Some countries, provinces and states are considering banning hand mobile phone use whilst driving or require that a "hands-free" system be used. Many european countries and New York already require a "hands-free" device for mobile phone use in vehicles, and other. States and municipalities are following suit. As technology progresses and data demands have increased on the mobile network, the latest in scares is the 3G higher bandwidth towers. The network has sparked many health concerns and community outrage. Examples of such can be seen from headlines around the world; locals in the uk pulling down 3G masts, authorities in Denmark lobbying against the government's rollout of 3g networks to stop until a dispute is made, australia - sydney leichhardt protests banners were demonstrated. The spurt of protest appears to be the common reason for human fear, the unknown. There have been very little communications between governments and communities providing information about the introduction of 3G upgrades.

A third standard, iden, is found exclusively in North America and is confined to use by the nextel network. It's believed that this network will eventually disappear as Nextel merges with Sprint pcs, a cdma carrier. Similarly, at t wireless's tdma network in North America is slowly being phased out as a result of its merger with Cingular, a gsm carrier. Main article: Mobile phone radiation and health. As with many new technologies, concerns have arisen about the effects on health from using a mobile telephone. There is little scientific evidence for an increase in certain types of rare tumors in long-time, heavy users. More recently a pan-European study provided significant evidence of dna damage under certain conditions. So far, however, the world health Organization Task force on emf effects on health has no definitive conclusion on the veracity of these allegations. (see also Electromagnetic radiation hazard). It is generally thought, however, that rf is incapable of producing any more than heating effects, as it is considered non-ionizing radiation, in other words that it lacks the energy to disrupt molecular bonds such as occurs in genetic mutations. Another controversial but perhaps more lethal health concern is the correlation with automobile accidents.

Probably more importantly, the wcdma air margaret interface has been designed with gsm compatibility in mind. It has a special mode of operation, known as punctured mode, in which, instead of transmitting continuously, the mobile is able to stop sending for a short period and try searching for gsm carriers in the area. This mode allows for safe inter-frequency handovers with channel measurements which can only be approximated using "pilot signals" in other cdma based systems. A final interesting case is that of mobiles covering the ds-wcdma and mc-cdma 3g variants of the cdma-2000 protocol. Initially, the chip rate of these phones was incompatible. As part of the negotiations related to patents, it was agreed to use compatible chip rates. This should mean that, despite the fact that the air and system interfaces are quite different, even on a philosophical level, much of the hardware for each system inside a phone should be common with differences being mostly confined to software. As can be deduced from the above, most mobile phone networks now use one of two standards, gsm or cdma.

Beyond that, though, statement there are challenges at each level of integration. How difficult these challenges are depends on the differences between systems. The different variants of the gsm system have only different frequencies and so aren't even considered true multi-mode phones but rather are called multi-band phones. When talking about is-95/gsm multi-mode phones, for example, or amps/IS-95 phones, the base band processing is very different from system to system. This leads to real difficulties in component integration and so to larger phones. An interesting special case of multi-mode phones is the wcdma/gsm phone. The radio interfaces are very different from each other, but mobile to core network messaging has strong similarities, meaning that software sharing is quite easy.

Dual, tri or quad band) mobile phone is a phone which is designed to work on more than one gsm radio frequency. The multi-mode case occurs mostly in gsm which originated in the 900 mhz band, but expanded to other bands including 18Mhz bands. Some multi-mode phones can operate on analog networks as well (for example, dual band, tri-mode: amps 800 / cdma 800 / cdma 1900). Multi mode phones have been valuable to enable roaming but are now becoming most important in allowing the introduction of wcdma without customers having to give up the wide coverage of gsm. Almost every single true 3G phone sold is actually a wcdma/gsm dual-mode mobile. This is also true.75G phones such as those based on cdma-2000 or edge. The special challenge involved in producing a multi-mode mobile is in finding ways to share the components between the different standards. Obviously, the phone keypad and display should be shared, otherwise it would be hard to treat as one phone.

For this reason, saudi Arabia has entirely banned the sale of camera phones (although the country allows pilgrims on the hajj to bring in camera phones south Korea has ordered manufacturers to ensure that great all new handsets emit a beep whenever a picture is taken. Gps receivers are starting to appear integrated or connected (i.e. Using bluetooth) to cell phones, primarily to aid in dispatching emergency responders and road tow truck services. Newer models have included many features aimed toward personalisation, such as user defined and downloadable ring tones and logos, and interchangeable covers, which have helped in the uptake by the teenage market. Usually one can choose between a ring tone, a vibrating alert, or a combination of both. Multi-mode plan mobile phones, a multi-mode (a.k.a.

In most of Europe, wealthier parts of Asia, and Australasia, mobile phones are now virtually universal, with the majority (in some countries and age groups up to 100 percent) of the adult, teenage, and even child population owning one. They are less common in the United States — while widely used, market penetration is lower than elsewhere in the developed world (around 66 percent of the. Population as of 2003). Reasons advanced for this include incomplete coverage, a mixture of incompatible technical standards (many european nations and some Asian nations force the gsm standard by law on all phones, while in other Asian nations the cdma standard is enforced; in the United States and Canada.

Worldwide deployment, mobile phones have a long and varied history that stretches back to the 1950s, with hand-held devices being available since 1983. Due to their low establishment costs and rapid deployment, mobile phone networks have since spread rapidly throughout the world, outstripping the growth of fixed telephony. Such networks can often be economic, even with a small customer base, as mobile network costs are mostly call volume related, while fixed-line telephony has a much higher subscriber related cost component.
