Why does the high-precision positioning scheme like to use LoRa to return

2024-07-04

In our research process of "2024 China's high-precision positioning technology industry white paper", we saw a common phenomenon: in the high-precision positioning scheme, most of them will choose to use LoRa for data transmission.

Regarding LoRa technology, we are also very familiar with it. It is regarded as the originator of domestic LPWAN technology. However, after many years, the development of LoRa industry is far from meeting industry expectations. Even in the domestic market, it is facing the dilemma of many domestic technology solutions to further compress the living space.

However, in the high-precision positioning scheme, LoRa is rooted as a backhaul technology.

In this article, I will briefly analyze why LoRa can take root in this industry.

First of all, we analyze the current market technology options for positioning solutions represented by UWB.

Scenarios where positioning technology solutions such as UWB need to be returned are mainly used in the IoT industry market (B-end market).

In this market, UWB or Bluetooth AoA or GNSS are all positioning information sources. In addition to this positioning network, there is also a networking cost in the complete scheme, because UWB data generally need a separate communication transmission technology to transmit them to the background for settlement and system application.

As can be seen from the above topology diagram, both uplink positioning mode and downlink positioning mode need networking, but the cost of networking is different.

From the analysis of the above table, there are their own applicable conditions and inapplicable conditions for which technology to choose for connection networking. In terms of cost, the cost difference of each connection networking technology is not very large under their respective applicable scenarios. Of course, LoRa is because its applicable scenario is that the public network cannot be covered and needs to be supplemented with additional networks, thus increasing the cost of the base station.

Through the analysis of the above table, whether it is a base station network or a label network, a single device network with the same connection technology, there is no difference in cost.

Therefore, to sum up, the positioning scheme likes to use LoRa to return mainly based on the following considerations:

First, many projects in the B- end industry are relatively cheap or seriously shielded. The public network coverage of operators is not so good, and it is too expensive to add base stations alone. Therefore, in the B- end industry, users often need to set up a separate network in order to ensure full coverage.

Second, in the B- side industry, many users have private network requirements and do not want data to be uploaded to the public network. After all, a lot of information in the B- side industry is closed, especially the data of positioning personnel, which is generated under closed management. And group private network also has a variety of technologies, why choose LoRa? That is the next factor.

Third, in the private network scheme, the overall cost performance of LoRa is relatively high. On the one hand, LoRa has a relatively high industrial maturity. Compared with other niche private network technologies, LoRa has more players and is easier to find solution providers in the market. In addition, the price of the product is not expensive. In addition, LoRa has a long transmission distance, and basically a project can be covered by only a small number of base stations, this will also reduce costs.
