Abstract

A powerline signal test apparatus has a housing, a pair of prongs protruding from the housing, a powerline module coupled to the pair of prongs within an interior region of the housing. The powerline module is configured to process a first data signal in a first format. The apparatus further has a processor coupled to the powerline module. The processor is configured to initiate transfer of first test data characterized by a first data rate from the pair of prongs through a portion of a powerline network to a target node and initiate receipt of second test data characterized by a second data rate. Moreover, the apparatus has a signal strength indication for the portion of the powerline network associated with the second test data characterized by the second data rate. Furthermore, the apparatus has an output device coupled to the housing and configured to output the signal strength indication.

Claims

1. A powerline signal test apparatus comprising:

a housing;

a pair of prongs protruding from the housing, the pair of prongs including a first prong and a second prong to be inserted respectively into an AC powerline outlet;

a powerline module coupled to the pair of prongs and within an interior region of the housing, the powerline module being configured to process a first data signal in a first format;

a processor coupled to the powerline module and provided within the interior region of the housing, the processor being configured to initiate transfer of first test data characterized by a first data rate from the pair of prongs through a portion of a powerline network to a target node, the processor being configured to initiate receipt of second test data from the target node characterized by a second data rate, wherein the second test data is an acknowledgement to the first test data;

a signal strength indication for the portion of the powerline network associated with the second test data characterized by the second data rate;

an output device coupled to the processor, the output device configured to output the signal strength indication.

2. The apparatus of claim 1 wherein the housing has a width of less than six inches and a length of less than ten inches.

3. The apparatus of claim 1 wherein the output device comprises an LCD display, the LCD display comprising a graphical representation of the signal strength indication.

4. The apparatus of claim 1 wherein the first data rate is at least 14 MB per second, 85 MB per second, 200 MB per second, 400 MB per second, or 1000 MB per second.

5. The apparatus of claim 1 wherein the second data rate is less than the first data rate.

6. The apparatus of claim 1 further comprising a data port coupled to the housing, the data port being coupled to a computing device, the computing device comprising a display, a central processor, a volatile memory, and a data bus, the data bus coupled to the data port, the computing device configured to output a graphical representation of the signal strength indication.

7. The apparatus of claim 6 wherein the data port comprises an 10/100 RJ-45 type Ethernet port, or a USB port.

8. The apparatus of claim 1 wherein the housing comprises a molded plastic material to enclose the powerline module and processor, the molded plastic material having an exterior region, the exterior region comprising the output device, which comprises an LCD display or one or more LED devices, the LCD display or one or more LED devices being coupled to the processor via a driver coupled between the LCD display or one or more LED devices and the processor.

9. The apparatus of claim 1 further comprising a software utility module, the software utility module being configured to instruct the initiation of the transfer of the first test data characterized by the first data rate.

10. The apparatus of claim 1 further comprising a software utility module, the software utility module being configured to instruct the initiation of the transfer of the first test data characterized by the first data rate and being configured to instruct the initiation of the receipt of the second test data.

11. A method for determining signal strength of a powerline network, the method comprising:

providing a powerline test apparatus, the powerline test apparatus comprising;

a housing;

a pair of prongs protruding from the housing, the pair of prongs including a first prong and a second prong to be inserted respectively into an AC powerline outlet;
