Detailed Description
Embodiments of the automated wireless network selection platform of the present invention will be described in detail below.
WIFI is a technology that allows an electronic device to connect to a Wireless Local Area Network (WLAN), typically using the 2.4G UHF or 5G SHF ISM radio frequency bands.

In addition, FLASH memory chips are nonvolatile memories, and blocks of memory cells called blocks can be erased and reprogrammed. The write operation of any FLASH device can only be performed in empty or erased cells, so in most cases, the erase must be performed before the write operation can be performed. While it is simple for a NAND device to perform an erase operation, NOR requires that all bits in the target block be written to 0 before an erase can be performed. Since erasing NOR devices is performed in blocks of 64-128 KB, the time for performing a write/erase operation is 5s, whereas erasing NAND devices is performed in blocks of 8-32 KB, which requires only 4ms at most to perform the same operation. The difference in block size when performing erasures further increases the performance gap between NOR and NADN, and statistics show that for a given set of write operations (especially when updating small files), more erase operations must be performed in NOR-based cells.
