Different Indoor Broadcasting Schemes Based On Plc And Vlc

“They are your kids, not mine!” The typical excuse content area teachers will say to the ESOL teachers when any issue arises regarding the education of the emerging bilingual students. The truth is that everyone in the school building, including content area teachers, office personnel, and administrators, should be involved in educating the emerging bilingual students, not only the ESOL teacher. Content area teachers need to be aware that if the students are not proficient in the new language, they will have challenges in all the content classes. Even in the Common Core Standards, the expectation is for teachers to develop not only their content area, but at the same time improve the academic language. One reason is that since the Common

This example focuses on the use of satellite networking, to broadcast the signal from the satellite, to the ground station. This type of technology involves the use of Zigbee at small distances, and WiMax for greater distances.

Verizon’s T-1 link will be used for the network connection throughout the building. Cisco 4500 series switches will be used in the setup of 240 ports which will be more than enough for the 10/100/1000 baseT Ethernet communication, each switch will have a location in the a server room on each floor. Virtual Lans in the switches will give a OSI layer 2/3 container for every one of the network subnets in the table shown above; this will make sure that each host will have a small amount of interference with other hosts on the network. Active Directory is what will be used in the network, this will be used to authenticate and authorize users through a single sign on service which will secure UMUC’s vulnerable data. UMUC’s network will need a Dynamic Host Configuration Protocol which will be a simply way manage the IP addresses across its network. Microsoft DHCP will also be used because of the vulnerability of a fake DHCP server being able to cause network problems with a authorized Dynamic Host Configuration Protocol. DHCP will broadcast to for a discovery signal, and the relay service will then start up all of the Cisco 4500 series switches so that the DHCP discovery packets to go out to Virtual LAN areas. Layer 2 core network service is going to be broadcasted by the Cisco series 4500 switch which will be in the first floor’s IT closet; doing this will stop the routing decision delays throughout the network

 Data and voice access points. Bluetooth facilitates real-time voice and data transmissions by providing

In practice, there are some devices on market do not reach devices may reach up to several meter. The normal spot for IrDA communications is from 5cm to 60cm away from transceiver

The Bluetooth specification has 2 power levels; a lower power that covers the shorter personal area within a room, and a higher power level that can cover a medium range, such as within a home. The distance covered by Bluetooth is commonly 30ft, but it can also cover larger area up to 100 ft.

For this project, we have the possibility or choice to use either Bluetooth or Wi-Fi Direct to facilitate the communication between the system and the app.

Products using the lower 3.4-4.8 GHz spectrum will be required to implement detection and avoidance (DAA) technologies to avoid interference with other services are operating at the same frequencies. When the spectrum conflict is detected, the UWB signal strength has to be dropped. Data rate limitation is also a concern. Currently, the multiband OFDM (MB-OFDM) UWB systems can provide maximum data rate of 480 MB/s. This data rate can only support compressed video. Data rate for uncompressed video for high definition TV, such as high-definition multimedia interface (HDMI), can easily go over 2 GB/s. Although the MB-OFDM UWB can be enhanced to support 2 GB/s, the complexity, power consumption, and cost

Traditional TV programs are broadcasted through a rooftop antenna, satellite dish, phone line, coaxial cable or fiber-optic cable. With traditional linear programming someone else has decided what you can watch on TV and when you can watch it, since certain programs come at certain times. As, channel lineups have grown over the years, referring to Appendix A. Of all the channels in the lineup, selection is still limited because of time slot programming and

The application of LED in the fields of communication becomes the recent research topics with its low cost advantage, high confidential and wirelessly environment. The Japan-based Visible Light Communication Consortium was being introduced in 2002. In the United States, the Centre of Ubiquitous Communication by Light carry out research to enable wireless communication by implanting signals into the light emitted by next generation LED in systems for different purposes such as traffic control, advertising and illumination. In Europe, the OMEGA Project was started with its aim to enhance a home area network capable of delivering high-bandwidth services and operate at a transmission speed of 1 GB/s.[6] A real time white light phosphor LED visible light communication with compact size was being introduced whereby a few techniques was being proposed to increase the data rate of phosphor LED such as high spectral-efficiency modulation, digital equalization method, optical multi-input multi-output(MIMO) and optical blue filtering.[7]

In designing base stations, it is very important to have the knowledge about the electromagnetic environment where the system is operated, and the location of the transmitter and receiver. it is difficult to predict indoor radio propagation because of the dense multipath

Hardware will be develop after the wiring diagram have been verified. Hardware will connect with National Instrument (NI-DAQ) and PC. This is to run the whole program of the

means of analog lters. Due to this reason only, a number of studies in the

In current scenario, various sensors of plant is connected to the PLC for the data communication and PLC is program such that it give controlling output according to the threshold value of sensors. In this if the value of sensor is below or above the sensor value then it gives the respective output. This output is nothing but the controlling output from the PLC which gives signal to controlling device like value or alarm etc. Also SCADA provide the Graphical user interface to the PLC unit so that any programmer can see the process graphically with the help of SCADA. In Plant SCADA and PLC are connected to each other which make a whole system for Data communication and its controlling. There are various types of PLC are available in the market. The selection of the PLC can be done as per the requirement of number of input and output associated with the plant.

Many research has revealed the theoretical throughput of Li-Fi system can be much greater than a traditional wireless radio communication systems as higher frequency will transmit a higher data rate. e.g. the visible light bandwidth spectrum is 10,000 times more than RF frequency band. With various experiment, the Li-Fi bit rate has been greater than 1Gbps. At home or office Li-Fi with the bit rate of 224 Gbps which is 100 times faster than the average WI-FI connection. With a larger modulation bandwidth, Khalid et al. presented a link implementation that can achieve a 3.4 Gbps link with an off-the-shelf RGB LED. Tsonev et al. have showed a data rate of 3.5 Gbps from a single-color micro LED in a single-input– single-output (SISO) setting. (Dimitrov, S. & Haas, H. 2015)
