Internet is a worldwide network of computer networks for public access. Currently, it’s the main mean of mass communication, which gives the user a wide range of potentially informative content and services.
It is a global interconnection between networks of different nature and extent, made possible by a common network protocol suite called “TCP/IP” from the name of the two main protocols, TCP and IP, which constitute the common “language” in which the computers, connected to the Internet (hosts), are interconnected and communicate with each other at a higher level, regardless of the underlying hardware and software architecture and ensuring interoperability between systems and different physical subnets. The advent and diffusion of the Internet and its services have represented a real technological and sociological revolution in the early nineties (along with other inventions such as mobile phones and GPS) as well as one of the drivers of world economic development in the field of Information and Communication Technology (ICT).
In the telecommunications field, WiFi indicates a technology and related devices that enable endusers to connect with each other through a local network wirelessly (WLAN) based on IEEE Standard 802.11.
The local network can be connected to the Internet through a router and use all the connectivity services offered by an ISP (Internet Service Provider).
Any device or user terminal (computer, mobile phone, PDA, tablet etc.) can connect to networks of this type when integrated with the technical specifications of the protocol Wi-Fi.
The Wi-Fi network is a telecommunications network conceptually comparable to a cellular network covering a smallscale (local), with two-way radio devices such as access points (AP) in place of traditional base stations of mobile radio networks (model client-server architecture). The Wi-Fi networks are relatively cheap infrastructure and allow to realize flexible systems for the data transmission using radio frequencies, extending or connecting existing networks or creating new ones.
To increase the area of connectivity of a single access point (approximately 100 m), whose transmission power is limited by specific regulations related to electromagnetic risk (100 mW), are commonly used multiple access points (and related cells coverage) connected by wiring in the local network. For example to cover a boat metal you must use this system architecture as the metal parts block the radio waves by reducing or inhibiting the coverage of AP. The part of the radio interface or radio Access Point-user is the access network, while the wired LAN that connects all the Access Point is the transport network. The coverage cells of AP are often partially overlapped to avoid coverage holes of the signal by creating an area of full coverage, while the wired part is generally an Ethernet network. Each AP are “bridges” and have the task of sending the SSID that identifies the network or networks that are serving to stations radios in their wireless coverage via broadcast, while the set of stations served by the AP is called BSS (Basic Service Set). This network can be connected to the Internet network through a router taking advantage of the relative services internetworking.
System solutions without wiring are possible: connect directly into a wireless access points allowing their communication with exchange of information via radio even with a loss in spectral efficiency of the system.
This kind of system solutions (without wiring) obviously entail costs and construction times significantly lower at the cost of lower connection performance.
The difference between Wi-Fi and the other cellular coverage networks resides in the communication protocols and in the operating frequency (2.4 or 5 GHz); to avoid collisions in the reception protocol is used multiple access CSMA/CA. The Wi-Fi protocols also allow to adapt the transmission speed in the wireless access is according to the distance of the mobile station transmitting by the access point, minimizing transmission losses.
To communicate with receiving stations placed in the coverage of other access points, each station must be able to register/unregister, at the time of connection, to the access point of the call (and possibly reassociate to another AP if the mobile station changes, over time, the coverage cell –handover) which, then informs to the other Access Points its presence and its IP address. In particular, the recording of the station on the access point is made through the sending a normal data packet in which is contained the source address and the destination address.
The installation of antennas (i.e. access point) is simple. They are small antennas inside a box of few centimeters that already contain the necessary electronics and antennas for the operation. Moreover, a Wi-Fi network can have a direct Internet access. In this case the internet system is similar to traditional ISPs providing an access point (the PoP) to users who connect remotely via wireless connection through the so-called hotspots. The source of broadband connectivity where the hot-spot is supported can be wired (ADSL or HDSL), via phone GSM/4G/5G router, via satellite or through a WiFi network. Today there are twoway satellite internet connections that allow high speed data transfer both in download and in upload. The satellite transmission, however, has high latency, the waiting time before it starts sending packets is about 1-2 seconds, much larger compared to the few milliseconds necessary to a 4G/5G connection. Since the source of broadband it’s possible to expand the network through Wi-Fi technology.
The typologies of these antennas are basically two: omnidirectional and directives.
Omnidirectional antennas are usually used to distribute connectivity inside offices, or at least in private spaces and relatively small (this was historically the main purpose for which it was designed the protocol WiFi). Or, with larger operating ranges, you can cover public areas (such as airports, shopping centers etc.).
weBBoat® uses omnidirectional antennas Wi-Fi that are best suited to a boat.
Then, Wi-Fi has evolved to cover larger areas: with the use of directional antennas it is possible to cover large distances, Wi-Fi directional antennas are generally parables, placed on pylons because in the absence of obstacles the access point’s signal covers greater distances. Directional antennas, that amplify the signal of the access point are usable by more users when placed at the top. Typically this type of antenna is used outdoors in infrastructure such as networks in marine.
With an access point with omnidirectional antenna, it can be covered, with broadband, up to a distance of 100 meters (household) if there is no obstacle as the crow flies. In the presence of walls, tre- es or other obstacles the signal decays to about 30 meters..
CERTIFICATIONS
A device, although complying with the standard specifications, cannot use the official Wi-Fi logo if you did not pass the certifica- tion proceduresestablishedbytheWiFi Alliance Consortium (Wireless Ethernet Compatibility Alliance), which tests and certifies the compatibility of wireless components with standards 802.11x (802.11family).

ge that defines a hot-spot. Unlike the phone, the existence of a certified standard ensures interoperability between equipment and network abroad, without the cost of cabling (being wireless technology) for faster and easier installation and subsequent expansion of the network. From this point of view the Wi-Fi, often offered free of charge, is a standard competitor to Internet access via GSM and UMTS cellular networks which have an additional cost. The presence of several producers has created considerable competition by lowering the prices of this technology.
Technicaldisadvantages
The latency time of the Wi-Fi cards –i.e. the time interval that elapses between the moment when an input arrives to the system and the time at which its output is available - is slightly superior to those based on a cable with a maximum latency in the order of 1-3 ms (so it’s negligible, unlike the GPRS/UMTS that have latencies in the order 150 ms). A disadvantage of the Wi-Fi 802.11a/g may be the stability of the service (i.e. the quality of service - QoS) offered to the user, who due to noise on the signal can sometimes be discontinuous (for example the signal may be interfered by microwave ovens that when they are in function disturb the operating frequency of 2.4 GHz, the problem is solved with the use of the operating frequency 5 GHz).
weBBoat® 5G based on the new MIoT router board handle signals based on both 2.4GHz and 5GHz frequencies
Privacy
Most Wi-Fi networks do not provide any form of protection from unauthorized use (authentication), by sniffing the data communication (confidentiality) and on data integrity. This is due to the fact that when purchasing it, the default settings do not require the user to use a security method. Methods to avoid misuse were born together with the development of new technologies and the first system developed was the WEP, Wired Equivalent Protocol, but it is affected by security problems that make it unnecessary. You can suppress broadcast the SSID identification or restrict access to welldefined MAC addresses, but it is easily subject to bypass methods. To overcome these WEP problems, WPA end WPA2 were developed; they offer higher levels of security.
