Frequently Asked Questions

Who are Avanti Communications and what do they do?

Avanti Communications is a satellite operating company providing wholesale services to Telecommunications companies throughout Europe, the Middle East and Africa.

Avanti connects people wherever they are – in their homes, businesses, in government and on mobiles. Through the HYLAS satellite fleet and partners in 118 countries, the network provides ubiquitous internet service to a quarter of the world’s population. Avanti delivers the level of quality and flexibility that the most demanding telecoms customers in the world seek. Avanti is the first mover in high throughput satellite data communications in EMEA. It has rights to orbital slots and Ka-band spectrum in perpetuity that covers an end market of over 1.7bn people. The Group has invested $1.2bn in a network that incorporates satellites, Gateway Earth Stations, datacentres and a fibre ring.  Avanti has a unique Cloud-based customer interface that is protected by patented technology.

What sectors does Avanti serve?

The flexibility and reliability of Avanti’s network enables Avanti to cover multiple sectors.

These core sectors are:

  • Mobile Operators
  • Internet Service Providers
  • Enterprise
  • Government Security/Defence and Civil

Avanti is also able to (and already does) provide capacity to other satellite operators.

What is Ka-band technology?

Ka-band (“kay-ay band”) is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range 26.5–40 gigahertz (GHz), i.e. wavelengths from slightly over one centimeter down to 7.5 millimeters. The band is called Ka, short for “K-above” because it is the upper part of the original NATO K band, which was split into three bands because of the presence of the atmospheric water vapor resonance peak at 22.24 GHz, (1.35 cm) which made the center unusable for long range transmission.

The 30/20 GHz band is used in communications satellites, uplink in either the 27.5 GHz and 31 GHz bands, and high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement. The Kepler Mission uses this frequency range to downlink the scientific data collected by the space telescope.

The designation “Ka-band” is from Kurz-above, which stems from the German word “kurz” meaning short.

In satellite communications, Ka-band allows higher bandwidth communication. Ka-band is more susceptible to rain attenuation than is Ku-band, which in turn is more susceptible than C band.

The frequency is commonly used by cosmic microwave background experiments.

The 5th generation mobile networks will also partially overlap with Ka-band (28, 38, and 60 GHz).

Why Ka-band technology?

Ka-band technology allows for smaller terminals, dramatically lower costs as well as offering greater throughput than similar sized Ku systems. This is perfectly suited for customers on the move (e.g. remote office, media broadcast or military), and in other applications where terminal size and weight are important factors in making purchasing decisions.

As Ka-band is at the top of the commercially available frequency range, it is somewhat more complex to provide high availability and reliable services as compared with lower frequencies. However, Avanti has an extremely well-developed and growing network of Ground stations which mitigates adverse weather conditions and ensures a 99.9% service uptime for customers.

For Military users, Ka has arguably the most benefits and offers notable efficiencies over Ku. For example, Ka-band is the only frequency where the commercial and military bands have been allocated adjacent to each other (29.0-30.0 GHz and 30.0-31.0 GHz respectively), and as a result, military end users can more easily complement their MilSatCom capacity with commercial bandwidth using a single terminal. Ka-band advocates say that this makes terminal development easier and more affordable, since a simplified terminal design can operate flexibly across a variety of commercial and military resources.

Can you describe the HTS market that Avanti operates in?

The market for High Throughput Services (HTS) Bandwidth in Avanti’s regions is valued at $542m in 2017 and is forecast to grow at 37% p.a. By 2022, the market value is expected to be around $2,642m (according to NSR Global GSCSD 14th Edition and Avanti’s analysis).

Global demand for satellite services is expected to grow by 33% over the next five years.

What is the Avanti advantage?

Avanti’s network was designed with reliability and flexibility at the core, meaning it can deliver higher quality services to a wider range of market sectors. The advantages are summarised below



  • Full Coverage
    Avanti has designed its fleet to offer 100% national coverage of primary countries. Our beam patterns overlap, so there are no in-country coverage gaps.
  • High Spectral Density
    Avanti’s network design means that Service Providers can use the smallest possible terminals providing a cheaper, attractive and more efficient way of delivering bandwidth to their customers.
  • Smart Beam Clusterin
    Avanti’s beam clusters land in a single earth station in the relevant country or region.  Service Providers who want a national service only need to operate through a single hub.
  • Diverse Networks
    Avanti’s ground network is protected from atmospheric events. In the unlikely event of service degradation, we automatically switch to our redundant ground earth station.  Customers experience no atmospheric outages at the gateway.



  • Multi-Vendor Platform
    Service Providers often have preferences for vendor hardware.  Avanti operates an open architecture enabling the use of any vendor’s hub or modem.
  • Contracting Flexibility
    Service Providers can choose from three methods of operation/contract to suit their own risk appetite, technical capability and which they can change between as the business evolves.
  • Operational Support System (OSS)
    Our proprietary OSS, backed up by high levels of training and support, allows Service Providers to configure and manage service as if they owned the satellite fleet.
  • Advanced Applications
    Service Providers have the flexibility to form their own applications from Avanti’s cloud or pick plug-and-play applications to deploy directly into their target markets.

How many satellites does Avanti operate and what are the capabilities of each satellite?

Avanti operates 4 satellites, HYLAS 1, HYLAS 2, HYLAS 2B (via ground operations from Germany) and HYLAS 4:

  • HYLAS 1 –  HYLAS 1 is Avanti’s first satellite, which launched in 2010. The satellite uses the latest Ka-band technology to deliver high speed, reliable and secure communications across the UK and Europe. HYLAS 1 has a unique and flexible payload which enables Avanti to change the bandwidth of its eight Ka-band beams whilst in orbit, maximising the satellite’s efficiency.
  • HYLAS 2 – Launched in 2012, HYLAS 2 uses high throughput Ka-band technology to deliver ultra-fast data communications. The spacecraft has 24 fixed beams and one steerable beam. HYLAS 2 provides customers with the flexibility to address current and future markets across Europe, the Middle East, the Caucasus and Africa.
  • HYLAS 2B – HYLAS 2B provides 100% Ka-band coverage of Germany and Poland, with extensive coverage of surrounding European countries and the Baltic Sea.
  • HYLAS 4 – HYLAS 4 launched in 2018 and doubles Avanti’s capacity. The spacecraft has 64 fixed beams serving 35 countries across Africa and Europe, as well as four independent steerable beams able to address markets across Africa, Europe and Latin America.

These satellites cover 27% of the World’s population; 65% of the World’s 20 fastest growing economies; 118 countries covered and a total Land Area of 139.072m SQ KM; a population of 5.3bn; a GDP of $62.419tn and a GNI of $65.933tn.

How much ground infrastructure does Avanti have and where are they placed globally?

Avanti has dual-redundant Gateway Earth Stations (GES) across Europe the Middle East and Africa to ensure no single points of failure and resulting in a claimed 99.9% uptime service level.

The company has GES in the following locations:

  • Goonhilly (UK)
  • Berlin and Hamelin (Germany)
  • Konya (Turkey)
  • Cyprus
  • Dakkar (Senegal) – currently being built
  • Lagos (Nigeria)
  • Johannesburg (South Africa)

Avanti has planned future dual-redundant GES in Kenya and Tanzania.

Avanti also operates Point of Presence (PoP) stations in London, Amsterdam, Frankfurt and Istanbul.
