MediaFLO – ICC-1001 Tester – Tester ICC China
About FLO "in MediaFLO means Forward Link Only, meaning that the data transmission path is middle of the tower to the device. The MediaFLO system transmits data on a separate frequency spectrum used by existing mobile networks. In the United States, the MediaFLO system uses 716-722 MHz spectrum, which was previously assigned to UHF television channel 55. FLO was standardized in ETSI TS 102 589 that, and standard components within the Telecommunications Industry Association (TIA 1099, 1102, 1103, 1104, 1120, 1130, 1132, 1146 and 1178.) MediaFLO is a competitor of the Korean T-DMB, 1Seg Japanese and European standards DVB-H. Qualcomm MediaFLO also conducts technical studies at International, with the intent to form alliances with content providers and operators of multi-channel service. Protocol technology has been developed because of the inherent inefficiency spectral Unicast full-motion video, high speed multiple subscribers. In addition, the analog television signals traditional air-ground digital television (DVB-T) are difficult to implement in mobile devices, mainly due problems of energy consumption. ATSC, used only by the States United States and its neighbors, also have difficulties even with fixed reception due to the multiplicity and mobile ATSC-M / H (which is the TV stations free of personal air) was not completed in 2008.
In addition, the transmission is not necessary to send a higher resolution would be needed to screen greater. MediaFLO streams are only 200-250 kbps, which would be insufficient for the size of the larger screen. In the United States today requires FLO is transmitted by a network of high-power transmitters operating in the effective radiation power of up to 50 kilowatts. This allows an area coverage of an issuer to be as large as 3040 km. Activation of several of these transmitters have been delayed because of the official end analog TV Channel 55 is delayed. Immediately after the transition, the FLO network has been extended to several new markets, and coverage has improved in some existing ones. Transmission Encryption is a set of QAM OFDM signals transmitted over a channel of 5.55 MHz to 716-722 MHz (UHF TV channel 55 ex.) The group has been auctioned off by the FCC and known as the Lower 700 MHz D. Block Qualcomm has purchased an auction later, using the old analog UHF television channel 56 (722-728 MHz) in Boston, Los Angeles, New York, Philadelphia and San Francisco for additional services, however, this show is owned Wi-Fi (a subsidiary of Frontier Wireless Dish Network) in most of the other media markets, where ATSC-M / H are signs in the air. All transmitters send the same signal and use the same frequency, forming a single frequency network. This allows the mobile to decode the signal to a transmitter in the same way that perhaps if she was a multipath-delayed version of the same issuer. All stations use WPZA237 indicative, but each has an identifier indicating the group and number. For example, a station on the media market Metro Atlanta is ATLAN6, while another is ATLA14. Some of MediaFLO other operating parameters are: the value of the parameter Total number of sub-carrier QAM Number 96 4096 Number of subcarriers guard subcarriers 500 drivers Multicast logical channels (MLC) 1-7 uses QPSK modulation (4 symbol constellation), 16QAM (16 symbols) Distance between 1.355 kHz subcarrier (5.55 MHz / 4096 subcarriers) modulation symbol (chip) duration of 0.18 s (1/5.55 MHz) Any holder (data) traffic occurs in a MLC using the 3500 subcarriers not general. The protocol also provides for a certain period of time between symbols, so that effects of multipath transmission and reception. Total OFDM symbol interval parameter (TS) 833.33 bearer traffic data (TU) s 738.02 window Range (TWGI) 3.06 s cyclic prefix (TFGI) 92.25 s there a time window TWGI includes both before and after each OFDM symbol. However, since this window is shared between every two consecutive symbols, TS = + UT + TWGI TFGI. Channels In the United States, all television providers FLO offers a set of 13 channels Base: 2.FLO (6:00 to 10:00 p.m.) the original reports for mobile and concerts; added at the beginning of 2010 ABC CBS mobile phone contains a mixture sports and other content CNBC CBS Comedy Central ESPN Mobile TV frequent simultaneous sporting events live from their family networks Fox News Fox Mobile NBC 2Go Mobile Channel MSNBC MTV A mixture of MSNBC, NBC, CNBC and Bravo networks Disney Channel, Nickelodeon programming 24 / 7 more children, FLO Preview Channel is a channel free-to-order Barker, available for free subscription. For conditional access, Verizon Wireless is using its EVDO network to authenticate devices mobile and provide the decryption keys necessary to decode programming. For this reason, users who use the data block to avoid unauthorized charges are also prevented from seeing the tracks, including the overview of the channel. There are 16 television channels broadcast by Verizon. Additional channels include Verizon: Adult Swim (10:00 p.m. to 6:00) MTV Tr3s TLC Adult Swim 2.FLO part time, as it does on cable TV with Cartoon Network. There are 15 channels television broadcast on AT & T: AT & T exclusive channels: CNN Mobile Live YouTube showing a variety of devices, including devices MediaFLO first film by LG and Samsung at CES 2006 in Las Vegas. December 1, 2005 Verizon Wireless and Qualcomm announced a partnership to launch the MediaFLO network, Verizon and launched commercial service in connection with its offering VCAST March 1, 2007, the marketing of MediaFLO technology or services as' VCAST TV. "A similar ad was made by AT & T Mobility in February 2007. AT & T Mobility launched its MediaFLO service May 4, 2008. The first devices, not just your TV were released in late 2009. FLO TV is offered for the first time on some wireless phones offered by Verizon Wireless and AT & T Wireless. In November 2009, the FLO TV presents FLO TV devices personal mobile TV (PTV-350 model). Measure 3 inches by 4.4 inches by 0.5 inches and weighs just over 5 ounces, has a 3.5 inch screen capacitive touch. Users control the device with sudden intuitive gestures. oleophobic glass lens maintains Display 3.5 inch QVGA crystal clear. It was first offered by Amazon.com, Best Buy, Radio Shack and other select retailers. As the battery life is relatively long, which offers five hours of listening time and 300 hours standby, personal TV FLO TV can be used for display on long trips or extended. FLO TV is available in new cars through partnerships with manufacturers because specific and can be integrated entertainment system in a car. It can also be added to existing vehicles with systems that can be installed by professional installers. vehicle systems are manufactured by Audiovox.
