Mobile communications are merely a means. All that will do is give people traveling the same capabilities they have now when they're in your office. However, within 10 to 20 years, should make the working environment is more direct and seamless. The microphones, for example, collected voice wherever one is in the office, at home or in the car.

In short, a new word will enter the vocabulary of Spanish telecommunications, is the i-mode. In a turbulent time for European and world markets in general and for telecommunications in particular, dominated by the continued delay of the next generation of GSM (better known as UMTS) and instability seems to threaten to become chronic.

Suppose that is already in the summer of 2001. What is needed to access the UMTS system? Despite the system not yet be fully developed, it is possible to have an idea of the requirements needed to operate the new system:

It is the possibility of changing mobile operator company retaining the phone number that the user has before the change. If I change my mobile operator, I can keep the phone number. Some operators allow customers to keep phone numbers when switching service pattern, a contract prepaid card or vice versa. In this case we are not talking about portability. We refer to portability only when they change operator.

CDMA is a form of "the quilt - the spectrum," a family of digital communication techniques have been used in military applications for many years. The principle of spread spectrum center is the use of noise - the carrier waves, and, as the name implies, the bandwidth is wider than that required for simple point - to - point communication at the same rate of data.

It is the standard that defines a global wireless communication standard which enables voice and data between computers via a radio frequency link. The main objectives to be achieved with this standard are:

After the initial excitement that surrounded the WAP and the possibilities of the new system, the voices begin to emerge criticism. Jakob Nielsen, a renowned specialist in issues related to Internet and mobile telephony, describes this system in an opinion piece as being the "wrong approach to portability.

Mobile phones increasingly are becoming an indispensable tool for vacationers. It is not just to satisfy the desire to be communicable. Now with the new WAP services and positioning wins another useful instrument for travelers.

CDMA offers an answer to the problem of capacity. The key to its high capacity is the use of noise as a carrier wave, as first suggested decades ago by Claude Shannon. Instead of dividing the spectrum or disconnecting time "cracks" that each user is assigned a different case noise carrier. While these waveforms are not rigorously orthogonal if they are about.

The GSM has a number of features that differentiate it within the universe of mobile communications. Born in the 80 result of unprecedented cooperation in Europe, the systems share common elements with other technologies used in mobile telephony, as the digital transmission of voice and data and the use of cells. This article presents the basic technical characteristics of the system and its capabilities.

Recently we attended a GPRS expansion. The exchange of MMS and the possibility that they can be edited in our computer is one of the most spectacular applications of this technology. So far, the GPRS applications offered more field-focused professional to consumer.

The IS95 standard defined by the TIA (Telecommuniations Industry Association) of USA, and is compatible with the existing frequency plan in the United States for analog cellular phone. Specified bands are 824 MHz - 849 MHz for reverse-link and 869 MHz - 894 MHz for forward-link.

The implementation of GPRS technology will be developed in phases, because the technology has limitations and implementation of solutions for them. In the first phase will be used only to data, and then used to carry voice (never simultaneously with the data) and finally the joint transmission of voice and data.

UNIFICATION OF NAMES: For the purposes of these Regulations, the uniting of the names of Mobile Telephony Services (VTS), Cellular Mobile Radio (SRMC) and Personal Communications (PCS) in the "Service for Mobile Communications (MTS) .

When the operator receives a call, try to find the mobile phone to which it applies. Before roaming, the operator calls the phone via a massive signal to all cells in the region it operates, to find the phone and informs the mobile phone and base station cell frequency in which to operate.

I'll just talk about mobile Private Network, also known as radio communication in closed user group, is a mobile phone service that only lends itself to a group of people in a given geographical area, operation is identical to that of public networks , with minor nuances, there are two forms of service.

The services of mobile satellite communications have grown markedly in recent years, so it is estimated that nearly a thousand of orbiting satellites covering the globe in 2004.

Wi-Fi is similar to traditional Ethernet network and as such the establishment of communication needs to a previous configuration. It uses the same frequency spectrum as Bluetooth with a higher output power leads to stronger connections.

How to avoid that censorious gaze fixed intently when we we take the phone? The one wrinkle of the nose, or fans of the head, the words are so cold that just because we are talking about, so how to avoid all this? Are we doomed to look for all sides whenever we have to use it, as if we were committing a crime?

Sometimes I am amazed at the shortsightedness gets my point of view with some issues: Linux running inside an Applet For all (computers, and different ;-)) clearly understand the news, explained some technical data.
