<h2>Key strategies for EDGE dimensioning</h2>

<p>The dimensioning of a network can be based on two different approaches:</p>


<ul>
<li><p>Available data capacity</p>
</li>
<li><p>Required data capacity</p>
</li>
</ul>

<div class="topic">
<h3>Available data capacity</h3>

<p>The operator wants to introduce EDGE to an existing network.  Dimensioning
determines how much traffic is available through the current system. The dimensioning
input is a pre-defined system configuration. The dimensioning output is available
traffic volume with a defined performance level. Alternatively, the operator
can calculate available capacities for different alternative configurations.</p>

<div class="topic">
<h3>Required data capacity</h3>
</div>


<p>The operator wants to design a network that supports the defined amount
of traffic and targeted performance level. The dimensioning inputs are traffic
volume, type, and performance requirements. The dimensioning output is the
needed amount of traffic dependent HW and associated SW configurations.</p>
