ZigBee: Problem child or future success?

Image

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.

Image

Lots of cities in the world, such as London, have a very famous reputation of being chilly. But just as the fog may roll, the sun can indeed shine, too. For one lucky London home, the family members stay happy year-round while the home itself does all its adjusting automatically.

Gretchen’s home installed Wulian’s home automation system one year ago. They loaded the residence with smart-home essentials like lighting control, entertainment, data networking, shades, security, and remote access control. But this system also boasts features specifically added to keep the climate as comfortable as possible, no matter how cold—or hot—it may be outside. Naturally, the home’s heating and cooling systems are integrated into the Wulian smart home system. But a few fancy flourishes go beyond the basics when it comes to keeping comfortable. In the main living space, a modern fireplace sits in a partial wall between the living room and a family room. Any time the weather gets a bit chilly, any family member can crank up the gas fireplace using their Wulian smart home system. Instant inferno. And what if that center star of the solar system decides to make an appearance? On the back patio, a large mechanical awning expands and retracts on command, adding a Shangri-la of shade at a moment’s notice. Very cool, indeed.

Wulian smart irrigation: just like Nest for the garden

Image

It’s starting to feel like the Internet of Things (IoT) train is finally leaving the station, as more and more household appliances become Internet-connected with a smartphone app providing the User Interface/remote controller.

Taking cues from the same IoT playbook is Wulian Smart Home with its “cloud smart irrigation”. It’s set out to bring the garden sprinkler kicking and screaming into the Internet age, replacing what is either a “dumb” device or one that, whilst Internet-connected, is crippled by a clunky User Experience.

Current irrigation controllers are outdated, extremely unintuitive and frustrating to use. Wulian’s irrigation system is connected to weather data, so when it rains the controller will stop watering without a manual shut-off. And when you have a sunnier day than expected, the controller will automatically water plants according to soil’s humidity without being turn on by people”.

Apart from toilsome manual operation, traditional irrigation also brings too much water wastage in the process. And in turn, unnecessary expense. To solve this problem, Wulian smart irrigation, via its cloud-connectivity, is powered by location-based weather data. In addition, and taking a page straight out of Nest’s book, it’s self-learning, resulting in a claimed “up to 50%” reduction in water consumption.

Since the advent of the smartphone, home automation technology is booming indoors and accessible to the masses. The same need for automation exists in the yard. Therefore, Wulian develops a simple App supporting both IOS and Android to realize a remote control and scheduling. It also learns and improves over time, conserves water, saves money.

Integrate Your Energy Conservation with Home Security: Tips for creating summer savings by Wulian Smart Home

Image

Home automation systems are not only a great way to ensure the utmost in home security, but also provide valuable savings for homeowners, particularly during the summer months.

Wulian’s home automation system can be accessed through a number of devices, including smartphones and tablets, giving users the peace of mind to know a home is not only secure from intruders, but is also well-maintained in other areas.

Here is a list of tips for using Wulian Smart Home that will enable user to not only enjoy security system benefits, but also have a more efficient home.

1.During the day, when at work or other activities, leave the air conditioning off, and using a home automation system, turn it on before arriving home. This will lower utility bills because the system won’t be running all day when no one is home, but will still be cool when the home’s residents do arrive.Image

2.If on vacation, instead of leaving outdoor lights on throughout the duration of the vacation, use a home automation system to turn lights on at sunset and turn them off at sunrise. Not only will this save on utility bills and help reduce carbon footprint, but it will also appear more realistic when trying to persuade a burglar that someone is present in the home.

3.When on vacation, many homeowners try to deter burglars by leaving devices such as televisions on. Instead of leaving the television on for the entire vacation, use a home automation system to turn the TV on or off at random, which will save electricity and dissuade would-be burglars from targeting a home.

4.Program home automation systems to control sprinklers and other irrigation devices. Often, during the hot months of summer, homeowners will leave their sprinklers running unnecessarily. By programming sprinklers to turn off at a certain point, a homeowner can save money and water at the same time. If on vacation, it can also be a good idea to run sprinklers occasionally, to give burglars the signal that someone is home.
