Analyzing the Cost of Wireless Bridges from Wireless Bridge Hardware and Software
Posted on

The wireless bridge should not underestimate such a device. We always say that wireless transmission, and wireless bridge to achieve the function of wireless transmission, contains a lot of hardware and software. While the wireless network bridge of Leian has always been considered expensive by some customers, then we look at the hardware and software. Where is our wireless network bridge?

1, components
We use brand new brand components and quality assurance. The cost of components is not cheap. If there are very cheap wireless bridges on the market, don't they need to think about costs? For cost reasons, most of the components used are used or recycled components. This quality is worrying.
2, the circuit design
The wireless bridge circuit is also very critical, so Leyan is doing a good job of circuit design without compromising costs. The low-end prices are reduced from the periphery of the circuit design, resulting in less than the target, and there is actually a greater difference. Equipment is easy to fault.
3, chip
A chip in Lean's wireless bridge will do a corresponding matching software to ensure that the device can play a good role in ZUI. A chip is only based on a platform to play a big role.
4, the antenna
We all know that the wireless bridge transmission is through the antenna. How the comprehensive index of the antenna directly affects the transmission effect of the wireless bridge. Its indicators include: antenna gain, VSWR, frequency band division and so on.
(1) Relatively speaking, the gain of the antenna is high and the farther the signal can be transmitted. The antenna gain of low-end wireless bridges is generally not high. For the sake of cost, copper antennas are not used at all, but instead of aluminum plates or more materials, the gain that can be achieved is not high. And the quality will not be good. The Lean's all use copper antenna arrays to protect the antenna's effective gain.
(2) Standing wave ratio
This is also a factor that affects wireless bridges. If the VSWR is higher than the normal index, the RF current cannot fully transmit the electromagnetic wave to the distant place. Causes RF current to flow back into the circuit. The time is too long and the motherboard launches high, posing a risk to the stability of the entire system. The Lean's antenna VSWR is around 1.5, which is a standard.
(3) Lean adopts the antenna spread spectrum technology. Our antenna focuses on some bands and optimizes the gain of other bands so that the device can achieve a good ZUI gain. The antenna band optimization of low-priced products did not do well. The signal strength varies greatly.

The above is our starting point from the technical point of view, analysis of the cost of wireless bridges starting from what aspects. For the sake of the stability of the entire project, do not be coveted for a moment to be cheap, leaving behind countless worries.

Titanium Dioxide(TIO2)

Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.

It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.

Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
