cell phone jammer can block external communication of the participants

Nokia, Samsung, Siemens has released a new smart cell phone that supports RS MMC card, and it is expected that in future will be broader support. This is equivalent to only a credit card size pluggable devices can be plugged into a computer or Pocket PC. The PC card according to their thickness are classified as a Type I, Type II and Type III three models. PC Card devices will be plugged into the Pocket PC data storage or communications functions (for example, to connect the telecell phone line or LAN). History: MMC card SANDISK Corporation, USA and Germany's Siemens in 1997 developed a versatile memory card. Reflow oven machining will be performed forcell phone jammer .
Features: MMC card is a 7-pin interface, mainly used in digital cameras, cell phones and PDA products, the price is relatively expensive. MMC card to a certain extent to improve the shortcomings of the CF card read and write slower, and is lightweight with dimensions of 32mm × 24mm × 1.4mm and weighs less than 2 grams. Impact resistance, can be repeatedly read and write 300,000 times. MMC Card 4.0 standard provides a wider data bandwidth and faster transmission rate, and supports dual voltage operation mode. In the 52MHz × 8-bit mode, data transfer rate up to 52MB / s,. Relative to the sd card: retained due to the subsequent launch of the SD card standard equipment on the MMC card compatible. The serious one will generate electrostatic spark which may detonate the inflammable gas without installingcell phone jammer .
Therefore, although the device using the MMC card can not use the SD card, but use the SD card device can easily use the MMC card, Pretec has announced the advent of the MMC4.0 standard speed 2GB MMC memory card, making the capacity of the MMC card Start close to the CF card. Prospects: developed by Hitachi card RS-MMC (Reduced Size of the MultiMediaCard, the smaller size multimedia card). MMC card was very small on the basis of shape just half of the MMC card, the length of more than half the length of the MMC card point (the MMC length of 32mm, the length of the RS-MMC is 18mm). MMC card can also be used as a dedicated adapter installed in the back. More in line with today's mobile digital age, smaller size, lighter weight, larger capacity need. DCS is one of the signals which will be shielded bycell phone jammer. cell phone jammer can block external communication of the participants in the meeting room
MMC card brands on the market today are more, such as sandisk, kingmax TEC, PQI, PDI, DEC, Nplus etc., and quality can not just look at the brand as a brand with poor products, but also a superior product. The key is high compatibility, the MMC where PQI is the cheapest price, so now more PQI brand of products, of course, fake it more, now on the market PQI MMC card, there are two, one is the generation of low-speed blue dolphin cards, this blue card up to fake, not to buy. The second is the orange card, if you have to buy the PQI, recommended to buy the orange card.
