Wireless Broadband Access (WBA) for Enterprise Customers

Why WBA for Enterprise Customers Enterprise Customers are demanding alternatives for Broadband Connectivity Need for increased Speed, Symmetrical needs, Price… Landline and Wireless SP have few cost effective options Nearly all Enterprise Customers can get WBA using Cambium Cambium PMP 450 can out propagate 3G/LTE signals from your towers Multiple tower sites makes nearly all Enterprise Customers accessible The most expensive part of deployment is obtaining Towers, Power and Backhaul (TPB) Wireless Service Providers have TPB in place today Cost of adding PMP 450 to a tower is quite small Why are Wireless SP not deploying Wireless Broadband today? Prior versions of PMP lacked key capabilities they demanded - high bandwidth, NLoS capability, licensed bands… Cambium has been successfully serving thousands of Enterprise customers in 140 countries using WBA for +10 years!

What WBA can deliver for Enterprise Customers Grow connectivity for existing Enterprise customers Provide 4G WBA service to your Enterprise customers without using 3G/4G spectrum Start as an alternative/redundant broadband access provider and then expand and grow Can replace expensive leased T1 access lines Opportunity to replace their expensive landlines VoIP service Opportunity to provide 3G/4G Offload at their facilities reducing the need to fortify or expand Network capacity Deliver symmetrical broadband to support Cloud Computing and video conferencing Provides bandwidth to support video surveillance Reach NEW Enterprise customers Provides a unique and differentiated ability to bundle 4G Broadband access with mobile offerings radically enhancing your ability to land new Enterprise Accounts See all of the bullets above!

WBA Beyond Enterprise Customers Backhaul your 3G/4G Off-load and Hot Spots Much more cost-effective way to backhaul traffic than using the Wireline Service Provider Expand BB service to existing and new residential customers Potential to offer 4G fixed broadband service at their residences as an alternative to xDSL or cable modem service Deliver any other services that are available to Enterprise customers Offer video services as well as voice and data Provide BB services to utilities, governments, or first responder customers Provide high-speed native IP links rapidly to collect nodal data, HD cameras… Deliver any services that are available to Enterprise customers

Example PMP450 Deployment for WBA 160 km2 coverage area 3/4G Sites: ~32 1:4 PMP450 Overlay: 8 Sites Total 8 site equipment cost ~ $53K USD Deliver 5 – 10 Mbps Business Broadband Service Packages for ~$100 USD/symmetrical megabit 2.2 Gbps Total Capacity in Coverage Area Capacity to serve ~500 Businesses Ability to reach nearly every EC 6 Month payback on total investment* (inclusive of RM, installation, tower space rental…) PMP450 3G/4G * Assumes adequate backhaul capacity exists

PMP 450 WBA Simple Economics PMP 450 Capabilities Throughput 90 Mbps per sector (ability to expand to 12 sectors per tower) Range 5 km radius – Further with antenna gain devices Remote Module 200 max/sector 2,400 max/tower Applications Cloud Computing, Streaming video, Voice, camera surveillance, other M2M applications AP ~$1.5k/Sector Remote Module ~$170 Add capacity based on demand Industries best nLOS capabilities Copyright 2012 Cambium Networks, Inc.
