Gigabit Fixed Wireless Solution juLY 2019

Networks comparison – Wireless Gigabit Networks The world is moving towards gigabit broadband with an immersive media consumption environment – requiring 5G based broadband & content delivery. Having access to infrastructure that can deliver such high speeds with integrated media delivery is crucial! AIR® system can deliver triple play services and speeds comparable to or even higher than newest wireline technologies for a fraction of the cost! AIR® FTTH Cable / DOCSIS 3.x 4G/5G > 1.000 Mbps > 1.000 Mbps > 1.000 Mbps 50 – 1.000 Mbps 2

LTE DOCSIS AIR® system capacity AIR® is a patented wireless technology for ultra-high speed broadband data transfer over great distances with the throughput and performance equaling that of the HFC (hybrid fiber coaxial) network. AIR® is the first wireless system that provides the same capabilities and speeds as new coaxial cable networks or enables delivery of triple play services with agreggation of multiple LTE carriers. LTE LTE modulation 256 QAM Maximum BS downlink throughput at 900 MHz per sector: 18 144 Mbps Maximum throughput at end user - 75 MHz Carrier Aggregation: 378 Mbps Modulation and throughput depend on eNodeB type and LTE CPE equipment DOCSIS Docsis 3.1 modulation 4 096 QAM Maximum BS downlink throughput at 1 000 MHz per sector: 41 378 Mbps Maximum throughput at end user - 192 MHz: 2 002 Mbps Modulation and throughput depend on Docsis CMTS type and Docsis CPE equipment

AIR® – No need to lay cables for a Fiber Like Service AIR® Last Mile is a wireless infrastructure that can completely replace any wired connection. Quick rollout No trenching No construction work Pay as you grow Fast ROI With the AIR® technology traditional non-incumbents can have cost effective access to high speed broadband without large scale investments. 4

AIR® as a backhaul to Wi-Fi, LTE or HFC AIR® last mile solution AIR® uses patented wireless technology to deliver ultra-fast broadband data over high frequencies by using higher order modulation techniques which require line of sight. AIR Base Station 2 – 42 GHz - FDD AIR® as a backhaul to Wi-Fi, LTE or HFC LoS AIR Transceiver nLoS nLoS up to 50 km HFC Hybrid Fiber Coax Network A very small percentage of non-line of sight situations can be overcome with proper base station location planning and complementary methods of broadband delivery. So no one is left in the dark.

Fiber Like Services Low Cost Quick Roll-out AIR® – Perfect last mile solution Fiber Like Services Up to 41 Gbps transfer rate per base station enables problem-free reception of multiple 4k HD TV channels and a broadband speed of up to 2 Gbps to the end user. Unique design enables support for triple play services (4kHD TV, VOIP, broadband). Low Cost Air® offers approximately 90% lower cost compared to deployment of wireline network. Low costs for set up, implementation and maintenance. One base station can serve up to 50.000 users, limited by total throughput. Customer indoor equipment is standard equipment offered by many vendors. Quick Roll-out AIR® Last mile solution can be operational in much shorter time compared to wireline deployments. No costly and time consuming road and construction work is needed to lay the cables in the ground, nor building permits. 6

Long Reach All Areas Quick ROI AIR® – Perfect last mile solution Long Reach AIR® system can serve customers located up to 50 km from the base station. Line of sight enables use of newest high level modulation techniques which are a guarantee for exceptional service quality and user experience. The system can be deployed in any frequency range from 2 to 42 GHz. All Areas Unique combination of long reach and high capacity makes Air system a perfect choice for all types of settlements. AIR® system can be equally effectively deployed in urban, suburban and/or rural areas. Quick ROI Low deployment costs, easy integration and low OPEX enable operators quick Return On Investment (ROI) usually less than 3 years. AIR® system offers a very good opportunity for investors and green field operators, especially in underserved areas. Enables „pay as you grow“ financing policy. 7

AIR® System Globtel’s technology AIR® consists of 2 main components: the base station and the transceiver combining proprietary components with standard Docsis, DVB/IPTV and LTE equipment. AIR® Base station Outdoor Customer premises AIR® Transceiver Outdoor Indoor

AIR® System – Technology The AIR® base station and transceiver are specific solutions, but the CPE in customer homes is standard and can be managed like business-as-usual The base station is an essential part of the AIR® Last Mile wireless point-to-multipoint system. It uses microwave based transmission and supports frequency bands between 2 and 42Ghz. By using carrier aggregation it supports channel width of up to 1 000 Mhz. As a result the throughput capacities are up to 41 Gbps per BS (DOCSIS) and 18 Gbps per BS (LTE). The base station is connected to the operators core network and broadcasts the signal to homes using AIR®. The transceiver is the counter part of the base station and is located at the customer premises. It is essentially a bi-directional parabolic microwave antenna (sattelite dish) and an outdoor unit. One unit is required per home, or a common unit can also service an apartment block with multiple homes. This unit down converts the AIR® signal and feeds it into worldwide used Docsis/LTE standard equipment inside the homes.

AIR® System – How it works? AIR® transceiver AIR® FDD system uses frequencies between 2 GHz and 42 GHz - with reach up to 50 km - AIR® Base Station CPE RF interface Original signal AIR® transceiver AIR® transceiver RF interface Original signal ORIGINAL NETWORK IP Core Network, Internet, TV, VoIP, … DOCSIS or LTE platform CPE CPE 12

AIR® System – How it works? 2. The signal is distributed via Point to Multipoint base station 3. Use of transparent wireless bridge instead of physical cable/fiber 4. At customer premises the signal is received by transceiver and converted to the original signal frequency The transceiver is bidirectional – i.e. converts signal from CPE to AIR® frequency AIR® BS 1. At the base station the input signal (DOCSIS, 4G/5G) is converted to another frequency (e.g. from 2 GHz to 42 GHz) AIR® TS 6. The original network CPE is used at customers premises to deliver services Original network IP Core Network, Internet, TV, VoIP, … Docsis or LTE platform CPE 7. CPE is seen in the network as it would be connected to original network (DOCSIS cable or 4G/5G) 13
