Chipsets Improve City Efficiency

City efficiency is an important factor for measuring a city's success. More and more cities are deeply integrating technologies like big data and AI within a range of fields to get more out of their resources at lower costs. We provide solutions including PLC-IoT chipsets and 5G NB-IoT chipsets which enable cities to remotely control resources such as energy and commercial displays, which is easier and more efficient.

5G NB-IoT Smart Meter Solution

Throughout history, energy has played a key role in the development of society. Today, new technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI), have given rise to smart energy, which is transforming the traditional energy sector. These new technologies let us monitor and manage networked energy devices, so we can reduce energy consumption and use energy more efficiently. For example, by digitalizing gas and water meters and reorganizing them into networks, we can read meters remotely, which is more efficient and accurate. Additionally, measures such as tiered fees can be applied for meters which are read regularly, promoting energy conservation and efficient use.

Remote meter reading can be implemented through methods such as wired communications or unlicensed spectrums, but each of these brings a unique set of challenges. In wired mode, signal cables need to be used, which are difficult to implement. If unlicensed spectrum technology is used, signals are vulnerable to interference, and can easily be shielded by a house's structure, which leads to low success rates when reading meters.

NB-IoT is a low-power, in-depth coverage technology that improves signal coverage by up to 20 dB and is perfectly suited to the reading of water and gas meters. NB-IoT is a key 5G mMTC technology, and because it adheres to the 3GPP standard, it is more likely to support long-term technological evolution, making it the best communications solution for smart meter reading.

HiSilicon Boudica is a widely used NB-IoT chip which supports NB-IoT modules with standard interfaces from various vendors. It has been applied to tens of millions of smart meters.

The Boudica 200 chip has the following advantages:

  • Excellent performance: Features ultra-low power consumption and high sensitivity. Supports 3GPP Rel-15 and later protocols, offering stable communication connections for smart gas and water meters.
  • Flexible integration: Features a built-in RF and PA and integrates the iSIM function. This design greatly reduces the size and cost of modules and provides a more flexible integration solution for smart meters.
  • Easy maintenance and testing: Supports the Bluetooth low energy (BLE) and global navigation satellite system (GNSS), enabling comprehensive local maintenance and high-precision positioning for smart gas meters.

Commercial Displays Make Intelligence Accessible

Commercial displays are applied across many industries, from the all-in-one touchscreens used for self-service in stores, to the LCD billboards fitted in elevators, and the interactive whiteboards used for remote conferences. As more and more of these commercial displays appear, requirements become increasingly diverse. That's why we have launched our commercial display chip solution, which provides multi-core heterogeneous computing, ultra-HD audio and video signal processing, and a range of input and output interfaces. With this solution, our customers have the power to create truly innovative commercial displays.

  • Audio and video: With the powerful built-in CPU, GPU, NPU, 4K/8K codec, professional ISP, and premium audio DSP, it's no wonder that HiSilicon commercial display chips have been used in everything from electronic whiteboards to laser projections. Our chips deliver powerful CPU and GPU performance, robust compute capability, and concurrent task execution, and they can be used for 4K video transfers and 4K UI display. They also support up to 8K@120 Hz hardware decoding, which makes decoding both efficient and lossless, with latency of less than 20 ms. As if that wasn't enough, they pack gigabit and PCIe interfaces and provide diverse network access modes, including Wi-Fi, BT, 4G, 5G, and G.hn. This enables customers to achieve high-speed, low-latency network transmissions, and ensure end-to-end transmission quality.
  • Flexible customization: Our commercial display solution allows customers to create various apps more efficiently.
  • Easy interaction: Displays have been enhanced with features such as voice input, handwriting, one-click sharing, free projection, and flexible file editing, to actively engage users.
  • Cross-device collaboration: HiStreaming is a technology we developed to enable displays to quickly identify and connect to peripheral devices. It can also extend compute capability by connecting with compute sticks, providing consumers with the ability to collaborate seamlessly across devices.
