ZigBee And Z-Wave, Which Is Better?

There has been an ongoing debate between which technology is the best overall solution for Home Automation: ZigBee or Z-Wave? Obviously one will win but can we predict which one?
                                                              
According to the ZigBee Alliance, ZigBee Home Automation offers a global standard for interoperable products. Standardization enables smart homes that can control appliances, lighting, environment, energy management and security as well as the expandability to connect with other ZigBee networks. On the other hand, Sigma Designs explains Z-Wave as a wireless RF-based communications technology designed for control and status reading applications in residential and light commercial environments. Target applications for Z-Wave are home entertainment, lighting and appliances control, HVAC systems and security.

Comparison

As one can read in the introduction, both technologies address similar environments and applications. Let’s dive into the details in order to find out the differences, as well as the pros and cons of using each technology.

PHY and RF
The first obvious difference is in the physical layer. Z-Wave took the Sub-1GHz approach, which has superior range versus the 2.4GHz approach of ZigBee. However, Sub-1GHz home automation requires different SKUs for different regions. How many? Well it depends – for Australia and Brazil this is 921.4MHz, China and Singapore at 868.4MHz, Russia at 869MHz, India at 865.2MHz, U.S. at 908.4MHz and Japan at 2 other bands. So there is no “one product fits the whole world” solution as there is with the ZigBee Home Automation.

Z-Wave uses frequency-shift keying (FSK) modulation. ZigBee is based on direct sequence spread spectrum (DSSS) which is a more advanced and robust modulation.

Available Silicon and SW
When it comes to availability of silicon and software, there is a huge difference between ZigBee and Z-Wave.

ZigBee chipsets are developed and manufactured by multiple silicon vendors including Texas Instruments, Atmel, Silcon Labs, Freescale, STMicroelectronics and more. Whereas, Z-Wave products are only manufactured and sold by Sigma Designs.

If we compare packaged modules – the picture is the same, multiple ZigBee module makers vs. very few of Z-Wave.

When it comes to software, there is even a bigger gap. ZigBee software has multiple vendors. Larger silicon manufactures will develop their own software and provide that to their customers.

Protocol aspects
Both ZigBee and Z-Wave are supporting mesh network topology, which is a strong requirement towards the revolution of “internet of things”.

The number of nodes of Z-Wave product is limited to 232 (theoretically), however practical use cases will support a 10 nodes network. The number of nodes you may support with ZigBee network is 65,000 (theoretically), however practical use cases support a 500 nodes network. IEEE 802.15.4 networks (the foundation layer of ZigBee) can practically support thousands of devices.

Interoperability is a big issue. The Z-Wave protocol is not open, and can be provided only under licensing with Sigma Designs and can only run on their silicon receivers. The Z-Wave devices will interoperate well with similar Z-Wave devices. The challenge is the limited set of devices and architectures you can support. ZigBee on the other hand, as an open industry standard, will allow interoperability with any ZigBee certified device. ZigBee has defined several profiles per market segments. The ZigBee Home Automation standard is fully interoperable with a variety of devices such as door locks, sensors, alarms, smoke detectors, blinds, motor control etc.

Why Apple Lost in The Next Generation of Smart Devices Trend?

   
  From the beginning of CES , smart home and smart devices such as wearable technology sector has become a hot topic . As a technology industry giant, Google ( microblogging ) from the beginning of last year have continued to acquire a range of intelligent hardware and robotics company , great action . In contrast, Apple is still focused on the iPhone and iPad, why ? Since 2012 , Google, Sony and Samsung and other giant company has launched its own intelligent hardware products, like Nest, Smarthings, Pebble, Fitbit and Withings and other entrepreneurial companies compete launched its own smart home products and wearable devices. In this wave of smart home and intelligent hardware , Apple is still waiting for the right time.

  Current intelligent hardware market is still small , not worth the apple to enter :
       For Apple billions of dollars in annual revenue this enterprise is concerned, only concerned about the scale of tens or even one hundred billion U.S. dollars in the market ; present intelligent hardware and smart home market is still in its early stages, nowhere near the scale of smart phones , tablets and PC markets.
       For example, Control4, listed companies in 2013 in terms of the current market value less than $ 500 million in 2012 revenue is only about $ 100 million . If the sum Nest, Control4, Withings, Fitbit, Pebble and a series of intelligent hardware startups valuation estimate has not yet reached $ 10 billion .
   So Apple is not currently into intelligent hardware and smart home market is not surprising. Instead, Apple showing great interest in the automotive market

  Apple's energy is limited, still focus on its core products :
       According to Apple January 28 morning released the 2014 first quarter financial results , iPhone revenue ( $ 32.4 billion ) accounted for total revenue ( $ 57.6 billion ) of 56%. Exposure to cash flow so to force the product , Apple should put in more effort to ensure its leadership in intelligent machines and other advantages of the product.
    With the mature form of intelligent machines , Apple increased pressure in terms of innovation , need to put more effort and money to ensure the leading position in product innovation. In this context , a number of acquisitions to integrate Apple into the iPhone 's technology companies, such as speech recognition company Siri, chip design company Intrinsity, 3D sensor company Primesense, processor and fingerprint Company Passif Semiconductor Company AuthenTec.

 Apple is not the best Internet companies :
       Apple is an excellent combination of hardware and software companies, but not a great Internet company . Flex is absolutely world-class experience for Apple , but Apple has yet to find the internet service feeling , with Google, Facebook and others have not a small gap .
       Apple itself has recognized the shortcomings in this regard in recent years, mergers and acquisitions will be a series of mergers and acquisitions in some excellent Internet startups . For example, Apple in recent years has acquired five maps ISP , trying to catch up with Google Maps service . In addition, in recent years, Apple has acquired social data company Topsy, personal search companies Cue, mobile data compression company AlgoTrim, application notes and video recommendation service companies Catch Matcha.
       It can be predicted that Apple will continue to make up its ability to provide Internet services in the above deficiencies through acquisitions, narrowing the gap with companies such as Google and Facebook will integrate its own core Internet services to iOS systems go.
       
Apple also need a healthy ecosystem , rather than doing everything yourself :
       For Apple, iOS system built on APP Store is at the core of its ecosystem , Apple will attach great importance to maintain the APP Store ecosystem , will not easily be made to stimulate and harm developer behavior.

     Of course , a relatively large market potential for smart watches and smart auto market , Apple has some action ; while for intelligent hardware is still early , wearable devices and smart home products, Apple will be more patent and technical reserves, will not easily introduction of end products. It is reported that , in the smart watch , Apple already has hundreds of people in a day and night of R & D is expected to be released within 1-2 years .

A Patent of Home Automation Comes to 180 Billion!

  At present, home automation has become the global hot spot, and national governments and enterprises treat home automation as a key developing object in succession. Home automation will become one of the applications in smart Earth and IOT (Internet of things) in China. At the beginning of this year, Google took over Nest, and the whole world meets with a wave of home automation and enterprises at home and abroad keep a close watch on this hot application and begin to release the plan of smart home development.
IOT (Internet of things) is also called sensor network in USA. Its basic operation principle is that a mass of sensors detect the various status data of the environment anywhere, anytime and continuously, and then transmit the data to cloud server to analyze them, in order to decide whether intervene the environment, which will be a comprehensive and large-scale active intervention to our living space for the first time in human history, and it will create a burst of global innovation.
    Essentially, IOT is the combination of virtual economy and substantial economy and it features with development in several fields at the same time. After 30 years of reform and opening up, China has become a global manufacturing power and after 20 years of the development of Internet, China has cultivated massive Internet genius. The above two characteristics have laid the global foundation of the development of IOT in China. From the point of the development of global IOT, developed countries and China are basically in the same starting line, and in particular, China has guided the global development in certain application field. With the continuous development of China economy, China will form a huge market and surpass developed countries. Before the arrival of next consumption wave, whether Chinese has made preparation means a lot.
To exceed western countries economy ultimately, China should rely on innovation. According to modern commercial codes, intellectual property is the powerful weapon to protect innovation. Whether Chinese enterprises have the awareness of intellectual property, and whether they can keep continuous innovation and the awareness of intellectual property rights protection in the home automation could be particularly important.
According to the information published by National Patent Office, the patent we can find that involved home automation is quite limited, among which, utility model patents with low value occupy the largest share. However, it’s worth mentioning that the leader of home automation – Nanjing IOT Sensor Technology Co., Ltd. has achieved 9 national invention patents, among which, high value patents awarded by National Patent Office account for a huge share. And several patents are worth special mention. It is well-known that, all traditional house appliances adopt IR remote control and this method has covered almost every family. Then how to realize the automation of house appliance without replacing them, IR control comes to the sole choice or the exclusive entrance of the automation of traditional house appliances. To control house appliances remotely via mobile phones can be realized by a patent called “Wireless IR Transmitter” invented by Nanjing IOT Sensor Technology Co., Ltd. involved in this area. Namely, controlling traditional house appliances by transferring wireless signals into IR signals by any other companies constitutes infringement. This patent owns a huge market – if a family has 2 air-conditioners and 1 computer, it means every family needs 3 IR transmitters. Considering there are 300 million families in China and if one transmitter sells at 200 RMB, this IR transmitter has a market size amounted to 180 billion RMB.
Another patent by this company called “Wireless Cloud Smart Lock” is also amazing. The smart lock at present market is the intellectualization of single product with just fingerprints, passwords, cards, keys to open the door at a close range. Nevertheless, With the Wireless Cloud Smart Lock, users can open the door remotely via mobile phones, which not only avoids the inconveniences caused by keys, but also improves the home security greatly. What’s more, Nanjing IOT also owns some high value invention patents, such as “Wireless Cloud Drawer Lock” related to home security closely, and “Wireless GPS” that can realize the real home automation. These patents of this company prevent from foreign enterprises’ entrance to Chinese home automation market. The characteristics of IOT wave that distinguish the traditional industries such as the industrial revolution and Internet revolution is relying on invention patents instead of price war. But what is even more remarkable is that all these patents have been developed into actual products which have been sold to domestic and foreign markets. Obviously, Chinese enterprises have beaten western companies by making full use of western thought.
The development of an emerging industry relies on the guide of the government and the support of the society. From the national level, Chinese relative management department should preserve the innovation awareness and protect the intellectual property of our enterprises in the emerging industry like home automation field, so that the whole society will protect and encourage self-innovation, which will lay a solid foundation for our countries to compete with western developed countries in this emerging industry wave.

2013 Shanghai Intelligent Building Exhibition was held on 25th, Sept to 27th, Sept. Many professional home automation exhibitors participated in it, such as KNX, Z-wave Alliance, Enocean, C-bus. And several ZigBee manufacturers like Wulian and Control 4 took part in as exhibitor as well.

There are visitors from more than 50 countries coming for this Expo. Russia government organized a delegation with more than 100 businessmen to visit.

At Wulian smart home’s booth, more than 100 pieces of products was displayed and many of them were available for function demonstration at scene. Wulian smart home aims at bringing intelligence as well as fun to people’s daily life. To achieve this goal, a D-I-Y notion is planted into its products. D-I-Y style means that home automation products should like general merchandise in supermarket, from purchase, deliver, installation to function setting, all things can be easily done by end user. No professional knowledge and skill are required during the whole process. People will buy home automation products like they buy a tooth-paste. By providing diverse products from lighting management, appliance control, security protection to environment surveillance and health service, Wulian smart home gives consumer extensive device choices and allows them to set all kinds of function combination according to own needs. For example, end user can choose to link curtain with light sensor to realize an automatic indoor light management, or choose to connect motion detector with lights to achieve light’s on when people passing and light’s off when people gone.


During the whole Expo, more than 200 batches overseas customers visited Wulian smart home booth. Canada, Indonesia, Russia and Iran customers had signed distributor agreement at scene.


Is Home Automation Ready for Prime Time?

   
  
Home automation products have been featured at CES, well, ever since there was a CES. I’ve seen all sorts of products like the X-10modules that turned appliances on and off and dimmed lights and the Insteon system of switches, dimmers and even sprinkler controllers.

These early lines of product have their place — back in the eighties I had about a dozen X-10 modules all over my house — but aside from geeks like me, most people didn’t bother to adapt the technology even though it was affordable and easy to find at Radio Shack.
At CES we’re seeing a number of home automation products that take advantage of the near-ubiquity of WiFi to move data around the house and  smart phones and tablets as controllers.
I spent some time at the Belkin booth looking at their new  line of modular home automation modules. These products are still in development, but they’re quite promising. The devices, which require that you have a home WiFi network, can be used to turn appliances on and off, let you know if you left your garage door open (and let you close it) or respond to motion in the room.

Each device communicates to the Internet via WiFi and can be controlled via any iOS device (the company is also developing Android software) from anywhere on the planet.  A company spokesperson told me that modules can also be programmed to turn on and off at specific times or after a specific amount of time.
Wulian supply the whole set of home automation,and find distributer all over the world.
