The Altai C2s Dual-band 2×2 WiFi AP/Bridge is specifically designed to offer carrier grade Wi-Fi performance at the market’s most affordable price point.
Altai C2s combines several technology breakthroughs to deliver unparalleled Wi-Fi experience and highly reliable and consistent services to mobile users:
• Superior RF and filter design, in conjunction with Altai’s interference mitigation algorithm, offers optimal capacity and interference rejection 
• Much higher TX power over competitions at the highest data rates allows up to 50% more coverage and capacity 
• Altai’s smart band steering and load balancing technologies allow Altai C2s to effectively utilize both 2.4GHz and 5GHz spectrums for supporting a large number of mobile users running bandwidth hungry applications

802.11n/ac, Built-in 2.4 GHz and 5 GHz Patch Antennas

Applications 
• In conjunction with AltaiCare and its powerful user access management, Altai C2s offers the most cost effective indoor or outdoor Wi-Fi hotspot solution for MNOs and WISPs 
• The low-cost Altai C2s, together with the controller-less, cloud-based AltaiCare and its payas-you-grow subscription model, are ideally suited for enterprises and SMEs that want enterprise features such as security and performance but not the price points associated with controllerbased solutions 
• With 5GHz as backhaul and 2.4GHz as access, Altai C2s is the perfect Wi-Fi CPE for WISPs. Combined with either A8-Ein (ac) or A3-Ei, the solution delivers Wi-Fi coverage up to 3km • The Altai C2s offers a low-cost solution for high capacity point-to-point and point-to-multipoint infrastructure backhaul for MNOs and WISPs, smart cities, and video surveillance applications
Altai C2s Dual-band 2x2 802.11ac WiFi AP/Bridge
- Best value in price/performance Dual band 802.11ac with extended coverage at the market’s most affordable price point
- Extended coverage requires fewer APs Up to 50% larger coverage minimizes the number of APs required for any Wi-Fi network
- Dual-band with 802.11ac 802.11ac delivers total data rate of more than 1 Gbps. This, together with Altai’s smart band steering and load balancing technologies, allows a Wi-Fi network to support a large number of mobile users running high bandwidth apps
- Best-in-class performance Superior RF and filter design, in conjunction with Altai’s smart interference mitigation algorithm, offers optimal capacity and interference rejection
- Superior antenna design Integrated high gain diversity polarized antenna design increases the effectiveness of MIMO for both 802.11n and 802.11ac
- AirFi optimizes capacity AirFi enhances Altai C2s’ capacity by optimizing client’s throughput based on its signal strength and traffic
- Flexible architecture Standalone, controller-based, or cloud-based management with AltaiCare
- Ease of deployment Zero configuration of AltaiCare allows a non-technical person to simply unpack and plug Altai C2s to Wi-Fi network. Furthermore, support for standard 802.3at PoE (via optional adapter) allows enterprises to use existing PoE switches
