Yes. Wireless is still possible for you, you just can't use cheap home equipment. You should look for a networking consultant in your area that specializes in 3com or other name-brand equipment that can get you set up with a much more professional class wireless setup. The equipment will be more expensive, but it will also be more reliable and more secure.
