London Stock Exchange Group Page 8
Typical usage models used within our facility:
• Clients operating decision making systems within our co-lo - quick decisions using lowest
latency market data feeds for passive and aggressive market strategies
• Clients deploying strategies that seek opportunities between markets – using our central
location to gain good average latency benefits between other venues
• Clients including Exchange Data in mesh or backbone connectivity – bringing own fibres
into the Exchange Hosting facility
Exchange Hosting – growing financial community/hub in London:
• Broad mix of Proprietary Firms (Members and Non-Members), Prime Brokers, Service
Providers and Vendors
• Prime Brokers and Non-Members
 Well established financial services community served by numerous brokers
 Prime Brokers provide space within their racks for their clients, via cross connects within
the Co-lo space or routed from outside our facility
 Growing community of users able to connect to one another via short cross connects

9. Exchange Wireless
London Stock Exchange Group Page 9
Provides millimetre wave wireless connectivity between LSE City of London datacentre and
the Equinix data centre in Slough, significantly reducing latency between these key locations.
• Optimised path with the network deviating only 3% from the geodesic straight line between the
locations enabling data transmission to be up to 40% quicker than traditional low latency fibre routes.
• Network offering a shared bandwidth service with a total capacity of 1Gb delivered through the use of
millimetre wave technology – more bandwidth available for trading clients enabling greater flexibility and
transmission of data (including raw market data sets).
• Service utilises numerous repeater stations between the two end locations, with an average distance
between each repeater of less than 3 miles. Anticipated that clients will retain fibre connectivity for
resiliency.
• Signal strengths improved by installing additional links and reducing the distance between each
repeater, to reduce the impact of rain.
