The broadband signals aired by the wireless routers are caught by devices such as netbooks, laptops and gaming consoles that are wireless enabled. Thus the consumer can have wireless broadband internet connectivity across his house and even to some distance outside of it.

Generally, WiFi packages include the wireless router that has already gained popularity among households where more than once device are connected to the web at the same time. Wireless routers enable internet connection for wireless enabled machines such as laptops, gaming consoles and computers.

Wireless routers can be used to make calls through voice over the internet protocol (VoIP), besides facilitating digital television services. The wireless broadband service is largely related to home broadband, although certain routers that can be used with mobile broadband have been developed by Huawei, the popular dongle manufacturer.

The customer can create a wireless mobile broadband network by simply plugging his USB dongle/stick into a wireless mobile broadband router.

This 19.2 kbps speed of data delivery can be even achieved by an idle channel of 30 KHz. The net data rate of CDPD is around 9.6 Kbps. It basically supports TCP/IP protocol and all kinds of connectionless protocols. A wireless featured datagram along with connectionless protocols incorporated in a system which is being used by a mobile phone is the main fact behind the maximum number of users of this CDPD mechanism.

The entire OSI concepts are being used by the CDPD system. Modulation details and transmission of radio waves are related to physical layer. Similarly other layers of OSI too found but never used for any purposes. Three stations that are involved in CDPD are mobile hosts, base stations and base interface stations. Mobile hosts basically act as the portable computers of users. Transmitters come in the name of base stations. All the base stations of CDPD are linked together with the help of base interface stations which can beget  further more transmissions via WAN.

Mainly three types of interfaces are involved in CDPD as E-interface (external), I-interface (internal) and A-interface (air). E is used to make the CDPD to be connected with a network. It can also be used to connect CDPD with a myriad of networks. I-interface is mainly used to interconnect two CDPD with each other. A is responsible for linking mobile hosts with the base stations.

Data transfer over the air interface undergoes certain authenticating processes as data compression, error correction and encryption for security purpose. Data compressions for 274 units and data encryption for 374 bits are applied using error detection and correction methods. For each and every block of bits, flag words of 6 bits are amended so as to make it around 420 blocks of bits. These blocks are further divided into micro blocks each of 60 bits. In cases of full duplex modes, 19.2 Kbps of downlink speed and over 19.2 Kbps of uplink speed are achieved. Hence both uplink and downlink channel allocation are taken place within a micro block which ends after 3.125 msec.

Downlink channel is comparatively easier to access than that of the uplink channels since the uplink channel is tricky in CDPD. Usually all kinds of internet service providers are supported by CDPD. Simply this CDPD is just the extension of traditional data networks which is built over an M-ES (Mobile End System). The message is finally delivered to the F-ES (Fixed End System). For the faster data transfer purposes in cellular devices, it is better to receive with this CDPD.

To connect an external broadband modem, WAN interface can be achieved by configuring one of the Ethernet LAN ports. It is better for the cable or ADSL modem users to get upgraded with the latest 802.11n standard. The speed of wireless coverage of this Bi-PAC wireless router is six times faster than the 802.11 b/g network routers. The wireless coverage is three times greater than those 802.11 b/g devices.

WPS (Wi-Fi protected setup) is also being supported by this router which gives secured wireless network by simply pushing a button with an easier set up process.

The downstream speed of the router is about 8 Mbps with ADSL and 12-24 Mbps with ADSL 2/2+. The upstream speed is about 1 Mbps. These excellent faster data rates are mainly because of the integrated ADSL 2+ modem. Along with this high speed internet connectivity, the users can be able to have fun with online gaming, streaming of their favorite videos and real time audio tracks. The presence of Annex-M doubles the upstream speed of the router. With the configured WAN interface, the user can also use their existing cable / ADSL modem to achieve high speed broadbandconnectivity.

The Billion 7300N Bi-PAC wireless router has an inbuilt default NAT firewall settings with many advanced protection features. Anti-hacker pattern filtering is one among them which detects and prevents the harmful attacks by making use of DoS (Denial of services). Highly secured access control is purveyed with the help of packet filtering process and VPN pass through. It has an auto channel select option too for the convenience of the users. Over traffic problems during the usage of multimedia or P2P on internet can be avoided with the help of fine QoS (Quality of Services). This traffic prioritized QoS is based on IP- protocol, port number and address.

Aspects regarding the management of this Bi-PAC router are very simple and the installation process too easier for the users. DHCP server and client terminologies are being supported by the router and hence the administrators easily integrate the router with the existing network along with password protection.

Bluetooth DUN is a wireless internet technology. This wireless device is used to connect to the internet using Bluetooth enabled cell phone as modem. It is a wireless protocol that enables communication to take place in PAN (Personal Area Network). It mainly uses the frequency hopping technique to transfer data in short distances. To make use of Bluetooth DUN, a Bluetooth laptop along with Bluetooth enabled mobile phone is a must. If Bluetooth is not enabled in your laptop, then Bluetooth adapter can be used. First, switch on Bluetooth on both the devices. The laptop will then detect the mobile phone within the perimeter.

The mobile phone is then connected to the internet using dial up access phone number (which is provided by internet service provider). Once the mobile phone is discovered in your laptop, choose the dial up networking service provider. After selecting this option, Bluetooth adapter will enable the internet access. Another technique of accessing internet is through routers. The router is a network device which interfaces multiple networks. To enable a wireless network, multiple wireless ROUTERS must be placed within specified area, so that internet is accessed through laptop or mobile phones within the area. Such areas are termed as Wi-Fi hotspots. Some examples of Wi-Fi hotspots are airports, coffee shops, libraries, etc.

The main advantage of using DUN is that the technique of accessing internet is used in areas where Wi-Fi is not present. The Bluetooth devices are used instead of modem. It does not require direct line of sight connection. The Bluetooth can be used on different OS. It is very inexpensive as it requires only two devices (a laptop and Bluetooth enabled mobile). The drawback of Bluetooth is that speed is very low. It is in range of kbps. The internet connection through routers requires a modem.

The routers require a WIFI enabled device to access internet. It is too costly when compared to Bluetooth. The main advantage compared to Bluetooth is speed. The speed of router connection is in range of Giga hertz. In router connection, multiple computers can access internet (by forming a network). In Bluetooth connection, the specific device can only access net, which is very slow. The router is used for providing internet within LAN (Local Area Network), WAN (Wide Area Network) and sometimes even MAN (Metropolitan Area Network), whereas Bluetooth is used only for PAN (Personal Area Network). The antenna is main component of router. The powerful antennas are used to boost the signal strength.

The Bluetooth enabled internet connection leads to heavy loss of data packets. The wireless router would minimize data loss and transmit packets efficiently. Both the above devices have advantages and disadvantages. The wireless routers form a major role for high speed broadband connection in WIFI hotspots and thus, cannot be eliminated. From the above facts, it is clearly understood that routers play a pivotal role in high speed internet access and therefore cannot be eliminated.
