A real WIFI base station should have the following most notable features:
1. Support multi-core and multi-band (2.4G and 5.1-5.8G), which can be used for WIFI signal coverage and long-distance transmission to meet different business needs and applications in various environments.
1. When doing WIFI signal coverage service, three or four cores can be applied in the 2.4G segment, and with different angle antennas, flexible signal coverage can be flexibly carried out on floor structures of different structures, so that the covered buildings The signal is at its best.
2. When you are away from the data exit and need to be covered by a WIFI signal, in this case, there is no good access point for upstream data, and it is impossible to go wired in the air. At this time, one core of the WIFI base station can be applied in the 5.8G frequency band, and then the WIFI base station CPE placed at the data exit position is connected to the data exit (can transmit 1-15KM), and the remaining two or three core applications are in the 2.4G band Do WIFI signal coverage. This can make the location of the WIFI base station more flexible, and can better meet the signal coverage of long-distance buildings. The cells around a data exit point can better extend the coverage of the coverage signal, and the simple device press and release can make the WLAN service coverage more extensive and greatly increase the user's access.
2. High bandwidth and high power meet the access volume of multiple users.
1. The high bandwidth of WIFI base station, the net rate reaches more than 50M. If a piece of equipment called a base station only has a net rate of about 20M, how can it meet the access of multiple users? If so, then only a large number of APs can be purchased, which is not simpler. We all know that if 1M of bandwidth is allocated to each access user of a base station, ordinary devices can only have about 20 users, which is no different from APs. Such a device can only be called a pseudo base station. The bandwidth of the real base station is 2-3 times higher than that of the AP to meet the access of a large number of users, and the number of users around the base station can be met without adding equipment.
2. The general residential or office building structure is relatively complicated, blocked by 3-7 layers of walls. According to the attenuation principle of wireless transmission, a layer of ordinary wall will attenuate the 3DBI signal (that is, half of the total output power of wireless equipment), and the power is small The device often has no signal after passing through the first and second floors. Real WIFI base stations can use the high power (1-5W) dry discharge, so that after penetrating the third floor, the terminal device can also receive The signal allows users to access the Internet normally. In this way, users can be better served without adding equipment.
None of the above functions are possessed by single-core devices. In addition, the WIFI base station software has better expansion performance, and can be better connected with the equipment room.
