Free Space Optic Solutions Remote Antenna Extension Application

SONAbeam™

> Distributed/Remote Antennas - Need

» Increased MOU’s (Bundle of Minutes rate plans) and upgrade to GPRS/GSM require the installation of more antenna locations

» Wireless carriers have urgent market need to eliminate “dead spots” – “Can You Hear Me Now?”

» Capex crisis have reduced available capital for construction of much needed BTS’s

» Coverage “Crisis” Number 1 cause for churn

» Availability of roof/site/space rights for placement of antennas limited and recurring monthly operational expenses are high

» Wireless Carriers need to triple the number of cells sites within the next four years

> Benefits

» Capex – 80% less than cost of a new cell site

» Opex- Small footprint of remote antenna dramatically reduces roof-right, tower, and infrastructure costs. Total going forward savings dwarf Capex savings. Also, backhaul costs eliminated using remotes

» Fiber available in only 25% of desired remote antenna locations*

» Only SONAbeam (free space optics) can fill the gap with its ability to transport the required 1.482 GB capacity. Microwave cannot do it. Only fiber and FSO can

Remote Antenna Extension - Topology

> Answer: SONAbeam 1250 & ADC Digivance

» ADC Digivance converts 25 mhz of RF spectrum into a digital pipe of 1.482 Gb of bandwidth

» SONAbeam 1250 is the free space optical transmission system that transports the 1.482 Gb bandwidth pipe

» Combined, the system extends the full capability of an existing (and very expensive) BTS to a remote distributed antenna location within 1 mile of the hub BTS location

» Interoperability testing complete and 100% successful using SONAbeam 1250 and ADC Digivance. Tests conducted by ADC.

» Benefits Speed of deployment Reduce costs of new antenna deployments by 90% and more

compared to costs of dark fiber - build or lease Reduce operational expenses going forward

What our customers are saying

US Army

CA & AZ State Govt’s

“I am very pleased with the installation … I am more than willing to recommend both the fSONA product and CSG Wireless to any of your potential customers.”Arizona State Police

“When compared to other products tested, it proved to be both superior in overall quality of hardware and in transmission capabilities.”Major European Carrier

“We just came through a winter season filled with snow, rain and fog. The weather never caused any problems… We made the right decision and are very happy with the SONAbeam optical link.”Canadian Distributing & Warehousing Company

“We are so glad to inform you that during the tests, the impression that each customer had for FSO changed in a very positive way in general and in particular for the fSONA product line. All got the same conclusion: SONABeam is the best FSO in its class.”South American Systems Integrator

>> SONAbeam™ - Product of the Year

FSO is here, it works, and it can provide a high-speed, point-to-point link without

the need to lay fiber or acquire a radio spectrum

license. While several vendors produce excellent

FSO equipment, fSONA stands out as 2001's most innovative. Wireless links always mean a three-way

trade-off between capacity, range, and reliability, but the SONAbeam™ excels in

all three.
