Korenix Powers WiMAX Base Stations with JetNet 4706/ 3706 PoE Switches

Enterprises, Internet Service Providers, and Mobile Network Operators are all looking for cost-effective ways to move voice and data among multiple, separate locations at broadband speeds. Copper and fiber optics solutions often fall short due to up-front costs, recurring leases from telecommunications companies, and a lack of flexibility to scale with the operating organization. Broadband Wireless Access (BWA) in WiMAX technology has emerged as a means to fill these gaps and to provide a lower total cost of ownership than wired solutions.

To assure the reliable and the long range wireless communication between WiMAX Base Station Unit (BSU) and WiMAX Subscriber Unit (SU), the solution demands a high power consumption and 48VDC power supply. It provides a cost effective solution to service providers by connecting backhaul of telecommunication in WiMAX to replace the current wired leasing line.

The JetNet 4706/ 3706, Industrial PoE Plus managed switches, support 30 Watts per PoE port with wide power input range 24V~50VDC, which sufficiently meets the power requirements of WiMAX Stations. For the managed JetNet 4706 series, each of the four PoE ports can be configured on weekly schedule by hourly basis. PoE on/off can also be controlled remotely via SNMP or web (JetNet 3706). The two uplink ports (100M TX or 100M FX) can be configured as Rapid Super Ring ports, recovering network failure in less than 5ms. JetNet 4706 also supports comprehensive and user-friendly management interfaces, such as SNMP v1/v2/v3, RMON, Web interface, Telnet, Cisco-like CLI via RS-232 console.

JetNet 4706/ 3706 series use IP-31 aluminum housing to carry out superior heat radiation, robust and light weight. It also provides an enhanced protection for the non-stop operation under hazardous operating temperature, -20~60° and 10%~90% humidity.

JetNet 4706/ 3706 series are simply the best choices to build up an intelligent, power over Ethernet management, wireless services and cost-effective IP surveillance infrastructure.

High Power Forwarding System
The IEEE802.3af Power over Ethernet standard specifies 15.4w power budget for PD system. However, 15.4w is simply not enough for some applications. JetNet 3706/ 4706 follows two PoE mechanisms, IEEE 802.3af and High Power pre-standard IEEE 802.3at for 30W power budget. To recognize the PD classification ID, a powerful micro-processor is installed in JetNet 3706/ 4706 for power detection, classification, powering and disconnection processes. The JetNet 3706 / 4706 can power PD with different power level in PD classification ID replied.

Power Budget & Weekly Scheduling PoE Power Control
To achieve the energy saving, the JetNet 4706/ 3706 also implements an excellent PoE power limit control mechanism, such as PoE port disable/enable, power limit mode selection for IEEE 802.3af standard, manual configuring power budget accordingly to each port’s power consumption. JetNet 4706 provides a weekly scheduling PoE Power Control to conserve energy and extend the powered device life time. JetNet 4706/ 3706 implements the scheduling control for PoE similar to UPS, Uninterruptible Power Supply. It provides hour-by-hour power control on a weekly schedule; each port can be configured with different rules for different hours of the day and different days of the week. This feature significantly improves power usage and meets economic resource management requirements.
