What kinds of phones are the subject of this update?

The term “wireless phone” refers here to hand-held wireless phones with built-in antennas, often called “cell,” “mobile,” or “PCS” phones. These types of wireless phones can expose the user to measurable radio frequency energy (RF) because of the short distance between the phone and the user’s head. These RF exposures are limited by Federal Communications Commission safety guidelines that were developed with the advice of FDA and other federal health and safety agencies. When the phone is located at greater distances from the user, the exposure to RF is drastically lower because a person's RF exposure decreases rapidly with increasing distance from the source. The so-called "cordless phones," which have a base unit connected to the telephone wiring in a house, typically operate at far lower power levels, and thus produce RF exposures well within the FCC's compliance limits.

What are the results of the research done already?

The research done thus far has produced conflicting results,and many studies have suffered from flaws in their research methods. Animal experiments investigating the effects of radio frequency energy (RF) exposures characteristic of wireless phones have yielded conflicting results that often cannot be repeated in other laboratories.A few animal studies,however,have suggested that low levels of RF could accelerate the development of cancer in laboratory animals. However, many of the studies that showed increased tumor development used animals that had been genetically engineered or treated with cancer-causing chemicals so as to be pre-disposed to develop cancer in the absence of RF exposure. Other studies exposed the animals to RF for up to 22 hours per day.These conditions are not similar to the conditions under which people use wireless phones, so we don’t know with certainty what the results of such studies mean for human health.

Three large epidemiology studies have been published since December 2000.Between them,the studies investigated any possible association between the use of wireless phones and primary brain cancer,glioma, meningioma, or acoustic neuroma, tumors of the brain or salivary gland, leukemia, or other cancers. None of the studies demonstrated the existence of any harmful health effects from wireless phone RF exposures.

However, none of the studies can answer questions about long-term exposures,since the average period of phone use in these studies was around three years.

PPC 6600 specifications

The Audiovox PPC 6600 is a notable smartphone that emerged in the early 2000s, distinguished for its unique blend of features, technologies, and usability. Targeted towards tech enthusiasts and business professionals, this device was one of the early contenders in the smartphone market, showcasing Qualcomm's technology and Microsoft’s Windows Mobile operating system.

At the heart of the PPC 6600 is the Windows Mobile 2003 operating system, which provided users with a familiar interface, allowing them to access various applications and functionalities. Its integration of Microsoft Office Mobile allowed users to view and edit Word and Excel documents on the go, making it a practical choice for professionals who needed mobility without sacrificing productivity.

The PPC 6600 is powered by a 400 MHz Qualcomm MSM5200 processor, which was quite competitive for its time, enabling smooth multitasking and efficient application performance. It boasts 64 MB of RAM and 128 MB of ROM, offering adequate storage for essential applications and user data. Additionally, the device supports expansion via SD cards, allowing for additional memory, which is essential for users handling larger files.

One of the standout features of the PPC 6600 is its 3.5-inch touchscreen display with a resolution of 240 x 320 pixels. This display was characterized by the ability to handle both stylus input and finger gestures, giving users flexibility in navigation and interaction. The device also featured a unique slide-out keyboard, bridging the gap between touchscreen input and traditional typing, which appealed to users who favored tactile feedback.

Connectivity options on the PPC 6600 were versatile for its time, including Bluetooth, infrared, and a mini USB port, enabling users to connect to various peripherals and networks. The device also featured support for 802.11b Wi-Fi, allowing for fast internet access, which was a significant advantage in enhancing productivity on the move.

The PPC 6600 came equipped with a 1.3-megapixel camera, which, while basic by today's standards, provided users with the capability to capture memories and important documents. The device was powered by a removable lithium-ion battery, which offered reasonable battery life for daily tasks, although heavy users often needed to recharge more frequently.

In summary, the Audiovox PPC 6600 was a pioneering smartphone that successfully combined essential features, smart design, and early smartphone technology to cater to a growing audience of mobile professionals and tech-savvy users. With its comprehensive capabilities, it laid the groundwork for future smartphones, influencing the design and functionality of many devices that followed.
