Altai recently participated in this regional event – India Telecom 2010. India Telecom 2010 provided a platform for industry players from South Asia to come together and explore the vast potential of the latest ICTs.

Altai showcased our latest Super WiFi equipment – the A8-Ei Super WiFi Base Station as well as the A2e Access Point. The Altai A8-Ei’s superior long range coverage allows immediate WiFi provisioning for 3G operators to offload data traffic from their 3G networks, while the A2e is for super long range bridging and sector area coverage. We received an overwhelming response from potential customers and all of them were impressed by the superior performance of the Altai Super WiFi products.

In India we have deployments in campus, hotel, terminal ports and we continue to deploy our innovative wireless broadband solution in the South Asia region.

Altai Technologies has recently launched its A2e Access Point/Bridge. Working as either an access point, bridge or both in both outdoor and indoor areas, this latest addition to the Altai Super WiFi product portfolio delivers long range point-to-point or point-to-multipoint high throughput bridging and smaller sector area access coverage.

The A2e is designed to be used in Altai’s Super WiFi system to provide long range bridging, fill in areas of low or blocked signals, increase the system capacity and extend WiFi coverage. Working as access point mode, the A2e can achieve up to 800 m in the line-of-sight environment, while working as bridge mode it can provide up to 25 km point-to-point super long range bridging.

Key features of the Altai A2e include:

• Multi-operating modes: access point, bridge, repeater or CPE mode
• Built-in 2.4 GHz high gain panel antenna for high capacity directional AP applications
• Connectors for external 5 GHz high gain panel or omni antennas for long range high throughput point-to-point and point-to-multipoint bridging
• 2 x 2 MIMO for both 2.4 GHz (802.11b/g/n) and 5 GHz (802.11a/n) radios
• Concurrent 2.4GHz and 5GHz operation
• IP 67 rated carrier grade product for both outdoor and indoor applications

The A2e has further strengthened Altai’s Super WiFi product family to provide a total wireless solution to service providers. Altai’s expanded family of Super WiFi products allows operators to select and deploy network elements that meet their specific networks and business requirements.

The type of Ethernet cable to be used in an outdoor deployment is critical. The Ethernet cable should be CAT5e or CAT6, outdoor rated, and shielded. Specifically, the following types of Ethernet cable should be used for outdoor installation: sFTP, FTP, or STP.

Using UTP Ethernet cable and / or an unshield RJ-45 jack are not recommended due to the increased electromagnetic noise level in outdoor deployments. Furthermore, using a shielded CAT5e Ethernet cable without using a shielded RJ45 jack at the base station and PoE injector may cause more problems than not using it. This is because if a shielded CAT5e Ethernet is ungrounded, it will act as a magnet for static charges present in the environment. Since the charges cannot be discharged properly through a shielded RJ45 jack, it may couple with the internal data or power lines of the PoE cable. As a result, the coupling of high voltages present on the Ethernet cable may damage the base station directly interfacing with it. Therefore, it is important to always use shielded outdoor rated Ethernet cable together with shielded RJ45 jack in outdoor deployment.

The only difference between crimping an UTP cable and a FTP cable is that the latter has a small wire under the foil. This wire (preferably 2cm longer than other wires), also known as the drain wire, should be wrapped around the outside of the shield when installing the shielded RJ45 plug. It is very important to have direct contact between the foil and the shield of the RJ45 connector.

The following figure shows a shielded, metal-enclosed RJ45 connector. First the boot is slid onto the cable, then the cable shield and drain wire are folded back, next the load bar is loaded with the eight inner cable conductors, then the load bar/cable assembly is inserted into the connector housing and crimped. Finally, the boot is slid over the assembly for additional strain relief.
Here are some more tips to improve the effectiveness of your surge protection scheme for fighting against lightning and power surges:

• Keep cable runs as straight as possible.
• Always run outdoor PoE cable inside of the mounting pole if possible. The mounting pole will act as electromagnetic insulation and help passing surges to ground.
• Use PoE cable and RJ45 plugs that are shielded and are rated for outdoor or direct burial applications;
• Test the conductivity of the grounding system to ensure the installation is solid and electrically capable of grounding any ambient surge or static.
