Adapter ExpressCard to CardBus

The ATA (Advanced Technology Attachment English) or PATA interface, originally known as IDE (Integrated Device Electronics) is an interface standard for connecting devices massive data storage and optical drives that uses the standard ATA derivative and the ATAPI standard.

ExpressCard is a hardware standard replacing the PCMCIA/PC Card/CardBus cards, both developed by the Personal Computer Memory Card International Association. The host device supports PCI-Express and USB 2.0 connectivity in the ExpressCard slot, and each card uses the mode of connectivity the designer considers more appropriate for the task. The cards can connect to the computer on without RESETiarlo (support Hot swap or hot plug). It is an open standard of the ITU-T and its definition can be obtained from the official website of ExpressCard. You can connect to this bus, different types of peripherals such as Wi-Fi cards, Bluetooth, TV cards, FireWire, etc.

Universal mobile telecommunications system (Universal Mobile Telecommunications System or UMTS) is one of the technologies used by mobile third-generation successor to GSM, because the GSM technology itself could not follow an evolutionary path to get to providing services considered third generation. Although initially is designed for use in mobile phones, the UMTS network is not LIMITADaa these devices and it can be used by others. What are the differences between GSM and UMTS? The GSM system operates by TDMA, ie, time is divided into slots and each user is assigned a slot, ie, a period for which data can be transmitted. Therefore each channel is shared by a number of users. The system is a UMTS (WCDMA) code division multiple access dand broadband. In this system there are no time slots and GPRS. All users transmit simultaneously on the channel, but each user signals are encoded with a unique code so that even though we think that an "indecipherable signal" is formed by using the same frequencies simultaneously, It is not, because the base station is capable of decoding and re perfectly separate each of the communicationsreceived from different users. This obviously implies a much higher channel utilization, to not share in time.
