Pri jej h\u013eadan\u00ed je potrebn\u00e9 sa na cel\u00fa problematiku pozera\u0165 tak z poh\u013eadu technick\u00e9ho ako aj cenov\u00e9ho. V prvom rade je nutn\u00e9 ur\u010di\u0165, pre ak\u00fd typ segmentu je jeden \u010di druh\u00fd typ LAN ur\u010den\u00fd. V podstate je mo\u017en\u00e9 tento segment rozdeli\u0165 na tzv.
\nSOHO (small office\/home office) segment
\nEnterprise – firemn\u00fd segment.<\/p>\n

V skupine SOHO, ktor\u00fa reprezentuj\u00fa v\u00fdrobky dod\u00e1vate\u013eov napr. D-com, D-Link, ZyXel, sa ceny pohybuj\u00fa okolo 15-50.- EUR . Ak uva\u017eujeme o sieti napr. s 20-timi klientami, s\u00fa n\u00e1klady na vybudovanie z\u00e1kladnej infra\u0161trukt\u00fary WLAN v\u00fdrazne ni\u017e\u0161ie ne\u017e pri k\u00e1blovej LAN. Rozdiel vypl\u00fdva hlavne z doby potrebnej na in\u0161tal\u00e1ciu \u0161tandardnej \u0161trukt\u00farovanej kabel\u00e1\u017ee.

V segmente “ Enterprise“, medzi ktor\u00e9 mo\u017eno zaradi\u0165 produkty spolo\u010dnost\u00ed CISCO (Aironet) resp. Agere Systems (Orinoco) dosahuj\u00fa ceny pr\u00edstupov\u00fdch bodov pod\u013ea typu v rozmedz\u00ed 150 -500.- EUR. V pr\u00edpade budovania LAN s pribli\u017ene 100 klientami s\u00fa op\u00e4\u0165 n\u00e1klady na vybudovanie z\u00e1kladnej infra\u0161trukt\u00fary WLAN ni\u017e\u0161ie ne\u017e pri k\u00e1blovej LAN.
\nKedy je teda vhodn\u00e9 pou\u017ei\u0165 bezdr\u00f4tov\u00fa LAN? Je to hlavne v star\u0161\u00edch budov\u00e1ch, kde by mohla mont\u00e1\u017e \u017e\u013eabov p\u00f4sobi\u0165 na prostredie, v tzv. „hot spots“, teda v miestach vy\u0161\u0161ej koncentr\u00e1cie klientov, kde nie je vhodn\u00e1 in\u0161tal\u00e1cia k\u00e1blov – konferen\u010dn\u00e9 miestnosti, zasada\u010dky firiem, vestibuly, kongresov\u00e9 s\u00e1ly, letiskov\u00e9 haly resp. pracovisk\u00e1 umiestnen\u00e9 vo vonkaj\u0161om prostred\u00ed. WLAN je vhodn\u00e1 aj do prenajat\u00fdch priestorov, kde je v kr\u00e1tkej dobe pravdepodobnos\u0165 s\u0165ahovania z\u00e1kazn\u00edka na in\u00e9 miesto.<\/p>\n

R\u00fdchlos\u0165 in\u0161tal\u00e1cie je taktie\u017e dostato\u010dn\u00fdm argumentom v prospech budovania WLAN v porovnan\u00ed s dr\u00f4tovou LAN. Predpr\u00edprava in\u0161tal\u00e1cie ako je mont\u00e1\u017e \u017e\u013eabov, stavebn\u00e9 \u00fapravy (prierazy, sekanie do muriva) resp. n\u00e1sledn\u00e9 uvedie priestorov do p\u00f4vodn\u00e9ho stavu vy\u017eaduj\u00fa svoj \u010das a t\u00fdm aj peniaze. So zvy\u0161uj\u00facou sa cenou pracovnej sily sa cenov\u00fd pomer medzi in\u0161tal\u00e1ciou obidvoch typov LAN bude na\u010falej prehlbova\u0165 v prospech WLAN, nako\u013eko dobu jej in\u0161tal\u00e1cie mo\u017eno vyjadri\u0165 r\u00e1dovo v hodin\u00e1ch, doba in\u0161tal\u00e1cie \u0161trukt\u00farovanej kabel\u00e1\u017ee sa pohybuje r\u00e1dovo v d\u0148och.<\/p>\n
