The growth of the Internet of things will affect enterprises and the networks they access. The business aspect of the Internet of things is crucial to the cost, revenue and profit of enterprises. Economically connecting billions of IOT devices is a challenge. The introduction of low power wide area (lpwa) cellular technology is a solution.

Service Internet of things equipment

The network architecture of wireless Internet of things equipment shall:

Support remote communication

Low power consumption and long battery life operation

Manage a large number of endpoints

Support for low latency and high latency (latency) applications

Handling radio interference

Provide secure communication

Operate through one-way and two-way communication

Allows a range of applications, many of which have not yet been discovered

Introduction of low-power wide area technology

Low power wide area (lpwa) technology is a solution. They need to coexist with cellular mobile networks and other short-range technologies. This coexistence will vary according to the local cellular market. Lpwa network is a competitive advantage. Differences between technology types include the radio spectrum used (licensed and licensed spectrum) and the local market strategy of the network provider.

Lora Alliance

The mission of the Lora alliance is to develop a global standard for lpwa to support and stimulate the Internet of things, machine to machine (M2M), industrial and consumer applications. Alliance members work together to promote the global adoption of lorawan. This is achieved by sharing knowledge and experience to ensure interoperability between operators and IOT endpoints.

Lo RA alliance is a low-power wide area network (lpwan) specification for wireless battery operated IOT devices. Lorawan aims at IOT devices, such as secure two-way communication, mobility and location services. It provides the Internet of things without complex interoperability standards between local devices.

Lorawan network architecture is usually configured as a star (cluster) topology, in which the gateway supports a transparent bridge for message relay between IOT devices and network servers. The gateway connects to the network server through an IP connection. IOT devices use single hop wireless communication to one or more gateways. Internet of things device communication is expected to achieve two-way. Multicast operation supports operation software upgrade or other quality allocation transmission to reduce communication time, thus saving cellular network time.

What will the enterprise encounter?

There will be a large number of IOT devices that need to be paid, maintained and monitored. The data center will need new applications. The number of addresses of Internet of things devices will grow explosively. Alternatively, cloud services can be used to reduce the burden and capital expenditure of IT personnel. If the cloud provider is allied with a specific IOT device supplier, the lpwa solution may be proprietary, resulting in supplier and cloud lock-in. Most IOT messages are short and may be sent regularly unless some events trigger streaming.

Cellular network providers may add lpwa technology to support these devices and price very low access costs. One obstacle is the lpwa connection that needs to be supported in the building. Many community services cannot penetrate the interior of the building, especially the basement. We may see lpwa signal booster on the market to solve this problem.

Finally, enterprises will face the challenge of determining the ROI of IOT device deployment. The payback period is likely to be as long as several years. The reason may be related to retaining customers who may be robbed by competitors.
