Wireless sensor network
LPWAN is low-power wide-area network also known as LPWA Network — is a new type of radio technology used for wireless data communication in different Internet of Thing applications and M2M solutions. Key features inherent in the technology are the long range of communication, low bit rate and small power budget of transmission.
Right place for LPWAN
There are several wireless technologies allowing today to deploy wireless sensor network. They are suitable for different applications with regards to bandwidth and range. Most of IoT and M2M solutions require long-range communication link with low bandwidth and are not well covered with traditional technologies. That is right time and place for LPWAN technology which is quite good for these emerging sensor applications.
LPWAN is the best for IoT and M2M
The unique set of LPWAN characteristics in comparison with other wireless technologies in the best way possible suited for IoT and M2M needs. The scheme below shows the benefits of low-power network relative to traditional ones.
General LPWAN characteristics
- Range from 5 to 30 km in different environment conditions.
- High autonomy of smart devices with a lifetime from 10 to 20 years.
- A small portion of data transmitted with low throughput which is may vary from few bit/sec to 100s bit/sec.
- Inexpensive radiomodules and chipsets depending on vendor may vary from few dollars to 10s dollars.
- Low latency, which is basically not a key parameter in IoT apps.
- Less number of access points (base stations, gateways) to cover wide area such as city or even country.
- Good penetration in case of sub-GHz ISM frequency used and better network coverage in the open district area.
LPWAN is the engine of long-range Internet of Things
Business needs LPWAN
Today a lot of business sectors are facing a number of communication challenges. Some applications are using Internet of Thing with cellular modems just because it provides a positive ROI even when users are paying few dollars per month per sensor for the connectivity. But there are many applications with lower ROI requirements and it is still being unconnected because of traditional communication technologies do not provide a positive return on investments with current monthly fees.
Addressing the abovementioned problem LPWA networks offer an effective solution. With this technology, the initial cost of a radio module and amount of monthly service fee is much lower (cents/month as opposed to dollars/month). Whereas a cellular modem would cost over $30, and a WAVIoT IoT module can be built for a fraction of that.
The potential of LPWAN is huge. As per analytics reports more than 20 billions of IoT devices will available by 2020 and a large portion will be connected with LPWAN. There are several LPWAN technologies present on the market now. They differ from one another by frequency, bandwidth, RF modulation approach and spectrum utilization algorithms. And as a result, they have their key points to consider when choosing a right technology for Internet of Things.
LPWAN-powered applications for IoT
There are a lot of enterprises, industrial and municipal business sectors where LPWAN is best suited to. Here some examples of IoT applications where LPWAN is perfect technology delivering a long-range and cost-effective connectivity. LPWAN is perfect to connect a high volume of low data-intensive sensors cost-effectively, rapidly and at a large area of a city or even country.
Utility companies collect water meter readings very sporadically without a reliable system for online monitoring. GPRS, other wire or wireless technologies are limited and unprofitable. LPWA network covers a hundred of square miles and delivers small data to an automated metering system in real time with no need of physical visits.

Smart Grid Control
Nowadays most of the electrical companies supply an electricity to customers with no feedback and real-time consumption monitoring. Making electricity grids smarter allows getting more efficient energy transmission, economy for suppliers and consumers, as well as effective load balancing.

Smoke Detectors / Fire Alarms
Smoke detectors, fire alarms, and other related security systems are important for safety. Therewith they do not need to send a lot of data to the monitoring person. Actually, there is a need to transmit signal with current sensor working status and alarm messages. LPWA network is perfectly suited to such application requirements.
