Proxim Wireless Outdoor Router Protocol (WORP)

• Engineered from the ground up to optimize the performance of multi-stream voice, video, and data over wireless networks. WORP® is the foundation for the efficiency and security inherent in every Proxim Point-to-Point and Point-to-Multipoint system.

Scalability

• Proxim WORP® is designed to overcome the limitations present in many point-to-multipoint solutions based on the WiFi 802.11 MAC protocol. In 802.11-based systems, dense multi-node deployments suffer from packet collisions and subsequent retransmission, dragging down network performance. Even in systems with as few as two or three remote nodes, network performance can be affected by an excess of packet collisions.

Security

• Proxim WORP® offers multiple layers of security to protect valuable and private data during transmission. The proprietary nature of WORP® ensures that any device used to capture data must first be able to crack WORP® or use a WORP® enabled device as the decoding system. WORP® requires a Subscriber unit (SU) to register with the Base Station unit (BSU), using an MD-5 secret string in the authentication process. Without the appropriate MD-5 key, rogue Subscriber Units cannot join the network.

Quality-of-Service (QoS)

• Proxim WORP® enables sophisticated QoS management to enable effective optimization of the available network bandwidth. QoS in this instance means minimum and maximum data rates with programmable jitter and latency limits, and operating within the defined parameters for packet loss and data error rates.

Wi-Fi Hidden Node Problem

• Wi-Fi was explicitly intended for short-range indoor applications — the assumption that all clients can “hear” each other is evident in the Wi-Fi MAC protocol. Wi-Fi operates on a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) technique which means that each client device listens to the network and if it does not hear another device communicating, assumes the channel is clear and begins transmission.

Benefits and Goals:

• You want a second opinion for your Predictive or Verification WLAN RF Design.
• Your company has multiple sites and wants to reduce travel costs in the validation of all sites.
• Remote Wi-Fi troubleshooting.
• Optimized ROI on your Ekahau SideKick purchase.

Ionising Radiation

• Some electromagnetic waves carry such large quantities of energy that they can ionize particles of matter and consequently break down the chemical bonds between molecules. X-rays used for both diagnostic and therapeutic purposes (radiotherapy), gamma-rays (emitted by radioactive materials), and cosmic radiation, all have this ability and are known as ionizing radiation

Non-ionizing radiation

• Electromagnetic fields that cannot break down molecular bonds are called non-ionizing radiation. Many artificial sources of electromagnetic fields, by which we are surrounded daily (including radio signals), are non-ionizing. In other words, the quantity of energy they carry cannot break down chemical bonds within cells and tissues.

• The term “EMF measurements” is used when the measures of electromagnetic fields concern the impacts of these waves on the human body. In many occupations, there are lots of areas where employees are exposed to electromagnetic radiation or electromagnetic fields (EMF). These increased EMF levels have been triggered by achievements such as the growing LTE/5G wireless network, the increased amount of Wi-Fi radios in our living space, and the “industrial” Internet of Things (IIoT or IoT) or Machine to Machine communication (M2M). This is particularly true for offices and workplaces that are located in today’s high-tech cities, or near radar antennas, broadcasting, and cellular phone transmitters. Industrial plants were operations like smelting or welding while using high-frequency energy, and hospitals where a wide variety of medical equipment is in use that works on RF technology.

Exposure limits exceeded?

• In case the exposure limit is exceeded at a specific measuring point, we will need to take measures to mitigate the EMR to acceptable levels. First of all, we need to identify the source(s) of EMR and find out if they are originating outdoor or indoors. Once we identified the sources, we can take actions like disabling or relocating the EMF source or even use RF-blocking materials (foil, paint, or wallpaper) to decrease or block the EMR.
