We keep networks working
Our mission is to build a network that lasts and makes your IT staff look like heroes
Every wired network starts with its cable infrastructure. Ultimately the cabling infrastructure controls the reliability and capacity of the network. Designing and building an effective and efficient network infrastructure is a highly complicated and technical job. And that is where the cabling experts at Omaha Communications can help.
We will survey your physical premise design a wired network infrastructure cabling that meets your organization’s specific needs and requirements.
Every network line is toned, tested and labelled to ensure a reliable and trouble-free network
Omaha Communications is a leading provider of affordable network wiring and structured cabling solutions. We specialize in network wiring, copper cable (Cat 5e, Cat 6), fiber optic cable, 新办公室布线, cubicle wiring, remodelling wiring, data drops, voice, data, security camera wiring, and any other IT wiring.
Every network line is fully terminated, toned and tested to ensure reliable network operation. We work directly with end-users and we subcontract for General Contractors and Electrical Contractors as well.
Network services and cabling
Whether it is a complete warehouse build-out or just adding an office cubicle – Omaha Communications can solve your network infrastructure problems.

Selecting a network cabling installer
When you need new structured cabling installed in your business it is time to select the right installer. But what should you expect from your design and installation team?
Every cabling design and installation project is different. But whether it is a campus-wide project requiring backbone cabling along with horizontal cabling or a simpler single building project there are certain installation team traits and actions that can tip you off to whether or not a provider will meet your needs:
Power over Ethernet comparison
POE vs POE+ vs 4PPOE (802.3af vs 802.3at vs 802.3bt)
POE – the beginning
Power over Ethernet (PoE) offers many advantages over traditional power methods, including time and cost savings, flexibility, safety, reliability, and scalability. POE also is a low voltage power source and does not require compliance with high voltage electrical codes in most locals.
The main drawback has been the limited amount of available power. Initially, 802.3af – the first POE standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) provided 15.4W of power and was sufficient for IP phones and other simple applications at the time. But as more complex applications entered the market, there was an increasing demand for more power.
POE Plus and Internet of Things (IoT)
Then in 2009, the (IEEE) released IEEE 802.3at also known as POE Plus (or POE+). POE Plus specifies 30W of power at the PoE source and 24W at the device. POE Plus provides much more flexibility for the burgeoning market for IoT (Internet of Things). The Internet of Things (IoT) refers to the massive influx of new devices that require power and network connectivity and help connect all aspects of our daily lives.
All kinds of devices are coming onto the market which requires power and data and was not anticipated by the original POE standard. This includes things like smart thermostats, smart doorbells, IP cameras, IP based alarm systems, Internet controlled lighting, and Wi-Fi access points. POE Plus can provide power and data connectivity simultaneously to these devices.
What is 802.3bt – 4PPOE?
Power Capacity of the 3 POE Standards
To address the need for more power, the IEEE introduced IEEE 802.3bt in 2018. IEEE is also referred to as 4PPOE or “BT”. 802.3bt expands the maximum PoE power available, pushing the power limit of power sourcing equipment (PSE) to 90W and powered devices (PDs) to 71.3W. This new standard achieves this by utilizing all four pairs of structured wiring. Additionally, IEEE 802.3bt supports multiple PoE classes and is backward compatible.
The 802.3bt standard is likely to be the highest power POE standard for some time. Not only does the standard run up against engineering challenges (it already uses all four pairs of wire to carry power), it also confronts regulatory issues since 90W is very close to the maximum amount of power allowed to send over the wire without having to comply with the standards and regulations required for high voltage wiring.
802.3bt meanwhile does serve the needs of certain high-power devices. These include motorized PTZ (Pan Tilt Zoom) security cameras and Hi-Power Wi-Fi Access Points. 802.3bt also provides enough power to charge phones, tablets, and even laptops.
