Wireless services are provided subject to available bandwidth.
Exchange Wireless Service
LSEG's Exchange Wireless Service (EWS) provides ultra-low latency connectivity between key financial trading venues, enabling market participants to exchange order and market data between strategic locations with the lowest possible transmission delay.
The service utilises advanced millimetre-wave (MMW) wireless technology to create highly optimised network paths between LSEG's Exchange Hosting facility, Equinix LD4 in Slough and ICE's Basildon data centre. By following a near-straight-line route, Exchange Wireless delivers significantly lower latency than conventional fibre-based connectivity.
Available as either shared or dedicated bandwidth services, Exchange Wireless supports firms requiring the fastest possible access to trading venues and market infrastructure whilst maintaining enterprise-grade operational resilience.
What is millimetre-wave?
Millimetre-wave technology uses extremely high-frequency wireless radio links transmitted via a series of line-of-sight repeater locations positioned on dedicated towers and rooftops. Operating at substantially higher frequencies than traditional microwave networks, millimetre-wave technology enables higher throughput whilst delivering exceptionally low latency between connected sites.
Key features
- Ultra-low latency network paths engineered to minimise transmission delay between connected venues.
- Significantly faster data delivery than traditional low-latency fibre routes.
- Direct connectivity between LSEG Exchange Hosting, Equinix LD4 and ICE Basildon.
- Shared and dedicated bandwidth options available.
- Designed specifically for latency-sensitive trading and market data applications.
- Service continuously monitored and engineered to maximise availability and operational performance.
Fibre backup & data delivery service
To complement the primary wireless network, LSEG has introduced integrated Fibre Backup capabilities.
This optional service combines the latency advantages of Exchange Wireless with a dedicated lowest latency fibre path designed to support data delivery during periods when environmental conditions may impact wireless transmission. The solution provides customers with enhanced resilience whilst maintaining a highly optimised end-to-end network path.
Key benefits
- Enhanced service resilience through diverse transmission technologies.
- Improved certainty of data delivery for critical trading applications.
- Ability to maintain stateful TCP connections.
- Seamless integration with existing Exchange Wireless services.
- Suitable for latency-sensitive order entry and trading workflows.
- Optional dedicated service available alongside standard Exchange Wireless connectivity.
Capacity & availability
- Dedicated bandwidth options available from 100 Mbps to 1 Gbps and above, subject to customer requirements.
- Flexible service configurations to support a range of trading use cases.
- Fair bandwidth management policies ensure consistent service performance across subscribers.
- Capacity upgrades and service enhancements continue to be introduced in line with customer demand and market evolution.
Note: This infographic is provided in both visual and text formats so that all users can access the information in the way that suits them best.
The London Stock Exchange Group (LSEG) data centre is shown as the central location. To the west is Equinix LD4 in Slough, and to the east is the ICE data centre in Basildon. Direct wireless connections run between these locations, creating a low-latency communication network. The visual emphasis is on the near-straight-line routes used by the wireless service, illustrating the shortest and fastest practical path for data transmission.
The wireless links represent the Exchange Wireless Service, which uses millimetre-wave radio technology. Data is transmitted through directional line-of-sight radio signals that travel between communication points mounted on towers and suitable rooftop locations positioned along the route. The infographic visually contrasts this approach with traditional fibre-based connectivity by emphasising the more direct path taken by wireless transmission.
A key message highlighted in the infographic is that the wireless route provides lower latency than traditional fibre routes. The graphic indicates that data transmission can be up to 40% faster than conventional low-latency fibre connections linking Slough and Basildon with the LSEG data centre.
Supporting callouts around the network highlight the main service characteristics:
- Optimised network path with negligible deviation from a straight line between the connected data centres.
- Service engineered to maximise availability for wireless connectivity.
- Large bandwidth allocations available, starting from 100 Mbps and scaling higher as required.
- Dedicated bandwidth management helps ensure fair usage among subscribers.
The overall visual message is that the Exchange Wireless Service provides a secure, high-performance wireless connection between major market infrastructure locations. The infographic uses the direct wireless paths between London, Slough, and Basildon to demonstrate how millimetre-wave technology can reduce latency while maintaining high-capacity and resilient connectivity for market participants.
