[0002] 1. Field of Invention
[0003] This invention relates to a network device for fixed wireless networking, specifically to improving fixed wireless networking deployment.
[0004] 2. Description of Prior Art
[0005] Fixed wireless networking uses wireless communication radios to create digital data network links between multiple networking devices and/or networks. For wireless networking, a pair of wireless bridges connects two remote networks together forms a point-to-point wireless link; an Access Point (AP) communicates with multiple remote Subscribe Units (SU) forms point to multi point wireless connections. Wireless Point Of Presents (WPOP) is built for outdoor wireless network deployment. WPOP works as a central access node for multiple remote wireless networking devices. To perform the networking features, WPOP comprises more than one AP and/or other wireless networking devices to form the wireless links with remote wireless devices; and also, comprises a router and/or ATM switch to interface to wired network. One or more WPOP form a fixed wireless network.
[0006] Radios for wireless networking especially broadband wireless network are different from cellular phone radios. Higher radio frequency (Microwave) is adopted in the wireless networking technology. Line Of Sight (LOS) is needed for the microwave wireless network radio technology. Different wireless networking radios, also are characterized with different radio frequency, gain, and communication protocol. One wireless networking radio can only communicate with other radios under the condition of Line Of Sight, same radio frequency, same communication protocol, and within the distance limited by the transmitting gain regulations.
[0007] Typical WPOP always has wired network connections to link the wired and wireless networks together. WPOP also comprises multiple wireless networking devices, router and/or ATM switch and other support accessories to provide higher bandwidth, more connections to remote clients, and avoid interferences. WPOP usually requires high bandwidth, high reliability connection, such as, T1 or T3 wired connection, or licensed band high-class backbone radio. So WPOP location must be well connected and has physical capability to accommodate multiple expensive electronics equipments. It is very complicate and high costly to setup WPOP.
[0008] WPOP of fixed wireless network serves as a regional center node of wireless links with a limited distance of radiation coverage area. In order to have LOS communicate with remote devices, fixed wireless network WPOP must be located at high geographical locations, such as on the top of a high building or a high tower. However: 1) even though within the WPOP coverage area, a remote device may not be able to communicate with WPOP because of non-LOS. LOS is not always available because of there might be a tall building or other geographical obstacle blocks the link between WPOP and remote device; 2) Remote device site is not always within the coverage of WPOP. In order to get connected, additional WPOP need to be setup as a repeater site. It can be very costly to do it.
[0009] A Fixed Wireless Network Extender (FWNE) device serves as a wireless extension node and improves the deployment of fixed wireless networking greatly. The device comprises system buses on which the networking modules can be attached to; a system processor unit which works as the operation platform also performs networking functions; a radio control unit which can monitor and control radio units; multiple wireless network radio units which connect to the device via PCMCIA control units or system buses directly. By integration of the different types of the wireless network radio units, the FWNE can communicate with multiple different fixed wireless networks, and work as a multifunction fixed wireless networking node. The device can also work as a repeater node to overcome the non Line Of Sight issue and extend the coverage of wireless network.
[0010] Accordingly, several objects and advantages of my invention are:
[0011] (a) to provide a wireless networking device, which is able to perform multiple wireless networking functions in one box;
[0012] (b) to provide a wireless networking device which is able to connect with multiple wireless and wired networks;
[0013] (c) to provide a wireless networking device which is able to connect with multiple different wireless and wired networks;
[0014] (d) to provide a wireless networking device which is able to extend the wireless network range by joint multiple different wireless network together;
[0015] (e) to provide a wireless networking device which requires less installation conditions than the prior art of WPOP;
[0016] (f) to provide a wireless networking device which can be easily deployed to a geographical location to solve the non Line Of Sight issue of the prior art of WPOP;
[0017] Still further objects and advantages will become apparent from a consideration of the ensuing description and accompanying drawings.

[0056] Accordingly, it can be seen that, according to the invention, I have provided a fixed wireless networking device called the Fixed Wireless Network Extender (FWNE), which provides a simple one unit node solution for fixed wireless networking deployment. The device of this invention can be deployed to many locations, which are not applicable to the prior art, and greatly extend the range of the fixed wireless network. The device of the current invention can connect to multiple different wireless networks and function as a key node, which cannot be achieved by prior art. Furthermore, the Fixed Wireless Network Extender (FWNE) device has the additional advantages in that:
[0057] it can be configured with multiple same type of wireless networking units to expend the wireless networking capability of a single node site.
[0058] it can be upgrade from the current wireless network to future generation by only changing the wireless networking radio unit and without changing the whole network system.
[0059] it requires less power, because of one unit design.
[0060] it is more environment friendly by providing the flexibility to reach the place where network needs to go, controversy to prior art needs high gain to penetrate to the remote site to get communicate and emits too much unnecessary radio frequency to the environment.
[0061] it saves the cost when multiple different wireless networks need to joint together.
[0062] it saves the network deployment time a lot by its one unit design.
[0063] it provides higher system reliability than prior art of networking.
[0064] it provides the possibility to connect the wireless network where the prior art cannot reach.
