One Beacon Type or Many?

Most beacon deployments use just one beacon type which has the advantage of easier administration in that all beacons are set up in the same way. However, if you are willing to forego that convenience then you might find a mix of beacon types might suit your deployment better. 

Some examples:

• All your beacons don't need to be waterproof if you only need a few to be outside. 
• You might need long range 100m beacons in only a few select locations.
• You might need a few beacons with a long battery life for those placed in inaccessible places.
• You might need inexpensive, disposable beacons in places where they might be stolen or go missing. Alternatively, you might choose a beacon that's made for screwing to a surface.
• You might need USB powered beacons where they are going to be heavily used (e.g. connected to) and where battery power will be insufficient.
• You might only need sensor beacons in a few places.
• You might use an Eddystone-URL beacon near the entrance to a site to promote app downloading.

One beacon doesn't always fit all circumstances, even within a single deployment and sometimes leads to compromises. In such scenarios, consider a mixed-beacon type deployment.
