另外，大家请在一周之内私信找我，否则奖品作废。




Zigbee3.0，这个名词对于大家来说是否陌生呢？

很多人可能会说，我认识Zigbee！但是Zigbee3.0听说的就少了。

近年来随着物联网技术的不断发展，物联网通信协议也在不断地变化，

Zigbee3.0是Zigbee联盟发布的最新的Zigbee标准， 今天我们就和Qorvo一起来学习一波Zigbee3.0！



其实，在我们社区，流传着一个非常古老的资料，那就是WiFi之父写的Zigbee白皮书。什么，你说你不知道？

马上上链接！Qorvo白皮书之--Power of Zigbee3.0

本期活动我们就围绕这本白皮书展开！

活动规则：

阅读本帖中的白皮书，由于是全英文的，需要大家对白皮书进行翻译，翻译的内容根据前一个人的内容进行接力~也就是说，第一个回帖的将会是翻译第一段或者是第一句话的！我们对翻译长度不做要求，大家可以翻译几句话，也可翻译一句话，只要不出现翻译半句话的情况出现即可。

凡是按照规则回复帖子的同学，都有机会获得管管设置的奖品哦~

活动时间：

8月10日~8月31日

活动奖品：

奖品来啦~


一等奖：小米智能摄像机X1


二等奖：sony 入耳式耳机X1


三等奖：罗技无线键鼠套装

还等啥~快来参加翻译接龙吧~

The Power of ZigBee? 3.0
All about the new and improved ZigBee 3.0, and what smart home and IoT devices development decision makers need to know

开发者需要知道所有的ZigBee 3.0的新内容和改进内容，和智能家居物联网设备的发展。

As the Internet of Things (IoT) market accelerates and becomes more of a reality, the hype surrounding it becomes more intense and more confusing. It is time for a reality check to take inventory of where things really stand, and to make some assessment of where things are going. Some confusion has been cleared, some confusion has exacerbated – but let’s start with what has simplified.

随着物联网（IoT）市场的加速并变得更加现实，围绕它的炒作变得更加激烈和混乱。 是时候进行现实检查，清点事情的真实情况，并对事情的进展情况做一些评估。 一些混乱已被清除，一些混乱加剧了 - 但让我们从简化的开始。

Radio Technologies

无线电技术

Two years ago there was a lot of discussion about the different radio technologies that would be useful for the IoT.
Some companies advocated that Wi-Fi and Bluetooth? would be sufficient, while other companies were starting to push IEEE 802.15.4 (the underlying radio technology for ZigBee and Thread). Actually, the majority of today’s networking technology decision makers are now comfortable with and fully understand that the IoT will use all three technologies for different applications.

两年前，有很多关于对物联网有用的不同无线电技术的讨论。
一些公司主张Wi-Fi和蓝牙?就足够了，而其他公司则开始推动IEEE 802.15.4（ZigBee和Thread的基础无线电技术）。 实际上，今天的大多数网络技术决策者现在都很满意并完全理解物联网将把所有这三种技术用于不同的应用。

To address the weakness of Wi-Fi (compared to ZigBee), an activity was started to standardize low-power Wi-Fi (IEEE 802.11ah). Although activities in this area are still proceeding and may lead to a standard, worldwide acceptance is very doubtful. This standard is not universal, because we will have different specs and flavors in different regions in the world. Adding to the challenge is the fact that, even though this new low-power standard is called Wi-Fi, it does not have any compatibility with “real” Wi-Fi. It is a completely different radio and MAC technology. So why not use IEEE 802.15.4, which is already a universal standard and provides all the features the developers of this new low power Wi-Fi is struggling for? This new flavor of “Wi-Fi” does not make much sense.

为了解决Wi-Fi的弱点（与ZigBee相比），新的标准化低功耗Wi Fi（IEEE 802.11Ah)已经开始制定。虽然这一领域的活动仍在进行，最终可能会推出一个标准，但世界范围内的接受度是非常值得怀疑的。这个标准并不是通用的，因为在世界上不同的地区有不同的规格和特性。最关键的是，尽管这个新的低功耗标准被称为Wi-Fi，但它与“真实”的Wi-Fi没有任何兼容性。这是一个完全不同的无线电和MAC技术。如果这样的话,那我们为什么不使用IEEE 802.15.4呢，它已经是一个通用的标准，它提供了这个新的低功耗Wi-Fi开发者的所有特征？这种“Wi-Fi”的新特性没有多大意义。

Bluetooth, as an IoT standard, has a critical weakness – it was designed as a point-to-point cable replacement technology, not a networking technology. To address this weakness, some companies have started to work on a network layer for Bluetooth (“Bluetooth Mesh”) but they face serious challenges. Previously, many industry networking engineers have seen similar mesh networking attempts fail. For example, IEEE 802.11s exists but is hardly used, and implements only a single hop mesh topology (repeater). The key problem is that latency cannot be controlled when supporting multiple hops. So, the skepticism amongst network technology engineers around the new Bluetooth Mesh story is really no surprise
作为物联网标准之一，蓝牙有一个严重的缺点——它被设计成点对点电缆替代技术，而不是网络技术。为了解决这个缺点，一些公司已经开始为蓝牙(“蓝牙网格”)开发网络层，但是他们面临着严峻的挑战。此前，许多行业网络工程师尝试类似的网状网络均以失败告终。例如，IEEE 802.11s虽然存在，但很少使用，并且只实现单跳网状拓扑(中继器)。其关键问题是，当支持多跳时，延迟无法控制。因此，网络技术工程师对新蓝牙网格的商业前景的怀疑并不奇怪。

So, bottom line, the worldwide wireless market has accepted three core IoT radio technologies: IEEE/802.11/Wi-Fi for content distribution as we are all familiar with today; IEEE 802.15.4/ZigBee for sentroller networks like smart homes; and Bluetooth, including Bluetooth Low Energy, for connectivity, personal area networks (around the smartphone) and wearables. The first two connect devices in your home to the internet; the last one mainly uses the smartphone for internet connection
总而言之，全球无线市场已经接受了三项核心物联网无线电技术: 我们已熟知的用于内容颁发的IEEE / 802.11 / Wi - Fi；适用于智能家居等传感器网络的IEEE 802 . 15 . 4 / ZigBee；蓝牙，包括用于连接、个人局域网(智能手机领域)和可穿戴设备的低功耗蓝牙。前两项将您家中的设备连接到互联网；最后一项主要用于智能手机的互联网连接。
