Distributed Antenna Systems (DAS)

Providing good cellular signal coverage in buildings is a critical requirement. Construction materials - such as employed in 'green' LEED-certified buildings - are notorious for dramatically reducing signal reception for the occupants. In addition, most cities have now upgraded their building and fire codes to require good radio reception for fire, police and other first responders.

To alleviate these problems, builders and architects now make it a standard practice to install Distributed Antenna Systems (DAS) into construction projects.

The basic concept behind a DAS is the utilization of a bi-directional amplifier (BDA) that amplifies the outdoor signals and redistributes them inside the structure via a series of antennas throughout the building to bring good coverage to underserved areas. Typically, the outdoor signals will be received by an antenna on the roof which is connected to the BDA. The amplifier is bi-directional because it also needs to receive transmissions from cellular devices inside the building, amplify them and transmit them back to the local cell site towers maintained by the carriers (Verizon, AT&T, Sprint, etc.).

Wide Band Systems vs Narrow Band Systems

The most economical systems use wide band BDAs. This type of amplifier (FCC Class B) simultaneously amplifies the large blocks of frequencies utilized by all carriers for their services. Hence, one bi-directional amplifier will typically support AT&T, Verizon, T-Mobile and Sprint (US) or Bell, Rogers and Telus, etc (Canada). The problem with this approach is that if one of the carrier signals is much stronger than its competitors it will 'steal' a large percentage of the amplifier's power. This results in the redistributed signals inside the building being disproportionally allocated among the carriers. Therefore, the actual radio frequency (RF) signal environment outside of the building must be carefully analyzed before Class B amplifiers can be deployed.

Narrow band BDAs (FCC Class A) use filters to isolate the signals from each carrier. Typically a separate BDA is required for each carrier, and although the cost and hardware complexity is higher, the system will work efficiently in any RF environment. Unlike Class B broadband booster systems, Class A systems are configured with individual signal level adjustments for each carrier. For example, if the outdoor signal levels of Verizon are much stronger than AT&T, each can be individually amplified or reduced resulting in the same indoor strength for both carriers. This is much harder to achieve with the lower cost Class B broadband systems.

Fiber DAS vs Coax DAS

Classic systems use coaxial cables of various lengths and diameter to connect all of the amplifiers, antennas and signal splitters. However, long runs of coaxial cable can be expensive to install and can create many problems with signal losses if the cable run is over a few hundred feet.

For installations in larger buildings and campuses we frequently use fiber optic cables to interface between the remote bi-directional amplifiers which are distributed throughout the venue close to the indoor antennas they drive. This type of system is commonly referred to as 'Fiber DAS.' For example, the InLogis Model FOT-1 Fiber Optic Transceiver can transmit both the uplink and downlink RF signals on a single fiber strand. This technology enables installations impossible to implement with coax cable.
Public Safety Radio Enhancement Systems

First Responder Radio Coverage Requirements 

city-fire-codes

Most major cities within the United States and Canada demand strict adherence to a Fire Code that requires all construction over a certain square footage or height (varying from city to city) to support adequate radio coverage for First Responders. It is the responsibility of the building owner to determine the existence of good radio coverage, per code, and to correct any deficiencies.

Public Safety Radio Enhancement Systems ensure that First Responders are able to communicate effectively throughout any applicable structure. If a structure does not support adequate radio coverage (as determined by State, County or City regulations), the owner of the structure is required to install FCC-approved signal amplifiers, a distributed antenna system and backup power. Enforcement of the Fire Code is generally performed through the Building Permit / Certificate of Occupancy (CO) process.

Finding and deploying the requirements that a particular city demands is not a simple matter. Documents can be difficult to resource - and even harder to decipher. The National Fire Protection Association and the International Fire Code have established guidelines for State, County and City and these local regulations are subject to constant update. Example -  Clark County / Las Vegas Fire Code.

InLogis takes the guess work out of the process. We can identify the local requirements and integrate a Public Safety Radio Enhancement System meeting local codes.

Dedicated Broadband Cellular Booster Systems

How our Dedicated Broadband Cellular Booster Systems work

Our systems use outdoor antennas of varying gain and size which are selected as a function of distance from the tower and terrain blockage between the tower and the home or building. We have many different types of outdoor antennas of various sizes and shapes. The sizes range as small as 12 inches long that can barely be seen to as large as a typical satellite TV parabolic dish. Indoors, an amplifier boosts the cell tower signals and re-transmits them at a high level through antennas that are positioned to cover the entire space. The amplifier is bi-directional so when the cellular device is receiving or transmitting it amplifies the signals going to and from the tower. The indoor antennas (we have several different types) are very low profile and can be easily hidden in a closet, attic, cabinet or behind drywall. The systems are modular so we can custom design to accommodate any sized property with as many zones, amplifiers and antennas as necessary to provide good coverage.

InLogis dedicated broadband cellular booster systems can boost signals in all of the frequency bands in use in the US and Canada today and will work with all 3G and 4G LTE signals.

The amplifiers and antennas are wide band so they will simultaneously amplify all of the cell phone traffic from all the carriers that service a particular neighborhood. Your clients can use cellular devices supported by several different carriers all at the same time.
