- The need for pure bandwidth/speed in areas where there is not (directly) wired infrastructure is present, of course, is the basis of the demand for PtP radio links. The speed with which such a connection can be realized and the associated cost advantages have led to a large market for outdoor wireless connectivity. Sometimes choosing a radio link BESIDE a wired connection, for a lot of redundancy, or temporary additional capacity. Radio systems operate in certain spectrum. Broadly speaking there to distinguish in licensed and unlicensed connections connections. The famous 2.4Ghz and 5GHz band worldwide designated as free band for such applications. Many systems, particularly in the 5 GHz, in both PtP and PmP unlocking consumers and small businesses companies, in many countries on the Internet. ITU makes recommendations on the use for Ether telecom world. National regulators (such as AT and BIPT) will give substance. For many applications licensed frequencies are available, without the transmission constraint and risk of interference that you can expect in 5GHz. (in my next slide about radio frequencies ..) The number of applications of microwave radio is huge and popularity varies by country. Mobile networks and WISP come, internationally the most common. Companies choose for a solution, for example in several higher locations, whether for redundancy. White spots / called "Outside Areas' are places where no (suitable) coaxial or copper is present, or where the distance from the central office / district cabinet (FTTCurb) such that broadband over cable (broadband is 30Mb / s or more) possible is. In the Netherlands, you can, depending on definition, broadband, roughly say that about 5% of the area can be classified as rural areas. This particularly in sparsely populated areas like Friesland, Groningen, Drenthe, Flevoland and Zeeland. There are also specific applications. Without being exhaustive, I would mention: Offshore: Between rigs, platform to shore communication but also fixed-nomadic (production platform to ship), dredging ship to mainland and even mobile. (alternative to Satellite) Broadcast applications: here too, as an alternative to fixed terrestrial or satellite. These include connections from OB / SNG trucks (depending on location) and (IP) between microwave radio transmission towers. Sometimes beam connections are made over multiple hops to cover hundreds of kilometers. Between London and Frankfurt SAF Tehnika realized various compounds for various clients. This is the electronic trading market. Latency is essential. For microwave links this is lower than that for fiber for various reasons.

- Baseband modem, digital modem that input signal (IP) is converted into modulated signal RF Unit / Radio: here the signal being moved and converted to the signal to be transported in High Frequency Antenna: Passive dish which signal is sent and received
- Licensed or unlicensed 2.4, 5, 17, 24 and 60GHz Unlicensed free but transmission constraint and interference risks Licensed: not free but not transmit radio frequency limitation and protection by contract. Channel width is higher licensing tires> more data Telecom Agency: flexible and relatively fast: affordable .. BIPT: prices are higher here The lower the greater the range of the signal The higher the less far, even more influence of weather on range. Higher channel widths to be found at 42Ghz and in 70 / 80GHz (E-Band)
- A free Fresnelzone is essential for a good quality connection. Sites: sufficient height and availability of mounting locations is important. In the Netherlands there are a number of companies operating sites for Telecom radio systems: These are: Alticom 27 towers by Netherlands NOVEC (Tennet daughter), 1500 sites, many in electtriciteitsmasten Shere masts, 460 sites All owners of rooftops of tall buildings (Municipalities) Windmills etc. Indirect connections are possible through the signal, via an intermediate point, "relaying". Relay equipment required less power, alternative sources of energy possible.
- The components visible in the clear 1 + 0 configuration, Baseband modem, digital modem that input signal (IP) is converted into modulated signal RF Unit / Radio: here the signal being moved and converted to the signal to be transported in High Frequency Antenna: Passive dish which signal is sent and received Improve availability and reliability signal: 1 + 1 Hotstandby: everything is duplicated hardware redundancy 2 + 0: radio double for double capacity, can fall back to 1 + 0 In near Line of Sight or risk reflections (Multipath) SD is often used. Spacial Diversity: 2 antennas with best signal is picked up (kind of MIMO antenna principle)
