1898 蓝牙

随着物联网（IoT）的普及，无线技术仍然是电子行业的焦点。
今天，我们有两个来自供应商的项目，这些项目一直领导着蓝牙和天线相关产品。
蓝牙5于2016年6月正式宣布。在该公告中，据透露，蓝牙5的两大特点是数据速率提高（蓝牙4.2的两倍）以及增加的范围。
不幸的是，我们不能吃蛋糕，也不能吃。
这两个新功能是互斥的。
这意味着在增加的距离上无法实现加倍的数据速率。
事实证明这适用于大多数物联网应用程序。
在这方面，我强调的第一个产品是Dialog Semiconductor的蓝牙5开发套件（1564-1050-ND）。
Dialog以低功耗解决方案而闻名，该套件也不例外。
它配备了蓝牙低功耗主板，DA14585子板，迷你USB电缆和CR2032纽扣电池。
该套件非常适合熟悉蓝牙5和物联网应用的快速原型设计，例如：遥控器，接近标签/跟踪器，信标，连接医疗设备，智能家居产品，VR控制器，无线充电和连接传感。
我想介绍的另一个产品是Johanson Technology的天线（712-1589-1-ND）。
由于物联网设计往往偏小（物理上），天线通常最终靠近电池或金属电池座。
这会干扰天线并使其无法预测。
这可能会导致设计时间增加和浪费金钱。
虽然市场上有各种各样的天线解决方案，但Johanson独有的这一解决方案的独特之处在于它对金属平面的需求减少了重新设计的麻烦。
谢谢观看！

With the proliferation of the Internet of Things (IoT), wireless technologies remain a focus in the electronics industry. Today we have two items from suppliers that have been leading the charge in Bluetooth and Antenna related products.
Bluetooth 5 was officially announced in June of 2016. In that announcement, it was revealed that the two big features of Bluetooth 5 are an increased data rate (twice that of Bluetooth 4.2) as well as an increased range. Unfortunately, we can’t have our cake and eat it too; the two new features are mutually exclusive. What this means is that the doubled data rate cannot be achieved over the increased distance. It turns out this is fine for most IoT applications. On that note, the first product I am highlighting is a Bluetooth 5 Development Kit (1564-1050-ND) from Dialog Semiconductor. Dialog is well known for low-power solutions, and this kit is no exception. It comes with a Bluetooth low energy motherboard, the DA14585 daughter board, a mini USB-cable, and a CR2032 coin cell battery. This kit is perfect for getting familiar with Bluetooth 5 and quick prototyping of IoT applications such as: remote controls, proximity tags/trackers, beacons, connected medical devices, smart home products, VR controllers, wireless charging and connected sensing.
The other product I want to introduce to you is an antenna (712-1589-1-ND) from Johanson Technology. Since IoT designs tend to be on the small side (physically), antennas usually end up next to a battery or metal battery holder. This can interfere with the antenna and make it act unpredictably. That can lead to increased design time and wasted money. While there is a wide array of antenna solutions on the market, what makes this one from Johanson unique is its requirement for a metal plane reducing the headache of a redesign.
Thanks for watching!
