be faster than an area with 3G. Other factors of speed depend on the device being used. Older devices can't use the full power of an area with higher coverage. A 3G phone will work in an area with 4G coverage, but will only connect at 3G speeds, and likewise a 4G phone will work in an area with 3G, but only connect at 3G speeds.
Wi-Fi on a mobile device will usually use up more battery power than a 4G connection.
Cyber security company F-Secure says: "Public Wi-Fi simply wasn't built with 21st century security demands in mind. When you use public Wi-Fi without any added security measures, you leak data about yourself from your device."
The speed and convenience that 4G connections has meant their popularity has skyrocketed so using 4G securely is now a priority.
Technology has helped speeds move past what can be expected with an average Wi-Fi connection, making 4G the connection channel of choice for fast and secure internet access on the move.
Advances in mobile connectivity offer solid speeds depending on the carrier and the location, often better than can be expected with the average Wi-Fi connection, especially if you're trying to use a congested Wi-Fi hotspot.
The major benefit of 4G is that it is able to seamlessly handover, for voice and data to GSM, UMTS and CDMA2000 technologies from the previous different generations infrastructure.
