WWAN : WWAN (Wireless Wide Area Network) is a WAN (Wide Area Network) and the only thing is that the connectivity is wireless. It provides regional, nationwide and global wireless coverage. Where Wide Area Network can be wired or wireless the Wireless Wide Area Network connections are completely wireless. In our day to day life we are using the Wireless Wide Area Network of different sizes and depending on it delivery of telephonic calls, Web pages and streaming video, data sharing occurs.
WLAN (Wireless Local Area Network) differs from WWAN (Wireless Wide Area Network) technology wise for example when WLAN uses WiFi to connect and transfer data, WWAN uses telecommunication cellular network technologies such as 2G, 3G, 4G LTE, and 5G to transfer data.
WWAN not only always refers to a wide area rather a closed area with large geographic coverage is also considered as WWAN. For example a MANET (Mobile ad hoc networks) with nodes on buildings and towers or planes. A Low Power and low bit rate Wireless Wide Area Network (LPWAN) is also considered as WWAN. For example transmission of small packets of information between things in case of IoT (Internet of Things) implemented applications.
A general example of WWAN which we use in our daily life is a laptop installed with WWAN card establishes a secure and fastest connection and brings us to online so that we do our work from anywhere.
The below figure illustrates the wireless connection to Wide Area Network.
In the above figure, several wireless devices are configured with the WLAN (Wireless Local Area Network) served by the Router-A and Router-B is a wireless router which connects to Router-A through ethernet and connected to the WAN (Wide Area Network) wirelessly flashed with DD-WRT.
Families of WWAN :
The main three families of WWAN technologies include
- CDMA One/CDMA2000
Characteristics of WWAN :
- Reduced transmission speed as compared to physical connection.
- It is based on IEEE 802.16 standards.
- On increase of distance, decrease of throughput occurs and vice versa.
- Getting faster due to Gigabit-Class LTE.
Advantages of WWAN :
- Global wireless coverage
- Flexible with cloud management, deploying and relocating
- Better security than WLAN
- Diverse, cost effective backup for data applications.
- Quick deployment for new applications.
Disadvantages of WWAN :
- Replacement of lost WWAN may be costly.
- To maintain the reliable network connectivity.
- To build a cost effective solution is a challenge.
- Decreased throughput during large coverage area.
Application of Wireless Wide Area Network (WWAN):
1.Mobile correspondence: WWAN is normally utilized for portable correspondence, for example, voice calls, text informing, and web access. This can be especially helpful for individuals who need to remain associated while progressing, like business voyagers or telecommuters.
2.Fleet administration: WWAN can be utilized for armada the board, like following the area of vehicles, checking their presentation, and advancing their courses. This can assist organizations with decreasing fuel costs, increment productivity, and further develop client support.
3.Public security: WWAN can be utilized for public wellbeing, like empowering people on call for speak with one another during crises, and giving constant reports on the area of episodes. This can assist with further developing reaction times, diminish setbacks, and improve generally security.
4.Smart framework: WWAN can be utilized for shrewd network applications, for example, observing the exhibition of force stations, anticipating power interest, and overseeing energy dispersion. This can assist with working on the unwavering quality and productivity of energy conveyance, lessen expenses, and increment environmentally friendly power mix.
5.Environmental checking: WWAN can be utilized for natural observing, like estimating air quality, water quality, and atmospheric conditions. This information can be utilized to illuminate strategy choices, work on natural administration, and safeguard general wellbeing.
Generally, WWAN has various applications that can help different ventures and work on our regular routines. By giving remote network over a huge topographical region, WWAN can empower portable correspondence, armada the executives, public wellbeing, savvy lattice, ecological observing, and different applications that can improve proficiency, security, and supportability.
