US Telecom Industry

The GSM (Global System for Mobile Communication) is originated from Europe and it was based on TDMA ( time division multiple access). The IS-95 was the CDMA (code division multiple access) technology. The CDMA System has a very large capacity and is somehow better than GSM. As the security of data is more in CDMA as compared to GSM.  But as we know, every technology comes with flaws, it can be minor or even major. So even 2G mobile communication systems also had some shortcomings, which were that 2G supports only voice services and low speed data services.
So to overcome these flaws, finally 3G came into picture. The main target of third generation mobile communication is to implement broadband multimedia communication and high- speed data services to subscribers. The main technologies of 3G are UMTS WCDMA, CDMA 2000. 3G was developed to achieve high spectral efficiency and high quality of service with complete security and reliability. 3G is named as IMT 2000. This technology is providing  remarkable  services to subscribers. But to satisfy the growing demands of users, now 4G is developed.
4G is named as LTE. The fourth generation cellular systems need to meet the requirements set out by ITU as a part of IMT Advanced. It has worldwide roaming capability. It provides extremely high data rate services.

  1. This is how my acquaintance Wesley Virgin's adventure starts in this SHOCKING and controversial video.

    As a matter of fact, Wesley was in the military-and soon after leaving-he revealed hidden, "self mind control" tactics that the government and others used to get everything they want.

    These are the exact same SECRETS tons of celebrities (notably those who "became famous out of nowhere") and top business people used to become wealthy and successful.

    You've heard that you use less than 10% of your brain.

    That's because the majority of your BRAINPOWER is UNCONSCIOUS.

    Maybe that expression has even occurred INSIDE your own head... as it did in my good friend Wesley Virgin's head seven years back, while riding an unregistered, beat-up garbage bucket of a car without a driver's license and with $3.20 on his banking card.

    "I'm very frustrated with living paycheck to paycheck! Why can't I become successful?"

    You took part in those thoughts, isn't it so?

    Your success story is going to happen. You just have to take a leap of faith in YOURSELF.
