- 5. DAS Market in2000 • Only 38% of the US population used wireless • No “wireless-only” households • Primarily voice; Very little data traffic carried on wireless networks • In-building expectations low among commercial customers; even outdoor coverage was still patchy • Coverage was a “carrier problem” • No Enterprise budget for DAS • Carriers were the main purchasers of DAS systems • Enterprise customers accepted carrier terms in exchange for DAS 5
- 6. DAS Market in2013 • Wireless penetration exceeds 100% in US • Wireless services driven by data, multimedia and voice • Businesses running operations on smartphone, tablets and air-cards • Inbuilding coverage is now expected • Coverage becoming a “venue problem” • Tenants looking to building owner for coverage • Enterprises are budgeting for DAS • Increasing number of Enterprise customers for DAS • Carriers are more challenged selling single-carrier DAS 4G 6
