VM-0217: In a wireless network, the transmission distance is 40 m Wuhan wireless router, concurrent customers 20, an antenna function is 5DB * 2, built-in firewall. Antenna can achieve the purpose of enhancing the wireless signal, it can be understood as an amplifier of the wireless signal. Antennas having different spatial directions different radiation or reception capability, according to a different directivity, and the directional antenna has two omnidirectional. Omnidirectional antenna: In the horizontal plane, and receiving no maximum radiation direction of antenna called omnidirectional antennas. Omnidirectional antenna due to non-directional, so much used in the central station-to-multipoint communications. For example, you want to establish a wireless connection between two adjacent buildings, you can choose this type of antenna. Directional antenna: one or more antenna radiation direction with the maximum reception called directional antenna. Directional antenna energy concentration, the relative gain omnidirectional antenna must be high, suitable for long distance point to point communication, and because directional, strong anti-interference ability. When such a district, across several floors need to establish a wireless connection, you can choose this type of antenna. Wireless Router: As a wireless antenna material change is relatively simple, but only a change of the material; and the choice of a good chip solutions and manufacturer of comprehensive strength is not able to get a couple of days, the program depends on the upstream chip manufacturers are not be able to support you, the availability of strategic support is critical to the major chip manufacturers, under normal circumstances, the world's leading chip manufacturers in the choice of partner when Wuhan wireless router, the requirement is very strict, not only to examine the equipment manufacturers themselves R & D level (including staffing levels, equipment level, system management, platform integrity, etc.), but also to examine the equipment manufacturers in the industry's position and market share, the number of visits down, usually Wuhan wireless router investment partners, only comprehensive up the best and promising to become the chip equipment maker's strategic partners. Therefore, the reference chip's support is very effective as a factor.
