FAQ


What is EBlink’s core technology?

EBlink’s patented wireless fronthaul technology provides a wireless connection between the base station baseband unit processing element (BBU) and the Remote Radio Heads (RRH/RRU).

It offers a practical and economical alternative to the optical fiber generally used to connect the BBU and RRH. EBlink’s wireless fronthaul products digitally interface the BBU and RRH/RRU using the CPRI protocol, enabling interoperability with a wide range of base station and radio providers.

They offer greater deployment flexibility, better site integration and cost savings to mobile operators.

What is a remote radio head (RRH)?

Modern base stations consist of two parts, the Base Band Unit (BBU) and Remote Radio Heads (RRH/RRU). They are usually connected by optical fiber and communicate via industry-standard interfaces such as CPRI, OBSAI or ORI.

Most mobile operators deploy remote radio heads close to the antenna in order to benefit from higher radio performance.

What is fronthaul?

Fronthaul is the link between a base station’s or NodeB’s Base Band Unit (BBU) and Remote Radio Heads (RRH/RRU). It is distinct from backhaul, where the link is between the baseband unit and the core network.

EBlink’s FrontLinkTM system preserves downlink and uplink radio performance and achieves radio KPIs comparable to those obtained with an optical fiber connection.

It allows up to three independent channels on a single wireless fronthaul link supporting 3-sector site configurations or tri-band remote sectors, i.e a total of 7.5 Gb/s CPRI signal, carried over less than 70MHz.

EBlink’s FrontLinkTM system uses patented technology, and is the first and most advanced commercial wireless fronthaul solution available in the market.

What are the benefits of EBlink’s wireless fronthaul solutions?

EBlink’s wireless fronthaul products allow carriers to expand network capacity and coverage without introducing complex new network layers.

EBlink’s products can be used to deploy or expand traditional macro cellular sites, or to deploy micro or pico cell sites using smaller, cost-effective transceivers.

EBlink also offers a convenient, low-risk and flexible solution for future distributed RAN architectures such as Cloud RAN or local Cloud RAN. Traditional small cell architectures introduce a new network layer and added complexity.

With EBlink’s wireless fronthaul solution, operators can deploy RRH/RRU within the existing macro network. Centralized baseband processing enables better coordination, interference minimization and homogeneous network management.

Where can EBlink’s solutions be installed?

EBlink’s solutions are applicable to virtually any installation, including macro sites and cell towers, light poles, water towers, rooftops, pylons and masts, right of way sites, Cell on Wheels (CoWs) and temporary installations.

Our system requires no cable trays, and can be fitted to an existing installation or to free-standing composite-base structures.

What are the economic benefits of EBlink’s solution vs. a fiber installation?

The cost savings provided by EBlink’s solutions vary from one site to another, and are directly related to site complexity; the more complex the site, the greater the savings.

Fiber installation often poses new challenges and requires expensive construction, particularly in more densely-populated areas.

Compared to cable, EBlink’s products allow for faster site deployment, drastically cutting time to market for the network operator. At every stage, from planning through negotiation, installation and construction, EBlink’s solutions save time and cut costs that are often hidden or underestimated.

They also meet the requirements of landlords and local authorities in terms of urban integration.

Industry studies have concluded that wireless fronthaul represents a 40% average savings versus fiber-based deployment.

Do EBlink’s systems support multi-sector site configuration?

Yes, EBlink’s FrontLinkTM 58 product can support up to three sectors on a single link, making it suitable for single-sector, bi-sector and tri-sector sites.

Are EBlink’s products compliant with government regulations ?

Yes, our products meet CE and FCC standards.

What do industry experts have to say about EBlink’s wireless fronthaul technology?

  • Alain Maloberti, Chief Network Officer of Orange, welcomes the agreement between Alcatel-Lucent and EBlink. He mentions:
    “Orange has been working with EBlink for several years and we are pleased with the performance of their wireless fronthaul solutions. We fully support the integration of EBlink’s technology into the roadmap of our base station vendors”.
  • “Our work with EBlink allows us to further extend this comprehensive portfolio to meet all of our customers’ LTE and small cell deployment needs”.
    Philippe Keryer, Chief Strategy and Innovation Officer of Alcatel-Lucent.
  • “EBlink wireless fronthaul solution provides significant TCO advantage for remote RRH deployment, paving the way for new network architectures.”
    Denis Fauconnier – 4G PRODUCT Management Director of Alcatel-Lucent.
  • “In just a few months, EBlink has demonstrated that it can attain the ambitious performance levels predicted. It’s remarkable”, comments Jean-Luc Vuillemin, director of the Orange France network. “From Orange’s point of view, it’s important that the OEMs participate in the integration of this new technology. For our part, we have created a team that is working with EBlink to study all the possibilities this technology holds for the Orange network”.
  • “EBlink FrontLinkTM solutions have the potential to change the way mobile network operators deploy their networks in the near future. EBlink has proven that a distributed Radio Access Network approach was now feasible using wireless CPRI transport without sacrificing network performance”
    Stephen Bye – CTO Senior VP Technology Development & Strategy.
  • “We have been using EBlink’s products on our network in France since 2009 with full satisfaction on the performances and reliability of EBlink’s products. Wireless fronthaul is important to consider for Orange France and I see a good potential for FrontLinkTM, because of the immediate answer to our needs in the race of deployment for capacity” commented Sylvie Lienard, Director of Radio Engineering at Orange France.
  • “EBlink’s wireless fronthaul stands out in terms of product performance, with ground breaking spectral efficiency. FrontLinkTM, the company wireless fronthaul solution, is a compact all-in-one outdoor solution which enables mobile operators to smoothly expand their network coverage and capacity. In terms of QoS, FrontLinkTM performs just as well as fiber, acting like a “wireless fiber”. The solution is field proven and has demonstrated radio KPIs similar to fiber installation. EBlink technology combines the benefits of fronthaul and the flexibility of wireless. It is a key enabler for Centralized RAN and Local Centralized RAN.”
