Exalt Portfolio All Configurations, All Bands EX-i Series (all-indoor) ExtremeAir, ExploreAir ExtendAir, EX-r(rc) Series (all-outdoor), EX-s Series (split-mount) Licensed: 6L, 6U, 11 GHz LE/LL: 2.4, 4.9, 5 GHz 11, 13, 15, 18, 23, 28 GHz 4.5, 4.9, 5, 24 GHz 6 40 GHz Full-duplex L2: 15 250 Mbps 15 1000 Mbps 50 360 Mbps page 6

Types of Radio Frequency Spectrum License-exempt Anyone can use No coordination or registration required Opportunity for interference, which the user must work around Licensed (or Leased ) Coordination required Registration required Interference is better controlled Lightly Licensed Like licensed but reserved for government use Simplified licensing process and coordination requirements Owned Purchased spectrum, usually in a given region, usually by auction page 7

Understanding Your Backhaul Costs Radio cost System Gain Antenna costs Leasing of tower space Installation costs Sparing and logistic costs Licenses, if required Power consumption Environmental (ex: cooling the inside of a cabinet?) page 8

System Gain: Why is it important? The system gain of your radios can have a direct effect on: How far can the path reach Path reliability Examples: 99.999% = 5.26 minutes/year outage ( five nines ) 99.995% = 26.28 minutes/year outage 99.950% = 262.8 minutes/year outage page 9

System Gain: Why is it important? The system gain of your radios can have a direct effect on overall cost: Antenna size: every 3 db difference in system gain is one antenna size difference The larger the antenna the more expensive the antenna It s more expensive to install larger antennas Wind and weight loading on the towers Real estate and zoning restrictions Cost of leasing antenna space on towers is usually by linear ft., so larger antennas cost more per month page 10

Exalt Differentiator Simplified and Reduced Cost of Sparing (All-outdoor) Fieldreplaceable diplexer All-outdoor ExtendAir and ExploreAir Radio is band-specific Field-replaceable diplexer defines sub-band Enables a single SKU spare for each band End User stocks one spare configured radio End User stocks inexpensive spare diplexers in multiple sub-bands as desired Sparing costs drop by up to 90% compared to competing all-outdoor and split-mount systems page 11

ExaltSync and ExaltSync GPS TDD radios (ExaltSync) All-outdoor TDD radios (GPS) ExaltSync enables six radio systems (Frequency A) to be collocated on the same tower, using either internal or GPS synchronization A single GPS unit can provide timing for multiple Exalt radios (EX-5r GigE shown) page 18 ExaltSync reduces required physical separation between antennas

Ethernet Rate Limiting WITHOUT Ethernet rate limiting or 3x10/100 BaseT LAN Subscriber Traffic Management & Surveillance Traffic Total available throughput is used on a first-come, first-served basis, regardless of traffic type WITH Ethernet rate limiting and 3x10/100 BaseT No rate limit Rate limit: 20 Mbps LAN Subscriber Traffic LAN Management & Surveillance Traffic page 19 Apply rate limit of 20 Mbps to port associated w/ mgmt. Balance of max throughput is always available to subscribers.

CarrierTDD Throughput Symmetry Control TDD radios Example: EX-5r GigE 440 Mbps maximum aggregate throughput, 50/50 default configuration Peak 286 Mbps in one direction at 65/35 asymmetric split Peak 352 Mbps in one direction at 80/20 asymmetric split page 20
