This relatively low level of network demand fits well with the capab ilities of LoRaWAN. ther apps with demands or high andwidth and low latency may e etter serv ed cellu lar alternativ es. owev er, applications prov iders and city au thorities do not need to agree to long contracts with cellu lar prov iders or estab lish indiv idu al networks or each of the low andwidth, inf req ent se cases. nstead, they can own a priv ate LoRaWAN ov er which they can ru n many of the applications listed elow. ity au thorities need inf ormation to e ab le to plan or tu re demand or their serv ices and to ensu re the saf ety and improv ed ality of lif e or citiz ens. LoRaWAN-enab led sensors can collect and commu nicate critical data in areas, su ch as temperatu re, hu midity air ality ib ration and noise. amples of these inclu de monitoring temperatu re to decide whether to salt roads in winter; monitoring nitrogen ox ide lev els to plan or redu ction in the env ironmental impact of traffic; monitoring of humidity to fight damp within ildings; and monitoring or ex cess noise lev els. All of this data can e collected and acted pon, and additional sensors, su ch as ones emb edded in roads, can prov ide inf ormation on the salt lev el on a particu lar road and thereb eliminate wasted re-salting. ther ex amples of monitoring inclu de sensors on waste ins to alert when a in is ecoming ll, so it can e emptied when req ired, rather than as part of a weekly routine in which some bins are overflowing and others are arely sed. n addition, soil sensors can e sed to determine when pu lic parks or sports grou nds req ire irrigation, and rainfall sensors can be used to trigger flood def enses or emergency su pport or citiz ens. ch of the data collected can e analy ed alongside historical data to enab le trend analy sis and predictiv e action to be taken, thereby increasing efficiency and improving citiz ens' liv es. owev er, smart cities are not only ab ou t the collection of data. Activ ation of nctions is also req ired. amples of this inclu de the control and maintenance of streetlighting,
