Suppose, a user has access to two machines with different network connections: wireless and Ethernet. Now he/ she may create a network bridge between the two networks with a third machine which is physically connected to both the machines. However, for successful bridging, the computers that need to be bridged must sit in same logical IP network. Nevertheless, it needs to be remembered that only one Network Bridge can be created on a computer and network bridging is not possible on a machine which runs an earlier version of system software such as Windows 2000 or an even earlier one. Windows XP supports the bridging. In fact, XP provides the software for bridging so the user can save on the hardware.

In contrast to wireless LAN bridging, Client Mode Wireless bridging is different. Segments connected via Client Mode Wireless are unable to share a DHCP server. In case of Client Mode Wireless, Linux based firmware DD-WRT is used for several wireless routers. It connects to the remote router as a client, thus creating two separate subnets. Due to two subnets, the computers within the different subnets cannot see each other directly. Therefore, NAT (Network Address Translation) – which is a technique for preserving scarce internet IP addresses, needs to be enabled between the wireless and the wired ports.

Some benefits of network bridging are:

1. Self-configuring.
2. Basically inexpensive.
3. Helps to reduce collision domain.
4. Above the MAC layer protocols transpiration is possible.
5. LAN connections amongst different networks can be distinguished and barriers such as segment length, number of stations, or repeaters cannot impede the process.
6. Bandwidth usage is reduced.

However, some disadvantages are also there:

1. If the networks comprise of a large range of connection, the bridging may not be appropriate there.
2. Does not limit the scope of broadcasts.
3. Delays may occur because of buffering and processing.
4. Transparent bridges cannot be compatible with types of network topology.

According to the reports, the public areas of the hotel as well as its bedrooms will be provided with access to wireless broadband internet service (Wi-Fi) by the end of the year 2009. This would be a refreshing as well as welcome change for the broadband consumers and customers of BT and Openzone, and the users of O2 Apple iPhone smartphone to surf the web, email and make VoIP calls.

It is also understood that besides these customer groups, the customers from Boingo, iPass and a range of various partners of Openzone would also be allowed to access the wireless broadband services.

According to BT Openzone’s general manager, Chris Bruce, a large number of people expected to enjoy wireless broadband access at selected venues such as Macdonald Hotels and Resorts, whether through smartphones, laptops or other devices, and the company was delighted to welcome to its network, their guests.

Vouchers of BT Openzone will also be sold by Macdonald hotels. This development enables their guests to subscribe to the wireless broadband service for the full duration of their stay at the hotels. Currently, BT has more than 650,00 hotspots across Ireland and the United Kingdom.

The advantage put forward to the users by the Novatel 2352 is its enabling them to share between their multiple WiFi enabled gadget (up to five) mobile broadband signals. These devices cab ne personal computers, laptops, netbooks, games consoles, smartphones, or MP3 players. It is a fact today that today even there exists digital cameras with WiFi features.

The MiFi gadget is all the more significant considering the fact that a data card or a mobile broadband dongle of the present times can only be used by a single person or gadget at a time. Here Novatel 2352 scores by enabling the consumer to share signal between five of the person’s devices simultaneously.

Connecting the Novatel 2352 is also not at all a fussy job, as it carries no software installation to confuse the commoner. This makes it clear that the user can start enjoying the service of the gadget within seconds after unpacking it.

Another merit of the Novatel 2352 wireless broadband device is its impressive tablet shape. The device comes with rotund edges and a glossy black finish explaining a remarkable designing session. The dimensions of the gadget are also appealing as it appears much smaller than many mobile phones of the day.

The WiFi mobile broadband router of Vodafone that is currently not available in the United Kingdom, is capable of allowing customers to create their own WiFi hot spot, which in its turn can connect up to five compatible devices to the wireless network at a time.

The router introduced by Vodafone is expected to allow customers to connect to the mobile broadband network, their WiFi enabled MP 3 players, mobile phones and digital cameras, besides conventional mobile broadband devices such as laptops and netbooks.

Huw Medcraft, the director for mobile broadband at Vodafone Broadband commented on the WiFi hot spot router launch that the mobile broadband hotspot from Vodafone strived to offer families, students and professionals, a single-touch connectivity solution, which turned laptops and MP3 players with WiFi into connected mobile broadband gadgets.

Initially, the Wifi mobile broadband hot spot router would only be available in Spain, Romania and Germany.

Recently, it was the turn of the people living in Norwich welcome the proposal of a fresh internet project according to reports. A fresh WiFi project that can run across the city centre has been proposed by a firm known as Babcock International. This WiFi broadband internet project is expected to start yielding from April 2010, according to a Norwich Evening News report.

The company that has come forward with the proposal could be meeting the business leaders shortly to discuss the WiFi project that could open the floodgates of opportunities for individuals and businesses. It is understood that the company was focusing on key centres in the city such as the UEA (University of East Anglia) campus.

The newspaper had also published the view of the partnership manager at Norwich City Centre, Stefan Gurney that anything that potentially promoted the city for tourism had to be good, and if there was potential to rollout a WiFi network for City College, UEA and the city centre, those were the three spots that could experience high usage.

Meanwhile in Scotland, the public transport is expecting a WiFi broadband access installation in the near future. Under fresh plans here, buses and trains serving the country would be installed with free wireless broadband access with a view to attract more people onto public transport. It is also expected that such a condition would reduce the carbon footprint of the nation.

According to a Scottish government spokesman, Transport Scotland sponsored by the government was already musing over the development of a business case for WiFi provision on ScotRail services, e3ven though the WiFi provision on Scottish buses was solely a matter for private bus operators.
