applications. Frequency hopping spread spectrum (FHSS)
technology ensures maximum resistance to multipath fading and
robustness in the presence of interfering signals, while operation
in the 900 MHz ISM band allows license-free use in the US,
Canada, South America, Israel, Australia and New Zealand. The
DNT900 supports all standard serial data rates for host
communications from 1.2 to 460.8 kb/s. On-board data buffering
and an error-correcting air protocol provide smooth data flow and
simplify the task of integration with existing applications. Key
DNT900 features include:
?
