If multiple access points are needed, it is necessary to ensure that each access point signal has 
an overlapping area, and each label is at least within the coverage of more than one access point. 
If there are walls, columns, air pipes, refrigerators, etc., between the access point and the label, 
the wireless signal will be affected and attenuated to a certain extent. When the access point  is 
installed, it should avoid the above objects as far as possible. If it cannot be avoided, it can be 
regarded as reducing the coverage radius of the access point. 
The signal frequency band of the ESL access point coincides with the band of 2.4G Wi-Fi. If 
the ESL access point and the wireless router are installed together, the two will interfere with each 
other, so the two should be installed separately. 
Actually, when installing the access point, we also need to consider the number of ESLs that 
the  access point  can support. Single SUNMI wireless access point for smart ESLs supports a 
maximum of 10000 pieces of ESLs. But considering the refresh speed of batch push and system 
redundancy, it is recommended that one access point be allocated for every 3000 pieces of labels. 
The installation distance between access points can be adjusted accordingly. 
3.2.3 Access Point Configuration 
After  all  ESL access points  are installed, it is necessary to use SUNMI  assistant APP to 
configure each access point, including the Internet access mode and name of each access point. 
After configuration, the tie-up  between  access point  and store will be completed to realize the 
networking of access point, so that the labels can be connected to the access point. 
Detailed configuration refers to the implementation process documentation of software
