Analog vs. digital cellular phones

Cellular phones are an amazing modern convenience, but it can be confusing for consumers to distinguish between the various options available. There are two main types of cellular phones: analog and digital. Each type operates slightly differently and has its own unique advantages and disadvantages.

The first cellular phones were analog phones. Analog phones are basically an extremely sophisticated radio and telephone combination. The main advantage of analog cellular phones is that they cost less than the newer digital phones. Analog phones are also a better choice for travelers, since 95 percent of the county is equipped for their use. The drawbacks of choosing an analog phone are the reduced sound quality and the slightly higher per minute rate.

Digital cellular phones use the same basic technology as an analog phone. The difference is that digital phones use binary code and compression to fit more calls into a given bandwidth. Digital cellular phones offer longer battery life, better signals, and cheaper calling rates. The main disadvantage of digital cellular phones is that many parts of the country aren�t equipped with the proper antennae to receive digital signals. This makes digital cellular phones inappropriate for frequent travelers or individuals who live in rural areas.

Sprint often uses the term PCS in their promotional materials. PCS stands for Personal Communications Service and is a wireless communications service very similar to cellular phone services. Many people use the term PCS as a synonym for a digital cellular phone, but a true PCS phone offers additional services such as caller ID, paging, and e-mail as part of its regular phone service.

Newer cellular phone models may offer a dual mode feature. This option allows you to automatically switch between analog and digital modes depending upon what antennae are in your range. Dual mode phones combine the advantages of both analog and digital cellular phones.

Hydrogen Powered Cell Phone Battery - A Reality

Written by H2 Daily Staff

Sunday, 17 February 2008

Offering twice the run-time of batteries and with recharge times on the order of 10 minutes, Angstrom's EverOn capability promises to supplant the lithium ion batteries commonly used in today's portable electronic devices. Angstrom has announced a global first with the completion of a six-month test of fully integrated fuel cell-powered mobile devices. This revolutionary power platform was successfully integrated into MOTOSLVR L7 handsets for the trial, with no modification to the outside dimensions of the devices. The trial devices did not rely on the use of any battery - instead, they drew power from Angstrom's Micro Hydrogen platform, which is comprised of a novel fuel cell architecture, innovative micro-fluidics and a revolutionary refillable hydrogen storage tank. Angstrom has demonstrated research results showing twice the talk-time of the equivalent batterypowered devices in side-by-side testing. Angstrom is currently collaborating with world-leading battery manufacturers, portable electronic device makers and mobile service providers towards the commercialization of its Micro Hydrogen technology. "As consumer demand for smartphones and multimedia devices grows, so does the need for efficient powering solutions that help enable 'always on' experiences." said Jerry Hallmark, Manager, Energy System Technologies, Motorola Mobile Devices business. "Motorola is working with Angstrom to develop fuel cell technology that will support the increasing energy demands of next generation devices." The commercialization of Angstrom's technology reached another milestone on November 16th, 2007, when the International Civil Aviation Organization (ICAO) created new regulations that will permit Angstrom Power's devices to be transported globally in the passenger cabin of commercial aircraft. Final approval is expected before the regulations take effect in January 2009. With approval from Transport Canada, which preceded the ICAO regulations, Angstrom products have already made more than 60 commercial flights to date. Stuart Robinson, Director of Handset Component Technologies at Strategy Analytics Ltd, commented, "Our research shows that insufficient battery run time ranks as one of the leading considerations in the adoption of handheld devices with rich multimedia functionality. Development of Lithium batteries is too slow to meet the growing energy demands of cellular handsets. Angstrom's achievement, the world's first successful integration of micro fuel cell technology into a standard mobile handset, demonstrates the potential of micro fuel cells to provide a better solution for demanding mobile energy applications." The addressable market for Angstrom's technology is estimated to exceed a billion units annually by 2010. cell phone
