Cabling Considerations for High-Efficiency Wireless Access Point Connections
A new wave of Wi-Fi is here. The IEEE 802.11ax Enhancements for High-Efficiency Wireless (HEW). LAN standard1 has far-reaching implications with respect to cabling infrastructure design. Users can expect their current wireless speeds to appreciably increase by switching to Wi-Fi 6. Now more than ever, the specification of high-performance cabling supporting access layer switches and uplink connections is critical to achieving multi-Gigabit throughput and fully supporting the capacity of next-generation wireless access points.
This new standard is rolling out now in a number of large pilot sites. Nexsis have been working closely with the World Broadband Alliance to ensure we are at the forefront of this new wave of Wi-Fi technology.
Although Wi-Fi 6 radio chips are equally or more efficient than prior generation wireless chips, they are doing significantly more complex signal processing and the amount of power required to energize Wi-Fi 6 devices is higher than for any previous implementation. In fact, due to complexity, both Wi-Fi 5 and Wi-Fi 6 WAPs are unable to work within the 13-watt budget of Type 1 Power over Ethernet (PoE) and must be supported by either a direct DC power adapter or 30-watt Type 2 PoE remote power.
While safe for humans, Type 2 PoE remote power delivery, at an applied current of 600mA per pair, can produce up to 10°C (22°F) temperature rise in cable bundles and create electrical arcing that can damage connector contacts. Heat rise within bundles has the potential to cause bit errors because insertion loss is directly proportional to temperature. In extreme environments, temperature rise and contact arcing can cause irreversible damage to cable and connectors.
Fortunately, the proper selection of network cabling can eliminate these risks.
