Cellular Router Enables 3G - GPRS Connectivity To Industrial Equipment by Leon Mengot
Now, thanks to the Connectport WAN VPN, a next- generation cellular router designed to connect RS232 or Ethernet devices in-the-field directly to an internet facing PC, remote sites that previously could not connect to the internet can be networked and web connections made from mobile devices on... This can be especially useful when connecting to serial devices that intermittently output RS232 data. ... With support for GPRS, 3G and HSDPA the unit can provide connectivity via any network – simply put the appropriate SIM card into the unit, adjust two of the configuration settings and power...

SPI Bus: Theory and Implementation by O G Popa
SPI stands for “Serial to Peripheral Interface”, and it is a hardware and firmware communications protocol developed by Motorola and adopted by everybody. The SPI Bus is used only on the PCB. I am certain that some of you will ask: “Why is the SPI Bus used only on the PCB? ... Anyway, on the PCB the SPI Bus is very good, because we can practically attach to the Bus as many ICs (or devices) as we want. ... Things work like this: suppose that we have four devices, A, B, C, and D; all of them are wired to the SPI Bus lines, and the Bus itself is wired to seven controller pins--this is 3 Bus...

System Buses Explained by Alan Ogden
System Buses Explained I don't know about you, but I for one, despite thinking to myself that I had it all under my grasp always get confused when thinking about the array of buses in a modern computer. Bandwidth of the CPU, memory, AGP plus new technologies such as Hypertransport always leave... # Expand the bandwidth of the bus - Server motherboards, especially with the prevalence of SCSI hard drives requiring more bandwidth than the PCI bus can transfer, have moved to a 66MHz bus using 64bit slots.

New Laptop Technology You Need To Know (Before Buying Your Next Laptop) by Titus Hoskins
Laptop or notebook computer technology is advancing at a blistering speed. Ferrari fast. So fast that by the time you purchase your new laptop, it's probably already obsolete or out of date. A sobering thought considering the hefty prices you have to pay for a high-end laptop. ... Improved performance will be experienced because the new Pentium M's have a 533MHz frontside bus, supported with up to 2GB of DDR2 DRAM, Serial ATA Hard Drive, and PCI Express, plus improved integrated graphics, including Intel's Hi-Def Audio.

RFID: When You Don't Even Know It's There by Andy Reed
RFID (Radio Frequency ID) enables wireless data capture and transaction processing. Our last column discussed proximity applications, used primarily for access control. This time, we'll take a look at what are broadly defined as vicinity, or long-range applications, used for product tracking,... An RFID tag can be incorporated into each bicycle sold, and reputable pawn shops can be linked to a control system in the police department - or the police can carry a portable unit, similar to that used for writing parking tickets, to check merchandise and discover thefts.
