1 Maximizing PMP network performance in high noise environments Jeremy Vincent epmp Channel Manager

2 Real World Performance in UL Spectrum Real world performance is effected by many factors Noise non specific RF radiadon Interference Other transmifers operadng at high power and/or in close proximity Equipment Ability to tolerate or overcome noise and interference while using available spectrum most efficiently Antennas gain, beamwidth, side lobes and front-to-back rado 2

3 Tools to overcome the impediments Unlicensed spectrum is congested! Technologies that increase interference tolerance to provide higher performance and consistent latency under external interference GPS SynchronizaNon provides a solid foundanon for your network s deployment and growth Rate adapt algorithms adjust radio operadon automadcally to boost performance and resilience Dynamic Filtering can help filter out interference from adjacent bands Beamforming/Beamsteering reduces the interference from muldple sources by using a narrow beam (vs wide sector beam) 3

4 How much beter is ac Advantages of ac More SpaDal (MIMO) Streams results in more throughput Wider Channels result in more throughput Higher ModulaDon results in higher throughput Wave 2 MU-MIMO Disadvantages of ac More SpaDal Streams requires higher SNR Wider channels receive more noise and more interference Higher ModulaDon requires very good SNR How does ac help in real outdoor condidons 4

5 Achievable MCS levels at different SNR Worst Real-word SNR Average Real-word SNR Best Real-word SNR 5 Table from wlanpros.com

6 How to improve SNR (higher SNR=more throughput) Increase Signal Higher Transmit power Higher Gain antennas How Higher the befer, but limited by FCC Both for SM and AP Lower Noise and Interference Narrow Channels How Use the narrowest channel possible Narrow Beam antennas Both for SM and AP (sector 90 vs 120) Beamforming (epmp 2000 and Medusa) Antennas with befer FB rado Synchronize co-located radios Receive Filtering Spend more money! GPS sync at the APs Use narrow/dynamic filtering (Hypure) efordfy 6

17 New 5 GHz epmp Sector Antenna (1000&2000) Frequency Reuse: Designed for ABAB channel re-use (two channels covering four sectors), the sector antenna has a 35 db front to back rado. Channel Flexibility: Consistent gain from 4.9 to 6.0 GHz. Consistent Coverage: Excellent null fill. Designed for the Installer: Small compact design, integrated epmp 1000 and 2000 radio mount and GPS antenna integradon. Predictable Performance: The sector antenna is integrated into Cambium Networks LINKPlanner. The 3D model shows coverage at all elevadons and across the azimuth.

Allow inter-operadon of 3rd party SMs to epmp access points. Create a network with virtual epmp SMs or a hybrid network and provide similar performance as a nadve all epmp HW network. MikroDk 22

23 Scope of epmp Elevate All licensing is managed at the AP (epmp2000 & epmp1000) Actual SM SW is free to download and installable to as many units AP controls how many non epmp devices are allowed connecdon to a pardcular AP This allows all control to remain within Cambium s secure licensing infrastructure Licensing at $35MSRP per non epmp SM connecdng to an epmp AP 23
