Analyzing the Cost of Wireless Bridges from Wireless Bridge Hardware and Software
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.
