Wulian IOT Sensor Technology Co.,Ltd

Tobin J. M. Richardson, chairman of ZigBee Alliance, allegedly emailed a Chinese and English announcement to more than 400 ZigBee Alliance members and interested stakeholders on Oct. 20th, 2014, in which he claims that Chinese enterprise "Nanjing IOT Sensor Technology Co., Ltd." (hereinafter referred to as "Wulian Group") has been inaccurately and intentionally misadvertising its products as being "ZigBee Certified."

Now, this news has produced negative effects on Nanjing IOT Sensor Technology Co., Ltd. ("Wulian Group") and its partners. Therefore, Wulian Group hereto releases the following announcements:

1.      Wulian Group is the legal holder of the "ZigBee" trademark (Category 7, Category 11) recognized by Chinese Trademark Office (CTMO).

2.      Wulian Group has never publicized that Wulian Group's products have been certified by ZigBee Alliance.

3.      ZigBee Alliance established its "ZigBee Alliance China Regional Headquarters" in Wulian Group's Shanghai office in 2012. Wulian Group has never claimed that Wulian Group has represented ZigBee Alliance on any occasion. Wulian Group only has used the "ZigBee Alliance China Regional Headquarters" title in some promotional materials. We believe it's not improper to use the title, and Wulian Group has never received any written objection from ZigBee Alliance.

4.      Wulian Group will investigate the legitimacy of the ZigBee trademark on foreign products that have entered or will enter the China market, and will reserve the right of pursuing the protection afforded under China's trademark laws.

5.      Wulian Group demands ZigBee Alliance to withdraw the inappropriate remarks and eliminate the adverse effects initiatively.

Since this year, Mr. Osbourne, the chairman of ZigBee Alliance Board, and Mr. Richardson, the chairman of ZigBee Alliance have negotiated repeatedly on the promotion of ZigBee technology in the China market and the ownership of ZigBee trademarks with Mr. Zhu Jungang, the Co-founder & CEO of Wulian Group and his negotiation team. Wulian Group has emphasized several times that Wulian Group is willing to contribute to the global unity and authority of ZigBee trademarks. However, ZigBee Alliance allegedly insists that Wulian Group transfers the ZigBee trademarks to ZigBee Alliance unconditionally. This is unreasonable. Wulian Group thinks that these ZigBee trademarks are Chinese intellectual property acquired by Wulian Group as per Chinese laws via a legal way and in the country of China. These trademarks should belong to the enterprises, institutions, or alliances that are registered in China, or the branches that are founded by the Chinese relative authorities. However, this reasonable requirement was allegedly refused by ZigBee Alliance Board.

With the rapid development of IoT (Internet of Things) and the smart home industry, ZigBee technology is facing fierce competition from WiFi, Bluetooth, and other wireless technologies. Therefore, each ZigBee member company and related enterprises should unite and make full use of ZigBee technology to enhance market confidence in ZigBee technology. At this crucial market promotion moment, as the chairman of ZigBee Alliance, Mr. Tobin not only allegedly failed to concentrate on the strong challenge of Bluetooth, Wifi, and other technologies, but wasted precious time and energy in criticizing Wulian Group who has made great contributions to the popularization and promotion of ZigBee technology. For that, we are deeply confused and regretful.

As a company that has been dedicated to the research and promotion of ZigBee technology for years, Wulian Group is and will still be an important stakeholder of ZigBee technology. Wulian Group understands that the unity, authority, and uniqueness of the ZigBee trademark are very important to ZigBee Alliance member companies and other stakeholders. Wulian Group doesn't want to see the split of ZigBee supporters or any adverse information related to ZigBee since any damage to ZigBee's reputation will hurt Wulian Group as well. Wulian Group is still sincerely hoping that ZigBee Alliance will consult with Wulian Group and relevant Chinese government departments about the legal usage of ZigBee trademarks and product certification in rational methods. Wulian Group also hopes ZigBee product suppliers who plan to enter the Chinese market will use "ZigBee" marks with caution and contact us actively to discuss the authorization of legal usage of ZigBee trademarks in China. Wulian Group also welcomes ZigBee product suppliers who plan to enter the Chinese market to contact us and discuss the trademark usage authorization. Meanwhile, Wulian Group has appealed to Chinese Trademark Office (CTMO) and other related judicial departments to protect Chinese enterprises' legal rights, and make sure that intellectual property gets its due respect.

With the constant rise of new technology, global competition has become even more intense and complicated. Wulian Group is willing to cooperate closely with partners as always to make contribution to IoT and smart home development as well as intellectual property protection.

Wulian Group's Announcements Regarding the Statement in the Email from ZigBee Alliance Chairman

Wulian Group's Announcements Regarding the Statement in the Email from ZigBee Alliance Chairman

Patent Blazes the Path - Home Automation Giant Appears

Home automation has become one of the largest hot spot since this year. The top technology giant continues to make the power, and stimulate the market. No matter large enterprises or small ones are afraid to fall behind, so they rushed to the home automation industry, and even parts of the venture capital cannot wait to know the market completely, and invest in some young home automation enterprises. Therefore, home automation market is extremely hot now.

Let’s have a careful look at the development ideas of global technology giants. It is well known that they have possessed rich experiences of market competition since they’ve strived for so many years. They insist that thinking twice before leap, so they would never enter the market easily before thinking twice. Now, Google dare to take the lead in launching the war of home automation, not only because they’ve taken over home automation company – Nest Lab, but also they possessed many patents of home automation through acquisitions or purchase. What’s more, Apple, Samsung and Microsoft also prepared to enter home automation industry. They have investigated the market deeply and completed part of patents layout. Although they enter the market with different time, they have prepared for it. Apple possesses a lot of home intelligentization patents, and Samsung also possessed about 200 home automation patents. They’ve prepared to move on.

From the world’s leading institutions Thomson Reuters Intellectual Property Research Center survey data, showing that from the statistical results of the U.S. Patent and Trademark Office and the China National Patent Office have received the patents of home automation since 2000, Samsung has belonged nearly 150 items of patents. Sony owns 60 items, not the half of Samsung, Google and Apple rank the NO.16 and NO. 30. From these, we can see these technology giants have the profound and lasting idea and experienced measures in wireless home automation area. Just see the patents, the biggest three smart home leaders of the future are becoming more and more clear.

The date of Thomson Reuters also shows, Nanjing IOT Sensor Technology Co,.Ltd of China has submitted more than 100 patents and more than 100 utility model patents. And 8 patents and more than 100 utility model patents have been approved. Many of them value a lot, enough to be a strong barrier for the competitors to enter this field. It is understood that Nanjing IOT Sensor Technology Co,.Ltd not only actively overall arrange the patents in the field of smart home, but also researched more than 200 kinds of smart home products and more than 100 kinds of products are in volume production now. And they also deployed the world's largest chain of retail smart home network, creating a unique business model in this industry. They have become a worldwide highly influential company in the field of smart home.

As the journalists investigation, judging from these public information of the industrial and commercial registration, patent inventor, network information etc, this rapidly developing, very low-key and mysterious enterprises belong to the domestics, no signs of foreign participation. The enterprise with this background has a unique natural advantage in the Internet of things smart home industry based on the domestic development which have near connections to the station security. Obviously, with the patent escort, excellent products, domestic background of the three conditions, the figure of domestic smart home giant is looming.

The Smart Home, a long standing promise for over 30 years, is becoming a reality today. ZigBee has developed as the wireless communication technology of choice. Actually, ZigBee is the low-power wireless technology that complements WiFi technology to make our homes smarter, safer, more comfortable and energy efficient.

Before we start: What is this much talked about Smart Home, which tech-evangelists have been promising for many, many years? It is the automated home with devices that talk to each other and that can be controlled from a home dashboard or with a smart phone over the internet. But until recently, the Smart Home always stayed upscale market or was the playground for a few hobbyists and early innovators.

The potential for mass market home automation has been recognized for a long time, and finally today we are witnessing the beginning of that new era with many large operators, service providers and utilities launching Smart Home applications. These can be managed via set-top box or gateway via the web, allowing subscribers to convert their households into state-of-the-art machines that can be monitored and controlled from anywhere in the world via smart phones, tablets or mobile devices.

The Smart Home is not built overnight

My experience shows, that a Smart Home will not be built overnight, but it will arrive in phases. Operators are starting to offer Smart Home applications as additional service to their current offering of TV, phone services, internet and entertainment; their customers can chose from applications that are tailored to their specific needs. A single home owner has different requirements to make his home smarter than elderly people or a family with children. These applications can check and control “things at home” such as temperature control (changing the setting of the thermostat), security (making sure that doors are locked), alarm systems (sensors and cameras) or energy management (e.g. lighting controls) and health and status monitoring of elderly people. To have all these different applications interoperable, they all need to be able to communicate with each other.

Why do we need industry standards?

Think of our own home: many of our home electronic devices, sensors and appliances exist on isolated islands, disconnected from the internet and unable to see or talk to each other. This has been a major obstacle for Smart Home adoption. The first requirement for Smart Home applications is to make them wireless (ease of installation) and maintenance-free (no battery replacement).

The wireless residential applications prosper best within the context of open communication standards, and offer OEMs the freedom to purchase from a large pool of suppliers and, most importantly, allow devices from different vendors to interoperate, which is paramount in the market success of integrated Smart Home applications and will increase customer adoption when consumers can buy devices from different brands.

The interoperability offered by ZigBee allows for all Smart Home applications to operate under the same open ZigBee communication standard. The different sensor applications and the devices they control are integrated and link their intelligence to create what I like to call the “Really Smart Home” which now no longer needs human intervention. This Really Smart Home integrates all applications and the intelligence behind it in one application layer, where the same motion sensor used in the security system to trigger an alarm, is also integrated in the light control and HVAC system that switches off the lights and the heating when nobody is in a room.

ZigBee or WiFi?

For the home environment, the immediate question is: Which networking will be best used in the home? One may think that WiFi and ZigBee are competing with each other. The reality, however, is that both technologies have their own place.

WiFi has been developed with a focus on a high speed data rate (100 Mb/s and beyond) to optimize the distribution of content through the home: from browsing the internet to downloading movies. WiFi connected devices are typically connected to the mains power and energy consumption has only been a secondary criterion.

ZigBee is complementary to WiFi: developed for sense and control networks, where battery life was the primary development factor; therefore the battery life of ZigBee devices can easily be measured in multiple years, or even exceeds the life time of the device it is used in. This is all in contrast to the battery life of even “energy efficient” WiFi implementations, usually expressed in weeks or months.

With its comparable indoor range ZigBee is the low-power version of WiFi and for me it is the clear technology of choice for Smart Home applications.

From the Smart Home to the Internet of Things

I consider ZigBee as the crucial enabler for the development of the internet of things. Most of the end-nodes on the internet today are people using PCs, laptops and smart phones. However this is rapidly changing as many more devices in the home are getting connected to the internet, building the Smart Home, and starting to shift the balance away from people towards connected things. These devices are usually sensors, controllers, actuators or combinations. For instance: a thermostat senses the temperature, essentially “sentrols” it, via its communication with a higher layer control system that is also connected with other systems, knowing the time of day, the outside temperature, etc. The Smart Home will accelerate the use of sentrollers beyond the home as well: in building automation, for the smart grid, and from there in logistical, industrial and agricultural applications.

Just like WiFi was a real milestone in starting the use of internet at home, ZigBee will be the trigger point for the Internet of Things, starting at home as well and enabling the next wave in the ongoing technology revolution.

Zigbee: Problem child or future success?

While successful wireless standards such as IEEE802.11x, GSM and Bluetooth, have been relatively easy to sell, bringing standardisation into the realms of more straightforward, low data rate, communications is significantly tougher. Within this environment, the efforts of the ZigBee Alliance to standardise network and application-support layers has, arguably, failed to make a convincing impression. Does ZigBee have a future?

The nature of RF design and the mentality of the typical RF design engineer being what it is, means there will invariably be a proprietary system that offers a better fit for a particular application. However, the attractions of standardisation for low data rate communications remain compelling. Chief among these being potential economies of scale, reductions in time to market, and opportunities to establish widespread ad-hoc interoperability.
ZigBee capabilities and opportunities

The ZigBee protocol is widely viewed as a companion to WiFi and Bluetooth, operating in the same 2.4GHz unlicensed radio spectrum and slotting-in neatly below Bluetooth in the power/data rate continuum. ZigBee also specifies the lower-frequency 915MHz and 868MHz unlicensed bands available in the Americas and Europe respectively. At 2.4GHZ, ZigBee provides 16 channels and supports a maximum data rate of 250kbit/s.

The standard is managed by the ZigBee Alliance, and takes advantage of the established IEEE802.15.4 PHY and MAC layers. 802.15.4 provides a convenient and robust radio specification, delivering benefits such as a straightforward power management strategy comprising fully operational and stand-by modes only. This provides the basis for very long battery lifetimes, which can be up to several years, while at the same time simplifying application design.

Yet some may view ZigBee as a problem child.

Currently, the majority of anticipated applications are in domestic controls and utility metering, as well as industrial, scientific and medical (ISM) equipment. To penetrate these applications, however, it must entice product developers away from the RF designs and supporting knowledge and IP embedded in existing products.

For example, a wireless key fob for a vehicle or garage door opener system may already be functioning satisfactorily using a proprietary standard in the 868MHz or 433MHz band. Migrating this to ZigBee would be a significant undertaking, only considered for a significant improvement in the product, such as improving security or tamper-resistance.

Developing with ZigBee and rivals

The ZigBee Alliance has defined standards from the network layer to the application support layer, which combine with the 802.15.4 lower layers to provide a complete wireless stack.

Semiconductor vendors such as Microchip, Atmel and Freescale have introduced complete modules for ZigBee development, comprising the 802.15.4 radio and ZigBee upper layers and integrating the microcontroller for ZigBee firmware and application hosting.

Using these modules, engineers are able to complete functioning designs without specialist design skills such as RF matching and board layout. Development boards supporting these modules provide a kick-start for application development. In fact, Meshnetics, which provides software development kits supporting hardware platforms from a number of vendors, claims a ZigBee network can be set up for evaluation within one hour.

But there are many other modules on offer to designers that provide the convenience of turnkey RF hardware design and an approved radio specification. Designers using 802.15.4 radio modules, for example, are free to use alternative upper layers, and the vendors of ZigBee modules provide the flexibility for designers to make their own choices. On the other hand, some silicon vendors offer complete transceiver modules based on proprietary radio specifications that are pre-approved to acceptance criteria in international territories.

The absence of any license fee is a major advantage to designers using proprietary products but, on the other hand, greater economies of scale may be available with a ZigBee-based system.
ZigBee strengths

As a managed standard designed to provide robust security features, allow large numbers of nodes, and support interoperability and vendor independence, ZigBee has convincing arguments in its favour.

It also embodies features that enable outstanding performance at relatively low power consumption. For example, support for multi-hop communications and flexible routing enable effective transmission distances to be extended beyond the single hop range of the 802.15.4 radio standard without resorting to increasing transmitter power.

Where the typical single-hop range is around 30m – but may be between 10m and 100m depending on environmental conditions, antenna performance and operating frequency band – the cumulative range of a ZigBee node can be extended to hundreds, or even thousands, of metres.

In addition, by supporting data rates up to 250kbit/s, when operated in the 2.4GHz band, ZigBee can deliver additional savings in transmitter power compared to networks using slower protocols.

In sensor networks, for example, where data collection rates may be comfortably inside this capability, ZigBee’s ability to complete data transactions quickly allows the transmitter to be powered off for longer periods. Since the power dissipated by the transmitter is largely independent of its operating speed, ZigBee delivers power savings by reducing the average energy per bit.

Compared with some proprietary systems, using a proven ZigBee module also helps with type approvals. The module vendor will already have overcome the majority of compliance hurdles, which effectively short-cuts a significant part of the approvals process. Alternatively, a significant number of proprietary offerings also carry relevant approvals.

An Achilles heel?

Designers, therefore, have a number of choices when selecting a platform for low data rate networking over long distances. The trend towards delivering the radio module as a complete module is quite commonplace among proprietary, non-ZigBee systems, as well as within the ZigBee environmen t. Although ZigBee is not the only system emphasising ease of design, the licensing structure maintained by the ZigBee Alliance adds to the cost of entry for ZigBee development.

Catalysts over the horizon

On the whole, ZigBee faces a tougher challenge to gain adherents than either Bluetooth or WiFi. Potential markets are diverse and also tend to be of lower total value. A number of well-established products are already in place, even though these do not offer the same potential for ubiquitous ad hoc interoperability. Moreover, the associated license fees remain relatively high.

It is worth remembering that the future of Bluetooth was in doubt for some time, until governments imposed legislation on the use of mobile phones in cars and in so doing kick-started the market for Bluetooth headsets. It is hard to imagine a likely legislative catalyst for ZigBee and a ‘killer application’ to drive mass adoption seems unlikely, taking into account the characteristics of ISM markets.

On the other hand, the standard is now widely understood, development platforms and silicon are readily available, and demand for wirelessly networked products in consumer and professional fields continue to grow strongly. If there are sound technical justifications for ZigBee, reducing the cost of entry may be sufficient to secure a successful future.
