Rete l i t SpA i s a prov ider of broadband

connectivity solutions and infrastructure in the

wholesale market in Italy.

Retelit holds the national fiber optic network of

over 6,700km with connecting 200 cities andmajor towns

With 10-year experience as a wholesale operator,

Retelit was eager to move into the wireless field.Subsequently, Retelit allocated €23 M to acquire

a 42-MHz 3.5G WiMAX license.

In August, 2008, Retelit chose Huawei as the sole

source for E2E devices and service to launch the

first 16e network in Italy.

Irrespective of the distance between Huawei ’s

WiMAX R&D center and their European customer,

Huawei designed an optimal solution in response

to Retelit’s precise requirements and deliveredthe network well ahead of schedule.

On 30 September 2008, the COO of Retelit sent

out a notice through the WiMAX network and

announced that the first 16e WiMAX network

Huawei’s Solution & Retelit’s Benefits

High Performance

In contrast with most conventional requirements,

Retelit uniquely required the core network to

control the QoS profile for each end user.

Normally this would have dictated additional

research, design and development as well asadded cost.

Fortunately for the operator, Huawei’s built-in

Authentication, Authorization, & Accounting

(AAA), WASN and BOSS work with standard

protocols to permit highly flexible authentication

and accounting methods, coordinating with the

existing Retelit software system to provide more

available solutions for the operator.

Huawei’s, DBS3900 now provides Retelit with

the highest PAE in the industry, with multicarrier

and 4T/4R. Throughput and coverage fully meetRetelit’s requirements and deliver a better end-

user experience.

RTN 600 radio transmission system is a split-

mount digital microwave transmission system

Strong delivery capability

Huawei has developed a customer-oriented

platform that ensure a quick response and time-

to-market delivery. For this project, Huawei

assembled a professional team and held weekly

meetings with Retelit.

Less than eight weeks after issue of the original

purchase order, Huawei enabled launch of

Retelit’s WiMAX network.
