Unformatted text preview: ELEN 557 01-13-2011 802.11n has MIMO i can be CLAfilFIED A5 4G The a. X b: C notation helps identify what a given radio is capable of. The first number (a) is the maximum number of transmit antennas or RF chains that can be used by the radio. The second number (b) is the maximum number of receive antennas or RF chains that can be used W by the radio. The third number (glis the maximum number of data wands?» s the radio 70741. Milan «are - MAX WWW/T. can use. For example, a radio that can transmit on two antennas and rece1ve on three, but can only send or receive two data streams would be 2 x 3: 2. The 802.11n draft allows up to 4 X 42 4. Common configurations of 11n devices are 2 X 22; 2 X 3: 2, and 3 X 3: All three configurations have the same maximum/)Q throughputs and features, and differ only in the amount of diversity the antenna systems provide. In addition, a fourth configuration, 3 X 3: 3is becoming common, which has a > ,HcLoté'P/lmfl 1") higher throughput, due to the additional data stream. @115 1W ’“wgmsw c001"l> 3e A Data Rate Mb/s flow Ir’ Em'e' 20 MHz channel 40 MHz channel 60W t“ 800ns Q 400ns Q 800ns Q [400ns G_ I (77/715) [—0— 1 flZZF‘SKh/z 6.50 7.20 [13.50 15.00 _.

Depending on the environment, this may translate into a user throughput (TCP/IP) of 100 Mbit/s.” "MIT and a medical center based in Alabama are beginning to deploy faster wireless 802.11n access points from Cisco Systems Inc. In more than 100 buildings on MIT's Cambridge, Mass., campus, as many as 3,200 access points running older 802.11a/b/g protocols will be replaced with 802.11n devices in the next 12 to 16 months, said Chris Murphy, a networking engineer at the university. Murphy said MIT, with more than 10,000 students and 11,000 staff members, has a "very, very wide variety" of client devices, from handhelds to laptops. Many of the laptops probably support the 802.11n protocol, he said. Some MIT staffers have been using voice-over-IP wireless handsets and have experienced poor coverage with the older Wi-Fi technology, but they said they have had full signal strength within the range of the new 802.11n access points, he added. With 802.11n, the university could eventually provide lP television, which requires a lot of bandwidth, Murphy said.” ELEN 557 01-13-2011 5:Z'< \A In Praev space ProEEQ‘HOIA W D 2?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
