www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 What is fixed wireless broadband? • High speed broadband services utilizing radio waves instead of copper or fiber optic connections. • Not mobile or satellite • 2 major architectures types • Point-to-Multipoint (PTMP) • Point-to-Point (PTP) PTMP PTP
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Technological Improvements in Wireless • Movement towards standards based tech such as LTE and WiFi. • Lower prices, faster improvements • Not locked into one manufacturer • Interference Mitigation = Better Spectral Efficiency • Software • Beamforming • MIMO • Multiple In Multiple Out
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 What is 5G? • 5G is an evolution of the Radio Access Network (RAN) through the application of software and hardware developments to create the next generation fixed and mobile wireless network • Key performance targets: – High Speed - 20Gbps downlink / 10Gbps uplink – High Density - 1 million devices / km2 – Mobile – Energy Efficient – Low Latency - <1ms
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 What is 5G?
• Specified by the yet to be released ITU standard, IMT-2020 • We define 5G by a combination of: – Draft specifications – Use case scenarios driving innovation – Technologies behind the new networks • 5G networks will include: – Enhanced network architectures – New antenna capabilities – New licensed and unlicensed spectrums for 5G – Higher speeds and capacity – Low Latency • Release 15 RAN Approved 12/20/2017 • Release 16 due yet this summer
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Keys to a Successful Wireless Network
• Cell Density • Spectrum Selection • Spectral Efficiency • Backhaul

www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Selecting a Frequency Band • Decide if a licensed or unlicensed spectrum will be used. • Cost • Noise • Level of Service • Time to Deploy
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Selecting a Frequency Band • Unlicensed Bands Unlicensed Frequency Bands
o 900Mhz (low bandwidth availability has limited the use of this band)
o 2.4 Ghz
o 5.8 Ghz • Licensed Bands
o 2.5 Ghz
o 3.65 Ghz • Coming Soon
o 5G – millimeter wavelengths
o TV White Space
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 CBRS – Citizens Broadband Radio System • LTE Based • 3.55-3.70 Ghz, 150Mhz of new spectrum • Spectrum Allocation Service (SAS) will dictate spectrum usage for all • 3 levels of access – Incumbent – Military, Government, protected by Priority Access License (PAL) – Priority – Spectrum Blocks awarded by auction to highest bidder per census tract Hwang, Y (2017, June 9) What is CBRS? Retrieved from www.leverage.com – General – No license required, some regulation
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Ways to Deploy • Towers • Water Towers • Grain Elevators • Small Cells • Rooftops • Suburban
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Strategies • Acquire customers in unserved areas outside of existing service territory. • Increase revenue from existing assets. • Retain customers inside existing service territory. • Increase level of service, redundant feeds.

Propagation Preliminary Study Plan
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Challenges to implementing wireless networks • Line of sight or near line of sight required (LOS, NLOS). • Terrain/Topography • Interference Levels • Subscriber Density • Antenna locations, build v. lease? • Training • Reliability, has improved but not as good as fiber in most cases • Aesthetics
www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 What to expect • A fiber fed wireless network can be 3-5x cheaper than a fiber network in rural areas. • Speeds of 25Mbps and beyond can be achieved within a 6 mile radius. • Weather generally does not affect operation. • Equipment Lifespan 5-7 years • Backhaul Options • Fiber • Licensed Wireless • Unlicensed Wireless www.FinleyUSA.com Ben Humphrey,Chris Konechne Vice President [email protected]@fecinc.com @FinleyEng (507) 777-2255 Case Study Rural carrier has dark fiber at existing cell tower outside of their existing service territory. They want to acquire new customers that don’t have access to broadband speeds above 10/1Mbps.
• Lease space is available on the tower for $700/yr. • Low population density • 5Ghz unlicensed network • Terrain suitable for wireless network propagation study looks promising
