| Introduction: |
| |
Unlike many other wireless technologies, iDEN™ is a proprietary technology developed
by Motorola. While less widely deployed than other technologies, iDEN™ was the first to bring “push-to-talk”
to a sizeable market.
The goal of this intermediate-to-advanced course, which assumes some existing familiarity with iDENTM, is to undertake
an in-depth exploration of all aspects of the iDENTM technology. Discussed are issues related to the design, operation,
optimization, and troubleshooting of iDENTM networks – including the major parameters and the associated tradeoffs.
The course will allow you to evaluate solution approaches, anticipate performance problems, and identify ways of
resolving them before they start to affect the network performance. |

| Audience: |
| |
| Technical personnel with some prior exposure to iDEN™ or other 2G wireless technology who wish
to study iDEN™ in depth. |

| Prerequisites: |

| Customize it: |
| |
| This 4-5-day iDEN™ course will be customized to your needs and specifications. Eno.com will
assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless
training. They will typically have a broad and general course, one size fits all, already developed and just put
your organization?s name on the title slide. This minimizes their effort and time investment. At Eno.com, every
course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really
need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit
you into our standard, one size fits all, class. |
