Sharing hotspot connection with a game console


What you need to get started:
  1. Console – must have a Wi-Fi adapter
  2. Wireless Access Point (AP) – with an Ethernet port available
  3. Laptop – Wi-Fi ready with a free Ethernet port.
  4. Hotspot coverage
  5. Windows OS – with Internet Connection Sharing (ICS)
Our environment:

Console: My son's PSP 3000
Access point: TRENDnet TEW-432BRP wireless router
Laptop: Lenovo ThinkPad T500
Windows OS: Vista SP 1

Step 1: Configure access point

Disable DHCP service on the AP.
Assign 192.168.0.x to the AP LAN address where x is any number greater than 10. ICS will set LAN address on the laptop to 192.168.0.1 – more on this later. We set our AP LAN address to 192.168.0.100.

Step 2: Configure console

IP address: 192.168.0.n (set n to any number other than 1, we set our PSP IP address to 192.168.0.7)
Subnet mask: 255.255.255.0
Gateway address: 192.168.0.1
Do not assign addresses to DNS and DHCP servers

Step 3: Configure laptop

Enable internet sharing on the wireless adapter (not the LAN port).
The LAN port is automatically assigned IP address 192.168.0.1 and subnet mask 255.255.255.0.
Confirm that the Internet Gateway device is assigned IP address 127.0.0.1 (local loop address). For Windows Vista users: Control panel -> network and sharing centre -> view computers and devices -> properties.

Step 4: Connect

Connect laptop to available Wi-Fi hotspot.
Connect fly lead (Ethernet cable) from laptop to access point LAN (not WAN) port.
Connect console to your wireless AP.

Step 5: Commission the network

Hand over the console to your daughter.
Give yourself a pat on the back.
Now go and do some real work...

Want to test midlets on real phones?

Most mobile phone manufacturers offer emulators to help developers with software tests. Java and C++ programming environments usually provide plug-in facilities for emulators . Products such as Pulsar go a step further to integrate and maintain the entire development space. Although emulators catch a fair amount of design and runtime errors, software behaviour on real phones is unpredictable. For most developers it is not financially feasible to test the behaviour of their mobile applications on all target platforms. To get around this obstacle some companies offer on-line services that allow for application testing on real devices. These services are often expensive. In software provided by phone manufacturers multiple instances of the emulator are invoked to simulate the behaviour of federated handsets. One solution is to run an instance of the application on a PC and set up a local communication channel with a real phone. A neat, inexpensive and elegant solution is availab

Whose Shilling?

Image
Zimbabwe is Africa's Lazarus. The economy is in tatters, the citizenry of this great nation are despondent but Robert Gabriel Mugabe remains firmly in charge. For the time being. Many believe that only South Africa is in a position to determine the destiny of Zimbabwe. Yet President Thabo Mbeki, save for his quiet diplomacy, appears disinterested in employing enough downward pressure for Mr. Mugabe to repent his sins and thereby rid the Zimbabweans of their current economic woes. What exactly does Mr Mugabe have on Mbeki? In exile Mbeki lived, at different times, in the United Kingdom, Botswana and Zambia. He hardly was guest of the Mugabe's. On that score alone, Mbeki does not owe Robert a good turn. Of the two neighbours, Zimbabwe is most reliant on the other. Zimbabwe relies on South Africa's ports for her exports and imports. She draws electricity and routes her telecommunication traffic through her southern neighbour. South Africa is one of Zimbabwe's m

Free mobile-to-mobile calls

A mobile phone is a miniature telephone exchange. It accepts incoming calls, initiates outgoing calls and can act as a repeater by forwarding calls or as a switch through teleconferencing. These are the basic features of a telephone exchange. TerraNet , a Swedish firm, has exploited these features to facilitate free mobile-to-mobile calls. Using peer-to-peer technology, a cluster of mobile phones can communicate without the need to go through a base station (switch) provided they are within 1,000m of each other. This technology, being trialled in Ecuador and Tanzania, is perfect for developing countries where infrastructure is as limited as disposable income. Because mobile phones can forward calls, the effective communication distance can be extended from a 1 kilometer radius to about 20 kilometers. That is sufficient to cover most rural communities and, for example, university campuses. Like Skype , this is a subvertive, effective and disruptive technology. While manufacturers
