Wireless communications decision-makers face a daunting array of choices in evaluating new solutions for mobile data or SCADA communications systems. Whether you are looking at a fixed-data system for a utility operation, a mobile public safety system, or any number of wireless data applications used in enterprises today, you are likely to encounter a variety of myths and misconceptions.

Below are some of the most common myths surrounding wireless data networks as well as some insights for taking an informed approach to your next wireless design decision:

Myth #1: A Public Carrier Is Obligated to Keep Your Network Operating and Safe

In fact, public carriers have no obligation whatsoever to keep individual customer interconnected systems up-and-running, let alone safe.
The carrier can make changes to their system at will and with little or no advance notice. Subscribers have no control over their networks. Having command and control of your data network is a crucial management element, particularly in emergencies or during network outages.  

A private wireless network gives users the control they need to keep critical communications safe. From dispatch operations and priority messaging to controlling technology migration, private wireless systems allow organizations to remain in charge of their networks and their network maintenance. Administrators can control who is on the network and their access to information. This is critical for keeping systems safe, secure and fully operational.

Myth #2: A Private Wireless System Is the Most Expensive Option

When funding is tight, it is tempting to compare monthly costs of public versus private data networks and conclude that public networks are cheaper. What gets lost is the reality that operating a private network can actually cost less than the compounding monthly costs of a public service. While a private wireless system has more up-front requirements, there is a minimal monthly burden once the system is operational. Factor in the expected life of a typical communications system and compare the costs over the long haul, and you will find a private network is the more cost-effective option.

Myth #3: I Can Automatically Expect Seamless, Uninterrupted Coverage Throughout My Operating Area

While public networks are set up to cover the majority of space over a large geographic area, they are not necessarily arranged to provide complete coverage in any single place. Rural areas may not have the public network coverage that critical communications require, and in certain cases performance suffers. While public systems are most often found in densely populated areas or along major highways, private networks can be constructed to meet the needs of specific boundaries.

Myth #4: More Features Mean Better Service

Most public networks offer a variety of attractive capabilities, but it should be noted these features are often aimed at consumer, rather than commercial, mission-critical applications. When it comes to making a wireless choice, the right features - not the most features - should guide your selection. And, since no two organizations are exactly the same, the flexibility of a private network is a distinct advantage over a one-size-fits-all public network.

An organization can accommodate many special user requirements on its private system. For example, the private system can accommodate an emergency override function that gives a priority connection in critical situations or a vehicle location function for efficient dispatching. Both are handled efficiently on a private network.

Myth #5: Network Capacity Should Match the Usage Rate

The truth is, there is no single usage rate for a network. Instead, traffic can vary greatly. This is important to note as high usage, and associated congestion, can negatively impact performance on a public network. Time of day can affect usage, as can emergencies.

A private network can be designed to handle varying loads of communication users. Redundancy can also be built in to protect a private network from being overloaded or brought down in a critical situation.

The bottom-line in making the right choice? Know Your Needs
As many utility and public safety decision-makers know, bells and whistles do not determine the success of a wireless data system.
The right choice is the one that best suits your particular needs.

Public networks provide subscribers with a host of features and advantages for non-critical applications. Private wireless systems, however, offer the level of dependability and features required for mission-critical applications. Knowing your needs and having a clear understanding of the realities of wireless data communications are the best strategies for ensuring that your system delivers on its promise, today and well into the future.
