The Operation and Purpose of a Distribution Antenna System

 

The technology behind the distribution antenna system, or DAS, is far from new. In fact, it has been in use for more than two decades. However, in the face of an increasing demand from the continuing stream of ever-more capable, connected mobile devices, the need for a more cost-effective application of this technology has been driving developers to seek ways in which to employ fewer assets, yet achieve more from them.

Put an End to Dropped Calls with a Cell Extender

 

Given that mobile connected devices now outnumber humans on the planet by a substantial margin, our romance with the world of digital communications, and with the smartphone in particular, is well-established, On occasions, however, our affection for the latter can be severely strained and may become something of a love/hate relationship. While the high-definition digital camera may continue to function through thick and thin and never fail their owners when there is an opportunity for a selfie, the primary function of these devices can often be less reliable, calling for the help of a cell extender.

Poor Cellphone Signal? Get a Signal Booster for Indoor Coverage

 

Despite a succession of major improvements to South Africa’s cellular network coverage, the reality is that many subscribers still encounter difficulties with dropped calls and dead spots. When your need is purely social, although such problems may be a source of annoyance, they are hardly crucial. By contrast, in business a dropped call could result in serious consequences such as the loss of a prime client. Banking services depend on reliable connections as well. When such failures are persistent, for example, in one’s own home, the repeated need to walk out into the garden in order to make and receive calls or use data services can become extremely frustrating, irrespective of whether they may be social or business-related.

A Mobile Network Booster Could Solve Those Annoying Signal Issues for Good

 

While there can be no doubt that the area of South Africa within which effective cellular phone communication is possible has increased tremendously during the last decade or so, most users would agree that they still encounter areas in which the signal strength is consistently unreliable, or even non-existent. Whether in your own home, at a restaurant, in the office, or spending some time at the home of a friend, one will often find it necessary to move closer to the window or even to step outside into the garden to acquire a signal of sufficient strength to maintain a connection and so avoid dropped calls.

Signal Boosters Frequently Essential for Maximum Efficiency of Cellular Communications

 

After decades of enjoying the freedom to make and receive telephone calls whilst on the move, it is difficult to imagine how we might cope without our beloved mobile phones. What began as a relatively simple and somewhat bulky device with the ability to send and receive voice and text calls has since evolved beyond all recognition. Today, millions of people of all ages use their mobiles around the clock to post tweets, to update their Facebook statuses and to check out those of their friends. When not busy with their social media activities, many will be listening to music streamed by providers such as Spotify, watching movies from Netflix, or playing the slot machines at an online casino.

The Role of RF Communication Equipment in a Cellular World

 

Since the first, brick-sized cellphone made its appearance in 1973, consumers worldwide have been quick to embrace this new technology. In the ensuing decades, engineers have continued, not just to make these handy devices much more compact, but also to extend their use far beyond that of simply making and receiving voice calls. Today, it is claimed that mobile phones now outnumber human beings and there can be few pockets or handbags that don’t contain one. In addition to their original purpose, they are now able to transmit text and make video calls, to support multi-player gaming, to watch movies, to provide travel directions via the global positioning satellite network, and to support online banking and purchase transactions, to name just a few of the more common applications.

Why Cellphone Coverage is Poor in Places and How a Cellular Signal Booster Can Solve the Problem

Living in Africa, you are bound to have experienced some sort of cellular signal problem, such as dropped calls and an unreliable signal. Adding more towers to improve coverage will not adequately address the problem, because settlements with thousands of houses and buildings pop up overnight, causing endless headaches to radio planners. This is the main reason Africa is now also moving to 4G LTE on the newer frequency spectrum negotiated with ICASA. This could enable service providers to provide better coverage to subscribers from the same network infrastructure.

What is a so called “Signal Booster”?

A cell phone signal booster is a fully fledged cellular repeater, which receives the RSSI (received strength signal indication) from one or more BTS (base transmitting stations) outdoors and amplifies it indoors. It retransmits this amplified signal via an indoor antenna which radiates (makes available) this signal to a subscriber’s cell phone within this indoors area. This is called indoor coverage. The path the signal has travelled from the BTS to the cell phone is called the downlink or the MS (mobile station) path. This is the transmission that the subscriber hears. The opposite path where the subscriber talks are called the uplink or BTS path. This is when the cell phone signal indoors is amplified by the same repeater and is transmitted back to the BTS which connects the subscriber to the rest of the world.

Why am I not being told this when I order a repeater over the internet?

Poor cellular coverage has been a perturbing topic of discussion for some years now. All types of solutions to combat dead spots or poor signal quality have been implemented and the situation has not improved as expected. In urban areas, the use of cell extenders (repeaters or cell boosters) to address dead spots was expected to reach an overfill level, but the reverse is in actual fact being experienced, more and more dead spots are being created daily. This is partially due to the structures of the city skyline ever changing and cutting of the line of sight to base stations and very much due to the demand for broadband data frequencies which have difficulty penetrating concrete and brick buildings. The very high demand for 3G and 4G LTE is resulting in a race to plug holes before revenue escapes to the opposition or to other formats being offered.
