Difference Between Wi. MAX and Wifi Wi. MAX vs Wifi. Wi. MAX and Wi- Fi are both wireless technologies but Wi- Fi can only be operated in short ranges (Max 2. Wi. MAX could be operated in long ranges (around 3. Km). Wi. MAX has fixed and mobile version which could be used for several applications with higher bandwidth (around 4. Mbps). Like DSL or Cable internet in cities, Wi. MAX could be a cable broadband replacement in rural areas where most providers don’t have copper network to offer DSL services.
802.11ac equipment also communicates with each of these others. And 4. 0 Mbps is much faster than even ADSL2+. Triple play services like voice, video and data could be easily offered over Wi. MAX. The new version of Wi. MAX 8. 02. 1. 6m is expected to deliver 1 Gbps which is equivalent to Fibre to Home and it’s very useful for backhauling of remote offices or provider access stations. Wi. MAX (IEEE 8. 02. Wi. MAX (8. 02. 1. Wireless Interoperability for Microwave Access) is a 4th Generation mobile access technology for high speed access. The current version of this technology can provide around 4. Mbps in reality and the updated version is expected to deliver 1. Gbps in fixed endpoints. Wi. MAX falls under IEEE 8. Wi. MAX expected wave 1, 1. Here are the latest articles published on Tom’s Hardware. See the latest news, reviews and roundups and access our tech archives. Gbps in fixed endpoints. Wi. MAX has fixed version and mobile version. The fixed Wi. MAX version (8. The Wi. MAX mobile version (8. GSM and CDMA technologies. Wi- Fi (IEEE 8. 02. Wireless Fidelity (Wi- Fi) is a wireless LAN technology which could be used in short range. Wi- Fi operates in 2. GHz or 5. GHz which are unallocated frequency band (Specially allocated for ISM – Industrial Scientific and Medical). Wi- Fi (8. 02. 1. Home Case studies Frequencies Standards Tools Training Training modules: Introduction Manual monitoring Role of monitoring Inspection Bandwidth FCO Spectrum Control.GHz frequency and range from 4. GHz with OFDM modulation technology thus results higher speed (4. Mbps in reality) ranged to 7. We can easily setup a Wireless LAN (WLAN) at home with Wireless Routers. When you setup Wi- Fi at home make sure you enable security features on it to avoid 3rd party access. Couple of them are, Secure Wireless or Encryption, MAC address filter and more than these don’t forget to change the default password of your wireless router. Difference between Wi. MAX and Wi- Fi(1) Both operates in Microwave frequency range to offer wireless access(2) Wi- Fi a short range technology mostly used in, in- house applications whereas Wi. MAX is a long range technology to deliver wireless broadband to far end.(3) Wi- Fi is mostly an end user technology where users can purchase Wi- Fi devices and configure them by themselves and Wi. MAX is mostly deployed by service providers.(4) Wi- Fi uses CSMA/CA protocol which could be connection based or connection less whereas Wi. MAX uses connection oriented MAC protocol.(5) Wi- Fi is a wireless LAN technology and Wi. MAX is a wireless LAN technology (WLAN). Wi. MAX and Wi- Fi Comparison. Wi. MAX is similar to the wireless standard known as Wi- Fi, but on a much larger scale and at faster speeds. A nomadic version would keep Wi. MAX- enabled devices connected over large areas, much like today’s cell phones. We can compare it with Wi- Fi based on the following factors. IEEE Standards. Wi- Fi is based on IEEE 8. Wi. MAX is based on IEEE 8. However, both are IEEE standards. Range. Wi- Fi typically provides local network access for a few hundred feet with the speed of up to 5. Mbps, a single Wi. MAX antenna is expected to have a range of up to 4. Mbps or more. As such, Wi. MAX can bring the underlying Internet connection needed to service local Wi- Fi networks. Scalability. Wi- Fi is intended for LAN applications, users scale from one to tens with one subscriber for each CPE device. Fixed channel sizes (2. MHz). Wi. MAX is designed to efficiently support from one to hundreds of Consumer premises equipments (CPE)s, with unlimited subscribers behind each CPE. Flexible channel sizes from 1. MHz to 2. 0MHz. Bit rate. Wi- Fi works at 2. Hz and can peak up to 5. Mbps in 2. 0 MHz channel. Wi. MAX works at 5 bps/Hz and can peak up to 1. Mbps in a 2. 0 MHz channel. Quality of Service. Wi- Fi does not guarantee any Qo. S but Wi. Max will provide your several level of Qo. S. As such, Wi. MAX can bring the underlying Internet connection needed to service local Wi- Fi networks. Wi- Fi does not provide ubiquitous broadband while Wi. MAX does. Comparison Table. Freature. Wi. Max(8. Wi- Fi(8. 02. 1. 1b)Wi- Fi(8. Primary. Application. Broadband Wireless. Access.
