Background – started smart antenna research in Silicon Valley and continued at the Hong Kong Applied Science and Technology Research Institute (ASTRI) incubated by the Hong Kong government in 2002. Adaptive interference control, US patent application no. 11/842,864 Multi-function wireless systems and methods, US patent application no. 12/470,537 WLAN access point with extended coverage area, US patent 10/903,911, exclusive from ASTRI Low cost, multi‑beam, multi‑band and multi‑diversity antenna for wireless communications, US Patent 10/720,716, exclusive from ASTRI Managing wireless communications using link space information, US Patent Application 10/274,834, exclusive from ASTRI Over 20 other patents available or pending in US and China. Operating mode: AP (dual-band) and bridge Access radio: b/g/n (8x8: 2) Backhaul radio: a/n (2x2: 2) Transmit power: 27 dBm (max.), 24 dBm (per chain) 2.4G antenna: internal 19 dBi array 5G antenna: external 20 dBi panel, 16 dBi sector or 9 dBi omni Power source: PoE injector Power consumption: 30W (typical), 65W (max.) Weatherproof: IP67 Operating temperature: -40 to 60 ºC Humidity: 100% (condensing) Wind loading: 217 km/h (survival) Dimension: 467 x 439 x 111 mm Weight: 8.2 kg without mounting kit Mounting: pole or wall-mounted Network interface: 10/100/1000 Mbps Ethernet port. 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.
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. Free download tutorial sweet home 3d bahasa indonesia pdf. 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.
Location: Jamaica, Caribbean Sea Application: Wireless broadband for residential and commercial users Product: A8, A2, B5 and C1 series Quote:“We are delighted to have partnered with Altai whose team effort in completing the network has been fantastic. We have proved that WiFi does not need to be confined to hotspots and can be deployed as a typical cellular wireless service.” Challenge: Lack of Internet outlet, power supply, difficult to acquire installation site Solution:A8 and A2 were installed at city for major coverage, C1 as CPE for remote user, A2 for wireless backhaul; end-to-end solution including service control, billing and pre-paid card systems Result: Over 300 A8 and A2 were installed in 30 major towns which serve over a million of the population The wireless Internet service is subscribed on a pre-paid basis.
The connection speed can be up to 10 Mbps. Local residences and tourists from US and the world can now enjoy Super WiFi service across the island using the same login name and password via their WiFi-enabled device. Location:Colombia municipalities Application: Wireless broadband for towns and villages – a National Plan to improve access to information and promote the mass use of Internet services through WiFi for hard to reach areas Product: A2 series Quote:“Currently the Vive Digital plan is considered a pioneer in the world for its great social impact.” Challenge: Lack of site and high tower Solution:A2 with external high gain omni antenna for flexible coverage; central management using AWMS. Installation sites started with municipalities, fire stations, hospitals, libraries and schools. Result: 220 A2 were installed in 80 towns The project is currently expanding to 40 additional municipalities. Location: East Palo Alto, California, USA Application: Wireless broadband for community users Product: A8 and A2 series Quote:“The total 3-year investment for city-wide WiFi networks can save almost 60% by using Altai system.
The payback period is shortened substantially, the retail service subscription fees is more competitive and the whole city-wide WiFi investment is more financially viable.” Challenge: Limited investment budget, need to cover 70% of 2.6 sq. Mile, large no. Of users Solution: Only 12 A8 were required to cover 1.6 square mile. Installation sites make use of roof tops of schools, churches, and other city based non profits Result: Each A8 covers 0.2 to 0.3 mile NLOS in distance A2 WiFi bridges are installed 1.24 to 1.86 mile away as backhauls. The throughput can go up to 35 Mbps.
Users typically have 2 or 3 Mbps throughput with low latency It provides coverage to over 35,000 residents. Local residents feel a more stable and higher throughput service during their Internet access There are smooth transmissions of triple play services including interactive applications, VoIP and video streaming. Location: Times Square, New York City, USA Application: Wireless broadband for public hotzone Product: A8 series Challenge: High rental charge at the most busiest district, short of power supply, high new site acquisition cost, high interference Solution:A8 was installed at a pole attached to the existing billboard, which shares the power and provides Internet connection.
The smart antenna technologies give good performance in highly interfered environment Result: Web surfers can log in on their laptop or phone at the Broadway Pedestrian Plaza, where there is an areas with tables and chairs Loaner laptops are also available on a first-come, first served basis.
