How To Choose The Best Wireless Access Point And When You Need It?
The aspects of technology in the domain of networking are becoming sophisticated consistently with regular inventions and innovation. One of these technological inventions is Wireless Access Point that is a network capable device having transceiver and antenna for receiving and sending signals from the remote clients. Commonly known as WAP, this technology helps the remote clients to get connected easily and that too with high speed via Internet. WAP technology has given global connection its real meaning.
Why you need Wireless Access Point?
WAP technology is ideal for sharing broadband Internet connection with many computers. This wireless sharing is meant for within the household that also functions with your existing modem router but for which you need to make sure that your modem includes either firewall NAT feature or wireless router.
Where installation of network cable is merely impossible, WAP rescues you here with its wireless access to the network. For the sake of business enhancement, WAP is the best option to choose. You need Wireless Outdoor Access Points in harsh plant environment with which you can create mesh network, point-to-point and point-to-multi point networks. You can also create hotspots with security separation, when you need mobile devices to wirelessly access the network.
Selection of the best Wireless Access Point
Constant innovation in WAP Technology by Manufacturers has guaranteed a high-performing product that serve in the best possible manner. Due to consistency in innovation, selecting the best Wireless Access Point is a challenge. You can go through these below mentioned features that should be a must in your Wireless Access Point.
WDS Support
A perfect Wireless Access Point should support Wireless Distribution System (WDS). It helps a wireless network to expand by utilizing multiple access points that too without requiring an urge for a wired backbone to link them. WDS enables you to develop a wireless infrastructure as the network equipment becomes independent from wired LAN. With WDS feature, you can develop an enormous wire network by connecting various wireless access points with WDS links. It is used mostly in larger area where pulling wire is literally impossible.
Multifunction Modes
This is a vital feature of WAP. The best Wireless Access Point should connect with different operational modes such as Network Bridge, Access Point, Wireless Client Mode, and Network Bridge. When multifunctional modes are considered, the thing need to be taken care of is that the device is compatible with existing wired network that functions well by simple attachment with modes by Ethernet cable to an unenclosed port in your switch or router. With Wireless Ethernet Bridge Mode or Client mode, you can connect your notebook, PC, printer, network camera to the AP device by the help of switch. In repeater mode, you can make addition in AP devices that extend the wireless network that too without requiring any run backbone cables.
Technically Advanced Security Features
A sophisticated Wireless Access Points should be compatible with security features like advanced wireless security Wireless Protected Access (WPA/WPA2), SSID Broadcast Control, and MAC filter. When deployment in Corporate Network is considered, Access Points should sustain technically advanced RADIUS authentication and wireless protection (EAP-MD5, EAP-TLS, EAP-TTLS, and PEAP), Wireless Protected Setup (WPS) that assure trouble free installation.
Wireless N
Presently, there is a high standard wireless technology that includes the wireless 802.11n. This standard is the most advanced and thus fastest wireless technology accessible in the market. For applications like High Definition Video streaming and voice, dual-band version of both 2.4 GHz and 5 GHz frequency bands is the perfect choice. Equipped with wireless N and MIMO technology, the Wireless Access Point offers longer distance coverage with the speed up to 300 Mbps or more.
About Installation of Wireless Access Point
Mostly, Wireless Access Point is designed and developed for indoor purposes where the working environment is not constrained. There is also specific design available for outdoor installation having rugged housing, high grade industrial components, and weather proof, rust resistant, and water-tight enclosure. WAP designed for outdoor application can operate under the strenuous temperature range of -30°C to 70°C.

Pull up resistors to a data line?
I am using a 2 Mbps data line from a wireless transceiver.
The circuit power is at 3.3V Vdd; what sized resistor do you recommend I connect the line through to Vdd in order to improve signal integrity?
Thanks in advance.
The connection is a short route between a PIC uC and a wireless tranceiver (http://www.quasaruk.co.uk/acatalog/RFM70.pdf), so a short and simple IC to IC connection.
That highly depends on the specifics of your circuit, how much the drivers can source/sink, the load of the input... If it's properly designed 2Mbps should be no issue.
