IoT’s Top Wireless Standards

IoT

IoT has been experiencing accelerated growth in the recent past. More homes, offices, and industries are embracing this idea that is promising to change how we do live our lives. If the growth rate is maintained, it expected that by the year 2020, manufacturing, logistics and transportation and utility companies are expected to spend $40B each on IoT. During this same period, IoT market is expected to rise to $541B for ICT spend alone.  To match this growth, new wireless standards have bee cropping up. Today we are going to features some of the leading wireless standards the market has to offer.

Top wireless standards

Zigbee

Zigbee is a product of Zigbee Alliance. The alliance maintains and publishes the Zigbee standard. It pushes application profiles that enable the creation of interoperable products using the Zigbee standard. Although it was conceived in 1998, hundreds of millions of devices are already using this technology. It was standardized in 2003 and revised in 2006 and has since become a very popular standard for IoT.
Zigbee is low power, low data rate, and close proximity ad hoc network. It also supports mesh networking topology. It is ideal for home and office applications since devices are usually located within a small area. It works within an area of between 10 to 100 meters, line-of-sight. It offers a data rate of 250kbps, 40 kbps, and 20 kbps.

Lora

LoRa is also an open global standard that is controlled by the LoRa Alliance which is a non-profit making organization. Unlike ZigBee, LoRa focuses on wide area networks. It is suited for long-range communications. It uses frequency bands like 169 MHz, 868MHz, 915 MHz and 433MHz which all unlicensed sub-gigahertz radio frequencies.
LoRa is ideal in situations requiring the deployment of a large number of non-critical sensors and control devices over a wide area. Since it uses unlicensed radio networks, it is ideal for city-wide environmental sensors, streetlamps control, agricultural farms, and small object monitoring. LoRa uses 64-bit and 128-bit keys for network, application and device encryption.

LTE-M

Long Term Evolution for Machines (LTE-M) is popularly known as the 4G network. It is arguably the industry’s answer to IoT’s M2M. It is a secured network that is suitable for long-range communications. LTE is a cellular carrier wireless system which is backed by GSMA and 3GPP standards organization.
LTE offers both indoor and outdoor coverage. It supports a huge number of low throughput devices, low power devices, low delay sensitivity, low device cost, and optimized network architecture. Owing to the fact that it works over cellular networks, LTE-M can be used to communicate with devices from IoT devices loaded into mobile assets like trucks, trains, boats among others.
LTE uses cell-tower positioning to provide location services hence does not need to use the satellite-based system, for instance, the GPS or Galileo. LTE is also very secure. Cellular networks use sim cards which are secured using NSA suite BAES-256 encryption and Identity Certification.

Picking the best option for your application.

When picking the best option for your application you need to consider the specific features that are critical to its functionality. You have to consider the associated cost, coverage, security, and compatibility. That way you will be able to pick the best standard for your application.

Little Know more about Brush-less Motors

Image
Brushless motors Brushless differs from conventional dc motors in the sense that it does not have brushes. Commutation is done using electronic drives to feed power to the stator windings. They consist of a rotor which is in the form of a permanent magnet and a stator that is in the form of polyphase armature windings. A  brushless DC motor  can be constructed in two ways; one is by placing the rotor outside the core and the other is by placing the rotor inside the core. How a brushless motor works Brushless motors are driven by electronic drives that  switch  the supply voltage between the stator windings while the rotor turns. There is a transducer that monitors the position of the rotor as it turns and conveys the information to an electronic controller. The controller then decides which stator winding to be energized based on the position of the rotor. Electronic drives are made up of two transistors each phase which is run by a microprocessor. T...

LED Modules: Manufacturer,Types and Application

Image
LED Modules Light-emitting diodes (LED) modules are LED self-contained devices that are designed to either function on its own or to plug into a compatible unit. These modules are mostly used in the development of both energy-efficient and portable lighting.  An LED contains several LED bulbs that are connected to a fixture that contains a battery or an alternative power supply which powers all the bulbs contained therein. LED modules can either emit white light or emit different colours based on the material they are made of. They are prominently used for advertising and signages but could as well be used for other purposes due to their versatility. Types of LED modules There are a variety of LED modules available in the market. There no specific parameters that can be used to categorize LED modules . They can be categorized in terms of efficiency, form, CCT, colour among others. Some of the common ones used in signage and advertising include; Side LED mod...

Block-chain: A Complete Beginners Guide | Block Chain Technology

Image
Blockchain technology Blockchain technology is barely three decades old, but it has completely changed global money transfer as we know it. It was first conceived in 1991 by a group of researchers who originally intended it to be used to timestamp digital documents to make it impossible to tamper with them. This concept was first put into actual use in 2009 by Satoshi Takamoto to create Bitcoin. Bitcoin has since spurred the adoption of  blockchain technology  for cryptocurrency, medical records, and land records among others.  What is blockchain? A blockchain is a network of computers that share a digital ledger that is duplicated and distributed across all participants in the network (nodes). That is to say that each node on the network has a duplicate copy of the ledger. The digital ledger keeps a chain of transactions since the creation of the network. The chain of transactions keeps growing as new blocks of transactions are approved and then added along....
