When will the IoT communication agreement war end?

Tanuj Mohan, chief executive of Enlighted, a US startup that provides building automation control solutions, said there was no obvious end to the war on the Internet of Things (IoT) protocol; the company developed its own 802.15.4-based standard. The communication agreement considers Zigbee to be bleak.

Mohan pointed out that the Internet of Things requires a series of open application interfaces (APIs) and communication protocols that work with different physical layer networks. In this model, he believes that the role of the Internet of Things should be more like an IT network. Mohan, a specialist in network technology, is a co-founder of Enlighted. He has worked for Netcom equipment vendors such as Cisco, Novell, and Novell, and has developed multi-protocol protocol routers in Hughes.

"Anyone who tries to build a physical layer that works on top of the application layer and pushes a software stack based on it doesn't work." Mohan said that the IP and network layers should not intersect with the media. "Last A glimpse of the protocol has some features, but the importance is not as high as people think; the communication protocol used by the network node is irrelevant, because any situation will require an intermediary device.

Mohan further pointed out: "Zigbee is the most cost-effective solution today, but Wi-Fi will provide a clearer answer in the future. Every few years, a new network management protocol will emerge, such as SNMP. Or CORBA, the Internet of Things field will continue to evolve so that people will need an open API."

Mohan also believes that the Zigbee standard at 250 kbit/s is too slow and too complicated for building control applications: "You don't want the network to be a bottleneck, but Zigbee is the slowest communication protocol I know. One; it is suitable for some home markets, but it is not feasible in the commercial field. Zigbee may be used in some large buildings, but it requires a lot of manual support and customization, which is costly."

Mohan pointed out that if someone is using Wi-Fi network streaming, the Zigbee-controlled door may not be open. Users must confirm that each floor uses a different wireless channel: "You can't work with the current electrical technician. Selling such solutions because they are not proficient in RF technology."

He believes that Zigbee has not learned from the Internet industry, the current development requires too much manual support, and has not left the initial stage of adoption: "Lighting control solution providers do not understand the network security they need, this kind of communication agreement It will always be in a backward state; if system vendors such as Aruba and Cisco are to dominate Zigbee, they will find a way to run ahead."

Mohan also said that emerging alternatives such as 6LoWPAN are not ideal, because the Internet Protocol (IP) packet headers occupy too much bandwidth: "IP is not designed for low-bandwidth applications, so They are trying to revamp it to make it more efficient, but we need someone who can focus on the whole thing, maybe incorporating the new spectrum."

There are infinite business opportunities in the building control sector, and Mohan estimates that there are up to 80 million square feet of commercial space in the United States, compared to two to three times the global market. Considering that the market will have a new round of demand growth, Enlighted raised $20 million in funding about nine months ago: "We need to grow explosively in the next few years."

Enlighted has a number of large established competitors in the market, such as Lutron and WattStopper, now owned by Legrand, the world's largest electrical contractor; the company hopes to gain an edge in motion sensor data collection and analysis. Mohan exemplifies that if the projector in the conference room does not know where to go, Enlighted can provide an animation of the movement of the device in the building to help determine who took it: "This is our exclusive technology."

Enlighted is currently working on new applications, such as HVAC optimization from existing user analytics; the company also plans to establish a new strategic alliance in 2015. Enlighted started with the power line network, Ethernet and 802.15.4 wireless network to build the building control network. Later, it found that the power line and the Ethernet were high in cost and power consumption, so they gradually became the main force. Placed in the 802.15.4 wireless solution.

The need for more bandwidth has prompted Enlighted to develop its own protocol, using Atmel's integrated 15.4 chip with its own digital signal processing software. Mohan said that the amount of data they collected was much higher than expected, but it also proved that the 15.4 wireless solution rate can exceed 250 kbit/s, so they developed their own wireless communication technology; now the company is waiting for some kind of The solution can solve the interoperability problem of the Internet of Things. No matter who wins, they are ready to upgrade.

Solar Charge Inverter

Saintish Solar inverter with MPPT ranges from 1000W to 3000W, which is a new type of multi function inverter /charger, combining functions of inverter, solar charge controller and Battery Charger to offer uninterruptible power.
The off grid solar inverters are with pure sine wave output to protect electronics and the real MPPT increases around 30% of solar panels output.

The inverter charger comes with protection of over charge/discharge, over load, short circuit, battery reverse, solar reverse, etc.
