Distributed Antenna System – An Update

Flexible, secure, and comfortable Wireless apps. Wires can go bad or get tangled and can make an application difficult to trouble shoot if there is a communication problem. As systems increase in size, often wired applications increase in the amount of wires which can be problematic. If you want to connect with a tank in a remote area, want to check the status of something from a remote location, or don’t want to add any cables, wireless solutions will aid. You can use wireless equipment for long range connectivity with remote tank networks, or you can use the cellular network. Infrared systems can be used in indoor devices, instead of cables.Click Advanced Telecom Systems

Here’s a short list of 3 wireless technology types: Zigbee Wireless Technology runs at a frequency of 2,4 GHz. This embraces topologies of circle, circles, and tree clusters. It’s a simple, general purpose, self-organizing and robust thing to do. Zigbee networks allow that one host or master such as ZB-2550-T be the network controller to setup and decide the most efficient communication route between nodes. ZB-2550-T will carry wireless communication to Zigbee viaRS-485 orRS-232. Zigbee networks may have many slave routers, such as ZB-2551-T, for end user transmitting and receiving. ZB-2551-T will carry wireless communication to Zigbee viaRS-485 orRS-232. With Zigbee equipment such as ZB-2550-T and ZB-2551-T the usual contact wavelength is 100 meters and the main antenna is omni-directional. Longer range models can provide up to 700 meters of contact. Directional antennas such as ANT-15YG or omnidirectional antennas such as ANT-15 may stretch transmission of information up to 9 Km. Per Zigbee network has an RF path, a PAN ID and a specific node ID. Network setup is achieved through a program application. Zigbee networks endorse modes of communication which are visible, transmitted or Modbus.

Infrared technology takes advantage of electromagnetic radiation. IR-210 is a universal remote learning application, which can acquire and save up to 176 IR commands to a register. This runs at frequency 32 to 56 KHz. IR-210 has an RS-232 port and an RS-485 port, so that Modbus RTU-based master devices can connect with IR slave devices such as televisions, projectors and lighting controls. IR-210 has a device feature that helps you to customize Baud Rate, Net ID, User Title and Commands. The standard gap of contact between the IR-210 and end devices such as digital image frames is up to 7 metres.

Radio Frequency Technology can operate at a frequency of 900 Mhz. This follows topologies of point to point or multipoint. For eg, SST-900 has 16 customizable RF channels, and different AP modes such as Slave / P2P and Slave / Broadcast. Radio Frequency Engineering facilitates modes of communication peer-to-peer or transmitted. The RF network of SST-900 can be programmed with a software tool that allows you to customize an RF path, community ID, AP mode, data type and baud rate. The SST-900 has an internal self-tuner and has a standard 1000 meter wireless communication capability.
