GLOSSARY

2G - first introduced in 1992, is the second-generation of cellular telephone technology and the first to use digital encryption of conversations. 2G networks were the first to offer data services and SMS text messaging.

3G – successor of 2G offering faster data transfer rates and are the first to enable video calls. This made it especially suitable for use in modern smartphones, which require constant high-speed internet connection for many of their applications.

4G - The fourth generation of mobile phone communications standards. It is a successor of the 3G and provides ultra-broadband internet access for mobile devices. The high data transfer rates make 4G networks suitable for use in USB wireless modems for laptops and even home internet access.

5G - The generation of mobile phone communications standards currently under development. 5G should be rolled out by 2020 to meet business and consumer demands. In addition to faster speeds, 5G networks will also meet the needs of new use-cases such as the Internet of Things as well as broadcast-like services and lifeline communications in times of disaster.

AHJ - Where public safety is primary, the AHJ may be a federal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority.

BDA - When strategically placed in a building, a bidirectional amplifier (BDA) receives the signal from an antenna which is located in an area unobstructed from the cell tower, such as on the roof of a building. After the BDA receives the signal, it then distributes the signal to places that would otherwise be unreachable. The BDA can increase, or amplify, the strength of a signal as it passes through, allowing the signal to stay strong even as it continues to travel further from the signal source.

Category Cable - Category (CAT) cable is a multi-pair (usually 4 pair) high performance cable that consists of twisted pair conductors, used mainly for data transmission. Basic CAT cable was designed for characteristics of up to 100 MHz CAT cable is typically used for Ethernet networks running at 10Mbps to 1Gbps.

CBRS - CBRS (Citizens Broadband Radio System) uses TD-LTE to provide a wireless voice and data service at 3.5GHz (3550MHz to 3700MHz). The radio interface is exactly the same as for LTE at other frequencies, supporting voice, text and data services with seamless mobility. This frequency allocation spans existing LTE Band 42 (3400MHz to 3600MHz) and LTE Band 43 (3600 to 3800 MHz).

DAS - DAS stands for Distributed Antenna System, which is a system that allows for the use of cell phones and other wireless devices in areas that do not have direct access to a cell tower or power source. DAS works by receiving power from a radio frequency (RF) source, and distributing it over a system of cables and antennas so that the signal reaches throughout a building or space.

Donor Signal - RF signals from a cell tower or signal source.

IoT - The Internet of things (IoT) is the extension of Internet connectivity into physical devices and everyday objects. Embedded with electronics, Internet connectivity, and other forms of hardware (such as sensors), these devices can communicate and interact with others over the Internet, and they can be remotely monitored and controlled.

Millimeter Wave - The term “millimeter wave” derives from the wavelength of radio signals on frequencies between 30 GHz and 300 GHz, which ranges between 1 and 10 millimeters.

PoE - Power over Ethernet (PoE) describes any of several standard systems which pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices such as wireless access points, IP cameras, and VoIP phones.

Private LTE - A Private LTE network leverages micro towers and small cells—similar to a Wi-Fi access point—on-site to replicate the larger public network. Private LTE can be based on licensed, unlicensed, or shared spectrum. Immediate applications would be in Manufacturing, Storage, Remote campuses, and Maritime.

RSRP - Reference Signals Received Power is a measurement of the received power level in an LTE cell network.

RSSI - RSSI is an indication of the power level being received by the receive radio after the antenna and possible cable loss. Therefore, the higher the RSSI number, the stronger the signal

Wi-Fi Calling - A voice call via a Wi-Fi network. Call quality is subject to the quality of the W-Fi network and not the WSP.

WSP - Wireless Service Provider (WSP) is a telecommunications service provider organization that provides wireless voice and data communication for its subscribed mobile users.
