When installing a cell phone signal booster system, antenna separation is important because when the tower (outside) antenna and device (inside) antenna are located too close together they will pick up each other’s signals and create a feedback loop – a condition called oscillation.

You’re already familiar with the negative effects of oscillation. That ear-splitting screech that results when a public address system microphone is placed too close to a speaker is a consequence of oscillation.

If a signal booster system oscillates you won’t hear any noise, but the equivalent of that PA system screech will be picked up by all nearby devices on the cellular network.

How to overcome oscillations?

Oscillation interferes with cell signal transmission and reception, and if left uncorrected it can damage the cellular network. For this reason, the FCC requires all signal boosters to auto-detect oscillation. When oscillation is detected, FCC regulations require that the signal booster immediately take corrective action.
When a booster detects oscillation it will automatically power down its gain, or signal boosting power, in an attempt to correct the oscillation condition. This gain reduction will reduce the booster’s indoor signal coverage area. Moreover, if reduced gain does not correct the oscillation condition then the booster, by FCC regulation, must shut itself off. All this happens within a few hundredths of a second.

Obviously we want to avoid oscillation-caused gain reduction and booster shutdown. These can be prevented by locating the tower and device antennas far enough apart from each other. We refer to this as the Minimum Required Separation Distance, or MRSD.

The horizontal separation distance required to reach MRSD is greater than the vertical separation needed to get MRSD. Using a combination of vertical and horizontal separation to achieve MRSD is perfectly acceptable. Also, facing the tower and device antennas 180 degrees away from each other will help you reduce MRSD. And a roof or wall between the two antennas may also help you reduce MRSD.

Radio Frequency Systems (RFS), a global wireless and broadcast infrastructure specialist, has enhanced its portfolio of passive RF components with an entire suite of new products – 90 in all – to provide a full range of solutions for all wireless in-building commercial and mission-critical communications requirements. New products complement RFS’ comprehensive line of low loss RF feeder cables and jumpersfor DAS and include passive DAS components such as couplers, power splitters, tappers and hybrid combiners.
RFS’ comprehensive, passive DAS product portfolio enables RF wideband, multi-band, multi-technology, and multi-operator support. It provides the ability for future systemic shifts between operators or frequency bands to support any changes in macro network providers and/or technologies, including re-banding/re-farming of spectrum. All RFS components deliver high-quality and highly reliable in-building wireless systems for both commercial and mission-critical applications. RF cables combine flexibility and strength with low attenuation and high power ratings; non-cable components maintain overall system and PIM performance; and RF-over-fiber repeaters can be used to re-amplify signals across long distances.
Meeting the coverage and capacity demands of in-building wireless services, every passive DAS solution must be purpose-built for specific business objectives, application requirements, and physical environments. RFS, which had previously committed to providing professional services for these types of applications, now offers the expanded product portfolio to aid customers in deploying these future-proof solutions. Comprehensive RFS services and solutions ─ which are optimized for cost and performance ─ assist customers through the entirety of the design and deployment stages, with the added potential to provide a turnkey solution, if desired.
This DAS product line expansion enables RFS to better deliver all of the capabilities needed to give people greater access to wireless services indoors with maximum flexibility and optimum electrical performance. All frequency bands are now covered including mission-critical (380-520MHz), commercial wireless (698-2700MHz), broadband and ultra-broadband (380-2700MHz) in 2G, 3G, 4G LTE and TETRA. Mission-critical and commercial communications can be configured to function over one broadband network.
In addition to a broad offering of frequency bands, RFS’ hybrid combiners and hybrid couplers can combine multiple signals within the same wireless band in a common cable. Directional couplers (5 dB, 6 dB, 7 dB, 8 dB, 10 dB, 15 dB, 20 dB and 30 dB) uniformly distribute RF signals for unequal splitting to compensate for cable loss at higher floors.
As required for all RFS products and systems, each of the updated passive components have undergone the same rigorous testing as all other RFS products, upholding the company’s high quality standards. RF distribution via coaxial cable such as RFS’ Cellflex cable offers loss reduction, and power splitters evenly split input signals with minimal reflections or loss. All RFS passive DAS products share harmonized PIM specifications (-150 dBc) to maintain this high level of repeatability and reliability of services.
All passive DAS components are now available worldwide as RFS looks forward to continuing to update and expand its product offerings in other lines to further ensure comprehensive coverage for all RF installations.

A brew of both good and not too good buzz from the customers is ringing at the manufacturer’s ears. Well, most of the reviews are really amazing, in fact genuine and authentic. One of the customers switched from a Verizon cell phone to the Iphone 4 and AT&T. Coverage in their area, Sedona, AZ was not that great with AT&T. He was getting 1-2 bars and a few dropped calls with his new phone. But amazingly, when I went up on the roof, he discovered 5 bars on his phone. The very excited customer bought the Wilson unit and installed it as per their clear instructions, http://seismic-shock.com/cell-phone-booster/a-walk-through-cell-phone-repeater-guide/ Electronics DT Cell Phone Signal Booster and the amplifier in my living room. It raised his bars in the house to 4-5 bars. Calls are clear and strong now. Most of the customers say if the signal is faint it will help a lot. Some only get 1x connection but without this they get almost no signal.
On the other hand, there are handful of customers who are really not happy with the product. They find the product to be worthless as they find no signal improvement in their area.
Nevertheless, huge numbers of customers simply love the product and find it to work the way they wanted and expected. Our excited customers are set to recommend this product to their friends and relatives.
I think one need not go sceptical reading about this product. The signal bars definitely shows a huge difference from no signal to 1 Bar to 3bars-4bars. And that’s a remarkable difference for many who used to literally miss their important calls and texts. In simple words, the manufacturers give the customers the guaranty that it works as it is been advertised.
