EXPRESS Single Carrier DAS

SOLiD’s EXPRESS DAS is a single-carrier DAS solution engineered to meet the needs of wireless carriers across multiple frequency bands.

EXPRESS delivers agility and simplicity through SISO and MIMO configurations that are easy to design, commission and manage.

Rugged construction meets the latest fire codes and requirements for harsh environmental conditions.

* High efficiency with fewer components

* Rugged design and convection cooling means no moving parts

* 4G Certified, MIMO capable

* Typically one fiber needed to connect a building

* Small footprint, wall or rack mounted remotes

* Easy Setup – auto-configuration simplifies commissioning

* NFPA 72 Compliant / NEMA 4 Certified

The EXPRESS single-carrier Distributed Antenna System (DAS) efficiently delivers wireless signals into buildings, campus environments, or any locations that are difficult to cover with traditional outdoor macro networks. EXPRESS is designed for cost-effective deployment, rapid commissioning and simplified management of in-building wireless service to meet the needs of a single wireless provider across multiple frequency bands.

For the downlink path, the SOLiD EXPRESS Base Station Interface Unit (BIU) receives simplexed signals from the RF signal source. The input power range for the BIU is -20 dBm to +10 dBm. Variable attenuation is available up to 30 dB is available for both the TX and RX paths.

The BIU independently filters, attenuates and controls each signal and transmits these to the system’s Optical Distribution Units (ODU). The ODU converts the RF signals into optical signals and distributes them over fiber cabling to the EXPRESS Main Remote Units, or MRUs, in that sector.

The MRU converts the optical signals back to RF signals and transports them across coaxial cable to the DAS antennae which radiate the wireless signals within the corresponding sector to the user equipment. For the uplink, the signal follows the reverse path using the same equipment.

The MRU comes in both single band and dual-band configurations. Add-on Remote Units (ARUs) can also be connected to the MRUs to provide additional band coverage. In addition, a VHF/UHF Add on Remote (AOR) is available to support the 450MHz UHF and 150MHz VHF bands.

Each EXPRESS BIU consists of up to two MDBUs (SISO chassis) or up to two MDBUs (MIMO chassis) and can support up to nine or 17 discrete inputs per sector, respectively (four per MDBU and one V/UHF combined input on the BIU chassis). Supported bands include VHF, UHF, 700MHz, 800MHz, 850MHz, 900MHz, 1900MHz, 2100MHz, and 2500MHz TDD.

The DAS Management System (DMS-600) is a network management device that provides remote control and monitoring of the DAS through a standard Internet connection.
