OneBase Pico Node B is a fully self-contained WCDMA Node B radio base station that supports 1700, 1900, or 2100 MHz bands. This single carrier picocell wireless base station provides 250 mW power output, features a capacity of up to 80 users, and at 6 kg (13 lb) in weight is easily deployed by a single technician.

OneBase® Macroshelf

The OneBase Macroshelf is a complete, open standard radio frequency solution that fits within the base station and integrates transceiver, power amplification, filtering, combining, and associated RF shelf hardware.

Based on CPRI™ and OBSAI open standards, the Macroshelf solution enables OEMs to cost effectively source the complete RF path from within the base station from one, trusted, single provider. Andrew’s design experience and greater economies of scale drive costs out of base station architectures and deliver OEMs the industry’s lowest cost solution for the entire RF shelf.

OneBase® MCPA Cell Extender

Multicarrier power amplifier (MCPA) Cell Extender extends coverage or increases capacity of wireless base stations by using a technology-agnostic design capable of simultaneously supporting any current wireless standard.

The MCPA Cell Extender is based on 135 W power amplifier modules that can provide signal amplification for mixed mode applications, such as CDMA, GSM/EDGE, and WCDMA. The unit can operate at 800, 1800, and 1900 MHz, has a dual band-capable sub-rack, and provides RF band filtering on the front end. Versions are offered for North American and European deployments.

The MCPA Cell Extender’s design takes into full consideration the operator’s needs, and its scalable, flexible platform consists of “standard” field replaceable units that are easily reconfigured for application-specific requirements. It comes in both indoor and outdoor versions.

Key benefits

• Economy by consolidating antenna feed lines
• Extension of cell capacity by supporting more channels without compromising coverage
• Seamless migration to future network evolution
• Extension of cell coverage
• Efficient spectrum usage
• Interleaving of hopping and fixing channels

Tower mounted amplifiers (TMAs) provide low noise amplification in the receive path (uplink) of the RF communications channel. TMAs have been deployed in networks for a number of years and provide better receive performance by balancing the RF power link budget. This improves coverage at cell margins and provides better communications quality for network users.

The OneBase Compact TMA combines small size and light weight with exceptional performance to address the challenges of site availability and network enhancements.

Key benefits:

• Smallest, lightest TMA in the market at 1.5 liter volume
• Low profile for simple visual integration on tower to meet restrictive zoning regulations
• Less weight and wind load on the tower - important when adding new services to existing towers
• Fully supports Antenna Standards Interface Group (AISG) standards for interoperability of antennas and control infrastructure
• Antenna line independent and backwards compatible with non-AISG UMTS sites
• Can be deployed with any electrical tilt antenna that complies with open industry standards

OneBase® Remote Radio Head

Fast Time to Market, Compact Size, Flexible Deployment

The remote radio head offers the ultimate in flexible deployment as part of a distributed base station solution. The compact size, high power, and low weight enable flexible deployment options, both tower top and at the base of the tower, for distributed base station architectures.

In the case where the remote radio head cannot be mounted close to the antenna, operation with a tower mounted amplifier (TMA) is also supported. Remote radio head product variants cover frequency bands from 700 MHz to 2.6 GHz and support the UMTS, CDMA, LTE and WiMAX standards.

The 60 W UMTS variant uses the latest Enhanced Class A/B amplifier architecture for improved efficiency and thermal performance.

Andrew Solutions Remote Radio Head products are customized to work with an OEM’s baseband processor and as such are not available off the shelf. Andrew has the ability to quickly adapt the interface software to a particular OEM’s baseband interface enabling quick time to market across multiple 2G, 3G, and 4G protocols and frequencies. See Product Specifications for a 2.1 GHz 60 W UMTS variant.

Operator customers need to procure these products from their base station vendors. They are not directly available from Andrew. Please contact your Andrew sales representative for more detailed information on how Andrew can make this product available.

Key benefits

• Free convection cooling—no fans
• Less than 15 kg installation weight
• 60 watts RF output power
• Width comparable to typical antenna housing
• Low cost
• 150 k hours mean time between failures (MTBF)
