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 to accommodate the increased market demands of increased bandwidth, speed and capabilities.

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.
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.
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.
Base Station Antennas
Macro base stations have evolved to be more efficient with Massive MIMO antennas. Many antenna elements and other components in a compact housing, coupled with technologies like beamforming, vastly improve coverage and capacity per antenna.
MIMO or “Multiple-Input Multiple-Output” refers to antenna technology that expands radio capacity by sending and receiving multiple data signals simultaneously over the same channel.
Short-range radio nodes that supplement macro base stations and create local wireless networks. Dense installations of small cells will be elemental to 5G, providing significantly increased network capacity and support of high data rates.
Backhaul units connect local or “edge” networks to a core network. Wireless units are instrumental in servicing low-coverage areas where fiber optic cabling is prohibitive. Backhaul can also help handle rising mobile data rates.
Distributed Antenna Systems
Distributed antenna systems (DAS) are networks ir antenna nodes that increase wireless coverage in areas of high user volumes or low line-of-sight to infrastructure. Stadiums and underground transportation are common DAS applications.
Fixed Wireless Broadband
Access points mounted outside of buildings and residences enable wireless internet access for end users. These units connect to wireless infrastructure. Eliminating hard wired access to Internet services at consumer premises.
End users gain access to mobile networks and the Internet through wireless devices. User mobile devices include smartphones, tablets, laptops and hotspots. 5G technology will expand mobile applications to 4K video streaming, virtual reality and more.
IoT or the “Internet of Things” refers to the connection of objects to the Internet. 5G will enable IoT at massive scales, driving data transfer and analytics in applications from smart cities to industrial automation.
Mission-critical communication requires high bandwidth, low latency data transfer. Historically, only wired protocols have achieved these features. 5G technology is predicted to enable wireless critical communications for industrial automation and more.
Embedded wireless modules enable devices to send and receive data. Modules house components in a standard package making it easier for manufacturers to integrate wireless connectivity into devices from smart appliances to industrial controls.
