This is a great question.  We have mentioned “dual band amplifiers” in the past.  When we talk about dual band we are generally referring to an amplifier.  This means the amplifier is built to amplify/enhance signals for both the 800 MHz cellular or the 1900 MHz PCS frequencies.

Bandwidth has several related meanings, for our purposes in the wireless industry there are two primary definitions:

Bandwidth (computer)digital bandwidth: a rate of data transfer, throughput or bit rate, measured in bits per second (bps).

Bandwidth (signal processing) or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz.

Bandwidth is a measure of available or consumed data communication resources.  As technology grows and our desire for seamless connectivity grows, bandwidth use increases as well.

RF Engineering, also known as Radio Frequency Engineering, is a subset of electrical engineering. It applies to devices which are designed to operate in the Radio Frequency spectrum. RF Engineering is incorporated into almost everything that transmits or receives a radio wave which includes, but not limited to, Cell Phones, Wi-Fi and Public Safety Solutions.

RF Engineers are a part of a high;y specialized field and are an integral part of in-building wireless solutions. Their expertise is needed to design effective and reliable solutions. To produce quality results, an in-depth knowledge of mathematics, physics and general electronics theory is required. Even with this, the initial design of an RF Circuit usually bears very little resemblance to the final physical circuit produced, as revisions to the design are often required to achieve intended results.

RF Engineers are specialists in their respective field and assist in both the design, and maintenance of our solutions. Often, creative and collaborative solutions are required in the wireless industry, we work closely with our RF engineers to deliver quality solutions. The range of technologies used is vast due to the wide array of frequencies allocated for different radio services, and due to the range in age of equipment.

Each frequency range has a band designator and each range of frequencies behaves differently and performs different functions. The frequency spectrum is shared by civil, government, and military users of all nations according to International Telecommunications Union (ITU) radio regulations.

For communications purposes, the usable frequency spectrum now extends from about 3Hz to about 300GHz. There are also some experiments at about 100THz where research on laser communications is taking place but we won’t discuss this now. This range from 3Hz to 300GHz has been split into regions.
