Some repeater phone can interfere with wireless networks

Almost all users of the phone is in a situation where it left off in the middle of a conversation. Those events are troublesome and often causes the loss of business. This is where they come from our Booster rescue. These are devices that the mobile phone to improve the quality of the received signal and sent to a cell.

The signal strength and wireless coverage depends on a number of variables, such as:

* The distance from a cell tower

Furtheryou are from the tower the poorer is the signal reception.

* Presence of obstacles between the mobile phone and the tower

In case you are in the basement of as high rise the signal reception is greatly reduced and sometimes there's no signal at all.

* The weather

During thunderstorms or rainy weather the signal quality drops considerably.

* Movement while talking

If you are in a moving vehicle you pass from different cellular reception grids and that may affect the call quality.

* Interference from other wireless devices

Wireless signals from other devices like police radios and even EMP generated by the spark plugs of vehicles interrupt the signal flow of cell phones.

Types of Cell Phone Boosters:

There are several boosters available; each designed for specific models.. The most common among them are:

* Internal boosters: These are like paper-thin stickers which are placed under the phone's battery. These 'sticker-like' boosters are easy to install and need no external power source. They effectively enhance reception inside buildings and in densely populated areas.

* External boosters: These are externally attached to the phone with a small antenna. This antenna type booster can be mounted with relative ease. They provide greater signal amplification than their internal counterparts. These boosters are extremely useful inside moving vehicles. They need an external power source and can draw power from a car's power sockets.

* Wireless boosters: These are actually antenna type wireless signal boosters placed at strategically important places to amplify the wireless signal. They are rather bulky, expensive, and complicated with basically three components. They are particularly useful in mountainous regions where the signal is very weak.

With many companies vending their signal boosters you need to be very careful while choosing. Recently some wireless carriers called for a ban on some boosters as cheaper boosters can pose interference threats to some wireless networks. So, if you are not careful enough you may end up with a booster that's incompatible with your cell phone or a booster that's banned in your country.

Comparitive Study Of Types Of Wireless Networks

This article discuses about the various types of wireless networks and the speed, distance of each type of the wireless networks.

1.NARROWBAND WIRELESS LANS:

Narrowband Wireless LANS keep the radio signal frequency narrower and an ability to pass the information along the narrower range. Though the distance through these LANS are reasonable but still speeds available aren't adequate enough fot the corporate users. The major problem that would ocur is interference. But it can be overcome by allowing individual user onto inividual frequencies.

2.PERSONAL COMMUNICATIONS SERVICES:

PCS comprises of a entire range of mobiles, portable and auxilary communication services for both business and personal usage. There are 2 types of PCS as explained below

a. NARROWBAND PCS: The size of the spectrum is smaller than broadband PCS. Narrowband PCS applications include paging, text mesaging, wireless email, wireless telemetry.

b. BROADBAND PCS: This type of PCS has larger spectrum compared to narrowband PCS. Broadband PCS application include all Mobile Telephone services and Mobile Data Services. All these Mobile set of services are available to the users via small. portable, multifunctional devices like digital camera, cellphones etc.

3. SATELLITE: Using satellite networks, the speed would be higher ranging around 1-2 Mbps for upload and download correspondingly. The great advantage of satellite networks are for their huge coverage area, The major drawback of these networks is the delay that exists while connecting. So these networks are found to be nearly dumb when dealt with the bursty traffic.

4. INFRARED WIRELESS LANS: Infrared wireless LANS though have a shorter available range, their speed range are increasing from 115Kbps to 4Mbps. In the near future, usage of Very Fast InfraRed (VFIR) may increase the speed upto 16Mbps. These type of LANS are used in Laptop to PDA transfers and between laptops.

5. SPREAD SPECTRUM WIRELESS LANS: These LANS are a wideband radio frequency technique using LANS. These LANS are both reliable and secure. The most popular WLAN used is 802.11b that runs upto 11Mbps, but the 802.11g specification can boost it upto around 22Mbps.The 802.11a with 5Ghz range can run a bandwidth around 50Mbps which can increase to 100Mbps in the near future. But the distance is less thanwhat we get with 802.11b & 802.11g 2.4Ghz range, (i.e) around 300 feet or so. Usually considering these factors 802.11a is used in a shorter distance outdoor regions while 802.11b/g are used indoors.
