10  8x8 MIMO technology  Designed to overcome inherent limitation of WiFi  Designed for challenging large outdoor and indoor environments Super Smart Antenna MIMO Transmit MIMO Receive

11  Boosts performance – Altai has developed an advanced smart antenna technology that is part of its Super WiFi base station family and boosts the performance of any standard WiFi client  Unique design – Altai’s patented smart antenna technology relies on a uniquely structured 8-element antenna array and a proprietary signal processing algorithm  Smart antenna – The user signal information is received through all the 8 antenna elements in the array, much higher in antenna diversity  Smart signal processing – The smart antenna technology processes the signal in real time and forms and focuses a high-gain beam toward the WiFi client  Super antenna diversity – In addition, it employs a signal phase alignment to obtain angular diversity – based on its 8-antenna array and its multiple independent radios  Better link budget – The powerful 8-antenna array also empowers the 8x8 MIMO signal processer that is part of Altai’s base stations, providing further signal gain in both the uplink and downlink 8x8 MIMO Technology

12  Super coverage – Altai smart antenna technology gives standard WiFi clients much longer ranges, more uniform area coverage, and the best indoor penetration  Super capacity – Altai’s 8x8 MIMO technology provides 5 times the median throughput than the standard 3x3 MIMO in complicated NLOS environments  Super efficiency – Altai AirFi improves WiFi cell efficiency with smart WiFi- based throughput optimization by a factor of 2, even with a large number of concurrent connections Benefits of 8x8 MIMO

13  The 8x8 MIMO technologies provide the following advantages  5 to 10 times larger in coverage, as compared to standard 3x3 MIMO AP in the market  Dynamic beam directing towards the WiFi client, which increases the link gain by at least 14 dB, as compared to a standard access point  Directed beam towards the user suppresses interference coming from all other directions Super Coverage A8n series cover almost identical 3G/4G cell 3G/LTE Cell

14  Altai uses two different technologies concurrently, increasing its WiFi base station capacity by a factor of 10:  Altai’s patented smart antenna technology – higher antenna diversity supports stronger the signal strength and hence throughput at distance, improving the median throughput by a factor of 5  Altai’s AirFi technology – a throughput optimization algorithm implemented at the WiFi layer, increasing its average efficiency and capacity by a factor of 2 and more Super WiFi Capacity Transmitter Smart antenna array Receiver Target receiver Interfering receiver Target data stream D/L Mixer (to IF/baseband) D/L Mixer (to IF/baseband) A/D D/L Mixer (to IF/baseband) A/D 1 2 M Adaptive algorithm Weighting Array ∑ w1w1 w2w2 wMwM + + - Output signal Ref. signal Error

15  Automatic channel selection selects the channel with the least interference  The focused antenna beam attenuates interference coming from all other directions Super Interference Immunity Standard AP A8n Multiple-sector coverage Single-sector coverage Interfering AP Interfering AP When the AP is interfered by adjacent site, the whole omni sector is affected When the base station is interfered by adjacent site, only one sector affected and other sectors can still work properly

24 Applications

25 1. Mobile Site Co-location for 3G/4G Data Offload Altai A8-Ei super WiFi base station co-locating with CMCC mobile site

26 Mobile Site Co-location for 3G/4G Offload Application A2 series wireless backhaul Co-location at tower using 3 x A8-Ein Co-location at rooftop using 3 x A8-Ein Mobile BTS & A8-Ein Mobile client 3G + WiFi coverage L2/L3 Network

27  5 to 10 times coverage – using 8x8 MIMO smart antenna technology, as compared to most 3x3 MIMO in the market  Installation is possible in limited space – as close as 0.5 m to the 3G/4G antennas is possible when the installation space of mobile site is limited  Super interference immunity – even installed at close proximity to 3G/4G antennas, no gradation to both the cellular and WiFi equipment; whereas most others in the market require at least 10 m separation  Fast deployment – just plug-and-play; much less site acquisition, setup and radio planning works; pay as you grow  10 times capacity – the smart antenna technologies improve the median throughput by 5X, and the Altai AirFi optimizes the average throughput by 2X  Lowest TCO – as low as 30% of investment as compared to using standard AP; only 10% of site requirement, but 10X faster time-to-market deployment Benefits of Super WiFi 3G Offload by Co-location

28  Top two cost elements, Site and Backhaul costs, added up to 58% of TCO  Altai 3G offload by co-location can lower these costs significantly  Savings in CAPEX and OPEX – including site acquisition, site set up, radio planning, site facilities reuse e.g. site rental, backhaul and power supply TCO Cost Analysis

29  Using Altai Super WiFi co-location can reduce the cost for every cost element  Saving in TCO total cost of ownership could be up to 68%! TCO Cost Analysis

30 2. Wireless Broadband Application U1 A2 wireless backhaul C1n 2.4G CPE A8n or A2 series Residential users C1an 5G CPE Dual-band access C1an Commercial users C1n repeater Mobile users, travelers 5G PTP links C1an

31  Broadest coverage – using A8n series for large coverage supports up to 1.7 km in range, extendable to 4 km with a C1n (2.4G) or C1an (5G) CPE  Lowest cost of deployment – traditional Internet access provisioning by copper wire or fiber is cost prohibitive in sparsely populated rural areas. The wireless access equivalent using A8n-C1n is a very cost effective solution to deploy wireless broadband in rural areas  Short deployment time – while traditional fiber takes months to deploy, wireless access just need a few days; and you need to pay as you grow  High bandwidth broadband – with the use of a pair C1an for PTP bridge, service provider can offer high speed broadband for commercial users up to 120 Mbps download and upload per PTP link  Support mobile users and travelers – beside residential and commercial users, the same WiFi network can also serve mobile users and travelers, who can subscribe the WiFi service on needed basis by means of prepaid card Benefits of Super WiFi in Wireless Broadband

32 3. Private Network Applications A2 series wireless backhaul with redundancy Mobile terminal A2 series Container stacks A8n or A8 series Airport MRO Vessel Warehouse Management servers Universities and schools Hotels and resorts Mining, gas, oil and manufacturing Container ports and marinas Video surveillance Railway logistics

33  Both outdoor and indoor coverage – many private networks require not only indoor but large outdoor coverage in one network, e.g. airport, container port, university campus, manufacturing plant and resort etc.  When other WiFi doesn’t work for you – the Altai Super WiFi can perform extraordinarily good in NLOS environments that are blocked by metallic stuffs, e.g. quay cranes and container stacks in container ports, hangars and cockpit in airport MRO, machineries in manufacturing plants etc. Custom made enclosures for hazardous and explosive proof environment  Backhaul resilience – A8n can provide backhaul redundancy and failover switching and recovery for mission critical applications e.g. contain port, airport, logistics etc.  High bandwidth surveillance – the C1an can be used as low cost PTP bridge which supports high definition surveillance up to 100 Mbps  Boost up production efficiency – many production systems already support WiFi terminals; A8n or A2 can be used to build the wireless network in different scales to improve the efficiency and convenience of production system such as WIP, RFID and bar code etc. Benefits of Super WiFi in Private Networks
