The great indoors
Solutions for in-building coverage have historically been addressed on a site-by-site basis. With high-speed data becoming more and more mobile, operators now need to improve the overall network capacity of indoor scenarios.
November 22, 2006
Mats Jensen, strategic product manager at Ericsson, says that until now, the main driver for indoor solutions has been site coverage. "That necessity is quickly being surpassed by a greater need for improved network capacity."
Today's indoor solutions no longer focus on providing coverage to an individual site but are more about off-loading the macro network and increasing existing capacity, specifically for data traffic. Demand also continues to increase for complex implementations with multiple sites - sometimes including hundreds of buildings.
Large multistory buildings, subways, tunnels and airports are a few scenarios where the implementation of indoor solutions requires a partner with integration experience and knowledge of the network at multiple levels.
Jan Söderblom, manager, In-Building Solutions, at Ericsson Global Services, says that being a prime integrator means acting as the sole interface to the customer. "There is a lot of coordination needed with suppliers, building owners, other equipment vendors and even with multiple mobile operators."
Many vendors of in-building equipment are often resellers with limited service offerings or network experience. Jensen says: "To do indoor coverage in a cost-effective and technically correct manner, you need to have overall understanding of the network." Experience in designing and managing complete networks is therefore a significant advantage.
Söderblom adds: "We are the largest telecom services company with 23,000 professionals and local presence in 140 countries. We offer local support with global expertise provided 24/7 - something our competitors in this area do not have."
For larger indoor projects there is a greater need for experienced personnel and project management. Ericsson has experience from thousands of in-building implementations including high-profile projects such as the Kuala Lumpur International Airport, the Taipei 101 Tower and the Suvarnabhumi Airport (the new Bangkok International Airport). Many large-scale projects include multi-technology, multi-operator implementations.
As the use of high speed mobile data services move increasingly indoors, the need for dedicated indoor mobile coverage will also increase. As mobile operators rapidly deploy High-Speed Packet Access (HSPA) they must also consider overall capacity improvements to manage this increase in traffic.
