www.altaitechnologies.comwww.altaitechnologies.com
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
www.altaitechnologies.comwww.altaitechnologies.com
Super coverage – Altai smart antenna technology gives standard WiFi clients much longer ranges, larger 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
www.altaitechnologies.comwww.altaitechnologies.com
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
www.altaitechnologies.comwww.altaitechnologies.com
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

Broadest coverage – using A8n series for large coverage supports up to 1.7 km in range, extendable to 4 km with a C1n (2.4GHz) or C1an (5GHz) 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

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.

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
www.altaitechnologies.comwww.altaitechnologies.com
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
