Wireless Broadband as a Last Mile Solution
Wireless Broadband as a Last Mile Solution Paul Budgen Canopy Wireless Industry Terms 1 Typical Solution Subscriber Module The Subscriber Module (SM) connects you to your Internet access network. 2 Canopy Backhaul Overview ine f ight ine f ight ear ine f ight on ine f ight Flat Plate or Dish !

Furthermore the trend towards agricultural tourism and for homes in un spoilt areas means this lack of service leaves large areas of the population without adequate communications. • Solution: VAPF construction has brought Canopy wireless broadband to its residents. The service is promoted as Voice over IP using the wireless Canopy internet connection. Residents also benefit from a 512Kbps broadband connection to the internet. • This has been achieved quickly and without the need for laying costly cables. Better still the network is completely scalable to meet the growing numbers of residents and saving the customer costly upfront investment in infrastructure. • Results: Everyone wins; residents have full internet and voice services which can be pre-paid and used on demand. • The urbanisation avoids a large upfront investment in costly cables and which take time to pay back. SMART Communications Philippines • SMART leading wireless operator with 20 Million cellular subscribers • They also operate a copper network around the country • Nationwide roll out of Broadband Internet and data services to residential & business subscribers using Motorola Canopy “We believe that wireless broadband is the most affordable way for the people in the Philippines to be able to receive reliable, high-speed Internet connectivity,” said Rene Dos Remedios, president of Meridian Telekoms, Inc, a subsidiary of SMART Communications 4 Cork Ireland Deploys Canopy Bringing High Speed Connectivity to Small & Medium Enterprises (SMEs) • Problem: Amocom Had Tried “Adapted” 802.11 Technology But Discovered That It Didn’t Scale Well & Proved Cumbersome To Rollout. Reliability Problems Resulted In Wasting Valuable Engineering Resources. • Solution: Amocom Chose Motorola’s Canopy Wireless Broadband Products, Based On The Fact That Canopy “Did What It Said On The Box,” • Result: Today Amocom Has Far Greater Coverage In The City & Surrounding Area Than ADSL & Serves The SME, Corporate, Educational & Residential Markets.
