5G Wireless Technology Essay

Linear Network Coding (LNC) computational complexity makes it unsuitable for practical use in devices that operate on battery power, such as mobile phones and wireless sensors. The triangular pattern based packet coding scheme is performed in two stages. First, redundant “0” bits are selectively added at the head and tail of each packet to make sure that all packets are of uniform bit length. The packets are then…

Even though VANET is considered as a type of MANET, it has its own particular features that make it different from MANET. These characteristics include: 1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m. 2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network…

Vertical Handover Abstract: In this era of technology, next generation wireless networks are very popular that allow users to connect to different radio access technologies such as UTMS, WiMax, GSM, etc. In such heterogeneous environment Vertical Handover is executed thus a user can switch among different radio access networks that makes whole process so complex. Vertical Handover algorithms require many parameters such as interference power, QoS, network conditions, terminal capabilities,…

is a visible light technology to achieve high speed wireless communication by using visible light to transfer data. It acquired this name due to its similarity to WI-FI which utilizes radio waves for transfer of data. WI-FI is great for extensive wireless coverage in buildings but has severe limitations for high density wireless information coverage in limited space and has radio waves interference issues; While Li-Fi greatly overcomes such restrictions. These two technologies can be well…

Visible Light Communication – Tomorrow’s Technology YASHODHA J K NITHYASHREE N Weir EnSci, Bengaluru Weir EnSci, Bengaluru yashodhajk@gmail.com Nithyashree0292@gmail.com Abstract-The Visible Light Communication (VLC) is an emerging technology, which provides distinct facilities such as fast data communication, secure data communication, high data rate wireless communication, etc. Instead of radio frequency, VLC uses light, to transfer data. The visible light spectrum is unlicensed…

characteristics of the wireless communication channel. The simplest model is the protocol model in which two nodes can communicate with each other iff they locate in each other’s communication range Rc. Further, in order to capture other disruptive physical characteristics of the wireless channel (e.g., the multiple path fading, and the interference, etc.) rather than only the diminishing effect of the transmission distance, the authors in [Gupta and Kumar 2000] modeled wireless channels…

frequency spectrum resource is utilized. The efficient use of spectrum is analyzed in terms of coverage area, capacity and reuse distance. OFDMA is a very potential multiple access technique, which will be the key technique for the next generation of wireless communications (4G). In this paper the QoS parameters of OFDMA i.e. spectral efficiency [Erlangs/MHz/m2], system capacity is estimated and also compared with the WCDMA. The other important parameters…

We are aiming to develop a device which is useful for both deaf and dump. We introduce a new device “SILENCE BREAKER”. It consist of a Camera, Micro Projector, Mobile computing device and a bluetooth headset. The synchronized action of all these components helps the dump and deaf for proper communication. The Silence Breaker recognizes the gestures of the dump and generates voice signal corresponding to it. In the case of deaf, the device captures the oral sounds and converts to gestures which…

Now, people are using technology to communicate with friends or families. Also, a type of technology that is used frequently is the Internet. The Internet allows people to connect with people and can gain facts that are essential for people to live. Nurse uses technology such as the Internet and wireless devices to communicate in their field. Also, it makes nurses life’s easier than tracking down a colleague to know what to do if something terrible happens such as someone falling of the bed.…

User connectivity will be controlled and authenticated through active directory. User devices will require and object to be created in active directory which will be used to authenticate the device using 802.1x. When a user device is connected to the network it will initially communicate on a VLAN will only be allowed to communicate with active directory. Then once the device has been authenticated it will place the device on the appropriate VLAN that it will operate on. Any device that has not…
