Transforming Wireless Backhaul to Support Future Demand

By Susan J. Campbell

Telecommunications carriers know the future is in IP/Ethernet networks. But the existing infrastructure of many telecommunications companies has to be considered before they know if they’re capable of going that route.

As captured on this Transition Networks (News - Alert) page, the wireless backhaul relies on getting data to the network backbone. In fact, it’s essential. In getting to this point, telecommunications carriers must consider their network capacity and the required data speed to establish quality connections.

Mobile and fixed networks might have to be converged to pull off a successful augmentation, which means the timing of the synchronization is extremely important to carry out a cost-effective transition.

Wireless backhaul depends on a variety of infrastructure elements, whether it’s microwave or satellite, Ethernet tunnels or PacketBand devices, or other options. The important consideration here is that not every carrier is going to have it.

In some cases where packet networks are not cognizant of clocks or clocking, PacketBands can be used to enable TDM, IP or TDM over Ethernet services. Given a reliable clock source, a PacketBand can reach out to PacketBand devices at the other end of the network, providing a secure wireless backhaul.

While the TDM equipment takes in the steady clocks from the PacketBand, all the devices sync nicely. Stability is key in using PacketBand devices, and offers great recovery.

Latency and delays are limited in this method, as the TDM devices “perceive” the traffic as flowing continuously and steady, exactly like a point-to-point connection would communicate. This flow is essential to the success of wireless backhaul.

TDM over IP using PacketBand can help get rid of the need to lease T1s/T3s, which can help to drastically reduce operating costs. It’s a transparent process using protocols or signaling, which supports proprietary signaling and other features. It’s compliant with SAToP and CESoPSN, and offers a quality voice signal across the entire network. It also requires no forklift upgrades to your infrastructure.

PacketBand devices such as Transition Networks’ ISDN-1B can provide low-cost migration to IP networks for existing infrastructure. It compensates for jitter and packet delay variation and has a low latency and processing delay. It is compact and will fit into a rack mount. It also includes SIP server options for centralized call routing.

The PacketBand ISDN B-4 can transmit all data and voice protocols over packet networks and is completely transparent to all data formats. It features a configurable packet size and can re-order packets. Users can create routing profile schedules for different times of the day or the week.  The device also features 10/100 base Ethernet ports, three of which go to local Ethernets and one that goes to WAN.

With the increasing demand for the wireless backhaul to support recent market trends, Transition Networks is working to develop the necessary next-generation technologies to support network needs.
