Wi-Fi at Altitude: Ka-band, Low Earth Orbit and What Works

Wi-Fi on a business jet comes from one of four sources: towers on the ground, geostationary satellites on Ku-band, geostationary satellites on Ka-band, or the newer low earth orbit constellations. Which one is fitted decides whether you can join a video call, stream a presentation or only send messages, and on which parts of the route it works at all. The answer depends on the individual aircraft, so it is worth asking before you fly rather than after take-off.

Air to ground: towers below you

Air to ground systems use a network of ground stations that point their signal upwards, with small antennas under the aircraft. The equipment is compact and the delay is low, but the service only works over land where towers exist. For business jets this is essentially a North American option: Gogo operates networks across the continental United States and parts of Canada, and started the commercial rollout of its 5G air to ground network at the beginning of 2026. Over oceans, and in most of the world outside North America, business jets rely on satellites.

A cautionary note: a second US air to ground network, SmartSky, ceased operations in August 2024, leaving owners with installed hardware and no service. Provider stability is a fair question to ask.

Ku-band and Ka-band: geostationary satellites

Geostationary satellites sit about 35,786 km above the equator, so a request from the cabin and its reply travel up and down twice. Even at the speed of light that takes close to half a second, and more in practice. Browsing and email work well, video calls work with a noticeable lag, and some interactive applications and VPNs can struggle. Coverage is close to global, but it thins out towards the poles, where the satellites sit low on the horizon. The aircraft needs a steerable antenna, often in a fairing on top of the tail of larger jets.

• Ku-band is the older, widely used option, offered by several networks with broad coverage.
• Ka-band uses higher frequencies and concentrated spot beams to offer more capacity. Viasat, which now owns Inmarsat and its Global Xpress satellites, sells its business aviation Ka-band service as JetXP through partners including Collins Aerospace, Gogo and Honeywell.

Low earth orbit: lower delay, wider reach

Low earth orbit (LEO) constellations fly a few hundred to about 1,200 km up, so the signal path is far shorter and the delay is close to that of a good ground connection. That makes video calls, cloud applications and VPN work feel normal. Two LEO broadband networks now serve business jets:

• Starlink. Gulfstream holds FAA approval to install it on the G800, G700, G600, G500, G650, G650ER, G550 and GV, offers it on aircraft in production, and reported its 100th installation in September 2025. Approved installation kits also exist for the Bombardier Global family from the Global Express to the Global 7500.
• Eutelsat OneWeb. Sold to business aviation through Gogo's Galileo antennas. Textron Aviation announced the HDX version as a factory option on the Citation Latitude, Longitude and Ascend.

The antennas are flat, electronically steered units on top of the fuselage. Availability over some countries depends on national licensing, so check the route as well as the aircraft.

L-band: the quiet backup

Narrowband L-band services such as Inmarsat SwiftBroadband and Iridium Certus are slow by modern standards but very robust, and Iridium covers the poles. They carry cockpit data, voice and messaging, and on many jets they are the backup when the main system is unavailable.

Connectivity options at a glance

Technology	Where it works	Delay	Good for
Air to ground	Over land with towers, mainly North America	Low	Email, browsing, calls, depending on system
Ku-band (geostationary)	Near global, weaker towards the poles	About half a second or more	Email, browsing, streaming
Ka-band (geostationary)	Near global, weaker towards the poles	About half a second or more	Streaming, calls with some lag
Low earth orbit	Wide coverage including oceans, subject to licensing	Close to ground broadband	Video calls, VPN, cloud work
L-band	Global (Iridium including poles)	Variable	Messaging, voice, cockpit data

Speeds, costs and what to ask

Providers publish headline speeds, but the bandwidth is shared among everyone on board and, for satellites, among the aircraft in the same beam. Real performance depends on the antenna, the network load and the aircraft's position, so treat any single speed figure as a maximum. Costs are significant: as an indicative guide for autumn 2026, satellite hardware and installation commonly runs into six figures in US dollars, plus downtime, followed by a monthly service plan with a data allowance or an unlimited tier. On charter, Wi-Fi may be included, capped or billed separately.

Questions

Can I make video calls on a private jet?

Often, but it depends on the system fitted. Low earth orbit services handle video calls much like a ground connection, geostationary Ku-band and Ka-band systems work with a noticeable delay, and air to ground systems only work over land in North America. Ask the operator which system the aircraft has.

Does private jet Wi-Fi work over the Atlantic?

Satellite systems do, both geostationary and low earth orbit, although geostationary coverage weakens towards the poles. Air to ground systems do not work over oceans because they depend on towers on land.

Is Wi-Fi included in the price of a charter flight?

It varies. Some operators include it, some apply a data cap and some charge for use. Ask for the details in writing with your quote, including whether streaming and video calls are allowed.
