- 21. 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 with 6 km coverage radius deployed in 50 MHz of available spectrum: #3 #1 #4 #2 Copyright 2013 Cambium Networks, Inc.

- 27. Competitor’s MAC Protocols PD is incurred 3 times for each UL transmission (One for Poll and one for UL data and one for ACK) Transmit and receive one STA at a time Propagation delay is compensated for each transmission. ACK/NACKs and retries occurring per Tx & Rx What does this mean? • Individual Tx/Rx, Propagation delay all adds up to less time for actual data transmission. • With increased #of subscribers, latency starts going up drastically and significantly reducing TCP tput • Interference in one SM could engage CCA, retries and increase latency for overall sector
- 28. ePMP MAC Protocol Efficiency • Efficient Use of RF Capacity – tight packing of data and reduction in overhead of propagation delays • Allows for High SM Scalability • Allows for Consistent Performance even in High Interference Environments 28 Single Message Polls and Schedules Multiple SMs on Uplink Data from Multiple SMs is “tightly packed” Due to use of Uplink Transmit Timing Advance DL UL Copyright 2015 Cambium Networks, Ltd.

- 46. VOIP on ePMP Copyright 2013 Cambium Networks, Inc. All Rights Reserved. 46 ePMP utilizes the following mechanisms for best in class VOIP delivery • Packet loss and latency has been optimized for VoIP packets • DL/UL automatic prioritization of VOIP packets within the queues of the radio. • High priority/ more frequent bandwidth allocation to SMs carrying VOIP traffic • SMs with VoIP Packets to send will “piggyback” a bandwidth request onto uplink data transfer STA can send VOIP packet but also request BW for the next voip packet by piggy backing. This allows AP to schedule the STA sooner
