M2M and IoT or Internet of Things will give rise to billions of nodes that require connecting. Most of these will require only low bandwidth to transfer small amounts of data. Some will also require this to be connected over distances greater than those achievable simply by a transmitter on its own. For many of these applications, the traditional cellular phone systems are too complex to allow for very low power operation, and too costly to be feasible for many small low cost nodes.
Focusing on measure of success in communication, the latest present scenario “IoT Network” plays a vital role in the development of communication between the various modes. in which ,the major controlling of all the operations in any remote smart devices depends upon the network modules.
The modules for the communication is preferred based upon the convenient of the smart devices developed. Mainly depends upon the range,
- Power Consumption
- Efficiency
- Losses
- Dimension-ally distance
LPWAN NETWORK
Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a type of wireless telecommunication network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery.
LORA
LoRa Technology offers a very compelling mix of long range, low power consumption and secure data transmission. Public and private networks using this technology can provide coverage that is greater in range compared to that of existing cellular networks. It is easy to plug into the existing infrastructure and offers a solution to serve battery-operated IoT applications. Semtech builds LoRa Technology into its chipsets. These chipsets are then built into the products offered by our vast network of IoT partners and integrated into LPWANs from mobile network operators worldwide.
SIGFOX
SIGFOX is a cellular style system that enables remote devices to connect using ultra-narrow band, UNB technology.
For a host of applications from smart meters to control nodes that need connectivity over long ranges the only option until recently has been to use a cellular connection. This option has several disadvantages because cellular phone systems are focussed on voice and high data rates. They are not suited to low data rate connections as the radio interface is complex and this adds cost and power consumption - too much for most M2M / IoT applications.
The SIGFOX network is aimed at providing connectivity for a variety of applications and users. It is not aimed at one area, but at being for general use by a variety of different types of users. The SIGFOX network performance is characterised by the following:
- Up to 140 messages per object per day
- Payload size for each message is 12 bytes
- Wireless throughput up to 100 bits per second
WEIGHTLESS-P
Weightless is both the name of a group, the Weightless Special Interest Group (SIG), and the technology. Weightless technology delivers wireless connectivity for low power, wide area networks (LPWAN) specifically designed for the Internet of Things. Weightless can operate in both sub-1GHz licence exempt and licensed spectrum.
The Weightless SIG is a non-profit global standards organisation formed to coordinate the activities needed to deliver the world's best IoT connectivity technology. These activities include:
- Developing the definitive open standard LPWAN technology for IoT connectivity
- Managing ongoing evolution, innovation and upgrades to the Standard
- Administering the IPR policy
- Managing legal disputes
- Communicating and evangelising the technology
- Managing test, certification and licensing of the technology
Application for these Modules
- Home and consumer goods
- Energy related communications - in particular smart metering
- Healthcare - in particular the mHealth applications that are starting to be developed
- Transportation - this can include the automotive management
- Remote monitoring and control
- Retail including point of sale, shelf updating, etc
- Security
