The maximum range of each standard varies, depending on environmental factors such as obstructions and interference from other sources of radio frequency signals. The maximum range of 802.11a wireless was approximately 95 feet with throughput of up to 54 megabits per second, while 802.11b was capable of transmitting up to 150 feet at 11 Mbps. The 802.11g standard extended that range to 170 feet at the same speed as 802.11a; 802.11n extended the maximum range to 230 feet and throughput to a maximum of 600 Mbps. 802.11ac routers provide similar range but increase throughput to a theoretical maximum of 1.33 gigabits per second. So depending on the environmental factors and antenna setup / placement, will determine the best possible output of your wireless router.
