Using Twisted-Pair Homeplug

Introduction

As I’ve discussed elsewhere, TP (Twisted Pair) Homeplug products are networking products which allow Homeplug networking down standard twisted pair wire. The advantages of Homeplug over more dedicated cabling, compared to over active mains cables (which is the type of Homeplug networking 99.9% of users know of), are much higher data transmission rates and longer cable runs. The electrical noise invariably present on normal mains wiring and the complications present in how the cable is distributed (spurs, consumer units etc) often limits the effective data speed and also restricts the length of cable runs you can get away with. But Homeplug over twisted pair wire, with it’s simpler, cleaner interconnect can, for example, give TCP data throughputs in excess of 25Mbps with cable runs of 500m. In our own office testing we got speeds from 95Mbps (the theoretical limit for the devices) with a short cable, down to 15Mbs with a 700m run.

Direct (4m of twisted pair) 95Mbps
200m twisted pair 71Mbps
500m twisted pair 25Mbps
700m twisted pair 15Mbps

Applications for TP Homeplug are anywhere where there is the option of using a single pair of twisted cable as the infrastructure. This can, for example, be a used or unused wire pair in multi-pair telephone cable, an unused wire pair in alarm cable, or an unused pair in network cable.

Real World performance of Solwise HomePlug powerline data transfer devices

If you are having trouble getting a HomePlug setup to deliver the through-put that you need, or if you are trying to determine what you can expect from some products that you are thinking of buying, then the following notes may help.

There are four main considerations that affect the performance of a HomePlug system:

  1. The distance between the pair of devices
  2. The complexity of the building’s mains wiring
  3. Electrical noise generated by other mains powered equipment
  4. Understanding the headline speed of the standard

Before we look at these points in detail we’ll have a quick look at the technology in general.

Antenna Considerations for 4G/LTE

Objective
To try and clarify factors that you need to consider when planning on using an external antenna for your 4G/LTE broadband connection.
With 4G (LTE) services starting to come onto the UK market a lot of users are finding that they are achieving download speeds that are lower than they were expecting to get. Often this can be due to poor reception however there are other factors that need to be understood which can affect the broadband speed.

Hopefully this short article will help explain the implications and considerations the user needs to examine before they can decide the best course of action.
