Russia Requires WiFi Registration
While WiFi wasnít as broadly unlicensed in Russia as it is in most other industrialized nations, your can not find wifi antenna anywhere a state regulator exempted indoor use in certain bands from registration. The Mass Media agency apparently believes that it has the authority to compel this, although thereís some doubt by observers as to whether it really falls in their purview.

W-CDMA transmits on a pair of 5 MHz-wide radio channels, while CDMA2000 transmits on one or several pairs of 1.25 MHz radio channels. Though W-CDMA does use a direct sequence CDMA transmission technique like CDMA2000, W-CDMA is not simply a wideband version of CDMA2000. The W-CDMA system is a new design by NTT DoCoMo, and it differs in many aspects from CDMA2000. From an engineering point of view, W-CDMA provides a different balance of costs vs. capacity vs. performance vs. density, and promises to achieve a benefit of reduced cost for video phone handsets. W-CDMA may also be better suited for deployment in the very dense cities of Europe and Asia. However, hurdles remain, and cross-licencing of patents between Qualcomm and W-CDMA vendors has not eliminated possible patent issues due to the features of W-CDMA which remain covered by Qualcomm patents.

How Does Satellite TV Work?

Broadcast stations use a powerful antenna to transmit radio waves to the surrounding area. Viewers can receive the signal with a smaller antenna. The radio signals used to broadcast television emit signals from the broadcast antenna in a straight line. To receive these signals, the satellite dish has to be in the direct line of sight of the antenna. Obstacles like trees or buildings are not a problem, but a big obstacle, such as the Earth, will reflect radio waves.

What Are The Types of Satellite TV Distribution?

There are two primary types of satellite television distribution: Direct Broadcast Satellite (DBS) and Television Receive-Only (TVRO)

Direct broadcast satellite (DBS) also known as "direct to home," is a relatively recent development in the world of television distribution. Direct broadcast satellite can either refer to the communications satellites themselves that deliver DBS service or the actual television service. DBS systems are commonly referred to as "minidish" systems. DBS uses the upper portion of the KU-band.

DBS systems rely upon proprietary reception equipment, most often in the form of a television set-top signal descrambling box. This measure assures satellite television providers that only authorized, paying subscribers have access to the content.

The first commercial DBS service, Sky Television, was launched in 1989 and served customers in the United Kingdom. Hughes' Direct TV, the first high-powered DBS system, went online in 1994 and was the first North American DBS service. In 1996, Echostar's Dish Network went online in the United States and has gone on to similar success as Direct TV's primary competitor. Commercial DBS services are the primary competition to cable television service.

Television receive-only, or TVRO, refers to satellite television reception equipment that is based primarily on open standards equipment. This contrasts sharply with direct broadcast satellite, which is a completely closed system that uses proprietary reception equipment. TVRO is often referred to as "big dish" satellite television.

TVRO systems are designed to receive analog satellite signals from both C-band and KU-band satellite television or audio signals. TVRO systems tend to use larger rather than smaller satellite dish antennas, since it is more likely that the owner of a TVRO system would have a C-band-only setup rather than a KU-band-only setup. Additional receiver boxes allow for different types of digital satellite signal reception, such as DVB/MPEG-2 and 4DTV.

What Is The Advantage of Satellite TV?

The advantage of satellite TV over cable TV is that it offers you even more choices...up to 300 channels! With satellite TV, you can pick which company you want to subscribe with and what package of channels to buy. This is different from cable television, where you are forced to purchase whatever system your region offers and pay whatever price it offers. Direct TV and Dish Network offer you this advantage and more!

W-CDMA has been developed into a complete set of specifications, a detailed protocol that defines how a mobile phone communicates with the tower, how signals are modulated, how datagrams are structured, and system interfaces are specified allowing free competition on technology elements.

We ensure high quality WCDMA Antenna products by subjecting our WCDMA Antenna products to stringent quality control measures during each stage of production and while dispatch.
