Advantages And Disadvantages Of Li-Fi

If you were implementing a low-cost wireless network that had to cover a very large area and support only a few users, the use of 802.11g technology would be a very good option. 11g technology operates at the 2.4Ghz range which allows for access points to provide signals up to 300 feet. The 2.4GHz signal also has lower rates of signal loss from obstructions. This means that a fewer number of AP's would need to be purchased for complete are coverage. Also, by providing throughput of up 54Mbps it could easily support bandwidth needs of multiple users who require minimal bandwidth. This would be the case of a warehouse or large department store where the applications would not place major demands on network resources.

These technologies bring the network closer to mobile users and improve spectral efficiency (SE) per unit arena (i.e capacity). Due to lower power and smaller physical size, pico/ femto/ relay cells can also be deployed to eliminate coverage holes and relay cells can be used in backhaul, where wire line backhaul is unavailable or not economical [150]-[152]. The heterogeneous deployment of LTE networks comprising of conventional Macro cell base stations overlaid with LPNs. The often random and unplanned location of these access points can cause severe interference problems especially for cell edge users. This problem was typically addressed by coordinating base-station transmissions to minimize interference. Figure 2.10 shows a heterogeneous

idea that they believe may aid in the process of having Wi-Fi wherever one may go. As well as

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

In this field trip, I am trying to find out the latest development of Information Technology and how these technologies affect our daily lives. Get to know about these technologies, how is it going to improve our lives in the further. This exhibition is about the next generation nationwide broadband network (Next Gen NBN). We get to learnt how Next Gen NBN improved Information Technology, as it offers broadband speeds of up to 1 Gigabit per second. With such high speed, more informations can be transferred in one second. This exhibition tell us about how Next Gen NBN improve our lives, work, Interaction and learning. In this essay I am going to discuss three technologies which I think

Known to many as Wi-Fi, its actual name is “Wireless Fidelity.” Wi-Fi is considered to be what correlates to wireless networking technology of which allows computers amongst other devices to communicate over a wireless signal. The designation 802.11

Many technologies that came to be discovered in the last half century were revolutionary. From the radio to internet many began as private offerings and were then taken up by the state or even municipality for public service at subsidized costs. The municipal WiFi network was one such idea where in the initial stages it evoked a lot of enthusiasm. Municipal broadband is a system provided by the city-wide broadband network at very cheap price less than DSL or cable modem service. These were the unlicensed Wi-Fi, but fiber optics and WiMAX were also used for municipal broadband. From the year 2005 to 2008, more than 300 "city clouds" came to be which were abandoned halfway. These included the mesh networking to allow WiFi nodes to wirelessly interconnect the mobile ad hoc networks--MANET and the MeshNetworks of Motorola and the municipality service providers like Seattle wireless were some of the early contenders. As the movement advocating a free community WiFi grew, San Francisco experimented with a community LAN. Many protocols were designed around it including the Predictive Wireless Routing Protocol--PWRP and the enthusiasts were seen to predict in 2005 that by 2010 the municipal Wi-Fi networks would cover 126,000 square miles. This did not materialize because of the costs that were exponential. The cost of installing the

GPS-tracking, radars, lasers, cybersecurity software, and “vehicle-to-vehicle” (V2V) communication technology (2015).” Many companies are experimenting this technology in their car such as Google, General Motors

Connected-vehicle systems use wireless technologies to communicate in real time from vehicle to vehicle and from vehicle to infrastructure (e.g., radio waves or Dedicated Short-Range Communication).

With the growing popularity of wireless internet and intranet technology, Wifi-Hotspot is a common buzz word in the telecommunication engineering environment. The features and options that wireless hotspot offers it has became one of the most popular internet connectivity solution and the best choice for internet user on the move. Restaurants, cafés, Railway platforms, Airports, Hotel-motel, resort, park, wherever there are

Abstract-Li-Fi stands for light fidelity, uses LED of data transfer. This technology was proposed by by the German physicist—Harald Haas. This paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. The paper also the study on advantages as well as disadvantages of using LiFi in transferring data from one computer to another computer. The use of this technology can reduce many problems of currently used data transfer technology

The implementation of light fidelity (Li-Fi) is the next step towards a world characterized by the Internet of Things (IoT) because it will enable faster communication, release pressure off of the RF spectrum, and increase network security. Li-Fi, like WiFi,

An immediate hit on the body by an electrical discharge is deadly. People and other living creatures are unreasonably little and delicate to face this power of nature. Review that lightning unleashes heat more noteworthy than that of the surface of the Sun, with the ability to part trees down the middle.

First, this vision points towards a significantly increased (in comparison to earlier generations) set of stakeholders that 5G needs to accommodate when providing communication solutions. Examples of stakeholders are:-
