The way out of Lora

Lora and Sigfox such as the ISM band network in the end can survive. How to compete with NB-IoT.
Lora and Sigfox, NB-IoT are Lpwan networks, Sigfox use the ISM band, their own, many are private, and operators to establish a nationwide network to do their own operators, such as China Unicom and mobile;
Lora also use the ISM band, this is the practice of old Mao crowds, many manufacturers involved in, now the momentum over sigfox one end;
NB-IoT is the latest, and the most current, Lpwan technology, as the major carriers can support it through a simple upgrade.

As far as technology is concerned, Lora should be the best, capable of supporting uplink and downlink data transmission; NB-IoT only supports upstream!!
But as far as the market is concerned, Lora is using ISM, which is a non-fee frequency band, no charge is to double-edged sword, free band to make its low cost, but free management, we casually use, but for long-distance network, it is easy to cause interference, which manufacturers dare to use such things. Which commercial customers dare to use such things ...

At present, only private network users can use this network, or in remote mountains and forests!!
Currently, it is not possible to evaluate forest fire protection because the sensors used for fire monitoring are too power-hungry, and if you can deploy a large number of sensors, you need a low-powered WAN. And the development of forest fire prevention video surveillance is more mature.
But how the sensor's electricity is solved is an important problem in remote mountainous areas and forests!!! How to resolve. Solar...

Lora Actility do the largest, but only deploy a number of base stations, no large-scale node access;
Sigfox Circle A lot of money, and many operators to deploy the base station, as if there are not many nodes access;
NB-IoT terminal chip does not come out, the end of the year will come out, we expect a relatively high, but exactly how, the specific will face what problems, after 1-2 years of testing to know ...

Busy two years on the Lora, originally conceived very good, low power, long-distance network should have a lot of application scenarios, but the brutal reality education me, too optimistic ...
