Mobile Phone Solutions

Starting a mobile phone or cell phone business can be a profitable business opportunity in a growing market. At the Consumer Electronics Show, Dr. Eli Harary stated “the mobile phone market is the mother of all growth markets.”

Mobile Phone Business Driven by Smartphones

Fueling the growth of the cell phone market is the evolution from standard cell phones to smartphones capable of more than a simple phone call.

Smartphones allow users to browser the Web, get GPS directions, listen to music, share photos and other forms of social networking, use email and run applications such as games and more.

Opening a retail cell phone store is one route to get into business. However, retail can be an expensive, competitive, low margin game. Alternative business opportunities exist for the mobile business.

The MultiMediaCard (MMC) is a flash memory memory card standard. Unveiled in 1997 by Siemens AG and SanDisk, it is based on Toshiba’s NAND-based flash memory, and is therefore much smaller than earlier systems based on Intel NOR-based memory such as CompactFlash. MMC is about the size of a postage stamp: 24 mm × 32 mm × 1.4 mm. MMC originally used a 1-bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time. It has been more or less superseded by Secure Digital cards (SD card), but still sees significant use because MMCs can be used in most devices that support SD cards.

Typically, an MMC is used as a storage medium for a portable device, in a form that can easily be removed for access by a PC. For example, a digital camera would use an MMC for storing image files. With an MMC reader (typically a small box that connects via USB or some other serial connection, although some can be found integrated into the computer itself), a user could copy the pictures taken with the digital camera off to his or her computer. Modern computers, both laptops and desktops, often have SD slots, which can additionally read MMCs if the operating system drivers support them.

MMCs are available in sizes up to and including 32 GB. They are used in almost every context in which memory cards are used, like cellular phones, digital audio players, digital cameras and PDAs. Since the introduction of Secure Digital card and SDIO (Secure Digital Input/Output) slot few companies build MMC slots into their devices (an exception is some mobile devices like the Nokia 9300 communicator, where the smaller size of the MMC is a benefit), but the slightly thinner, pin-compatible MMCs can be used in almost any device that supports SD cards if the software/firmware on the device supports them.
