Up to 900 feet (275 m) Up to 160 feet (49 m)
5.5 Mbps
Up to 1300 feet (396 m) Up to 200 feet (61 m)
2 or 1 Mbps
Up to 1500 feet (457 m) Up to 300 feet (91 m)
Technical Specifications
Your wireless router uses a radio transmission technology defined by the Institute of
Electrical and Electronics Engineers (IEEE) called 802.11 Wireless Fidelity (Wi-Fi). This
standard is subdivided into distinct categories of speed and the frequency spectrum used,
designated by the lower case letter after the standard.
For example, your router supports both the ‘b’ and ‘g’ specifications. The 802.11b
specification transmits data rates up to 11 Mbps while the 802.11g specification transmits
data rates up to 54 Mbps. These are theoretical standards so your performance may vary.
The radio waves radiate out in a donut-shaped pattern. The waves travel through walls and
floors, but transmission power and distance are affected. The theoretical distance limit is
1,000 feet (305 meters), but actual throughput and distance varies.
Both standards operate in the 2.4 GHz range, meaning other electrical appliances also
might interfere with the router – televisions, radios, microwave ovens, or 2.4 GHz cordless
telephones. Therefore, positioning your router where it encounters the least interference
helps maintain a better connection.
