Top 10 Countdown: Getting Wireless Covered
6/28/2005
- 802.11g is a short-range solution ideally suited to small indoor networks of heavy data users.
- 802.11b base stations can cover areas 25 times greater than 802.11g.
- Beyond 500 feet, 802.11b delivers a higher data rate and greater coverage than 802.11g, and 802.11g-only stops working entirely at about 650 feet.
To address dead spots, just add more access points.
- Not so fast! Because of co-channel interference, the additional APs may actually lower the range and/or data rate of nearby APs, or even cause new dead spots!
- Before adding more APs, consider: 100 percent coverage may not, in fact, be your objective.
To get outdoor coverage, you'll need a ton of access points.
- Not true. Wi-Fi hardware can easily provide 802.11b data rates out to 1.25 miles, for an area of 7.5 square miles.
- You can achieve wide outdoor coverage using a base station with multiple radios and high gain, directional antennas.
100 percent coverage should always be your objective.
- There are always overlaps and gaps that change as the network evolves.
- In adjusting power levels, and moving or adding APs, you may end up fixing one problem, but seeing another appear.
- 90 percent coverage may be all you need to provide full service to your customers.
