A Bluetooth gateway is an electronic device that connects a Bluetooth product to other hardware. For instance, an audio or stereo BL gateway connects a Bluetooth-enabled device to an external speaker. In this article, our focus will be on a cellular BL gateway. Cellular BL gateways converge cellphone accounts with home landlines.

Today, we have an assortment of wireless protocols so that it might become a little confusing to check them all. On one hand, it is helping developers of wireless technology to address specific issues in design. On the other hand, it also makes identifying the right protocol a bit different task. It becomes particularly true when we have to choose between BLE (Bluetooth low-energy) and Bluetooth Classic. A person who is not a tech expert may assume BLE and Bluetooth as the same devices. However, it is crucial to know the differences, advantages, and disadvantages of all options to choose a perfect Classic or BLE gateway.

The Skullcandy Indy ANC is the pinnacle of the Indy true wireless family, and it is powered by MediaTek Airoha. Loaded with top tech, it has Digital Active Noise Cancellation with up to 32 hours of battery life and wireless charging case with rapid charging that gives 2 hours of play from just a 10-minute charge. The Indy ANC’s lag-free connection allows full media controls on each bud. And, a ‘tap and hold’ Ambient Mode that switches off ANC to let you easily engage with the world around you without having to remove the bud.

刚进入6月，俄罗斯气象局就曾报道，在北极圈内的维尔霍扬斯克附近记录到的地面最高温度达到48摄氏度。如此高的地表温度意味着气温至少有三十度以上。而这只是全球气候变暖的一个缩影。

二氧化碳排放犹如被打开的潘多拉魔盒，暴雨、山火、气候变化、海平面上升等一系列的蝴蝶效应随之而来。现在，如何关上这个“魔盒”，成了环境课题的重中之重。

7月16日，全国碳排放权交易正式开市，掀起了“碳中和”的又一轮热潮。众多企业围绕碳中和提出了全新的战略目标，碳中和概念股成为耀眼明星，有股票因切中“碳中和”概念，连续21天涨停。不少和碳中和概念相关的上市公司也被调研机构“踏破门槛”。在国外，更是有近百家互联网企业宣布了各自的碳中和策略。

小小的一个“碳”，影响着每家企业的战略，也牵动着每一个普通人的心：我们究竟可以为碳中和做些什么？

Satellite navigation has revolutionized the way we get around. It’s cheap, fast and easy to use. But there’s one fatal flaw in the system: It simply can’t work underground.

GPS requires line of sight to satellites orbiting the planet. The great advantage of this is that it works seamlessly all over the world, without needing to be connected to a cellular or Wi-Fi network. This works well in open areas but in built-up areas with tall buildings, or in underground tunnels, the system can fall apart.

Bluetooth beacons offer a great opportunity for many industries to work more efficiently and improve their offering to customers. One of the most interesting applications is in the world of retail, where the phrase ‘know your customer’ is taking on a whole new meaning.

Mesh networking with Bluetooth has a bright future. By taking advantage of existing lighting systems you open the door to huge added value possibilities, both for your business and its customers.

While mesh networking is nothing new, it is only now starting to be adopted in industrial and commercial environments. Bluetooth Mesh offers a low power mesh network with the potential to deliver many and varied added value services.

Some people in the industry view mesh networking as the next ‘shiny object’, nothing more than another excuse to raise prices. But mesh does deliver significant benefits over star or peer-to-peer networks and looks set to make a real impact on the industrial IoT and in the smart home in the years to come.

The reason is simple: mesh networks solve a specific problem. A conventional wireless router offers limited coverage if you can’t hardwire additional access points to it, which drives up complexity and expense in large spaces such an office building. On the other hand, mesh networks bring wireless connectivity to such a space far more simply than ever before.
