What is the WLAN phone?
The Locals Local Area (WLAN) wireless phone (WLAN) concerns a telephone device that has the ability to connect to a home or office network wireless network using a local router. Cafe, airports and many municipalities also offer free access WLAN or hotspots. If available, you can use the WLAN phone to surf on the web or mail check. The WLAN mobile phone usually offers access to the Internet through a cellular broadband service known as Wwan. WWAN connections are more expensive than WLAN, but they have the advantage of providing mobile access limited only according to the cellular plan coverage. The mobile phone can have both WLAN and WWAN chips.
WWAN or mobile broadband has a clear and critical advantage over WLAN: WWAN provides Internet access. Second generation technology (2G) retreated 3G and 4G networks, with the competition management of constantly developing, even faster tastes. In some caseH can meet or even exceed WLAN for speed, the cellular broadband connection can meet different factors. Specific carriers and plans, mobile phone hardware, regional mobile technologies, weather and even loading networks appear into the power of a broadband connection to a mobile connection.
The only constant of WWAN technology is that it is not free or cheap. A typical user buys internet minutes together with a mobile phone plan and increases the total cost of the monthly cell service. Alternatively, you can buy WWAN access to pay-as-you-go-basis, starting with 24-hour additions. Once it is signed in, it is possible to sail over the Internet while driving in a taxi, sitting in a park or waiting in client offices and providing a cell carrier directly or through roaming contracts.
The advantage of the WLAN phone is that one can optionallyBypass the expensive mobile broadband service, instead using free hotspots. At home, in the office, and when the mobile approach is not planted, wwan with WLAN can save money by maintaining wwan minutes to a minimum.
Ti with an unlimited WWAN plan can still find WLAN on hand. For example, WLAN can be more convenient in regions with older, slower mobile networks; where the carrier imposes roaming fees; Or where there is no coverage at all. It may also happen that the cell network overloads regionally, as if a local disaster or some other event causes many people to use their mobile phones simultaneously. In such cases, WLAN will still allow the user to connect to the Internet via any local hotspot.
