Fiber isn't everything: Microwave's critical role in

North American backhaul

Thank you for joining us at this FierceLive! Webinar. We will begin

momentarily. The audio will be streamed live over the Internet, so please make sure

your computer speakers or headphones are turned on and your

volume is turned up.

During the presentations, you can submit your questions by filling in

the Ask a Question box at the bottom of this screen. The speakers

will answer questions at the end of the webinar.

Enjoy the presentation!

Fiber Isnt Everything:LTE Backhaul and IP Microwave's Critical Role

Agenda: LTE's impact on backhaul requirements

LTE backhaul options analysis (copper,fiber, microwave)

Leasing vs. owning backhaul Can IP-based microwave meet LTE

requirements?

Next generation IP microwave capacity

LTE's impact on backhaul requirements

Mobile network backhaul

requirements areincreasing dramatically

150Mbps per site in the

next 5 years, 450

average expected

Source: OvumNote: capacity was determined by adding the peak uplink anddownlink speeds for each technology

Initial deployments for LTE are being supported by cell-site backhaul capacity in the

range of 10150Mbps high areas will grow up to 300 Mbps

Backhaul media options for LTE

Copper has low cost but has capacity and reach limitations

Fiber is preferred due to its reliability and nearly limited scalability howeverdeployment costs are high and sometime prohibitive

Microwave provides low cost option quickly deployable option that meetsfuture LTE capacity requirements
