Most of the embedded computer has additional upper-layer software components in addition to the core operating system and these components consists of networking protocol stacks like TCP/IP, FTP, HTTP, and HTTPS and they are all included in the storage capabilities like FAT and Flash memory management systems. The 2.4GHz band wireless device has basically two main ranges and they are 802.11b using DSSS which would be direct sequence spread spectrum with speeds of up to 11Mbps and 802.11g using DSSS which would be at speeds of less than 20Mbps and OFDM which would be orthogonal frequency division multiplexing for speeds above 20Mbps up to a maximum of 54Mbps. The ISO 15693 is a RFID transponder and is compliant and it is designed especially for applications which would require a rugged up RFID transponder and can completely withstand all the harsh environments. This RFID transponder would basically meet all the requirements in terms of heat, pressure and chemical resistance in the application like contact less tracking of garments in the textile industry and dry cleaning.
