Point to Point & Point to Multipoint

What types of wireless networks are there?


Point-to-Point (PtP) are wireless networks providing a direct link between two locations, using  wireless technology to transmit data over various distances.


Point-to-Multipoint (PtMP) are wireless networks involving a single central node connecting to multiple end points, using wireless technology  to transmit data over various distances. 

 

 

Why a wireless network over wired?


Wireless networks offer mobility, flexibility, and cost-effectiveness compared to wired networks. They require less infrastructure, are easier to set up and expand, and provide remote access from anywhere within range. Wireless setups are ideal for environments where mobility, scalability and convenience are essential.

 

 

 

Wireless PtP/PtMP

Wired

Installation

Requires line of sight for PtP; setup can be quicker than wired in certain scenarios

Requires physical cable installation; more time-consuming and labour-intensive

Mobility

Limited mobility; devices must stay within wireless coverage area

Limited to fixed locations due to physical cable connections

Scalability

Scalable to some extent, but may require additional equipment for expansion

Scalable with additional cabling and network infrastructure

Flexibility

Offers flexibility in device placement and network expansion without the need for physical cables

Limited flexibility; device placement and network expansion are constrained by cable locations

Speed

Wireless speeds can vary depending on factors like distance, interference, and signal strength

Wired connections typically offer consistent and higher speeds

Reliability

Susceptible to interference, signal degradation, and environmental factors; may experience downtime during adverse weather conditions

Generally more reliable with stable and consistent connections

Security

Wireless networks may be more vulnerable to unauthorized access without proper encryption and security measures

Wired networks are typically more secure due to the physical barrier of cables

Cost

Initial setup costs can be lower compared to wired networks, but ongoing maintenance and equipment costs may vary

Higher initial setup costs due to cabling and infrastructure requirements, but lower ongoing maintenance costs

Coverage

Coverage area limited by wireless signal range; may require additional equipment for extended coverage

Coverage area determined by cable lengths and distribution points

Interference

Susceptible to interference from other wireless devices, structures, and environmental factors

Less susceptible to interference since signals travel through shielded cables

Latency

Wireless networks may experience higher latency compared to wired networks, especially over longer distances

Wired networks generally offer lower latency, ideal for latency-sensitive applications

Frequently Asked Questions

Do wireless links require clear line of sight?

Yes, PtP and PtMP wireless links typically require a clear line of sight (LoS) between the various points for optimal performance. This will ensure the radio waves travel with minimal obstruction and signal degradation. Clear line of sight will also allow higher data rates, lower latency and reduced interference. Understanding the specific environmental conditions and technological capabilities can help in designing effective and reliable wireless networks even in challenging scenarios.

What are the typical ranges for PtP/ PtMP links?

PtP networks can achieve ranges up to several tens of kilometers, depending on the frequency and power used. PtMP network ranges are generally shorter, often a few kilometers, due to the need to maintain signal quality for multiple endpoints

How do you ensure clear Line of Sight (LOS) for PTP/PTMP installations?

- Conduct a site survey - Use mapping tools and software to plan the deployment - Consider the height of antennas and obstacles in the path - Regularly maintain and adjust equipment
