What is the difference between "home-grade" Wi-Fi and "industry-grade" Wi-Fi?

From a micro perspective, Cetron's friends made four differences:

1. The difference in signal coverage

2. The difference between networking and operation and maintenance

3. Appearance difference

4. The difference between demand and cognition

1. The difference in signal coverage

Wi-Fi is an electromagnetic radiation, and the influence of electromagnetic radiation on human health has been widely debated.

The home environment is a place where people live 24 hours a day, focusing on health and comfort; the business environment in which “industry-grade” equipment is located is where people work, with more emphasis on efficiency and performance. In a commercial environment, many high-power devices are used, and extensive deployment is used to improve Wi-Fi coverage. In a home environment, signal coverage and green health must be balanced.

At the same time, we also found that in the domestic environment, the obstacles blocking the transmission of Wi-Fi signals are mostly cement partitions and even load-bearing walls. In the business environment, the obstacles that block the transmission of Wi-Fi signals are mostly wood board or glass partitions. Especially in the villa-like home environment, the barrier to Wi-Fi signals is usually larger than the ordinary business environment.

Therefore, in the home environment, multi-point deployment should be used as much as possible to improve the coverage effect. For each AP, it is necessary to control its transmission power to meet national standards and reduce the impact on the human body.

Cetron's home Wi-Fi solution features multi-point deployment features and refined RF control. While deploying multiple APs, reduce the wireless transmit power of each AP to one-tenth of the national standard.

■ The empirical values ​​of 2.4 GHz electromagnetic waves for penetration loss of various building materials are as follows:

□ barrier of partition wall (brick wall thickness 100-300mm): 20-40dB;

□ Blocking of the floor: 30dB or more;

□ wooden furniture, doors and other wooden partitions block 2-15dB;

□ thick glass (12mm): 10dB

2. The difference between networking and operation and maintenance

Whether it is a "home-grade" network or an "industry-level" network, the core is networking. There is an old saying that is good: "The sparrow is small and complete." As long as it involves network networking, there will inevitably be a combination of multiple network devices and seven levels of network technology. Common medium and large-scale home networking devices include routers, switches, PoE, wireless control, and APs. These network devices provide basic access support for home information systems through reasonable combination planning and configuration management.

These products and technologies have mature applications in the industry market, but there are two problems in the home environment while applying these products and technologies:

1. Poor environment in the computer room: In the domestic environment, although the living is comfortable, the constant temperature and humidity protection of the professional computer room is usually not available in the place where the equipment is placed. Even some places are not even placed, and the equipment is often piled up. On the balcony, or behind a cabinet.

2. Lack of professional management personnel: home environment, and no professional network management and operation and maintenance personnel.

For a home Wi-Fi network experience, there are five types of products. There is no place to put it, no special person to manage and maintain, and the natural end result is not ideal.

Customers want both the home networking effect and the simpler the better. It is best to solve all the problems with one device, and the entire network management and maintenance should be as simple and straightforward as a TV or microwave oven.

"Industry-level" products and solutions are used in home environments where the core technology remains the same, but the product must be redesigned. In order to solve the problem of home networking and operation and maintenance, the Cetron solution has developed two typical functional features: “Slim AP Architecture” and “Quad One Controller”:

● Thin AP architecture: Independent hardware controller (AC) is adopted. No matter how many APs are deployed, unified management is automatically found, and no separate configuration is required for each device.

● Four-in-one controller: One device integrates PoE, router, wireless controller and switch from hardware. Complete integration between physics and software. Reduce product complexity and space usage.

With Cetron's home Wi-Fi solution, you can have both an "industry-level" experience and "home-grade" convenience, making professional wireless solutions as simple as microwaves and televisions.
