33. Radio waves can be bounced around by many things, including walls, mirrors, water and metal surfaces. This can cause ?.
34. Each frequency _____ is divided up in to ____________.
35. The 2.4 GHz band has ____ channels.
36. All the channels available in a band are always available at any given time and in any given location.
37. The 5GHz frequency offers additional bandwidth over the 2.4GHz frequency
38. The 5GHz frequency is capable of carrying more non-overlapping channels which will result in less interference.
