NB-IoT
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 ( LTE Advanced Pro), in June 2016. Other 3GPP IoT technologies include eMTC (enhanced Machine-Type Communication) and EC-GSM-IoT. NB-IoT focuses specifically on indoor coverage, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications. IoT applications which require more frequent communications will be better served by LTE-M, which has no duty cycle limitations operating on the licensed spectrum. In March 2019, the Global Mobile Suppliers Association (GSA) announced that over 100 operators had either NB-IoT or LTE-M networks. This number had risen to 142 deployed/launched networks ...

LTE-M
LTE-M or LTE-MTC ("Long-Term Evolution Machine Type Communication") is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications. LTE-M includes eMTC ("enhanced Machine Type Communication"), also known as LTE Cat-M1, whose specification was frozen in June 2016 as part of 3GPP Release 13 ( LTE Advanced Pro), as well as LTE Cat-M2. Competing 3GPP IoT technologies include NB-IoT and EC-GSM-IoT. The advantage of LTE-M over NB-IoT is its comparatively higher data rate, mobility, and voice over the network, but it requires more bandwidth, is more costly, and cannot be put into guard band portion of the frequency band for now. Compared to LTE Release 12 Cat-0 modem, an LTE-M model is claimed to be 80% less expensive (in terms of the bill of materials), support up to 18 dB better coverage, and a battery lifetime that can last up to several years. In March 2019, the Global Mobile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LoRaWAN
LoRa (from "long range", sometimes abbreviated as "LR") 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. In March 2012, Cycleo was acquired by the US company Semtech. LoRaWAN (long range wide area network) defines the communication protocol and system architecture. LoRaWAN is an official standard of the International Telecommunication Union (ITU), ITU-T Y.4480. The continued development of the LoRaWAN protocol is managed by the open, non-profit LoRa Alliance, of which Semtech is a founding member. Together, LoRa and LoRaWAN define a low-power, wide-area (LPWA) networking protocol designed to wirelessly connect battery operated devices to the Internet in regional, national or global networks, and targets key Internet of things (IoT) requirements, such as bi-directional communication, e ...

Internet Of Things
Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The IoT encompasses Electronic engineering, electronics, Telecommunications engineering, communication, and computer science engineering. "Internet of things" has been considered a misnomer because devices do not need to be connected to the public internet; they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, and increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022. .

Low-power Wide-area Network
A low-power, wide-area network (LPWAN or LPWA 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. Low power, low bit rate, and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and carry more data, using more power. The LPWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel. A LPWAN may be used to create a private wireless sensor network, but may also be a service or infrastructure offered by a third party, allowing the owners of sensors to deploy them in the field without investing in gateway technology. Attributes # Range: The operating range of LPWAN technology varies from a few kilometers in urban areas to over 10 km in rural settings. It can also enable effective data communication in previously infeasible indoor and underground locations. # Power: LPW ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weightless (wireless Communications)
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. History Cambridge Wireless held an event at the Moller Centre in Cambridge, United Kingdom on September 30, 2011. Neul, Landis+Gyr, Cable & Wireless, and ARM Holdings provided presentations. The Weightless Special Interest Group promoted the technology (SIG), announced on December 7, 2012. The group was led by William Webb, a professor at Cambridge and a founder of the company Neul. A subsequent event was held in September 2013, when version 1.0 was published. The name Weightless was chosen to reflect the intention at a low overhead per transmission for devices that need to communicate just a low amounts of data. The Weightless logo appears in uppercase letters with the 'W' appearing in the top-right corner of a light blue box with a solid blue line above it. In September 2014, Neul was acquired by Huawei fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Static Context Header Compression
Static Context Header Compression (SCHC) is a standard compression and fragmentation mechanism defined in thIPv6 over LPWAN working groupat the IETF. It offers compression and fragmentation of IPv6/ UDP/ CoAP packets to allow their transmission over the Low-Power Wide-Area Networks (LPWAN). Compression scheme tailored to LPWAN About LPWAN Low-Power Wide-Area Network (LPWAN) gathers the connectivity technologies tailored for Internet of Things (IoT), allowing for: * long-range communication (up to 40 km), * very low energy consumption (on the device side), * and energy efficiency (for networks). The trade-off for achieving these features includes severe limitation in terms of throughput and packet size supported. Also, LPWAN come with limitations on transmission modalities since, in order to save battery, devices are dormant most of the time and wake up only episodically to transmit and receive data for a short time window. As a result, the LPWAN use their specific pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G UMTS/ HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; but the original version did not meet the technical criteria of a 4G wire ...
