DISTRIBUTED ANTENNA SYSTEMS
DAS
Components
DAS Headend
The headend converts the RF signal it receives from the base station and connects to the remote radio. The JMA DAS headend offers a flexible and modular solution that enables easy reconfiguration and future growth.
Features and Benefits
- Modular, easy-upgradable sub-racks
- Supports a mixture of low, medium, and high-power remotes on a single head-end
- Pay as you grow, no “rip & replace”
- Full continuous RF bandwidth support on all bands
- Flexible head-end can be powered by either AC or DC
- Embedded operations and management system, web-based graphical user interface
- Low latency and application support
- Supports all 3GPP technologies
Software Defined Radio Unit
JMA’s Software Defined Radio Unit (SDRU) provides a pay-as-you-go plan to add power and bands as needed through license keys.
Features and Benefits
- Enables pay-as-you-go; only pay for the bands and the power you need
- Most cost-effective hardware
- SDRU-based DAS solution offers flexibility in design without any fixed power limitations
- Allows DAS system commissioning for all bands with temporary licenses on day one
- No Truck roll – upgrade band or power remotely using a license key
- No need to add hardware, use more closet space, add cabling, compromise the remote, or introduce PIM
- The SDRU remains in place in an IP66/NEMA-4X sealed enclosure
- Upgrade is done in seconds and is not service-affecting enables revenue-generating operation in minutes
Public Safety DAS System
Public Safety DAS provides in-building emergency radio coverage to first responders. JMA Wireless offers a comprehensive solution for hosting first responder and public safety services on DAS.
Features and Benefits
- Solution supports a wide range of frequencies used in the public safety sector, 700 MHz, Band 14 (FirstNet), 800 MHz, and 900 MHz public safety bands
- Dual Band support
- Multiple power options available, which allows for scalability and adaptability to different deployment scenarios
- Industry's only integrated public safety / commercial co-siting solution. Ensuring both public safety and commercial bands’ protection from interference
- Each remote unit has an optional notch filter connection, enabling public safety co-siting and interference control.
- Compliant with regulatory and public safety authority's certification standards
- Future-proof solution, supports changes to P25 modulation (Phases 1, 2, or 3) and LTE modulation in the public safety frequencies without incurring additional costs
- DAS solution offers optimized near-far interference mitigation, providing consistent service across the coverage area
Dual-Band Remote Unit
The Dual-Band Remote Unit - a software-defined remote unit (SDRU) - supports both C-band and DoD band. Its C-band radio is unique in the market, covering the entire C-band spectrum (full 280MHz bandwidth).
Features and Benefits
- C-Band remotes offer operational bandwidth that covers the entire C-Band (3700 – 3980 MHz)
- Smallest 40W in the industry
- The C-Band remotes are 2x2 MIMO and can support 4X4 MIMO with 2xRU
- Lowest power consumption per watt in the market
- Most cost-effective hardware
- C-Band remotes have a low NF, Low EVM, and High PAPR
- IP 66 (with optional OPK)
- Support 5G NR
JMA Omni antennas
JMA innovative in-building antennas are low profile with high directive gain, delivering optimal SINR, improving network capacity, and reducing deployment cost.
Features and Benefits
- Higher directive gain into the rooms – decrease in the number of antennas
- Reduction in leakage of energy above and below the floors for enhanced sectorization
- Greater than 10dB increase in SINR compared to traditional inbuilding Omni’s
- Improve network capacity and reduce deployment cost with higher SINR
