Wi-Fi已将通信速度，范围和集成的界限推向了诸如较低功率和新协议功能之类的功能，并增加了无线应用程序的数量。根据Wi-Fi Alliance的说法，今年将使用近180亿个Wi-Fi设备，并将在2022年发货44亿亿个设备。Wi-Fi通常用于消费者，工业和企业应用程序以启用无线的无线应用程序设备与云之间的连接。
Wi-Fi可以在智能建筑物的视频仪，HVAC和访问控制产品中找到；医疗保健中使用的患者监视和医疗设备；网格基础设施采用的智能电表和太阳能/可再生能源系统；还有更多需要连接到互联网的产品。
Why is your Wi-Fi connection so important and why does it matter if it’s fast and strong? Because we rely on it to remain productive and innovative. Bottom line, though, we simply need it to work no matter what.

With more people and things becoming connected than ever, Texas Instruments’ (TI) goal is to provide the freedom and flexibility to connect anything. If you’re developing a product with Wi-Fi connectivity, you need a reliable and tested Wi-Fi device to ensure that your product will connect in any environment.
That means fast speeds and reliable internet connection all of the time. TI has been one of the leaders in Wi-Fi solutions for embedded devices for more than a decade. Its product range of SimpleLink Wi-Fi chips and MCUs offer a wide range of choices and options. What’s more, TI Wi-Fi devices implement robust security features without any burden on the main MCU, enabling secure cloud-connected IoT applications.
Of course, when tech companies say your data is in the cloud, they mean it’s stored somewhere (in many somewheres, actually) on the internet, instead of locally on your computer. A network of web servers will find what you’re looking for and deliver it.
SimpleLink Wi-Fi wireless microcontrollers (MCUs) are used as the main host to enable cloud connectivity. All are proven, tested, and adaptable for high-performance and/or low-power, security-enabled IoT applications.
该公司对无线连接如何允许我们快速适应和保持生产力的看法更全面地说明有关TI为确保其Wi-Fi解决方案的作用的文章。
基于软件和硬件的安全
消费者希望使用其连接的设备获得最佳的用户体验，以便他们可以通过Internet安全传输数据而不会中断通信。为了实现这一目标，开发人员需要设计具有良好Wi-Fi连接性的物联网产品，并实施将保护最终用户隐私的安全措施。
为了保护最终用户的资产，Ti的SimpleLink Wireless MCU集成了许多基于多层软件和基于硬件的安全功能。这样的工具有助于保护您的产品免受本地数据包的嗅探，中间服务器的仿真，通过播放（OTA）更新的敌对收购，远程文件操纵，数据和软件盗窃，知识 - 秘密（IP）克隆， 和更多。
SimpleLink Wi-Fi CC3X3X和CC3X20设备提供了有效的内置安全功能，而无需在主MCU上进行任何处理负担，从而可以开发安全的无线和云连接应用程序。安全功能包括安全存储，安全的内容交付，与云的安全连接以及硬件加密加速器的使用。此外，这些设备符合FIPS 140-2验证的一些最高安全性（FIPS是联邦信息处理标准）。
Providing Reliable Performance
Some of the important factors when choosing a connectivity device is the Wi-Fi device's ability to provide reliable performance, security, and a high level of worldwide interoperability. The reliability of a system is defined as the probability that a system, including all hardware, firmware, and software, will satisfactorily perform the task for which it was designed, for a specified time, and in a specified environment.
当它快速可靠时，无线连接可以帮助您完成一些非常惊人的壮举。就可靠性而言，TI的Wi-Fi芯片组可以在具有障碍的不利环境中（例如在房屋或办公室）或工厂和医院（例如工厂和医院）中的障碍物（例如在房屋或办公室）或高度拥挤的环境中进行设计。它们适用于高性能或低功率，支持安全性的物联网应用程序。
The chipsets are designed to work outdoors as well as at temperatures above 85°C, making them suitable for use on the grid and for supporting infrastructure. This is due to robust radios with high RF performance, advanced features such as a proprietary network learning algorithm, and more. Resiliency is ensured with a comprehensive testing strategy, includinginteroperability tests across hundreds of access points(see figure)。这样一来，无论产品在世界范围内，它都可以正常工作。
TI投资了确保其SimpleLink和Wilink设备系列（Wilink是一种组合设备，支持蓝牙和蓝牙低能功能以及IEEE 802.11 a，b，g，g，g，g和n乐队，具有一流的阶层）稳定性和鲁棒性处理现实生活中的情况（请参阅表）。Stability testsvalidate that the device can function as designed for long periods without degradation in performance or interruptions in the service (for example, disconnections).
内置的简单性
Unnecessary complexity is one of the common mechanisms that can lead to electronics failures. In Wi-Fi, provisioning is the method that connects a device to a network. To simplify matters, a SimpleLink Wi-Fi device can be turned into an access point for a brief period of time where the embedded device is hosting a web server.
设备有所谓的网络处理器inside of it. This networking subsystem includes all of the provisioning. What that means is the host—i.e., the microcontroller, whether that's on a CC3200 or 3220 with the built-in microcontroller, or a CC3100 or 3120, which is connected to an external host like any of the CC26xx devices—is going to perform all of the steps needed.
Making the Move
So, let's get this party started: The SimpleLink Wi-FiCC3235 LaunchPadandCC3220 LaunchPad是从Simplelink Wi-Fi家族开始的最佳方法。CC32XX设备同时包括应用程序处理器和网络处理器。
SimpleLink Academy is another great starting point for developers to learn about the SimpleLink MCU Platform. SimpleLink Academy delivers easy-to-use training modules that span a wide range of topics for all LaunchPads in the SimpleLink MCU family. In addition, the E2E Wireless Connectivity forum is the go-to source for help in the design process.
