  1. Connecting the Un-Connected and Under-Connected October 2013

  2. ePMP Genesis Cambium Heritage Cambium Innovation • Resiliency • Scalability • Performance • Security • Ease of deployment • Manageability • Mass Market 802.11n system on a chip (SoC) • Custom high performing, synchronized and scalable MAC and PHY • World’s most affordable, global broadband wireless solutionfor broadband wireless access to support developing communities, without sacrificing quality.

  3. ePMP Solution Overview A reliable, scalable solution at a breakthrough price: • 2x2 MIMO in 20 / 40 MHz channels • Incorporating key elements of Cambium’s scalable PMP Solutions • High Performance, Configurable GPS Synchronized operation • Effective QoS Management for support of prioritized data, voice and video • Designed for reliability following the Cambium Quality Process • Managed by Cambium Network Services Software solution • Available NOW, with enhancements to be introduced in the near future Cambium Unique

  4. The Power of GPS Synchronization

  5. Problems withUnsynchronized Wi Fi Solutions for Outdoor Broadband Wireless Access • Hidden Node Problem Causes “Collision Collapse” • AP to AP Interference when some APs Tx while others Rx • SM to SM Interference also can occur • One Solution: • No Freq Reuse • Large Guard Bands between frequencies Interference Interference Interference Customer Premises Customer Premises Customer Premises Customer Premises

  6. The Right Solution Is AHigh Performance GPS Sync Solution Key Components Benefits a) GPS Synchronized TDD MAC b) Automatic SM Tx Power Control c) Front-Back Antenna Isolation • Eliminates “Collision Collapse” and Primary Self Interference: • AP to AP Interference (DL to UL) • SM to SM Interference ( UL to DL) • Allows for Reduction in Guard Bands downlink uplink uplink downlink • Reduces Secondary Self Interference • SM to Other AP Interference (UL to UL) • AP to Other SM Interference (DL to DL) • Allows for Frequency Reuse 8

  7. Primary Self Interference AP6 AP1 Each AP is transmitting at a different time SM AP5 AP2 AP3 CMM AP4 AP1 AP2 AP3 AP4 AP5 AP6 AP: Access Point

  8. GPS Sync Eliminates PrimarySelf Interference AP6 AP1 Each AP is transmitting at the SAME time RM AP5 AP2 AP3 AP4 AP1 AP2 AP3 AP4 AP5 AP6 AP: Access Point

  9. SecondarySelf Interference - Uplink Auto SM TxPwr Control Auto SM TxPwr Control SM-X SM-Y AP-Y AP-X Freq A Freq A Antenna Back Attenuates Antenna Front Amplifies High Front Amplification and High Back Attenuation are required Need High Front to Back (F/B) Ratio > 30 dB

  11. The Importance of Spectral Efficiency • Spectral Efficiency: • A measure of how efficiently a wireless solution utilizes RF spectrum • Defined as Throughput Achieved (bps) per Spectrum Utilized (Hz) – bps / Hz • Clear Spectrum is a scarce resource • A solution that makes efficient use of this scarce resource provides a superior Return on Investment to the Network Operator • Example for Illustration: Four Sector AP Site #1 #2 #4 #3

  12. Spectral Efficiency of Deployment Alternatives • No Freq Reuse • Must have >= 2 x Channel BW Freq Separation between Chans • Spectral Efficiency is: • 4 x 80 mbps / (80 + 120) = 1.6 bps/Hz 3) A A A B B B C A C B D D • No Freq Reuse • Must have >= 1 x Channel BW Freq Separation between Chans • Throughput down to 50 Mbps • Spectral Efficiency is: • 4 x 50 mbps / (80 + 60) = 1.4 bps/Hz • 2 Channel Freq Reuse • Only 5 MHz Guard Bands between Adj Sectors • Throughput supports 80 Mbps • Spectral Efficiency is: • 4 x 80 mbps / (40 + 5) = 7.1 bps/Hz > 4X Spectral Efficiency 14 • No Synchronization • Incomplete GPS Sync: • Inefficient Sync’ed MAC • No TxPwr Control • Poor Antenna F-B isolation • ePMP GPS Sync

  13. The ROI of GPS Synchronization • 4X the Spectral Efficiency with ePMP, means • 4X the number of subscribers, which means • 4X the monthly revenue, which means • Much Faster Payback with the ePMP
