Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter. Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.

In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It typically connects to the service provider's network via the Internet through a wired broadband link ; current designs typically support four to eight simultaneously active mobile phones in a residential setting depending on version number and femtocell hardware, and eight to sixteen mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE solutions.

In January 2016, it was announced that Sony was acquiring Altair for $212 Million. Altair was renamed Sony Semiconductor Israel on March 29, 2020.
A decentralized physical infrastructure network is a type of blockchain Internet-of-Things network designed to allow devices to contribute their data in a decentralized way. DePIN aims to create decentralized systems where infrastructure, such as telecommunications, transportation, and energy grids, are governed and operated through community-driven protocols. By leveraging decentralized finance (DeFi) and smart contracts, DePIN enhances transparency, efficiency, and accessibility in infrastructure management, fostering innovation and reducing reliance on traditional centralized systems.
Weightless was a set of low-power wide-area network (LPWAN) wireless technology specifications for exchanging data between a base station and many of machines around it.
Small cells are low-powered cellular radio access nodes that have a ranges of around 10 meters to a few kilometers. They are base stations with low power consumption and cost. They can provide high data rates by being deployed densely to achieve high spatial spectrum efficiency.
A short-range device (SRD), described by ECC Recommendation 70-03, is a radio-frequency transmitter device used in telecommunication that has little capability of causing harmful interference to other radio equipment.
Golan Telecom is a telecommunication provider and mobile network operator in Israel. It was founded in 2010 and offers a range of mobile phone, telecommunications and internet services to residential and business customers. In July 2011 the company won a tender to operate a 3G wireless network in Israel beginning in 2012, The company was one of the first low-cost mobile phone companies that led to increased competition in the cellular communications market in Israel, due to the price policy adopted by the company at the beginning of its activity.
A low-power, wide-area network is a type of wireless telecommunication wide area network designed to allow long-range communication at a low bit rate between IoT devices, such as sensors operated on a battery.
Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. The specification was frozen in 3GPP Release 13, in June 2016. Other 3GPP IoT technologies include eMTC and EC-GSM-IoT.
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. The C band is used for many satellite communications transmissions, some cordless telephones, as well as some radar and weather radar systems.
LoRa is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo, a company of Grenoble, France, and patented in 2014. Cycleo was later acquired by Semtech.
5G NR is a radio access technology (RAT) developed by the 3rd Generation Partnership Project (3GPP) for the 5G mobile network. It was designed to be the global standard for the air interface of 5G networks. It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G long-term evolution (LTE) standard.
Wize technology is a low-power wide-area network technology using the 169 MHz radio frequency. It was created by the Wize Alliance in 2017. Derived from the European Standard Wireless M-Bus, it has mainly been used by utility companies for smart metering infrastructures (AMI) for gas, water and electricity but is equally open to other applications in industry and 'Smart City' spaces.
mioty is a low-power wide-area network (LPWAN) protocol. It is using telegram splitting, a standardized LPWAN technology in the license-free spectrum. This technology splits a data telegram into multiple sub packets and sends them after applying error correcting codes, in a partly predefined time and frequency pattern. This makes a transmission robust to interferences and packet collisions. It is standardised in the TS 103 357 ETSI. Its uplink operates at the 868 MHz band, license free in Europe, and 916MHz band in North America. It requires a bandwidth of 200 kHz for two channels.
Cellnex Telecom is a Spanish wireless telecommunications infrastructure and services company with up to 135,000 sites -including forecast roll-outs up to 2030- throughout Europe. Its activity is divided into four main areas: services for telecommunications infrastructures; audiovisual broadcasting networks; security and emergency network services; and solutions for the intelligent management of urban infrastructures and services.
Static Context Header Compression(SCHC) is a standard compression and fragmentation mechanism defined in the IPv6 over LPWAN working group at the IETF. It offers compression and fragmentation of IPv6/UDP/CoAP packets to allow their transmission over the Low-Power Wide-Area Networks (LPWAN).
Connected Baltics is an Estonian telecommunications company founded in 2016. It is the exclusive operator of the Sigfox network in Estonia, a low-power wide-area network (LPWAN) technology for the Internet of Things (IoT).
