About our headline feed

palowireless	Bluetooth and IEEE 802.11b Although aimed at different markets and roles, there has long been speculation about the effects 802.11b and Bluetooth have on each other, not just technical interference, but also whether they are in competition with each other commercially. Often these are simplistic press reports attempting to compare the two and seeking to decide a winner. This article however explains the similarities and differences between Bluetooth & 802.11b on a broad level and tries to show that there is no serious competition between the two. IEEE 802.11 Resource Center Wireless LAN news, tutorials, market research, tools, books, products and other resources.
80211Planet	Minimizing Bluetooth Interference (7/02) Bluetooth provides relatively low data rates for supporting short-range, wireless personal area network (PAN) applications. Bluetooth radios are starting to appear more often now in laptops, headphones, cell phones, and PDAs, which results in much less cabling for users to deal with. The deployment of both Bluetooth and 802.11 networks in the same area is a bit risky, though, because of the potential for interference. Similar to 802.11b, Bluetooth devices operate within the 2.4 GHz band. The difference is that that Bluetooth uses frequency hopping (at 1,600 hops per second) to hop over the entire 2.4 GHz band. 802.11b, on the other hand, uses direct sequence and only occupies approximately one third of the 2.4 GHz band. As a result, Bluetooth hops all over 802.11b transmissions.
BTDesigner	A comparison of Bluetooth and 802.11 (PDF, 2MB) This document provides a comparison of Bluetooth and 802.11. It provides information on forecasted markets, an 802.11 technical overview, OSI models, modes, features, international band plans, usage scenarios and interoperability.
EE Times	Conflicts between Bluetooth and wireless LANs called minor (2/01) Wireless Bluetooth links and 802.11b wireless LANs can clash, but the conflicts are within acceptable limits, according to tests from two systems makers. However, clouds still hang over the expected rollout of Bluetooth products later this year and some notebook makers said they will not build Bluetooth into their portables until 2002.
infoSync	Bridging Bluetooth and 802.11b (10/01) Many people seem to have the misconception that Bluetooth and 802.11b are competing standards - but in reality, they compliment each other. Wireless network access through the 802.11b standard, delivering a maximum transfer speed of 10 Mbps, has grown to become immensely popular both in workplaces, homes and as access points in hotels, cafes and other public hotspots like airports. However, Bluetooth, which only has a range of approximately 10 meters compared with 802.11b's approximately 300 meters (both best case scenarios), hasn't been greated equally welcome when it comes to establishing semi-permanent wireless connections to networks of various kinds.
Planet Analog	Bluetooth can coexist with 802.11 (2/01) Wireless solutions will not only need to provide seamless connectivity but since they will operate in the unlicensed bands, they will have to be robust to prevent potential interference. Interference resistance is going to be a "must have" feature for all radios that operate in unlicensed bands. But the problem is not the band-it's building the right solution.
WLANA	Reliability of IEEE 802.11 Hi Rate DSSS WLANs in a High Density Bluetooth Environment (PDF) The issue of coexistence between IEEE 802.11 high speed Direct Sequence Spread Spectrum (DSSS) and Bluetooth radios with both radio types located within a mixed environment is studied. A network topology, propagation model, and user traffic loads are postulated. The reliability of IEEE 802.11 Hi Rate DSSS radios is then estimated under the stated conditions.
ZDNet	Bluetooth vs. WiFi: Why it's NOT a death match (5/02) Does the world really need two wireless networking technologies? Bluetooth and WiFi (aka 802.11b) have both been much in the news lately. Of the two, WiFi got the fastest start. But Bluetooth is gaining traction in the marketplace; Microsoft, for example, has announced that it will build native Bluetooth support into a future version of Windows XP...
