![]() ![]() Radio Wave Transmissions: – Radio waves can penetrate through objects.Does not penetrate walls – Disadvantages:.Does not interfere with other communications signals.Infrared Transmissions: – Can send data by the intensity of the infrared light wave – Light spectrum: All types of light – Infrared light: Can be used for wireless transmissions – Emitter: Device that transmits a signal – Detector: Device that receives a signal – Advantages:.IEEE 802.11g IEEE 802.11n expected to be approved by 2008 IEEE 802.11 Specified that wireless transmission could take place via infrared (IR) or radio signals.Since late 1990s, IEEE has approved four standards for wireless LANs: It looks like they will move this standard along much more rapidly with approval before the final approval date of October 2008 on the current IEEE timeline found on their website. ![]() The first question that will be asked by letter ballot over a 15 day period is "Should 802.11n Draft 1.10 be forwarded to Working Group letter ballot as Draft 2.0?" If this question passes by 75% or more then a second question will be asked by letter ballot "Should 802.11n Draft 2.0 be forwarded to Sponsor Ballot?" If both of these pass by 75% or more then on the IEEE will start moving the Draft 2.0 towards a standard. ![]() What is the rest of the process to get this to be a standard?

Question: Mike – before we get into the technology…. In this podcast we take a look at this new draft standard and also look at earlier standards including 802.11 a, b and g. ![]() Intro The IEEE 802.11 Working Group on January 19 unanimously approved a new Draft 2.0 802.11n proposed standard. ![]()
