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.

A Yagi antenna, also known as a Yagi-Uda array or simply aYagi, is a unidirectional antenna commonly used in communications when a frequency is above 10 MHz.  This type of antenna is low profile and ideal for cellular enhancement applications.

I simply had to post this picture……

We have had a crew out on multiple locations on the East Coast in the past few weeks.  I prefer to see completed installations in person but in some cases I rely on pictures from my lead technicians.  This one is a beauty; note the equipment rack and the amplifiers mounted on the wall in the background.  This is a really clean job and we have another happy client.  Thanks team!

It is important to be able to determine the cellular signal in and around your building for us to provide an accurate budgetary cost to you. Check out the information below that details how to put the various cellular phones in test mode. If you do not see your particular cellular phone on our list feel free to contact us directly.

In a telecommunications network the backhaul portion of the network comprises the intermediate links between the backbone, of the network and the small subnetworks at the “edge” of the entire hierarchical network.  An example would be: cell phones communicating with a single cell tower constitute a local subnetwork, the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the telecommunications network.

Visualizing the entire hierarchical network as a human skeleton, the core network would be the spine, the backhaul links would be the limbs, the edge networks would be the hands and feet, and the individual links within those edge networks would be the fingers and toes.

The objective in this type of solutions is to transmit data from several distribution/access points to one centralized point of presences.  This technology offers great benefit to enterprise, particularly campus style environments such as hospitals and universities.  Harris Communications offers both licensed and unlicensed point to point and multi point solutions.

Are dropped cellular phone calls leaving your tenants and residents frustrated?

If this is all too familiar for you and your tenants are not satisfied with the with the performance of wireless devices in the building, Harris Communications has solutions that will be of interest to you.   We offer single and multiple carrier designs that eliminate weak cellular signal and drastically improve cellular reception inside buildings.  Every solution is custom designed to ensure maximum performance at the best price point for our clients.

Our innovative wireless solutions eliminate dropped calls and ensure a seamless and productive workplace.   For more information please contact us directly so we can discuss your options.
