Steel back boxes limit?

Looking to have some network points put in.
Will need 25mm steel back boxes. Is there a limit to how many can be chiselled into the wall before affecting the structural integrity.
One wall near the window will have 2 2g and 2 1g installed near enough next to one another. Does that sound safe?

A solid brick wall in good condition can withstand several metal back boxes being installed without affecting the wall strength. like most things you need to check, if while you are chasing the back boxes out you notice large cracks appearing this may indicate either the plaster has blown or the wall may be moving slightly. it may be better to get it checked before carrying on.
