It transmits a signal similar to Wi-Fi. The signal allows the devices to connect to the internet as well as communicate between each other. WIMAX transmits a signal via tower that resembles a cellular phone tower. These towers can be used to connect to other towers using a microwave likes that works with line of sight. These wireless systems can then be used to connect to the authorized users’ laptops, tablets, dual mode hybrid phones and the other Wi-Fi capable devices..

10 WAYS TO FIX SLOW WI-FI IN YOUR HOME OR BUSINESS.
1. CALL YOUR INTERNET SERVICE PROVIDER OR ISP AND CONFIRM YOUR BANWIDTH SPEED?
The first step to fixing your wi-fi speed, to call your internet service provider and confirm what speeds you are paying for. We also recommend that if the cable that brings service into your home or business has been there for years, you should have your internet service provider replace the cable. Even if you are paying for 1000 gigabit speeds and have the best equipment, you can still have slow speeds with an old cable. All cables loose attenuation over time. It is also a good idea to check the ethernet cable that connects the router to the modem. In some cases, such as gaming or high-performance desktop computers, it is recommended to upgrade these cables to CAT 5 or CAT 6. Depending on the quality of the cables initially installed, the replacement duration can range from 2 to 16 years. We recommend a max of 10 years for optimum performance. If you have a heavy internet workload that consists of several computers or a server runner continuously connecting to a database, you should replace your cables more frequently.
