Wi-Fi Hotspots and Data Offloading


Wi-Fi Offloading and Hotspots

The ever-growing bandwidth demand from smart phones and tablets presents a major challenge for mobile operators with already congested 3G and 4G cellular networks. Carrier Wi-Fi hotspots are a cost-effective method to offload data and video traffic from 3G and 4G networks, as well as to offer subscribers value added services or premium content services.

Wi-Fi with best effort Ethernet backhaul for data offload can be deployed anywhere people congregate. This includes stadiums, airports, hotels, restaurants, hospitals, schools, and office buildings.

Challenges Deploying Carrier Wi-Fi Hot Spots

One of the challenges with any access network is the 100 meter distance LAN limitation of UTP cabling. Fiber access networks overcome this distance challenge, but Wireless Access Points typically do not have fiber ports. In addition many Wireless Access Points are powered using Power over Ethernet (PoE), which provides flexibility in placing and installing devices, but this requires UTP copper cabling.

Switches that function as Power Sourcing Equipment (PSE) are often deployed to power Wireless Access Points. These switches will have a fiber uplink port and multiple RJ-45 PoE ports. The problem is that they are bulky, expensive, and consume a lot of power. This makes them difficult to deploy outdoors in a NEMA enclosure.

PoE Media Converters

OmniConverter PoE Media Converters function as copper-to-fiber media converters and as Power Sourcing Equipment (PSE), supporting both the PoE (15.4W of power) and the IEEE 802.3at PoE+ standard (34.2W of power).

The OmniConverter is a multi-port PoE media converter, available with a variety of port configurations including single or dual UTP and SFP ports. Dual fiber ports enable daisy-chain, ring, and redundant link topologies. Dual copper ports can provide power to one or two Powered Devices (PDs) using standard UTP cables that carry the Ethernet data. A PoE power reset setting disables the PSE power output for 2 seconds after the loss of fiber link to allow the Wireless Access Point to re-initialize.
