• Step 1. Measure the building. • Step 2. Map out your stationary computer stations

(i.e., four-top tables and such). • Step 3. Compute your distances vs. bandwidth needs

(and remember to find out what's in your wall construction).

• Step 4. Check with your software vendors for any known "issues" regarding wireless transmission of their data. (This is not really a problem with anything in the last 3 years.)


106


• Step 5. Order hardware and assorted supplies. (Remember the assorted part.)

• Step 6. Pray to the gods of nerds and paychecks. • Step 7. Install. • Step 8. See step 6 again. • Step 9. Turn it on. • Step 10. Accept the praise of your colleagues and

patrons and that nice big new pay raise.
