As a key contributor to the wireless densification evolution, SOLiD Distributed Antenna Systems (DAS) empower cellular coverage and capacity at hospitals; sports and entertainment venues; government, university and corporate buildings and campuses; international airports and metropolitan subways; and other high-profile sites.

SOLiD is also advancing the densification revolution through Cloud RAN and next-generation indoor / outdoor solutions that reimagine the wireless network. SOLiD has helped SK Telecom deploy one of the world’s first and largest Cloud RAN networks with our optical fronthaul technology.

From LTE and FirstNet-ready solutions to a portfolio that’s tailored for virtually any project; pre- and post-deployment ingenuity that reduces complexity and risk… SOLiD delivers the advantage to ensure wireless service any time, any place

ALLIANCE Multi-Carrier DAS

SOLiD's high-power output requires less hardware and, therefore, costs less than comparable systems, while delivering superior performance. Our solutions support all public safety and cellular services from 150/450 radio to 2.5TDD, with just one strand of fiber to each remote.

Their unique modular design lets you buy what you need now, and then cost-effectively expand and upgrade your network in the future.

The value continues with features like their rugged, yet compact, remote units that comply with the NFPA and IFC fire codes and NEMA 4 requirements, at no additional cost. Plus, SOLiD's solutions feature the most precise filtering available in DAS systems on the market. This eliminates interference issues and permits simple load balancing among all your cellular services. Combine that with the most up-to-date system management and control software available on the market today, and it becomes clear why SOLiD is considered one of the leading RF systems manufacturers in the world.

EXPRESS Single-Carrier DAS

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.

EXPRESS is both flexible and sophisticated to support SISO as well as MIMO configurations. EXPRESS makes efficient use of building fiber – typically using just one fiber to connect a building. And like the ALLIANCE DAS system, SOLiD’s multi-carrier DAS solution, EXPRESS is durable so it can be mounted indoors or outdoors. Plus its small footprint design requires minimal space.

By greatly improving in-building RF coverage, the EXPRESS system allows service providers and enterprise locations to deliver high-quality mobile voice and data services at any site in a building or campus environment. The system can be used to cover both public institutions and private facilities, including:

  • Shopping malls
  • Hotels
  • Corporate and university campus areas
  • Airports
  • Clinics
  • Subways
  • Multi-use stadiums and convention centers
The Express DAS platform serves two primary market segments: first as a carrier deployed coverage enhancement product for their specific frequencies and second as a low cost, public safety / single carrier product.

DMS DAS Management Systems

The DMS-1200 gathers vital system information and alarm data from the DAS network and transmits via SNMP to the designated NOC facility for monitoring.

The DMS-1200 keeps downtime to a minimum and ensures your SOLiD system remains reliable. Comprehensive DAS system health checks are continually conducted and changes in status and alarm detection are reported in real-time.

Whether you monitor with your own network computer, or utilize a sophisticated carrier-grade NOC, the DMS-1200 is the interface that will perform to the highest of standards in any application.

SOLiD Management Software
In addition to the DASTrax DMS, SOLiD's management and configuration software may be used to view and adjust critical device settings either remotely or on the local network.

Optical Fronthaul/Backhaul

SOLiD is an innovator in DWDM (Dense Wavelength Division Multiplexing) which channelizes a single fiber strand into multiple bi-directional channels. With a single strand from the hub site, SOLiD transports the signaling and transmission over a distance span and facilitates linear add/drops from the single fiber to Small Cell site locations. The linear add/drop simultaneously handles both backhaul and fronthaul. Infinity Access, SOLiD's optical transport solution, reduces sparing costs by up to 95%, offers centralized provisioning and enables network commissioning within hours versus days.

A single fiber ring simulataneously supports 2G/3G, 4G and WiFi traffic: CPRI/OBSAI is used to support LTE traffic, Ethernet supports WiFi, and E1/T1 is used for the legacy 2G/3G network.

SOLiD's digital network solutions deliver zero jitter and packet loss and ultra-low latency, are capable of carrying GbE, SONET up to an OC-48, EPON, GPON or CPRI up to 3.07Gbps, and flexibile to support multiple topologies including point-to-point, tree-and-branch, chain, and ring. Furthermore, the architecture is inherently optimized for VoLTE and upcoming LTE-Advanced capabilities.
