� How the network works

Page 3: Building Greenfield Networks

Why do I lose the signal in the building?◦ Going through simple walls like wood or drywall we

lose up to 90% signal

◦ However, devices can compensate to a point by amplifying our signal many times over – that is how we are still able to receive the signal that we dowe are still able to receive the signal that we do

◦ Indoor coverage is Gold!

Local Sales Senior

Leadership Team Review

• Based on local knowledge

RF Engineering receives target

AOI

RF Engineering designs network

to meet coverage tasks

• Towers, buildings, or Based on population

Area of Interest is Designed by

HQ

• Based on local knowledge

• Must have XX areas covered

• Growing area of the market

• Targeted levels of coverage

• Towers, buildings, or raw land opportunities to build new towers (rare)

• Backhaul engineers design the connections between the towers and to the internet

Based on population density, income, etc.

Network Deployment

team makes site a reality

• Network Deployment team

Local Tech Ops team works with Commissioning

group to turn the site on

• Work with the commission

Network Operations

watches over it forever

Alarm will sound if it goes • Network Deployment team executes the following:

• Lease agreements

• Zoning

• Permitting

• Construction team builds the site including equipment , antennas and dishes

• Work with the commission team in Vegas

• Initial programming

• On air and transmitting

• RF team does a drive test

Alarm will sound if it goes out

Tech ops will go out and fix it

How much does it cost to build one tower?

$100 - $150k

Page 7: Building Greenfield Networks

Facts:Facts:Facts:Facts:• Have 6-12 channels per

market• Site has 3 antennas• Each site needs 3 channels • Each site needs 3 channels

to get started• Need an additional channel

for every 100 users in a sector

• Sites typically covers from .7 – 1 mile

Page 8: Building Greenfield Networks

Challenges:Challenges:Challenges:Challenges:• If two towers are using the same

channel and overlapping then it causes interference. It reduces coverage.

• Optimization is like picking your • Optimization is like picking your neighbors. We have to make sure that the RF signal goes far enough, not too far so that it interferes with the next tower.

• Each additional channel requires optimization to make sure that it serves only its intended area

Page 9: Building Greenfield Networks

What makes a NETWORK different?

One of our main competitive advantages is that we own our own backhaul from the sites – this is our way of getting the signal back to the internet

3G is currently using copper wire “T1” type lines at most sites, whereas GREENFIELD Wireless companies can have predominantly microwave backhaul –bypassing expensive fiber

We can effectively build a T1 bandwidth for $5 a month –which helps keep prices down for you to sell

How long does it take to build a network?

Sites can come on-air anywhere from 6 months to 2 years

If and when our customers demand more bandwidth, there is the flexibility to change

Page 12: Building Greenfield Networks

� Understanding how the network is designed, built, and maintained helps you:◦ Sell in the right areas

◦ Set the right customer expectations

◦ Have more happy customers that send referrals◦ Have more happy customers that send referrals

◦ Have less customers that pullback

◦ Make more money!
