Wireless

Every day millions of people rely on cell phones and other wireless devices for communication. Base stations, distributed antenna systems (DAS), small cell networks, and Wireless Local Area Networks (WLAN) play a key role in facilitating uninterrupted services. These technologies serve several crucial functions to ensure successful communication and are critical in ensuring the uninterrupted flow of data to and from a wireless device.

Base stations transmit wireless signals to hand held devices using signal amplifiers, and also receive transmissions back from those same devices through sensitive receivers. These towers make use of a complicated series of narrow pass band filters, power amplifiers, low noise amplifiers, splitters, combiners and signal attenuators. A DAS network is comprised of many antennas that are used to improve wireless coverage within heavily trafficked areas, such as stadiums, corporate offices and public. Similar to DAS systems, small cell networks utilize low-powered radio access nodes that increase the network capacity for in-building and outdoor wireless service. These wireless infrastructures continue accommodate the increased market demands of increased bandwidth, speed and capabilities.

Applications:

  • Long Term Evolution (LTE), more commonly marketed as 4G LTE, is an industry standard for wireless communication of high-speed data for mobile phones and data terminals.
  • WiFi is a local area wireless network that allows an electronic device to connect to the internet using 2.4 GHz UHF and 5 GHz SHF radio waves.
  • Code-Division Multiple Access (CDMA), a digital cellular technology that uses spread-spectrum techniques. This
  • Time Division Multiple Access (TDMA), a technology for delivering digital wireless service using time-division multiplexing.
  • Global System for Mobile Communications (GSM), one of the leading digital cellular systems. GSM uses narrowband TDMA, which allows eight simultaneous calls on the same radio frequency.
  • General Packet Radio Service (GPRS), a standard for wireless communications which runs at speeds up to 115 kilobits per second.
