Before  you  lift  a  finger  towards  the  perfect  wireless  installation,  think  about  the  impact  of  wireless  communications  on  your 
application.  Acceptable bit  error  rates  are many  orders  of magnitude  higher  than  wired communications.  Most  radios quietly 
handle error detection and retries for you - at the expense of throughput and variable latencies.  

Software must be well designed and communication protocols must be tolerant of variable latencies. Not every protocol can 
tolerate  simply  replacing  wires  with  radios.  Protocols  sensitive  to  inter-byte  delays  may  require  special  attention  or  specific 
protocol support from the radio. Do your homework up front to confirm th

at your software won‟t choke, that the intended radio 

is friendly towards your protocol, and that your application software can handle it as well. 

Assumptions:  

 

No RF retries.
