Challenges
The cost of backhaul is one of the biggest pain points for mobile carriers worldwide. The advent of new access technologies such as 3G and 4G, coupled with more users with increased usage minutes, is creating the need for more cell site deployments with smaller footprints. As more cell sites are added to accommodate the growing mobile voice and data traffic, finding cost effective backhaul solutions that are reliable, quick to deploy, high-capacity, and generally available can be a major challenge.

Furthermore, the growth of IP traffic carried in the network core with the advent of technologies such as UMTS and EVDO, including Voice over IP (VoIP), means that the legacy TDM based network infrastructure will not be the most ideal choice for interconnect and transport, since they do not scale cost effectively. Carrying IP traffic natively via Ethernet interfaces eliminates the need for conversion equipment, and lowers overall infrastructure costs.

Benefits
Own and control the infrastructure
Wireless backhaul solutions from Exalt eliminate the reliance on leased line facilities and provide full ownership and control of the network backhaul infrastructure without recurring costs or support dependencies.

Quick to deploy and service
Installs in days, not weeks or months.

Lowest total cost of ownership
Exalt provides the most cost effective backhaul solution compared to leased line, fiber, and even existing wireless alternatives, resulting in the lowest cost per Mb/mile in the industry. There are no recurring costs, installation is simple, and the upfront capital investment rivals any alternative on the market. Smaller, inexpensive grid or flat-panel antennas mean minimum tower rental costs, minimum wind-loading and inconspicuous appearance. Furthermore, in many cases the transmission infrastructure can be reused!

High availability
With 99.999% availability and guaranteed throughput over distance, Exalt products offer carrier-class reliability over leased lines or other wireless solutions under similar conditions.

Spectrum management and interference avoidance
Challenging interference conditions may be overcome with Exalt’s flexible spectrum management capabilities, allowing fine tuning across the entire band and variable channel bandwidths.

TDM to IP service migration
All Exalt wireless backhaul systems include a minimum of four T1/E1 TDM ports as well as Ethernet 10/100BaseT interfaces. TDM capacity can be easily increased for cell site interconnect applications without the need for external multiplexers, while providing capacity to all IP data and emerging IP voice and video services. TDM capacity can be seamlessly migrated from TDM to IP as needed without overhauling the wireless backbone.

Carrier class –more than market leading availability
Exalt wireless backhaul all-indoor products feature 1RU or 1.5RU form factor for optimum space-saving rack installation. In addition, low power consumption, 20-60VDC wide-mouth power supply, and guaranteed performance over temperature up to 65 C make Exalt wireless backhaul products true carrier-class solutions.
