Hardware Architecture

2.1

Power Supply

 

The W2x terminals can be powered from:

AC Mains via an external AC/DC power adapter (10-28 VDC)

Battery backup (Ericsson W25).

2.1.1Power Adapter

The provided power adapter has the following characteristics:

Input: 100-240V AC, 50-60 Hz, 3 pole AC inlet connector (IEC 320 power inlet).

Output: 12 VDC.

Power consumption: 7.0 W (typical) and 11.4 W (maximum) for Ericsson W20/21 and 9.0 W (typical) and 16.2 W (maximum) for Ericsson W25.

National power plugs are available for EU, UK, US and AU.

2.1.2Battery Backup (W25 only)

The Ericsson W25 can be fitted with a rechargeable battery to provide redundancy in case of an AC Mains power failure. The battery is available as an accessory and is facilitated within the unit. Additionally there is an internal battery charger that can recharge the battery.

2.2

UMTS/GSM Radio Interfaces

 

The W2x terminals support UMTS and GSM/GPRS/EDGE radio interfaces

 

where UMTS is the primary interface.

2.2.1

UMTS

 

The W2x terminals support UMTS 850/1900 MHz and 2100 MHz frequency

 

bands.

 

The UMTS interface supports the following characteristics:

 

• WCDMA

 

• HSDPA Category 11 and 12 (W20)

 

• HSDPA Category 1-6 and 11 (W21/W25)

 

The Ericsson W21/W25 is software upgradeable to 7.2 Mbps which means

 

support for HSDPA Category 7 and 8.

2.2.2

GPRS/EDGE

 

The W2x terminals support GSM/GPRS/EDGE 850/900/1800/1900 MHz

 

frequency bands.

W2x Series specifications

The Ericsson W2x Series is a robust line of advanced wireless communication solutions designed to meet the growing demands of both urban and rural environments. With a primary focus on enhancing mobile broadband experiences, the W2x Series represents a significant leap in technological capabilities, featuring both hardware and software innovations that drive connectivity forward.

One of the core features of the W2x Series is its support for next-generation mobile standards, including 5G New Radio (NR). This enables operators to deliver higher data speeds, reduced latency, and increased capacity to end-users. Leveraging Massive MIMO technology, the W2x Series utilizes multiple antennas at the base station, allowing for simultaneous connections and more efficient spectrum usage. This results in improved coverage and enhanced overall network performance.

The W2x Series also integrates advanced beamforming techniques. These techniques focus the signal in specific directions, which not only improves signal strength but also minimizes interference. This capability is particularly beneficial in dense urban environments where signal degradation can be a challenge.

In addition to its impressive 5G capabilities, the W2x Series is designed for seamless integration with existing 4G networks, ensuring operators can provide a smooth transition for users without significant disruption. This backward compatibility is crucial as it allows for a gradual rollout of new services while maintaining support for legacy devices.

Power efficiency has been a key consideration in the design of the W2x Series. The advanced hardware is engineered to consume less energy, thereby reducing operational costs and contributing to sustainability goals. Additionally, the series supports Intelligent Energy Management features that optimize power consumption based on real-time usage patterns.

Another distinguishing characteristic of the W2x Series is its modular architecture. This flexibility allows network operators to customize their deployments according to specific regional needs and operational requirements. Whether installed in remote locations or urban centers, the W2x Series can adapt to various physical and environmental constraints.

Security is also paramount in today's connected world. The W2x Series incorporates robust security frameworks that safeguard user data and ensure compliance with international standards. This focus on security fosters trust among users as well as network operators.

In summary, the Ericsson W2x Series stands out with its cutting-edge features, including 5G NR support, Massive MIMO, beamforming technology, and modular design. Combined with energy efficiency and enhanced security, this series is well-equipped to support future wireless demands, making it a vital asset for network operators looking to enhance service offerings and user experiences.
